Description

The present invention relates to an indicator light device that emits light so as to indicate the position of a transmitter that is installed on the wall surface of a building or the like and that notifies of a fire.

A building or the like is provided with an indicator light device that emits light so as to indicate the position of a transmitter that reports a fire. The indicator light device is provided integrally with or in the vicinity of the transmitter on the wall surface of a building, a fire hydrant box installed on the wall surface, or the like. The indicator lamp of the indicator lamp device is normally lit so that the position of the transmitter can be confirmed from the surroundings.

The indicator lamp provided in the indicator lamp device must be visible not only from the front but also from the side. For this reason, the indicator lamp provided in the conventional indicator lamp device has a shape that protrudes from the surface on which it is installed, for example, has a hemispherical shape.

A protruding indicator light may be damaged by a side collision with a person or object. In addition, the indicator lamp is conspicuous in red, and if such an indicator lamp protrudes from the installation surface, it may be felt that the design of the interior of the building is spoiled. Therefore, there has been a demand for an indicator light device that does not protrude from the installation surface and is visible from the side.

For this reason, the applicant of the present application, as shown in Patent Document 1, has an inclined surface-shaped optical display unit arranged so as not to protrude from the front surface of the housing to the indoor side, and generates light directed toward the optical display unit. The light display section is formed to have an inclined surface extending from the back side to the front side of the housing along the direction in which the light from the light emission section travels toward the light display section. Invented a display lamp device formed by a reflecting surface that reflects the light of the room toward the interior.

Japanese Patent Application No. 2015-210327

In the indicator lamp device as disclosed in Patent Document 1, the light-emitting portion is a point light source such as an LED, while the light display portion is planar. The light from the light-emitting portion spreads in the traveling direction, but if the distance between the light-emitting portion and the optical display portion is short, the light does not spread sufficiently, causing light unevenness in the optical display portion. The more uniform the light from the optical display section, the better the visibility and the better the design.

For this reason, in Patent Document 1, the light emitting portion is directed to the opposite side of the optical display portion in the radial direction, and a light reflecting portion is provided at a position facing the light emitting portion of the housing so that the light from the light emitting portion passes through the light reflecting portion. The path of the light is lengthened by allowing the light to travel to the display section. As a result, the light spreads before it reaches the optical display section, so that the unevenness of the light can be reduced.

The length of the light path is determined by the distance between the light emitting portion and the light reflecting portion and the distance between the light reflecting portion and the optical display portion. Since the size of the housing is fixed, the positional relationship of these cannot be changed very much. For this reason, it is difficult to spread the light even more, and in some cases it is not possible to sufficiently reduce the unevenness of the light. In addition, there is also a demand for improved visibility from the side.

FIG. 3 is a diagram showing a light emitting part and light rays in a front view of the indicator light device;

An embodiment of the present invention will be described in detail with reference to the drawings. 1 is a front view of an indicator light device 1 according to the first embodiment of the present invention, FIG. 2 is a perspective view of the indicator light device 1, and FIG. 3 is an AA' cross section of FIG. Figures are shown respectively. Note that the internal structure of the fire transmitter 3 is omitted in FIG. This indicator light device 1 is used by being embedded in the wall surface of a building or in an equipment storage box provided on the wall surface of the building. It has a light display portion 14 indicating the position, and is configured so that the light from the light display portion 14 can be visually recognized from the front or side of the indicator lamp device 1 .

The indicator light device 1 has a flat cylindrical housing 2 , and a fire transmitter 3 as a disaster prevention device is arranged in the center of the housing 2 . The fire transmitter 3 has a circular operation portion 20 and a substantially rectangular door portion 21 on its front surface. When a fire breaks out, a fire breakout signal can be sent to other devices by pressing the operation unit 20 consisting of a push button switch. Further, the door portion 21 is formed so as to be openable and closable, and a terminal (not shown) for connecting an emergency telephone is arranged inside.

The housing 2 has a front surface portion 10 exposed to the indoor side, and a peripheral surface portion 11 embedded in a wall surface or a device housing box and not exposed to the indoor side. As shown in FIG. 3, the front part 10 is arranged so as to be substantially flush with the wall surface serving as the installation surface or the interior surface 4 of the equipment storage box. That is, only the front part 10 of the housing 2 is exposed to the indoor side. The fire transmitter 3 described above is arranged in the central part of the front part 10, and two arcuate recesses 12 are arranged along the outer periphery thereof. The recesses 12 are arranged so as to be symmetrical in the left and right direction.

The recessed portion 12 has an inner peripheral side surface 12a formed by a substantially vertical surface facing the back side with respect to the surface of the front surface portion 10, and from the inner peripheral side end portion of the inner peripheral side surface 12a to the outer peripheral end portion of the recessed portion 12 on the front portion 10 side. , and an outer peripheral side surface 12b composed of an inclined surface having a substantially arcuate cross section. Therefore, the outer peripheral side surface 12b is inclined and curved from the inner side of the housing 2 toward the front surface portion 10 along the direction from the inner peripheral side to the outer peripheral side of the housing 2. .

An inner peripheral side surface 12a of the concave portion 12 is a translucent portion 13 entirely formed of a red translucent material. Inside the translucent part 13, a light emitting part 16 such as an LED is arranged. A plurality of light-emitting portions 16 are provided along the circumferential direction of the recess 12 . The light from the light emitting section 16 is divergent light, and the surface of the translucent section 13 serves as a lens surface that further diverges the divergent light from the light emitting section 16 . Note that the surface of the translucent portion 13 may not have a lens surface formed thereon. Further, the translucent portion 13 is not limited to being made of a red translucent material, and may be made of a colorless transparent or milky white material, for example.

An optical film 18 for diffusing light is provided on the surface of the translucent portion 13 . The optical film 18 is a transparent film on which a large number of fine UV resin projections are formed, and is capable of diffusing light when transmitted in the thickness direction. This makes it possible to further diffuse the light from the translucent portion 13 and prevent the light from concentrating in one place. The configuration of the optical film 18 is not limited to the one described above, and the optical film 18 does not necessarily have to be provided on the surface of the translucent portion 13 .

The light emitting portion 16 is arranged to emit light from the side opposite to the translucent portion 13 and the optical display portion 14, that is, from the outer peripheral side of the housing 2 toward the inner peripheral side. A light reflecting portion 17 is arranged on the inner peripheral side of the light emitting portion 16 of the housing 2 so as to face the light emitting portion 16 . Therefore, the light from the light emitting section 16 travels toward the light display section 14 through the light transmitting section 13 after being reflected by the light reflecting section 17 .

An outer peripheral side surface 12b of the concave portion 12 serves as a light display portion 14 whose entirety is a surface such as a mirror capable of reflecting light. The surface of the optical display unit 14 may be a reflecting surface that reflects light, and is not limited to a mirror, and may be formed by a glossy surface, high-brightness coating, plating, or the like. Since the outer peripheral side surface 12b of the light display portion 14 has the above-described shape, the light display portion 14 is arranged so as not to protrude from the front portion 10 toward the indoor side.

FIG. 4 shows an enlarged view of the vicinity of the light emitting section 16 and the optical display section 14 in FIG. In this figure, the optical path through which the light from the light-emitting portion 16 reaches the light-transmitting portion 13 is indicated by a broken line. As shown in FIG. 4 , the light from the light-emitting portion 16 is divergent light, and first travels toward the light-reflecting portion 17 of the housing 2 , then is reflected by the light-reflecting portion 17 and travels toward the light-transmitting portion 13 . to proceed. Since the surface of the translucent portion 13 is a lens surface as described above, the light transmitted through the translucent portion 13 spreads further and is reflected by the light display portion 14 toward the indoor side.

As shown in FIG. 2, the optical display section 14 can be visually recognized even from the oblique front of the housing 2 . In addition, since the optical display section 14 has an arcuate cross section in the left-right direction, the light from the light emitting section 16 is directed not only toward the front of the housing 2 but also toward a wider range diagonally forward of the housing 2. reflected. With these, the light reflected by the light display section 14 can be visually recognized from a wide range of angles in front of the housing 2 .

The surface of the transparent member 15 is inclined downward from the inner peripheral side to the outer peripheral side. It has an inclined surface that slopes upward toward the side. That is, the housing 2 has a concave shape along the circumferential direction, the bottom being the outer peripheral end of the transparent member 15 . As a result, the light emitted through the translucent portion 13 and the transparent member 15 can be viewed from a wider range of angles in front of the housing 2 .

Only the front part 10 of the housing 2 is exposed, and the light display part 14 is arranged so as not to protrude from the front part 10 to the indoor side. Designability can be improved. On the other hand, the light from the light display unit 14 can be visually recognized from a wide range of angles in front of the housing 2, so that the position of the fire transmitter 3, which is a disaster prevention device, can be confirmed from the front and sides of the housing 2. can be

A plate-shaped transparent member 15 facing in the same direction as the front surface portion 10 is provided in the opening portion of the recess portion 12 . As a result, it is possible to prevent the light from becoming difficult to see due to, for example, contamination of the optical display portion 14 and the translucent portion 13 in the concave portion 12 .

The path of light from the light emitting section 16 will be described in more detail. FIG. 5 shows a perspective view showing the relationship between the light emitting section 16 and the housing 2. As shown in FIG. In this figure, the translucent portion 13 and the transparent member 15 are omitted. A light ray L shown in the drawing represents the center line of the light from the light emitting section 16 . As shown in FIG. 5 , the light emitting section 16 emits light obliquely upward toward the light reflecting section 17 on the inner peripheral side of the housing 2 . Therefore, the direction in which the light from the light emitting unit 16 travels is inclined with respect to all of the radial direction, the circumferential direction, and the height direction of the housing 2 . The light reflected by the light reflecting portion 17 travels toward the outer circumference of the housing 2 . This light is also inclined with respect to all of the radial direction, the circumferential direction, and the height direction of the housing 2, and is incident on the optical display section 14 in an inclined manner. Light traveling from the light reflecting portion 17 toward the outer peripheral side of the housing 2 is reflected by the light display portion 14 and emitted to the outside of the housing 2 .

The light from the light emitting unit 16 is directed toward the inner peripheral side, which is the opposite side in the radial direction of the housing 2 to the direction in which it is finally emitted, and has an angle that is inclined with respect to the radial direction of the housing 2. Therefore, the path of the light to reach the optical display section 14 can be lengthened. Therefore, the light from the light emitting section 16, which is diverging light, spreads sufficiently before reaching the optical display section 14 , so that the unevenness of the light in the optical display section 14 can be reduced. As a result, the design of the indicator lamp device can be improved, and the light reflected by the light display section 14 can be reliably viewed from a wide range.

FIG. 6 shows a front view of the indicator light device 1 showing the light emitting portion 16 and light rays. A plurality of light emitting units 16 are provided in the circumferential direction of the housing 2 as described above. Since the arrangement of the light emitting part 16 and the direction of the light beam are symmetrical, the right half of the figure will be explained here. In the right half of the housing 2, a first light emitting section 16a, a second light emitting section 16b, a third light emitting section 16c, and a fourth light emitting section 16d are arranged along the circumferential direction. The light from the first light emitting section 16a is the light ray L1, the light from the second light emitting section 16b is the light ray L2, the light from the third light emitting section 16c is the light ray L3, and the light from the fourth light emitting section 16d is the light ray L4.

The first light emitting section 16 a and the second light emitting section 16 b arranged in the upper half of the housing 2 emit light toward the lower side of the housing 2 . On the other hand, the third light emitting portion 16 c and the fourth light emitting portion 16 d arranged in the lower half of the housing 2 emit light toward the upper side of the housing 2 . Therefore, the light beams L1 and L2 from the first light-emitting portion 16a and the second light-emitting portion 16b are reflected by the light reflecting portion 17 and the light display portion 14 , and then travel laterally and slightly downward of the housing 2. FIG. The light beams L3 and L4 from the third light emitting portion 16c and the fourth light emitting portion 16d are reflected by the light reflecting portion 17 and the light display portion 14 , and then travel sideward and slightly upward of the housing 2. FIG.

The circumferential positions of the center lines of these lights at the outermost periphery of the housing 2 are within a range of ±45 degrees in the circumferential direction with respect to the 3 o'clock position of the housing 2 . Therefore, a large amount of light is emitted toward the sides of the housing 2, so that when the housing 2 is installed on the wall surface of the building, it is possible to make it easier to visually recognize from the sides of the indicator light device 1. .

In addition, although the number of the light emitting units 16 is eight in the present embodiment, it can be set to another number as necessary. In addition, although the range in which the center line of the light is positioned in the circumferential direction at the outermost periphery of the housing 2 is ±45 degrees in the present embodiment, this range can be set as appropriate. In addition, all the light emitting portions 16 may be arranged so as to face in the same direction in the circumferential direction.

Although the embodiments of the present invention have been described above, the application of the present invention is not limited to the above-described embodiments, and can be applied in various ways within the scope of its technical ideas. For example, in the above-described embodiments, the disaster prevention device is provided integrally with the indicator light device, but the indicator light device may not have the disaster prevention device integrally, and may be installed near the disaster prevention device. good.

In the above-described embodiment, the transparent member 15 is provided on the front portion 10 side of the housing 2, and the translucent portion 13 is provided on the inner side of the housing 2, but there are various configurations and combinations of these. form can be considered. For example, instead of the transparent member 15, a red or opalescent translucent member may be used, or the transparent member 15 may be omitted. Also, the translucent portion 13 can be made of a transparent or opalescent material as described above.

Moreover, in the above-described embodiments, the present invention is applied to a fire alarm as a disaster prevention device, but the present invention can be applied to any disaster prevention device other than the fire alarm.
