Description

  The present invention relates to an illuminating lamp device that is provided on a standing body such as a power pole, a lamp pole, and a gate pole and supplies illumination light, and more specifically, in a configuration that supplies illumination light from an upper part of the standing body. The present invention also relates to an illuminating lamp device capable of easily replacing the automatic flasher.

Street lights and security lights, which are street lighting equipment, have light source lamps attached as light sources on the tops of power poles and light poles, etc., so that they can be turned on at night and turned off during the day. There is an automatic flasher that senses brightness and automatically turns on and off the light source lamp.
When such bulbs such as street lights and security lights run out and defective automatic flashing devices occur, it is necessary to replace them. It is done at high place using a car.

For this reason, if such replacement work is entrusted to managers of neighborhood associations that manage street lights and security lights, it will be a heavy burden for the managers, and it is also dangerous because it is work at high places. become. Especially in places where live parts such as distribution lines and transformers are close to each other, specialized skills are required and great care must be taken.
Therefore, it is generally difficult for managers of street lights and security lights (members of residents' associations) to carry out the replacement work themselves, so it is necessary to request a replacement work from a specialized construction company, resulting in high costs. There is an inconvenience.

  In order to avoid such inconvenience, as shown in Patent Document 1 described below, a light source unit that generates and outputs light, and a light transmission unit that transmits light output from the light source unit to a user, A configuration in which an illumination light supply system including an illumination light radiating unit that radiates light transmitted by the light transmission unit to space is used, and the lamp of the light source unit can be replaced at a place different from the illumination light radiating unit It is effective to adopt

Japanese Unexamined Patent Publication No. 2003-7102

  However, the illumination light supply system described above is desirable as a configuration for supplying illumination light. However, in the case where the ambient brightness is sensed and turned on and off individually, such as street lights and security lights, Since it is necessary to provide an automatic flasher for each illuminating lamp, there is an inconvenience that if the automatic flasher is defective, replacement work at the same high place as before is required for each illuminating lamp. In addition, in an outdoor lamp, since the installation interval is long unlike an indoor lamp, a configuration in which a light source is shared by a plurality of outdoor lamps is not suitable.

  The present invention has been made in view of such circumstances, and in a device that is provided on a standing body such as a power pole or a light pole and supplies illumination light from above, it is easy to replace light sources and automatic flashers. The main problem is to provide an illumination lamp device that can be used.

  In order to achieve the above object, an illuminating lamp device according to the present invention is an illuminating lamp device that irradiates light from an upper part of a standing body, and is provided on the upper part of the standing body to emit illumination light downward.

  Therefore, since the storage box contains an automatic flasher in addition to the light source unit, if the tube breaks or the automatic flasher is defective, the replacement work can be done by replacing the light source unit or automatic flasher in the storage box. Is completed, the work at a high place where the illumination light emitting portion is provided becomes unnecessary.

Here, the first light transmission means includes an aggregation mechanism that aggregates the light emitted from the light source unit, and an optical fiber cable that transmits the light aggregated through the aggregation mechanism, The illumination light radiating unit includes a diffusion mechanism for diffusing the light transmitted through the optical fiber cable, and a radiation direction control mechanism for directing light diffused by the diffusion mechanism downward. The second light transmission means may include a second optical fiber cable that transmits the light taken in by the daylighting unit to the automatic blinker.
In such a configuration, the aggregation mechanism is configured using a concave mirror, a convex lens, a concave lens, or the like, the diffusion mechanism is configured using a concave lens, a convex mirror, or the like, and the radial direction control mechanism is configured using a convex lens, a concave mirror, or the like. May be configured. In the above-described configuration, in order to obtain a sufficient amount of light, a plurality of the aggregation mechanisms, optical fiber cables, diffusion mechanisms, and radiation direction control mechanisms may be provided.

Further, the first light transmitting means guides the light emitted from the light source unit upward, and guides the light guided upward by the first reflection mechanism to the illumination light emitting unit. A second reflection mechanism, and the illumination light radiating unit includes a radiation direction control mechanism for directing light guided through the second reflection mechanism downward, and A third reflection mechanism that guides the light captured by the daylighting unit downward, and a fourth reflection mechanism that guides the light guided downward by the third reflection mechanism to the automatic flasher. You may make it comprise and have a reflection mechanism.
In such a configuration, the first to fourth reflection mechanisms and the radiation direction control mechanism can be configured by reflecting mirrors alone or in combination, so that the configuration can be simplified by eliminating the need for an optical fiber cable. It becomes.

  In the above configuration, when the installation position of the storage box is limited, the storage box may be embedded in the standing body or the ground. Further, the first and second light transmission means may be provided outside the standing body or inside. Further, the storage box and the daylighting unit may be provided on another standing body different from the standing body provided with the illumination light radiating unit.

  As described above, according to the present invention, the illumination light radiating part is provided on the upper part of the standing body, and light is generated and emitted from the storage box provided below the illumination light radiating part of the standing body. A light source unit and an automatic flasher that turns on and off the light emission of the light source unit according to the detected illuminance are housed, and the light emitted from the light source unit is transmitted to the illumination light emitting unit by the first light transmission means, Since the light taken in by the daylighting unit is transmitted to the automatic flasher by the second light transmission means, it is easy to replace the light source and the automatic flasher by placing the storage box in a place where it is easy to work Can be done. In addition, since work can be performed in a low place, the work can be performed safely.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described with reference to the accompanying drawings.

  In FIG. 1, the structural example which applied the illuminating lamp apparatus 1 which concerns on this invention to the external lamp provided in the standing structures 2, such as a utility pole or a lamp pole, is shown. The illuminating lamp device 1 includes an illumination light radiating portion 4 that is fixed to a brace 3 above the standing body and radiates light downward, and a storage provided at a position below the illumination light radiating portion 4. A box 5; a light source unit 6 that generates and emits light by a power source stored in the storage box 5 and supplied from the outside; and a sealed space that is stored in the storage box 5 and blocks light from the light source unit 6 7, an automatic flasher 8 for turning on / off the light emission of the light source unit 6 according to the detected illuminance, a daylighting unit 9 for taking in light around the standing body 2, and a light source unit 6 includes a first optical fiber cable 11 that transmits the light emitted from the illumination light radiating unit 4 and a second optical fiber cable 12 that transmits the light collected by the lighting unit 9 to the automatic flasher 8. Configured.

  In this example, the storage box 5 is fixed to the side surface of the standing body 2 by a binding band or the like at a height of about 1.5 m from the ground, and has an opening / closing door (not shown). 6 and the automatic flasher 8 can be accessed.

  The light source unit 6 generates light by a lighting circuit (not shown) by a power source supplied via a power line 13 guided downward through a resin tube provided along the standing body 2, and is a metal halide lamp. It is possible to use a high-pressure discharge lamp such as a high-pressure mercury lamp, an electrodeless discharge lamp, a fluorescent lamp, an incandescent lamp, or the like. As shown in FIG. 2, the light source unit 6 is attached inside a concave reflecting mirror (reflector) 15, and the light emitted from the light source unit 6 is reflected directly or by the reflecting mirror 15. The end face of the first optical fiber cable 11 is guided to the convex lens 16 facing the reflecting mirror, condensed by the convex lens 16 and converted into parallel light by the concave lens 17 disposed between the first optical fiber cable 11 and the parallel light. So that the light is incident vertically. An aggregating mechanism that aggregates the light emitted from the light source unit 6 by the reflecting mirror 15, the convex lens 16, and the concave lens 17 and guides the light to the first optical fiber cable is configured.

  The aggregation mechanism and the first optical fiber cable need only be one set. However, if a sufficient amount of light cannot be obtained, as shown in FIG. Confronting concave lenses 17 and optical fiber cables 11 are provided at four positions on the side surface of the light source unit 6 at intervals of 90 degrees, and further disposed above the light source unit 6 to collect from a maximum of five locations (five surfaces). You may make it light.

The light aggregated through the above aggregation mechanism is transmitted to the illumination light radiating unit 4 provided in the fixture main body 19 of the outside lamp via the first optical fiber cable 11. In this example, the first optical fiber cable 11 is led to the illumination light radiating section 4 in the instrument main body 19 through a resin tube attached along the side surface of the standing body, and as shown in FIG. Is opposed to the concave lens 20 so that the light emitted from the first optical fiber cable 11 is diffused through the concave lens 20. Thereafter, the light passes through the convex lens 21 and is emitted downward as parallel light.
The concave lens 20 constitutes a diffusion mechanism for diffusing the light output from the first optical fiber cable, and the convex lens 21 constitutes a radiation direction control mechanism for directing the diffused light downward.

As another example, as shown in FIG. 5, the tip of the first optical fiber cable 11 faces the convex mirror 22 facing downward, and a predetermined interval is provided so as to cover the periphery of the convex mirror 22. The concave mirror 23 is disposed downward, and the light emitted from the first optical fiber cable 11 is reflected and diffused by the convex mirror 22, and then the diffused light is further reflected by the concave mirror 23 to produce parallel light. May be emitted downward.
In this example, the convex mirror 22 constitutes a diffusion mechanism that diffuses the light output from the first optical fiber cable 11, and the concave mirror 23 constitutes a radiation direction control mechanism that directs the diffused light downward. Has been.

  Note that the diffusion mechanism (concave lens 20 or convex mirror 22) or convex lens 21 or concave mirror 23 only needs to be one set. However, when a sufficient amount of light cannot be obtained, for example, as shown in FIG. Depending on the number of optical fiber cables 11, concave lenses 20 (or convex mirrors 22) and convex lenses 21 (or concave mirrors 23) may be provided side by side. Further, the convex lens 21 and the concave mirror 23 may be rotatable and displaceable, and the light emission direction and the radiation range may be changed.

  As shown in FIG. 7, the daylighting unit 9 for taking in the brightness around the upright body 2 is attached behind the outer lamp body 19, that is, at a position not affected by light from the illumination light emitting unit 4. For example, a daylighting lens 25 composed of a fisheye lens, a Fresnel lens, or the like is provided at the tip of the second optical fiber cable 12, and the periphery of the daylighting lens 25 is covered with a translucent cover 26 so that it is not exposed to direct sunlight. In addition, the daylighting lens 25 is configured not to become dirty.

  Then, the light collected by the daylighting unit 9 is guided to the light receiving unit 8a of the automatic flasher 8 in the sealed space 7 provided in the storage box 5 through the second optical fiber cable 12. ing. In this example, the second optical fiber cable 12 is guided to the sealed space 7 in the storage box through a resin tube attached along the side surface of the upright body, and the distal end portion of the second optical fiber cable 12 is a light receiving portion of the automatic flasher 8. It directly faces 8a. In addition, you may make it oppose the front-end | tip part of the 2nd optical fiber cable 12 through the lens etc. which are not shown in figure.

  Therefore, when the brightness around the standing body 2 is smaller than the predetermined illuminance, the light taken in by the daylighting unit 9 is reduced, and the amount of light transmitted to the automatic flasher 8 via the second optical fiber cable 12 Therefore, the automatic flasher 8 operates to start energization of the light source unit 6 and the light source unit 6 emits light. For this reason, the light emitted from the light source unit 6 is incident perpendicularly to the end face of the first optical fiber cable 11 through the aggregation mechanism, propagates through the first optical fiber cable 11, and passes through the first optical fiber cable 11. It is guided to the illumination light radiating unit 4. Then, the light emitted from the end face of the first optical fiber cable 11 is diffused by the concave lens 20 (or the convex mirror 22) facing it, and then converted into parallel light by the convex lens 21 (or the concave mirror 23). Radiated downward. In addition, when the brightness around the standing body 2 exceeds a predetermined illuminance, the amount of light transmitted to the automatic flasher 8 through the second optical fiber cable 12 increases, so that the light source unit 6 is energized. The light source unit 6 is turned off and the radiated light from the illumination light radiating unit 4 disappears.

  Therefore, according to such an illuminating lamp device 1, the light source unit 6 and the automatic flasher 8 are stored in the storage box 5 provided at the lower part of the standing body 2. When replacement is necessary due to failure of 8, the opening / closing door of the storage box 5 may be opened and the light source unit 6 and the automatic flasher 8 may be replaced. For this reason, it is possible to easily replace the light source unit 6 and the automatic flasher 8, and there is no burden on the operator. Work can be performed.

  In the above-described configuration, the example in which the first and second optical fiber cables 11 and 12 are arranged outside the standing body 2 is shown. However, if the standing body 2 has a hollow structure, You may make it pass the inside. In the above example, the standing body 2 is applied to an installation pole such as a utility pole, a lamp pole, and a gate pole. However, the same applies to an electric lamp provided on a standing body such as a gate wall. A configuration may be adopted.

  In FIG. 9, the other structural example of the illuminating lamp apparatus 1 is shown. In this example, instead of using an optical fiber, an optical path is formed by using only a reflecting mirror so that light from the light source unit 6 is guided to the illumination light emitting unit 4 and taken in by the daylighting unit 9. The emitted light is also guided to the automatic flasher 8 disposed in the sealed space 7 of the storage box 5.

  Specifically, a first side passage 31 that extends in the vertical direction inside the upright body 2 and that is open laterally at the top and bottom, and extends in the vertical direction adjacent to the first side passage 31. And a second side passage 35 having upper and lower sides opened laterally, and the light emitted from the light source unit 6 is reflected by the concave mirror 30 to be a first side passage inside the standing body 2. The light is guided from the light source unit 6 by the first reflecting mirror 32 disposed at the lower part of the first side path 31 (by changing the optical path by about 90 degrees) and guided upward. The light transmitted from below is reflected by the second reflecting mirror 33 disposed at the upper part of the first side path 31 (by changing the optical path by about 90 degrees) and guided to the illumination light emitting unit 4. .

  In this example, the illumination light radiating section 4 is constituted by a plurality of reflectors 34 arranged in the outer lamp body 19 so as to be displaced along the optical path, and reflects the light reflected by the second reflecting mirror 33. To radiate downward. Here, the reflector 34 may be formed of a plane mirror, a convex mirror or a concave mirror, and may be controlled to rotate in the vertical and horizontal directions to change the light emission direction. Good.

In addition, the light taken from the daylighting unit 9 is guided to the upper part of the second side path 35, and the light from the daylighting part 9 is guided by the third reflecting mirror 36 arranged at the upper part of the second side path 35. The light is reflected (the optical path is changed by about 90 degrees) and guided downward, and light from above is reflected by the fourth reflecting mirror 37 disposed at the lower part of the second side path 35 (the optical path is changed by about 90 degrees). The light is guided to the light receiving portion 8a of the automatic flasher 8 of the storage box 5.
In such a configuration, since it is not necessary to route the optical fiber cable, the structure can be simplified and the illuminating lamp device 1 can be constructed at a low cost.

  In the above configuration, an example in which the storage box 5 is attached to the outside of the standing body (electric pole or light pole) 2 is shown. However, when the installation location is restricted or the installation location is likely to collide, In some cases, as shown in FIG. 10 (a), even if the storage box 5 is buried in the ground, the storage box 5 is erected as shown in FIG. 10 (b). You may make it embed | buried inside.

  Furthermore, in the above-described configuration, an example is shown in which the standing body 2 is provided with the illumination light emitting unit 4, the storage box 5 in which the light source unit 6 and the automatic flasher 8 are stored, and the daylighting unit 9. However, when it is not possible to attach the storage box 5 that houses the light source unit 6 and the automatic flasher 8 to the standing body 2 to which the illumination light emitting unit 4 is mounted, for example, because it is difficult to ensure safety. In addition, when it is difficult to enter the standing body 2 because it is erected on the residential land or on a slope with a lot of weeds, as shown in FIG. And the 2nd optical fiber cables 11 and 12 may be constructed, and the storage box 5 may be provided in the lower part of adjacent standing body 2 '.

  Also, in the case where the standing body 2 is under a viaduct or in a thick tree and it is dark even in the daytime, only the daylighting section 9 is placed in another standing position as shown in FIG. The illumination light emitting unit 4 is provided via the second optical fiber cable 12 by attaching the second optical fiber cable 12 between the upright bodies and installing the second optical fiber cable 12 between the upright bodies and taking in the light taken from the daylighting unit 9. You may make it transmit to the storage box 5 of the standing body 2 lower part.
