Design Registration No. 1460558

The indicator lamp disclosed in Patent Document 1 attempts to improve visibility by arranging a large number of light emitting diodes at equal intervals to illuminate an annular light emitting display portion. In order to improve the visibility of conventional display lamps including those disclosed in Patent Document 1, the main purpose is to increase the number of light emitting diodes to increase the brightness (luminance) of the light emitting display section.
However, in the case where the light-emitting display portion is a thin annular shape like the indicator lamp described in Patent Document 1, visibility is not always improved only by increasing the luminance. In addition, since a large number of terminals are connected to a fire fighting facility, the current that can be used is limited, and it is difficult to increase the current flowing through the facility. Because of such restrictions, even if the number of light emitting diodes of the indicator lamp is increased, only the brightness of each LED is reduced, and the visibility is not improved.

  The present invention has been made to solve such a problem, and in the case where the light emitting display portion is annular, it is possible to obtain an indicator lamp capable of improving the visibility without increasing the number of light sources or the luminance. It is an object.

[Embodiment 1]
In the present embodiment, an indicator lamp 1 that is attached to a wall surface 5 such as a housing of a fire hydrant facility as an attachment surface and that houses a transmitter 3 (see FIGS. 6 and 7) is taken as an example.
In the following, first, each configuration of the indicator lamp 1 will be described in detail based on FIGS. 1 to 5 with reference to other drawings as appropriate, and then the transmitter 3 housed in the indicator lamp 1 will be described.
In the following description, the front side of the wall surface 5 is referred to as the front while the indicator lamp 1 is attached to the wall surface 5, and the back side of the wall surface 5 is referred to as the back and back.

〔Indicator light〕
As shown in FIG. 1, the indicator lamp 1 includes an outer peripheral wall portion 7 made of a substantially cylindrical body, a mounting portion 9 made of a flange projecting outward from an outer peripheral surface on the front end side of the outer peripheral wall portion 7, and an outer peripheral wall The light emitting display unit 11 is formed in a ring shape on the inner side of the front end side of the unit 7, and the transmitter housing unit 13 is formed on the inner side of the outer peripheral wall 7 continuously to the light emitting display unit 11.
As shown in FIG. 3, a space portion 14 is formed between the outer peripheral wall portion 7 and the peripheral walls of the light emitting display portion 11 and the transmitter housing portion 13 formed inside thereof, and the space portion 14 emits light. A substrate 17 on which the element 15 is mounted is installed.
In addition, the outer peripheral wall portion 7, the light emitting display portion 11, and the transmitter housing portion 13 in the present embodiment correspond to the main body portion of the present invention, but conversely, the main body portion of the present invention does not have to include all of these, Any shape can be used as long as it has a function of accommodating a light emitting source.

<Outer peripheral wall>
The outer peripheral wall portion 7 is formed in a substantially short cylindrical shape by a translucent resin member.

<Mounting part>
The attachment portion 9 is for attaching the indicator lamp 1 to the wall surface 5 and is formed in a substantially square flange shape projecting outward from the outer peripheral surface on the front end side of the outer peripheral wall portion 7 as described above.
As shown in FIGS. 1 and 2, screw holes 9 a for attaching the indicator lamp 1 to the wall surface 5 are provided at the four corners of the attachment portion 9.
The attachment portion 9 is provided with a ring-shaped standing piece portion 9 b that borders the outer periphery of the light emitting display portion 11. That is, the ring-shaped standing piece 9b is provided on the outer peripheral edge of the ring-shaped inclined surface which is the light-emitting display unit 11. When the indicator lamp 1 is attached to the wall surface 5, the upright piece portion 9 b abuts against the edge of the opening provided in the wall surface 5 from the inside (see FIG. 3) to position (align) the indicator lamp 1. It has a function to do.

<Light emission display>
As shown in FIGS. 1 to 3, the light emitting display portion 11 is formed in a ring shape that is inclined from the inner peripheral edge of the mounting portion 9 toward the inner side and toward the inner side. In FIG. 2, the light-emitting display unit 11 is colored to clearly show it.
As shown in FIG. 3, the light-emitting display unit 11 does not protrude beyond the wall surface 5 in the installed state of the indicator lamp 1, and from the side like a conventional general bulge-type indicator lamp. Will not be damaged by bumping.
The light-emitting display unit 11 is made of, for example, a red light-transmitting member, and transmits light from the light-emitting element 15 (see FIG. 3) accommodated in the space 14 so as to shine brightly. The arrangement relationship between the light emitting display unit 11 and the light emitting element 15 will be described later.

<Transmitter housing>
As shown in FIGS. 1 and 3, the transmitter accommodating portion 13 is formed in a step shape from the inner periphery to the inner side and the rear side of the light emitting display portion 11, and the bottom of the step is a transmitter for attaching the transmitter 3. It is a machine mounting surface portion 21 (see FIGS. 1 and 2).

The transmitter mounting surface portion 21 is formed of a light-transmitting member and has a flat surface with an opening at the center, and screw holes 21a for mounting the transmitter 3 are provided on both sides.
A reflector 25 is attached to the transmitter mounting surface portion 21 so as to cover the entire surface of the transmitter mounting surface portion 21. By attaching the reflection plate 25, the light of the light emitting element 15 is reflected by the reflection plate 25, further diffusely reflected by the surface of the substrate 17, and emitted as indirect light from the light emitting display unit 11 to the outside. Thus, by attaching the reflecting plate 25, the light-emitting display unit 11 can be illuminated with indirect light, and the light-emitting display unit 11 can be illuminated brightly as a whole.

This point will be described with reference to FIGS. 4 and 5 with examples. 4 shows a state in which the light emitting element 15 emits light without attaching the reflecting plate 25, and FIG. 5 shows a state in which the reflecting plate 25 is attached to the one shown in FIG. In FIG. 4, a portion where the light emitting element 15 is present is displayed in white.
As shown in FIG. 4, since the light emitting element 15 is disposed on the back side of the transmitter mounting surface portion 21, the light from the light emitting element 15 is reflected when the reflector 25 is not attached to the transmitter mounting surface portion 21. Without transmitting, it does not contribute to transmitting the light emitting display portion 11 through the transmitter mounting surface portion 21.
On the other hand, when the reflecting plate 25 is attached, as shown in FIG. 5, the light reflected by the reflecting plate 25 enters the light emitting display unit 11 as indirect light, and the light emitting display unit 11 shines brightly as a whole. Visibility is improved. Thereby, even if the number of the light emitting elements 15 is small, necessary visibility is ensured, and thus a power saving effect is also obtained.

<Board>
As shown in FIG. 1, the substrate 17 is formed by a disc having an opening at the center, and a plurality of light emitting elements 15 as light emitting sources are arranged on the front side of the substrate 17.
As shown in FIG. 3, the substrate 17 is attached so that the front side faces the transmitter attachment surface portion 21.
By attaching the substrate 17 in this manner, the light emitting element 15 is disposed so as to face the transmitter attachment surface portion 21 in the space portion 14 (see FIG. 2).

FIG. 2 is a front view of the indicator lamp 1 with the substrate 17 attached, and the light emitting elements 15 on the substrate 17 are indicated by broken lines.
The light-emitting elements 15 are arranged so that the light-emitting elements 15 closest to the left and right ends of the substrate 17 are closest to the light-emitting display unit 11 than the other light-emitting elements 15 (see FIG. 2). ). In the example of FIG. 2, a part of the light emitting elements 15 at both the left and right ends is arranged so as to cover the light emitting display unit 11 in a front view.
By arranging the light emitting element 15 in this way, both side portions of the light emitting display portion 11 shine brighter than the upper and lower portions. And since the brightness difference is made between both side parts and the upper and lower parts, the visibility is enhanced as compared with the case where the light emitting display part is lit with uniform brightness.
In addition, making both side parts of the light-emitting display unit 11 shine brighter than the upper and lower parts means that both side parts are relatively brighter than the upper and lower parts, and that both side parts are absolutely bright. Not what you want. Moreover, both side parts are the concepts for distinguishing from the upper and lower parts, and an area | region is not specified exactly | strictly.

The transmitter 3 is provided at a certain height (80 to 150 cm from the floor), and the indicator lamp 1 provided integrally with the transmitter 3 is also provided at the same height. That is, the indicator lamp 1 is provided at a position close to the human eye. When the indicator lamp 1 is viewed from the vicinity of the wall where the indicator lamp 1 installed at such a height is installed, that is, at a shallow angle, the light emitting display unit 11 does not see the front side, but the back side. Is always visible (see FIG. 7). Accordingly, by brightly illuminating both sides of the light-emitting display unit 11, the display lamp 1 can be securely viewed even when the display lamp 1 is viewed obliquely along the wall surface 5 with the display lamp 1 attached to the wall surface 5. It has the effect of being visible.
In addition, since both sides of the light-emitting display unit 11 shine brightly, the upper and lower sides of the light-emitting display unit 11 become relatively dark, and a change occurs in the way the light-emitting display unit 11 shines. This also improves visibility. doing.

[Transmitter]
Next, the transmitter 3 accommodated in the transmitter accommodating portion 13 of the indicator lamp 1 described above will be described below with reference to FIGS. 6 and 7.
As shown in FIG. 6, the transmitter 3 includes a push button 31 that emits a fire signal when pressed, a disk-shaped push button storage portion 33, and a transmission formed on the back side of the push button storage portion 33. And a machine body 35.

The push button storage portion 33 is provided with a telephone jack window door 33a that is provided inside the push button storage portion 33 and covers a telephone jack (not shown) to which a handset is connected so as to be freely opened and closed.
The transmitter body 35 has a box shape and stores therein a switch or the like (not shown) linked to the push button 31.

  As shown in FIG. 7, when the transmitter 3 is accommodated in the transmitter accommodating portion 13 of the indicator lamp 1, it is surrounded by the light emitting display portion 11 and is substantially flush with the inner peripheral edge of the light emitting display portion 11. It is arranged to become. In this state, the position of the transmitter 3 is displayed when the light emitting display portion 11 of the indicator lamp 1 shines.

The effect in the use state (state which accommodated the transmitter 3 and made the light emission display part 11 shine) of the indicator lamp 1 comprised as mentioned above is demonstrated based on FIG.
As shown in FIG. 8, the light emission display unit 11 of the indicator lamp 1 is brightly lit in a normal state and displays the position of the transmitter 3 (disaster prevention device).

  As described above, since both side portions of the light-emitting display unit 11 shine brighter than the upper and lower portions, the display lamp 1 can be reliably recognized even when the display lamp 1 is viewed obliquely along the wall surface 5. Further, since both sides of the light-emitting display unit 11 are brighter than the upper and lower sides, and there is a change in the way the ring-shaped light-emitting display unit 11 shines, Changes the angle at which the indicator lamp 1 is viewed, and accordingly, the areas of both sides and the top and bottom surfaces of the light-emitting display unit 11 that can be visually recognized change. Thereby, the appearance of the indicator lamp 1 is changed, and the visibility is further increased.

Moreover, since the light emission display part 11 becomes the inclined surface which goes to a center part, while being excellent in the visibility from a front side as shown in FIG. 2, it is excellent also in the visibility from a side as shown in FIG. ing.
Further, in this example, the transmitter 3 is installed in the ring of the ring-shaped light-emitting display unit 11 and has the inclined surface as described above. Even in a dark place, it is easy to operate the transmitter 3 and to connect the handset to the telephone jack.
In addition, the indicator lamp 1 does not have a portion that protrudes greatly from the wall surface 5, and an object does not collide with it from the side and is not damaged like the conventional general bulge-type indicator lamp 1.

In the above description, the example in which the light emitting element 15 is arranged toward the front of the indicator lamp 1 as shown in FIG. 3 is shown, but the arrangement of the light emitting element 15 is not limited to this. For example, as shown in FIG. 9, the light emitting element 15 may be arranged toward the center of the indicator lamp 1, and by arranging in this way, the visibility of the indicator lamp 1 from the side can be increased. In FIG. 9, the same components as those in FIG. 3 are denoted by the same reference numerals.
Or the arrangement | positioning which the part which arrange | positions the light emitting element 15 toward the front side, and the part which arrange | positions toward the center of the indicator lamp 1 may be mixed may be sufficient. In any case, however, the light emitting elements 15 arranged on both sides are arranged so as to be closest to the light emitting display portion 11 than the other light emitting elements 15 as in the case shown in FIG.

Further, in the above description, in order to make both sides of the light emitting display unit 11 shine brighter than the upper and lower sides, the light emitting elements 15 arranged on both sides are closer to the light emitting display unit 11 than the other light emitting elements 15. Although the example of arrangement was shown, as another method for making both sides of the light emitting display unit 11 shine brighter than the upper and lower sides, for example, the distance to the light emitting display unit 11 of each light emitting element 15 is made equal, The luminance of the light emitting element 15 may be set higher than that of the upper and lower parts. Or you may adjust both arrangement | positioning of a light emitting element 15, and a brightness | luminance.
Further, the upper and lower portions of the light emitting display unit 11 may be relatively darkened by not arranging the light emitting elements 15 above and below.
Moreover, you may stick a reflecting material on the outer peripheral surface of the outer peripheral wall part 7 so that light may be reflected to the inner peripheral side. By doing so, the light emitted from the light emitting element 15 or the light reflected by the reflecting material does not pass through the outer peripheral wall portion 7 and escape to the back side of the wall surface 5, and the light emitting display portion 11 can emit light efficiently. be able to.
In addition, by attaching a reflective material to the upper and lower surfaces of the light emitting display unit 11, the light from the light emitting element 15 that has been directed toward the upper and lower surfaces can be diffusely reflected, and the upper and lower surfaces can be made to illuminate without causing the upper and lower surfaces to shine. .

  Moreover, although the example of the circular ring was shown as the light emission display part 11, the light emission display part 11 of this invention should just be a ring shape, and is not restricted to a circular ring, For example, a rectangular ring shape may be sufficient, or a polygonal shape. It may be ring-shaped.

  The translucent member which comprises the light emission display part 11 is not restricted to red. The light emitting display part 11 may be comprised with a colorless and transparent translucent member. In this case, when the light emitting element 15 is a red LED, the light emitting display unit 11 is displayed in red.

In the above description, an example is shown in which the transmitter 3 is provided by providing the transmitter housing 13 inside the ring of the light emitting display 11. However, the transmitter 3 is provided outside the indicator lamp 1. May be. In this case, a red disk that covers the inside of the ring of the light emitting display unit 11 may be provided inside the ring of the light emitting display unit 11 instead of the transmitter 3.
Thus, the indicator lamp of the present invention can be configured as an indicator lamp 1 integrated with the transmitter 3, or can be configured as an indicator lamp separate from the transmitter 3, depending on the situation. Can be selected as appropriate.

[Embodiment 2]
10-12 is explanatory drawing of the indicator lamp 37 of Embodiment 2 of this invention, and the same code | symbol is attached | subjected to the same part as Embodiment 1. FIG.
As in the first embodiment, the indicator lamp 37 according to the present embodiment transmits a light emitted from the light source by a main body 39 that houses the substrate 43 on which the light emitting element 15 as a light source is mounted. The light-emitting display unit 11 is formed in a ring shape, and is surrounded by the ring-shaped light-emitting display unit 11 (on the inner peripheral side of the light-emitting display unit 11 in a front view). A transmitter 3 is arranged.

And the board | substrate installation part 41 is provided in both the side parts (both side parts of the main-body part 39) of the light emission display part 11, and the rectangular-shaped board | substrate 43 which mounted the light emitting element 15 in the board | substrate installation part 41 is installed.
As shown in FIG. 10, four light emitting elements 15 are mounted on each substrate 43 linearly in the longitudinal direction of the substrate 43. The substrate installation portion 41 has substrate insertion grooves 41a above and below both side portions of the main body 39, and the substrate 43 is installed by inserting the substrate 43 into the substrate insertion groove 41a.
By installing the substrate 43 as described above, as a result, the light emitting element 15 is arranged on the virtual straight line 45 extending in the vertical direction of the substrate installation portion 41 (vertical direction in the installed state of the indicator lamp 37). (See FIG. 11).

  In addition, in the installation state of the board | substrate 43, the light emitting element 15 is arrange | positioned so that it may light-emit toward the radial inside of the ring-shaped light emission display part 11, as shown in FIG.

In the indicator lamp 37 of the present invention, since the light emitting elements 15 are arranged only on both side portions of the light emitting display portion 11, both side portions shine brighter than the upper and lower portions, and the indicator lamp 37 is viewed obliquely along the wall surface 5. Even when viewed, the indicator lamp 37 can be visually recognized with certainty.
Further, since the light emitting elements 15 are arranged on the imaginary straight line 45, the both side portions of the light emitting display portion 11 are closest to the light emitting elements 15 and the distance from the light emitting elements 15 as the distance from both side portions of the light emitting display portion 11 increases. Is configured to leave. Strictly speaking, the part of the light emitting display unit 11 that is closest to the light emitting element 15 is a part that intersects with a horizontal line drawn from the center of the light emitting display unit 11. As a result, both side portions of the light emitting display portion 11 shine brighter than the upper and lower portions, and the way the ring-shaped light emitting display portion 11 shines changes in the circumferential direction of the ring. By changing the position of the line of sight, the appearance of the indicator lamp 37 is changed, and the visibility is further improved.
Further, since the light emitting element 15 emits light in the radial direction of the ring, the light is directly incident on both side portions of the light emitting display unit 11 and shines brighter. For this reason, the difference in brightness between the side portions and the upper and lower portions is further increased, and the effect of improving the visibility by the above-described action is further increased.

In the above example, four light emitting elements 15 are mounted on each substrate 43. However, the number of light emitting elements 15 is not particularly limited, and one light emitting element 15 is mounted on each substrate 43. Including the case.
Further, although the plurality of light emitting elements 15 provided on each substrate 43 have been described as having the same luminance, the light emitting elements 15 having the same luminance may not be used. For example, by making the light-emitting element 15 provided near the center of each substrate 43 relatively brighter than the light-emitting elements 15 provided near both ends, both side portions of the light-emitting display unit 11 shine brighter. Visibility can be improved.

As shown in FIG. 12, the front surface portion of the transmitter 3 is located on the back side of the light emitting display portion 11, and is located on the front side of the transmitter 3 when the light emitting element 15 is turned on. Since a certain light emitting display unit 11 shines, the light emitting display unit 11 can be visually recognized without being blocked by the transmitter 3 even when the indicator lamp 37 is viewed from an oblique direction, and the light emitting display unit 11 can be reliably viewed.
Further, when the indicator lamp 37 is viewed obliquely in a state where it is installed on the wall surface 5, the light emitting display unit 11 on the side opposite to the side where the viewer is present can be visually recognized. In this regard, in Patent Document 1 (Design Registration No. 1460558), since the front surface of the transmitter disposed inside the annular shape protrudes from the annular indicator light main body, only the side surface on the side where the viewer is present. The way you see is different.

In addition, the light emission display part 11 is good also as a hanging surface which hangs down toward the back | inner side of a ring instead of an inclined surface like Embodiment 1. FIG.
Even when the light emitting display unit 11 is not a sloping lower surface, the depth of the lower surface is set to be deeper than the thickness of the push button storage portion 33 of the transmitter 3 in a state where the transmitter 3 is housed. Thus, the front surface of the push button storage portion 33 of the transmitter 3 is disposed on the back side of the light emitting display portion 11, and the upper portion of the hanging surface (front side in the installed state) is exposed. For this reason, when the light emitting element 15 is turned on, the vertical surface shines, and when the indicator lamp 37 is viewed from an oblique direction, the light emitting display unit 11 can be visually recognized without being obstructed by the transmitter 3, and the light emitting display unit 11 is securely connected. It can be visually recognized.
In addition, since the light emitting display unit 11 is a hanging surface that hangs down to the back side, the ring-shaped light emitting display unit 11 does not spread outward in the ring radial direction, and there is an effect that the overall shape can be made compact.
The ring-shaped light emitting display unit 11 in the second embodiment is not limited to a circular ring as in the first embodiment, and may be, for example, a rectangular ring shape or a polygonal ring shape. .

As described in the first embodiment, for example, a reflecting material is attached to the outer peripheral surface of the outer peripheral wall 7 (see FIGS. 10 and 11) to make the outer peripheral wall 7 opaque, so that The light may be reflected. Thereby, the light emitted from the light emitting element 15 does not pass through the outer peripheral wall portion 7 and escape to the back side of the wall surface 5, and the light emitting display portion 11 can emit light efficiently.
In addition, as a means to make the outer peripheral wall part 7 opaque, the outer peripheral wall part 7 may be covered with a light-transmitting cover body in addition to attaching a reflective material.

  In the second embodiment, it has been described that the substrates 43 are provided on both side portions of the light-emitting display unit 11, but in addition, a substrate including light-emitting elements may be provided on the upper and lower portions of the light-emitting display unit 11. . In that case, by reducing the number of light-emitting elements provided on the upper and lower substrates from the number of light-emitting elements 15 provided on the substrates 43 on both sides of the light-emitting display unit 11, both side portions are more than the upper and lower portions. Can also emit light brightly and change the way it shines in the circumferential direction.
