Description

  The present invention is installed on a road surface such as a center line of a road, the center of an intersection, and a pedestrian crossing, and emits a light emitting body such as a light emitting diode by energization by a power supply device or the like to warn a road driver such as a vehicle driver or a pedestrian. This is related to a self-luminous roadway that aims to prevent traffic accidents by guiding the eyes and eyes.

  For example, in Patent Document 1, a light transmissive panel whose upper surface is installed on substantially the same plane as a road surface, a solar battery provided below the light transmissive panel, a storage battery charged by the solar battery, and the storage battery A planar self-luminous light source having a plurality of light emitters that are turned on as a power source, wherein the light emitter has an angle between an optical axis of the light of the light emitter and the lower surface of the light transmission panel within 5 degrees. In addition, since the optical axes of the light emitters are formed in an intersecting relationship, the light of the emitter is refracted and incident on the lower surface of the light transmission plate and travels through the light transmission plate. The light is refracted at an angle between the optical axis of the light and the lower surface of the light transmitting plate and emitted into the atmosphere, so that the illuminant light reaches far along the road surface and the optical axis of the illuminant light is changed. By arranging the light emitters that radiate in multiple directions close to each other, Planar self-luminous rivet is disclosed that.

  However, in the flat self-luminous lamp as described in Patent Document 1, when installed at the center of the intersection, the light emitting the attention is given to each direction, but the line of sight of the road user and the optical axis of the luminous body at the time of installation If they are out of alignment, the attractiveness may be extremely lowered, and if it is installed in the wrong direction, it will be buried in the road surface, which makes it very difficult to correct the direction of the optical axis. In addition, the presence of the self-luminous lamp is emphasized by the flashing of the illuminant, but, for example, each illuminant continues the same flashing state (simultaneous flashing) at the same timing so that only the same illuminant continues to flash In some cases, the illuminant simply keeps blinking, and sufficient attractiveness may not be obtained especially when a road user approaches.

  The present invention has been made in view of the above-described problems, and provides a self-luminous roadway that does not require time and effort for adjusting the direction during installation, and that can provide high attractiveness even when a road user approaches. It is something to be done.

In order to achieve the above-mentioned object, the present invention has an eaves body embedded in a road surface, a translucent body placed on the eaves body, and a light emitting unit, and light emitted from the light emitting unit when energized. A plurality of light emitters arranged in parallel along the circumferential direction of the bag main body so as to be emitted to the outside through the light transmitter, and a control device for controlling energization of the plurality of light emitters, The control device is configured so that one of the plurality of light emitters, or one of the plurality of light emitter groups composed of two or more adjacent light emitters, is turned on one by one in the circumferential direction. The energization of the plurality of light emitters is controlled so that the plurality of light emitter groups flow and blink by sequentially shifting to the side, and the main body is parallel to the peripheral portion along the circumferential direction or Having a planar region formed substantially parallel It is embedded in the road surface such that the planar region faces upward and is parallel or substantially parallel to the road surface, and the light transmitting body is formed on the upper surface of the light transmitting body. Continuously along the circumferential direction inclined with respect to the optical axis of the light emitter, radially outward from the position of the light emitter and radially inward at a predetermined distance from the edge of the light transmitter The inclined light emitting surface is formed and is placed so as to cover at least all or part of the planar region of the bag main body along the circumferential direction. Along the circumferential direction so that the light emitting portion faces outward from a position above the planar region of the collar body and below the top of the light transmitting body, and radially inward from a position covering the planar region. Arranged from the light emitting part of the light emitter through the inclined light emitting surface. The first light is emitted to the outside, and the second light is emitted to the outside through the upper surface portion of the translucent body after being reflected from the light emitting portion of the light emitter to the planar region of the bag body. It is characterized by this.

In this onset Ming spontaneous light road studs, that light emitters arranged in plural and in sitting in a circle shape without defining the direction of the optical axis of less strictly emitters during installation, either emitters road usage It is possible to emphasize the presence of road fences by radiating light toward the person, and by further flashing and flashing the luminous body, it is possible to obtain a higher attractiveness than when the luminous body simply flashes. it can. Further, in the second self-luminous road fence, since the light emitters are juxtaposed along the circumferential direction of the fence main body even if the direction of the optical axis of the light emitter is not strictly defined at the time of installation, either The illuminant can radiate light toward road users such as vehicle drivers and pedestrians to emphasize the presence of road fences, and the illuminant flashes in the above-mentioned manner so that the illuminant is simple. Higher attractiveness can be obtained than when only blinking.

If the if the light emitter in the spontaneous light road stud is provided 8 body or more, a second light emitter groups over the plurality of light emitters group 8 group in spontaneous light road studs, emission The probability that any one of the bodies will be in the field of view of the road user is increased, the installation of the road fence is easier, and the flow flashing looks smooth, which is preferable. Further, since light is emitted in eight or more directions, and in the second self-luminous roadway, in the case where there are two or more light emitters in one light emitter group, the directions are 16 directions or more. For example, it can be suitably used not only for the usual four-difference road but also for any intersection such as a three-difference road or an intersection of five or more roads.

Before Symbol the flowing flash in spontaneous light road stud is the one where the sensing means approaching of the vehicle is performed when it is detected, by changing the light emission mode otherwise as when approaching the vehicle, the light emission mode It is preferable that the attractiveness can be further enhanced by the difference between the two, and that the light emission mode is changed with the approach of the vehicle so that the approach of the vehicle can be notified to a pedestrian or a bicycle driver who passes in the vicinity. In addition, if the second self-luminous road fence further includes sensing means for detecting the approach of an approaching object, the control device can detect the road user (for example, a vehicle or a nearby vehicle). Illuminating mode when the approaching of the approaching object such as a pedestrian or bicycle driver who is approaching or not, and further speaking, when the approach of the approaching object is not detected by the sensing means, the light emission of a predetermined condition is performed. When approaching of an approaching object is detected by the sensing means so as to be in one light emission mode, the light emission is in a condition different from the first light emission mode, and at least the second light emission mode in which the flow blinks is performed. By controlling energization of the plurality of light emitters so as to return to the first light emission mode after a predetermined time has elapsed, the attractiveness can be further enhanced by the difference in the light emission modes. At the same time, when the detected road user (for example, a vehicle or a pedestrian or bicycle driver who passes nearby) approaches the light emission mode, other road users (for example, pass nearby). A road user (for example, a vehicle or a pedestrian or bicycle driver who passes nearby) detected by a pedestrian, a bicycle driver, or a vehicle) can be notified in advance, and a higher alerting effect can be obtained. Can be preferable. The predetermined time may be a time that can alert a road user, for example, but not limited thereto, and may be about 10 to 30 seconds.

Prior Symbol spontaneous light road studs, as the first and specific aspects of the second light-emitting mode, wherein in the first light emitting mode, a predetermined first period of light emission (e.g., followed by the same flashing at the same time Simple flashing (hereinafter referred to as simultaneous flashing) and light emission including the flow flashing), and in the second light emission mode, light emission in a second cycle faster than the first cycle (for example, simultaneous flashing, flow flashing, etc.) And the case where at least the flow flashing is performed. In this case, the luminance in the second light emission mode may be greater than the luminance in the first light emission mode. Further, the luminance of the corresponding light emitter group may be changed or the color scheme may be changed according to the road conditions in the direction of emitting light in the plurality of light emitter groups. When changing the luminance of the luminous body group, in order to make the second luminance brighter than the first luminance, for example, the power supplied to the luminous body in the luminous body group may be changed, or / Furthermore, when there are a plurality of the light emitters in the light emitter group, the number of the light emitters to emit light may be changed.

  Examples of the first period include about 300 msec / time to about 1000 msec / time, and examples of the second period include about 1 / 1.5 to 1/7 of the first period. However, the present invention is not limited to this. The lighting time of each luminous body group may be about [first period / number of groups] in the first period and about [second period / number of groups] in the second period. It may be smaller than [first period / number of groups] at one period and smaller than [second period / number of groups] at the second period.

  The sensing means may be provided in the main body of the fence, and apart from the main body of the fence, for example, when a road user at a far distance cannot be detected due to the sensitivity of the sensing means, it is far away. It may be provided at a predetermined distance from the bag main body so that a road user at a distance can detect it. When the sensing means is provided in the bag main body, it is preferable that a plurality of the sensing means are provided in parallel along the circumferential direction. By doing so, the detection range in the circumferential direction of the road user can be widened. When the sensing means is provided separately from the bag main body, the detection signal from the sensing means can be transmitted to the control device by, for example, a wireless or wired communication means.

  Any sensing means may be used as long as it can detect the approach of an approaching object. For example, the sensing means receives an infrared ray from an approaching object that emits infrared light such as a pedestrian, a bicycle driver, or a vehicle. And a photo-semiconductor sensor that receives light from an approaching object such as a vehicle or a bicycle whose headlamp is turned on in the evening or at night. Among them, the detection sensitivity of the photo semiconductor sensor is not limited to this, but for example, in the case of a vehicle, the headlight can be about 30 m to 40 m with a low beam and about 100 m with a high beam.

  The saddle body has a planar region formed in the peripheral portion in parallel or substantially parallel to the circumferential direction, the planar region facing upward, and parallel or substantially parallel to the road surface. As shown in the figure, those embedded in the road surface can be exemplified. In this case, the translucent body is radially outward from the positions of the plurality of light emitters on the upper surface of the translucent body, and radially inward at a predetermined distance from the edge of the translucent body. And having an inclined light emitting surface continuously formed along the circumferential direction inclined with respect to the optical axis of the light emitter, and at least all or a part of the planar region of the bag main body is the circumference. The light emitters are placed so as to cover along the direction, and the plurality of light emitters have diameters higher than a position of the planar region of the bag body, below a top portion of the light transmitting body, and from a position covering the planar region. It is preferable that the light emitting units are arranged side by side along the circumferential direction so that the light emitting units face outward. In such a road fence, the first light can be emitted from the light emitting part of the light emitter to the outside through the inclined light emitting surface, and the planar region of the fence main body from the light emitting part of the light emitter. The second light can be emitted to the outside through the upper surface portion of the translucent body. Here, it is desirable that the planar region has a higher light reflectance. For example, as the material of at least the planar region of the heel body, a material that improves light reflectivity by polishing (for example, a metal such as an aluminum alloy die cast) may be employed, and the planar region may be polished, You may provide the sheet | seat etc. with comparatively large light reflectivity in the said planar area | region at least of the said main body. By doing so, the light reflectivity of the planar region is improved, and the amount of the second light can be increased. At this time, the inclined light emitting surface from which the first light can be emitted is formed radially inward at a predetermined distance from the edge of the translucent body. The second light can be emitted at a predetermined distance. The elevation angle of the light beam of the first light is not particularly limited. However, the elevation angle of the first light beam may be effectively visually recognized so as to be substantially coincident with the line-of-sight angle when viewed from a vehicle driver mainly 50 m or more away. It is preferable to make it as small as possible to about 5 to 5 degrees. The elevation angle of the second light beam is preferably about 15 to 90 degrees so that a road user such as a nearby pedestrian or bicycle driver can easily see. By carrying out like this, it is excellent also in not only the vehicle driver among road users but also a pedestrian etc., and alerting power can be improved. The light emitter may be arranged such that the optical axis is parallel or substantially parallel to the planar region, or the optical axis may be arranged obliquely upward or obliquely downward. For example, the visibility can be improved by adjusting the direction of the optical axis according to the situation, the amount of leakage light to the outside, or the amount of reflected light from the planar region or the like.

Prior Symbol spontaneous light road studs, said plurality of further comprise a power supply for energizing the light emitter, the power supply, under the direction of the control device, even when energization of the plurality of light emitters Good. In this case, as the power supply device, for example, a solar battery and a storage battery are included, and power can be supplied from the solar battery to the storage battery only when the generated power of the solar battery exceeds a predetermined amount. A configured power supply can be mentioned. Of course, the second self-illuminating road fence using such a power supply device may be lit regardless of day or night, but considering the power generation capability of the solar cell and the charging capability of the storage battery, In particular, it is preferable that the light emitting operation is performed only when the surroundings are dark, such as in the evening or at night.

  As described above, according to the present invention, a plurality of light emitters are arranged in a vehicle seat shape without strictly specifying the direction of the optical axis of the light emitter at the time of installation. The user can radiate light toward the user to emphasize the presence of the roadside, and the luminous body will flow and flash, making it much more attractive than if the luminous body simply flashes. Obtainable.

Embodiments of the present invention will be specifically described below with reference to the drawings.
(First embodiment)
FIG. 1 is a top view showing a first embodiment of a self-luminous road fence according to the present invention. A translucent body 2 is attached to the main body 1, and a light emitter 3 is disposed in a vehicle seat shape below the translucent body 2, and a light emitter disposed in a vehicle seat shape at a substantially central portion of the translucent body 2. A circular protrusion 21 is formed so as to be surrounded by 3, and an inclined surface that forms the protrusion 21 is a light emitting surface 22 that emits light toward a road user. Further, below the protrusion 21, a solar cell 4 for generating electric power related to light emission of the light emitter 3 is provided, and a self-luminous roadway 10 is formed.

  Since the eaves body 1 is embedded in the road surface, it is usually made of a metal such as an aluminum die cast having excellent strength, corrosion resistance and formability. The translucent body 2 is a hard transparent material excellent in impact resistance, scratch resistance, weather resistance, etc. so that it does not break even if a vehicle or the like rides on the translucent body 2 and the light of the light emitting body 3 is transmitted. It is generally produced from a synthetic resin having translucency such as glass, polycarbonate, and acrylic resin. Therefore, the light emitted from the light emitter 3 is emitted not only diagonally forward but also from the leaked light, and the light emission state can be confirmed from a pedestrian, a bicycle or the like who visually recognizes the self-luminous road fence 10 from above. Is.

  As the light-emitting body 3, a light-emitting diode, a halogen lamp, a metal halide lamp, a cathode tube, electroluminescence, a xenon lamp, or the like is appropriately used. In general, a light-emitting diode having strong directivity and high luminance is preferably used. Another reason why light-emitting diodes are used is that the power supply voltage required to cause the light-emitting diodes to emit light is a low voltage of 30 volts DC or less. This is because the power source burying work is easy and possible without the need.

  FIG. 2 is a side sectional view taken along line AA in FIG. In the self-luminous road fence 10, the fence main body 1 is embedded flush with the road surface G, and the solar cell 4 is housed in the center of the lower surface of the translucent body 2. The solar cell 4 generates electric power when daytime sunlight rays enter through the translucent body 2, but the solar cell 4 is arranged below the flat portion of the protruding portion 21, so that the sunlight rays are incident from above. Is not lost by the light emitting surface 22 or the like, and power is generated efficiently. The light emitted from the light emitter 3 is refracted by the incident surface 23 provided opposite to the light emitter 3, passes through the translucent body 2, and is further refracted by the light emitting surface 22, so that it can be used by road users. Radiated towards.

  Also, below the solar cell 4, a power storage device 5 that stores electric power generated by the solar cell 4 and discharges it in the evening or at night, and a controller 6 that controls light emission such as blinking and flow blinking of the light emitter 3, etc. are appropriately stored. Electric power is supplied directly from the solar cell 4 or from the power storage device 5 and is appropriately controlled by the controller 6 so that the light emitter 3 is lit or blinked only day or night or at night.

  FIG. 3 is a cross-sectional view showing details of a mechanism in which light is emitted from the light emitter 3 to a road user. The light emitters 3 are arranged inwardly with the optical axis 31 in the horizontal direction at the left and right lower portions of the translucent body 2. A protruding portion 21 having a shape is projected. The inclined side surfaces forming the projections 21 are respectively light emitting surfaces 22, and the light incident surfaces 23 are respectively formed below the light emitting surfaces 22 so as to face the light emitters 3.

  The incident surface 23 is provided so as to be inclined with respect to the optical axis 31 of the light emitter 3, and the light beam L1 of the light emitter 3 emitted in the horizontal direction is the incident surface 23 which is an interface between the light transmitter 2 and air. The light beam L2 is refracted upward and passes through the translucent body 2 as an obliquely upward light beam L2, and is refracted downward by the opposing light emitting surface 22 to be emitted as a light beam L3 having a small elevation angle α. The presence of the self-luminous road fence 10 is urged to the road user, particularly the driver of the vehicle. The refraction angle of the light beam L on the incident surface 23 and the light emitting surface 22 is determined by the refractive index of the material forming the light transmitting body 2, but the inclination angle of the incident surface 23 with respect to the optical axis 31 of the light emitting body 3 is It is necessary to set the light beam L so that it is refracted upward by the incident surface 23 and reaches the light emitting surface 22, and the inclination angle of the light emitting surface 22 is emitted from the light emitting surface 22 at a predetermined elevation angle α. It is appropriately set according to the inclination angle of the light beam L1 when it reaches the light emitting surface 22.

  Further, a part of the light rays or scattered light emitted from the light emitter 3 in a direction other than the incident surface 23 is transmitted through the light transmitter 2 and emitted upward. For example, the light beam L4 emitted obliquely upward from the light emitter 3 is transmitted through the light transmitting body 2 while being slightly refracted, and is emitted from the top surface of the light transmitting body 2 as a light beam L5 having a large elevation angle β. In addition, it is possible to alert road users, particularly pedestrians and bicycles, to the presence of the self-luminous road fence 10 and to inform the change of the light emission mode of the light emitter 3.

  Although the elevation angle α of the light beam L3 emitted from the light emitting surface 22 is not particularly limited, it can be effectively visually recognized substantially in line with the line-of-sight angle when viewed from a vehicle driver 50 m or more away. It is preferable to make it as small as possible, about 1 to 5 degrees. The elevation angle β of the light beam L5 emitted from the upper surface of the translucent body 2 is preferably about 30 to 90 degrees so that nearby pedestrians and bicycles can easily see.

  Further, the light emitter 3 may be disposed with its optical axis 31 obliquely upward, or may be disposed directly above, and the arrangement direction is not particularly limited. Also, the angle of the incident surface 23 with respect to the optical axis 31 of the light emitter 3 is obtained by inclining the incident surface 23 with respect to the optical axis 31 of the light emitter 3 or making it perpendicular to the optical axis 31 of the light emitter 3. Is appropriately set so that the light beam L of the light emitting body 3 incident on the light transmitting body 2 reaches the light emitting surface 22.

  FIG. 4 is a top view showing an example of the flow blinking of the light emitters 3 arranged in a vehicle seat shape. The light-emitting body 3 marked with ○ is emitting light, but one light-emitting body 3 may emit light sequentially as shown in (a), or two lights are emitted as shown in (b). The body 3 may emit light sequentially. Further, two or four opposite to each other may emit light sequentially, and appropriate flow light emission may be performed according to the installation situation and a desired level of attractiveness. In addition to the above-described effect, the flow blinking makes it appear as if the light emission flows due to the afterimage effect, and the light emission area appears to be large, thereby further enhancing the attractiveness.

  FIG. 5 shows a first embodiment according to the present invention, and is an explanatory diagram showing a situation in which the flashing of a self-luminous roadway is performed when the approach of a vehicle is detected. When the vehicle C traveling on the road R enters a sensing region by the detection wave S radiated from the sensing means 20 and the vehicle C is detected, it is self-luminous by a wireless or wired communication means (not shown). The road blinking is instructed to the road fence 10, and the self-light-emitting road fence 10 which has been in a state where some light emitters blink until then starts to blink and changes the light emission mode. A change in the light emission mode is visually recognized by a pedestrian H or a bicycle B passing in the vicinity of the self-luminous road fence 10, and an accident at an intersection or the like can be reduced by predicting the approach of the vehicle.

  In this embodiment, the eaves body 1 and the translucent body 2 are formed as separate bodies, and the eaves body 1 protects the translucent body 2 with strength and makes the installation of the eaves body 1 to the road surface G reliable and easy. However, if possible in terms of strength, the bag main body 1 and the translucent body 2 may be integrally formed using the hard transparent glass, a transparent synthetic resin such as polycarbonate or acrylic resin, or the like.

(Second Embodiment)
FIG. 6A is a cross-sectional view showing a schematic configuration of a second embodiment of the self-luminous road fence according to the present invention, and FIG. 6B is a see-through view of the road fence shown in FIG. It is the schematic plan view which looked at the state which removed the light body from the plane. FIG. 7 is a view showing a state where the road fence is buried in the ground. The materials and materials of the components of the road fence of the second embodiment can be the same as the materials and materials of the corresponding components of the road fence of the first embodiment. Detailed explanation is omitted here.

  As shown in FIGS. 6 and 7, the road fence 100 includes a fence main body 110 embedded in the road surface G, a translucent body 120 placed on the fence main body 110, and a light emitting unit 131 and is energized. A plurality of light emitters 130 (books) arranged side by side along the circumferential direction of the bag main body 110 (in the direction of arrow X in the figure) so that light emitted from the light emitting unit 131 is emitted to the outside through the light transmitting body 120. In the example, 24 light-emitting diodes (LEDs)), sensing means 140 for detecting the approach of an approaching object such as a pedestrian, a bicycle driver, or a vehicle driver, and a power source for energizing the plurality of light emitters 130 A device 150 (see FIG. 11 to be described later) and a control device 160 (see FIG. 11) that controls energization of the plurality of light emitters 130 by instructing the power supply device 150. As shown in FIG. Road filled with adhesive Q Is pushed into the hole G 'of slightly larger ground G than the width of the tack 100 is placed on the ground surface G. At this time, excess adhesive Q pushed out from the gap with the hole G ′ of the ground G around the road fence 100 is wiped off so as not to adhere to the edge of the translucent body 120 of the road fence 100. The road fence 100 thus installed is subjected to a predetermined light emission operation as described later.

  FIG. 8 (A) is a schematic plan view of a state where only the main body 110 is taken out from the road surface 100 shown in FIG. 6, and FIG. 8 (B) is a schematic end view of the main body 110. FIG. 8C shows a schematic bottom view of the bag main body 110 viewed from the bottom.

  As shown in FIG. 8A, the heel body 110 has a circular shape in plan view (as viewed from the plane), and is formed in parallel or substantially parallel to the peripheral edge portion 111 along the circumferential direction X. And a doughnut-shaped planar region 112, which is embedded in the road surface G so that the planar region 112 faces upward and is parallel or substantially parallel to the road surface G. As shown in FIG. 8B, the peripheral end portion 113 of the peripheral edge portion 111 extends upward and has a mortar-shaped concave portion 114 inside the donut-shaped planar region 112. Here, in this example, the material including the flat region 112 of the bag main body 110 employs a metal such as an aluminum alloy die casting whose light reflectance is improved by polishing, and the flat region 112 is polished.

  In addition, as shown in FIG. 8C, the bag main body 110 has blade-like portions 115 extending radially in eight directions from the concave portion 114 'on the bottom surface to the planar region 112' on the bottom surface. When the road fence 100 is pushed into the hole G ′ of the ground G (see FIG. 7) by the blade-like portion 115 (see FIG. 7), the adhesive fence Q is rectified so that the road fence 100 is pushed. Can be suppressed. As shown in FIG. 7, a plurality of recesses 113 a are provided along the circumferential direction X on the outer side of the peripheral end portion 113 of the heel body 110. This recess 113a is not particularly required, but by providing the recess 113a, the effect of suppressing the pushing force of the road fence 100 when the road fence 100 is pushed into the hole G ′ of the ground G can be further improved. . Further, by reducing the thickness of the peripheral end portion 113 to such an extent that there is no problem in strength (so-called meat stealing), it is possible to reduce the weight of the bag main body 110.

  FIG. 9 shows a schematic plan view of the translucent body 120. The translucent body 120 has a circular shape in plan view, and as shown in FIGS. 6A and 9, the position of the light emitter 130 on the upper surface of the translucent body 120 (see a in FIG. 6A). Further outside in the radial direction and a predetermined distance (see c in FIG. 6A) from the edge of the translucent body 120 (see b in FIG. 6A), although not limited thereto, in this example, 12 mm And a light emitting surface 120a formed in a ring shape (see FIG. 9) continuously in a plan view along the circumferential direction X inclined with respect to the optical axis of the light emitter 130. In addition, it is placed so as to cover at least a part of the planar region 112 of the heel body 110 along the circumferential direction X, and is attached to the heel body 110 with an attachment screw 117. A packing 116 for filling the gap is arranged so that dust or the like does not enter the flat area 112 from the gap between the upper surface of the heel body 110 and the lower surface of the translucent body 120. As the packing 116, a general-purpose O (O) ring or the like can be used. At this time, the packing 116 is arranged so as to be on the outer side where dirt such as dust is reduced as much as possible in the planar region 112, and is considered inconspicuous due to light refraction by the inclined light emitting surface region 120a when viewed from the front. The light emitting surface area 120a is disposed immediately below the inclined light emitting surface area 120a.

  FIG. 10 shows a state where the cross-sectional view of FIG. As shown in FIG. 10, the translucent body 120 has an optical axis with respect to the optical axis of the light emitter 130 so that the light from the light emitter 130 can be emitted from the inclined light emitting surface 120a or the like at a position corresponding to the light emitter 130. A light emitter insertion hole 121 having an incident surface 121a that is inclined in the direction is provided. If the thickness of the light transmitting body 120 (see d in FIG. 10) is too thick, the light transmittance is likely to decrease, and if it is too thin, the strength is likely to decrease. Therefore, the strength can be improved while suppressing light transmission loss. Depending on the thickness, for example, the size of the transparent body 120, about 20 mm can be mentioned. In the gap between the peripheral side surface 120b of the translucent body 120 and the inner side surface 113b of the peripheral end portion 113 of the bag main body 110, a caulking 191 for filling the gap is applied. Here, considering that the caulking 191 or the like can be seen due to light refraction when viewed from the front, embossing 122 is performed near the entrance surface 121a of the insertion hole 121 on the upper surface of the translucent body 120. Alternatively, embossing can be further performed on the peripheral side surface 120b of the light transmitting body 120, or a tape 192 of a predetermined color such as black can be attached. In addition, when embossing 122 is performed on the upper surface of the translucent body 120, it is preferable that the region P (see FIGS. 9 and 10) in which a solar cell 151 to be described later is not processed and the light transmittance is maintained. . Further, in order to support the light transmitting body 120, a support column 123 as shown by a broken line in FIG. 10 is provided in the vicinity of the center of the lower surface of the light transmitting body 120, or the strength of the light emitting body insertion hole 121 is further improved. Therefore, the strength is ensured by increasing the rib 121c having a predetermined width (see e in the drawing) as shown by the broken line in FIG. 9 between the portions 121b of the light transmitting body 120 corresponding to the adjacent light emitters 130. The thickness of the body 120 may be further reduced. Further, as shown in FIG. 9, a plurality of protrusions 124 having a predetermined height are provided radially on the upper surface of the light transmitting body 120 (not limited to this, but radially in increments of 7.5 ° in this example). Yes. If the height of the protrusion 124 is too high, there is a possibility that it becomes a starting point of cracking of the translucent body 120. Although not limited thereto, for example, about 0.5 mm is preferable. By doing so, even if it rains and water is applied, water and dust are unlikely to accumulate on the upper surface of the translucent body 120, easily flow toward the outside, and have an advantage as an anti-slip.

  As described above, the light emitter 130 is an LED in this example, and is connected to the control device 160 (see FIG. 11). As shown in FIG. 10, the light emitter 130 is above the position of the planar region 112 of the bag main body 110 (see f in FIG. 10), below the top of the translucent body 120 (see g in FIG. 10), and In this example, radially in the upper direction of the substrate 170 in the radial direction so that the light emitting portion 131 faces outward from the position covering the planar region 112 (see h in FIG. 10) radially inward. The optical axes are arranged in parallel so as to be parallel or substantially parallel to the planar region 112. Since each light emitter 130 is arranged so that the light emitting part 131 faces outward, for example, compared to a case where the light emitting part is arranged so as to face inward as in the road fence of the first embodiment, for example. The optical path distance between the incident surface 121a of the insertion hole 121 and the inclined light emitting surface 120a can be shortened, and the light transmission loss can be suppressed accordingly. Further, since the inclined light emitting surface 120a is formed radially inward from the edge 120b of the transparent body 120 at a predetermined distance c (see FIG. 6A), the incident surface 121a and the inclined light emitting surface 120a are formed. The optical path distance can be further shortened, light transmission loss can be further suppressed, and the optical path distance between the incident surface 121a and the inclined light emitting surface 120a is relatively short, so the light from the incident surface 121a and the inclined light emitting surface The light from 120a appears to be emitted at approximately one point, and the visibility as the flow flashing can be improved.

  The direction of the optical axis of each light emitting body 130 is not limited to the direction parallel or substantially parallel to the plane region 112, and may be obliquely upward or diagonally downward depending on the situation, from leaking light to the outside, the planar region 112, or the like. Visibility can be improved by adjusting the amount of reflected light. Each light emitter 130 is supported by a holder 132, and the light emitting portion 131 protrudes outward from the holder 132. Thereby, compared with the case where the light emission part 131 does not protrude from the holder 132, the light which goes below the light emission part 131 is not blocked by the holder 132, Therefore The light quantity of the light which goes below the light emission part 131 can be increased. . In the road fence 100 having such a configuration, the first light L6 can be emitted from the light emitting unit 131 of the light emitting body 130 through the light transmitting body 120 to the outside via the inclined light emitting surface 120a. The second light L7 is emitted from the light emitting unit 131 through the translucent body 120, reflected to the planar area 112 of the bag main body 110, and through the vicinity of the peripheral area of the translucent body 120 (see the broken line k in FIG. 10). can do. At this time, the inclined light emitting surface 120a from which the first light L6 can be emitted is formed radially inward from the end edge 120b of the translucent body 120 at a predetermined distance c, and thus the end edge 120b of the translucent body 120 is formed. The second light L7 can be emitted at a predetermined distance c. The elevation angle α ′ of the light beam of the first light L6 emitted from the inclined light emitting surface 120a of the translucent body 120 is effectively visually recognized substantially coincident with the line-of-sight angle when viewed from a vehicle driver mainly 50 m or more away. As can be seen, in this example, it is as small as 1 to 5 degrees. In addition, the elevation angle β ′ of the light beam of the second light L7 emitted from the vicinity of the peripheral region k of the translucent body 120 is mainly set so that it can be easily visually recognized by road users such as nearby pedestrians and bicycle drivers. Then, it is about 15 to 90 degrees.

  In this example, the sensing means 140 is a phototransistor that receives light such as an approaching object such as a vehicle or a bicycle with a headlight turned on when the surroundings are dark such as evening or night, and the control device 160 (see FIG. 11), and as shown in FIG. 6 (B), every other two light emitters 130 are arranged in parallel along the circumferential direction X. By doing so, the detection range in the circumferential direction X of the road user can be widened. In this example, in the case of a vehicle, the detection sensitivity of the phototransistor is about 30 m to 40 m for the headlight and about 100 m for the high beam. Note that the phototransistor 140 here can also detect ambient brightness. Moreover, the sensing means 140 may use a pyroelectric sensor that receives the infrared rays of an approaching object that emits infrared rays, such as a pedestrian, a bicycle driver, or a vehicle, and detects the approaching of the approaching object.

  FIG. 11 shows a schematic block diagram of the control system of the road fence 100. As shown in FIG. 11, the power supply device 150 is connected to the control device 160 and energizes the light emitter 130 under the instruction of the control device 160. Further, in this example, the power supply device 150 includes a solar cell 151, a storage battery 152, and a booster 153. Only when the generated power of the solar cell 151 exceeds a predetermined amount, the power supply device 150 changes from the solar cell 151 to the storage battery 152. It is comprised so that electric power can be supplied. The electric power supplied from the storage battery 152 is sent to the control device 160 via the booster 153.

  As shown in FIG. 10, the solar cell 151 is provided at a lower portion of the circular central region P in the radial direction of the light transmitting body 120 via the battery support 171 on the upper side of the substrate 170. Corresponding to this circular central region, as shown in FIG. 6 (B), five long first cells 151a each having the same area are arranged side by side, and outside the first cell 151a. A second cell 151b, which is shorter than the cell 151a but is wider and has the same area as the cell 151a, is disposed. That is, the solar cell 151 is configured by arranging seven cells 151 a and 151 b below the translucent body 120. Note that the number of cells, voltage, area, current, etc. are appropriately determined to prevent a small cell from becoming rate-limiting. In addition, the storage battery 152, the booster 153, and other electrical components are disposed on the lower side of the substrate 170, but are not illustrated in FIGS. 6A and 10. Of course, the road fence 100 using such a power supply device 150 may be lit during the day (24 hours) regardless of day or night, but the power generation capacity of the solar cell 151 and the storage battery 152 Considering the charging capacity, it is preferable that the light emitting operation is performed only when the surroundings are dark, such as in the evening or at night. The road fence 100 of this example is configured to perform a light emitting operation when the power generation voltage of the solar battery 151 becomes a predetermined threshold value or less.

  As described above, the control device 160 illustrated in FIG. 11 is connected to the power supply device 150, the LED 130, and the phototransistor 140, and is provided on the substrate 170. The control device 160 includes a control unit 161 including a storage unit such as a RAM and a ROM that records a control program, and a control unit such as a microprocessor chip that executes the control program, and a resistor 162 corresponding to each of the light emitters 130. When the program is executed by a control unit such as a microprocessor chip, as shown in FIG. 6B, the program is composed of one of the plurality of light emitters 130 or two or more adjacent light emitters. 8 groups of light emitter groups 130a, 130b,..., 130h composed of three adjacent light emitters 130 out of 24 light emitters 130 in this example. 130a (illuminant group 130a in the illustrated example) is replaced with an adjacent light emitter group (illuminant group 130b in the illustrated example). The light emitters 130a, 130b,..., 130h are energized so that the light emitter groups 130a, 130b,..., 130h flow and blink one by one sequentially in the circumferential direction X (X1 in the illustrated example). Is to control. In this example, the number of light emitter groups is eight, and is preferably a multiple of eight. Normally, the data structure of a digital electronic component is basically 8 bits, and by using a multiple of 8 in this way, the versatility of the digital electronic component that can be employed in the control device can be enhanced.

  In this example, when the approach of the approaching object is not detected by the sensing means 140, the control device 160 detects the approach of the approaching object by the sensing means 140 so that the first light emission mode in which the light emission of a predetermined condition is performed. When the light emitting element is turned on, the light emitting body emits light under a condition different from that of the first light emitting mode and is at least in the second light emitting mode in which the flow blinks, and returns to the first light emitting mode after a predetermined time has elapsed. 130 energization is controlled. The predetermined time from the start of the second light emission mode to the return to the first light emission mode is not limited to this, but is about 10 to 30 seconds here.

  More specifically, in the first light emission mode, light emission of a predetermined first period (for example, light emission including simultaneous blinking and the flow blinking) is performed, and in the second light emission mode, a second speed that is faster than the first period. Periodic light emission (e.g., light emission including simultaneous blinking, flow blinking, etc.) and at least the flow blinking is performed. At this time, the luminance in the second light emission mode may be greater than the luminance in the first light emission mode. In this case, the power supplied to the light emitters 130 in the light emitter groups 130a to 130h may be changed, and / or since there are a plurality of light emitters 130 in the light emitter groups 130a to 130h, the light emitters 130 are caused to emit light. You may change the number of times.

  FIG. 12A shows a timing chart in which each of the light emitter groups 130a to 130h during the first period flashes, and FIG. 12B shows each of the light emitter groups 130a to 130h during the second period. Shows a timing chart in which the flow blinks. Here, the first period T1 is about 480 msec / time, and the second period T2 is about 160 msec / time, which is about 1/3 of the first period T1. Further, the lighting time V of each of the light emitter groups 130a to 130h is about 60 msec (first period / number of groups) at the first period T1 and about 20 msec (second period / number of groups) at the second period T2. The turn-off time W is about 420 msec (first period-lighting time) in the first period and about 140 msec (second period-lighting time) in the second period.

  At this time, as shown in FIG. 13, depending on the road conditions in the direction in which light is emitted in the luminous body groups 130a to 130h (in the illustrated example, one is a wide road when provided at the intersection of four roads, the other Depending on the narrow road), the brightness of the corresponding luminous body group may be changed. In this case, in order to make the second luminance brighter than the first luminance, for example, the power supplied to the light emitters 130 in the light emitter groups 130a to 130h may be changed, and / or the light emitter group 130a. Since there are a plurality of light emitters 130 in ~ 130h, the number of light emitters 130 that emit light may be changed. In FIG. 13, the luminance of the corresponding light emitter group is changed so that the luminance is high for a narrow road and weak for a wide road. Further, as shown in FIG. 14 (A), the color scheme of the corresponding luminous body group may be changed according to a wide road on one side and a narrow road on the other side when provided at the intersection of four roads, As shown in FIG. 14B, the luminance and color scheme of the corresponding luminous body group may be changed according to the main road, the sub road, and the narrow road when provided at the intersection of 6 roads. Alternatively, as shown in FIG. 14C, the color scheme of the luminous body group may be changed regardless of the road conditions. In FIG. 14A, the color scheme of the corresponding luminous body group is changed so that red light is emitted on narrow roads and yellow light is emitted on wide roads. In FIG. 14B, the luminance is higher than the luminance of the sub-road for a narrow road so that yellow light is emitted for the main road and red light is emitted for the sub-road. The luminance and color scheme of the corresponding light emitter group are changed so that the red light of the corresponding light is emitted. In FIG. 14C, the color scheme of the luminous body group is changed so that red, orange, yellow, green, blue, indigo, purple, and white light are emitted in this order along the circumferential direction X. . In any case, when simultaneous flashing is performed, only the luminous body group corresponding to the direction on the road may be flashed. In addition, as shown by a broken line in FIG. 11, the control device 160 prepares other parts as common parts in advance by controlling the control unit 161 and the resistor 162, and controls at the time of ordering. A control program corresponding to the order of the unit 161 is stored in a storage means such as a RAM or a ROM, and the control unit 161 and the resistor are attached to other parts prepared as common parts and assembled. Can do. Thereby, shortening of the delivery time from order to shipment can be realized.

  In the self-luminous road fence 100 described above, the fence body 110 has a planar area 112 formed in parallel or substantially parallel to the peripheral edge portion 111 along the circumferential direction X so that the planar area 112 faces upward. And embedded in the road surface G so as to be parallel or substantially parallel to the road surface G, the translucent body 120 is radially outward from the position of the light emitter 130 on the upper surface of the translucent body 120, and The inclined light emitting surface 120a continuously formed along the circumferential direction X inclined with respect to the optical axis of the light emitter 120 at a predetermined distance c from the edge 120b of the light transmitter 120 and radially inward. And a part of the planar area 112 of the heel body 110 is placed so as to cover the circumferential direction X, and the light emitter 130 is transparent above the position f of the planar area 112 of the heel body 110. Below the top g of the light body 120 and in a plane Since the light-emitting portions 131 are arranged in parallel along the circumferential direction X so as to face outwardly from the position h covering the region 112 in the radial direction, the light-emitting portions 131 of the light-emitting body 130 are exposed to the outside via the inclined light-emitting surface 120a. The first light L6 can be emitted, is reflected from the light emitting part 131 of the light emitter 130 to the planar region 112 of the bag main body 110, and the second light L7 is emitted to the outside through the upper surface portion k of the translucent body 120. Can be released. Furthermore, since the planar region 112 is polished, the light reflectance of the planar region 112 is improved, and the amount of light of the second light L7 can be increased. At this time, the inclined light emitting surface 120a from which the first light L6 can be emitted is formed radially inward from the end edge 120b of the translucent body 120 at a predetermined distance c. The second light L7 can be emitted at a predetermined distance c from 120b.

  The figure for demonstrating the light emission operation | movement of the self-light-emitting road fence 100 installed in FIG. 15 at the intersection of a 5-way difference is shown. According to the self-luminous road fence 100 installed in this way, the light emitters 130 are juxtaposed along the circumferential direction X even if the direction of the optical axis of the light emitters 130 is not strictly defined at the time of installation. The light emitter 130 can radiate light rays L6 and L7 toward road users such as the vehicle driver M and the pedestrian N to emphasize the presence of the road fence 100. By flashing, it is possible to obtain a higher attractiveness than when the light emitter 130 simply flashes, and it has excellent visibility not only to the vehicle driver M but also to the pedestrian N, etc. The power can be improved.

  In addition, since there are three light emitters for each of the eight light emitter groups 130a to 130h on the roadside 100, and light is emitted in 24 directions, for example, not only the usual four difference paths but also 3 It can be suitably used for any intersection such as a difference road or an intersection of five or more differences. Further, in this example, the light emitting operation is performed when the surroundings become dark and the voltage of the solar cell 151 becomes a predetermined threshold value or less. Since the phototransistor 140 for detection is provided, the control device 160 changes the light emission mode when the vehicle M is approaching and when it is not, and more specifically, the phototransistor 140 causes the light of the headlamp of the vehicle M to be changed. When ML is not detected, the second light emission mode is entered when the light ML of the headlamp of the vehicle M is detected by the phototransistor 140 so that the first light emission mode is entered. By controlling the energization of the light emitter 130 so as to return to the first light emission mode after the lapse of time, the attractiveness can be further enhanced by the difference in the light emission mode, and the vehicle M It is possible to notice the approach of the vehicle M light emitting mode such as a pedestrian N and bicycle rider to passing around by changes with the near, it is possible to preferably obtain a higher alert effect.

  In addition, in this example, since the shape seen from the plane of the main body 110, the translucent body 120, the inclined light emitting surface 120a of the translucent body 120, and the central region lower part P are all circular, the light rotates. It is possible to enhance the image as a self-illuminating roadway that performs the above-described flow blinking. Moreover, since the shape seen from the plane of the planar area 112 of the main body 110 is a donut shape, a lathe or the like can be used to polish the planar area 112 from which light is reflected. Therefore, the work quality of the polishing process can be improved.
