BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a line light emitting device suitable for being laid in a line along both sides of a road boundary or a passage in a site to guide people at night.

[0002]

2. Description of the Related Art Conventional equipment used for guiding at night has laid poles and tacks with reflecting mirrors along roads and passages, and laid lamps that glow with commercial power.

[0003]

In the above prior art, the type that emits light by reflection requires a separate light source, and the reflected light is limited depending on the distance to the light source, the condition of the incident angle of light and the viewing angle. However, there is a problem that the visibility is deteriorated due to the adhesion of dust and the like. Also, the type that illuminates the lamp with a commercial power source requires wiring work, which increases the cost.
There are problems that the wiring is exposed due to an accident or excavation of road construction, and there is a risk of electric shock, and there is a possibility that the light emitting function may stop due to a power failure at the time of a disaster.

[0004]

According to the present invention, a point light source such as an LED is embedded in an elongated rod-shaped transparent body, a reflector having a large number of minute holes is provided above the transparent body, and a diffuse reflection surface is provided on the bottom surface of the transparent body.
A line light emitting device comprising: a line light emitting body provided with a reflecting surface on a peripheral surface; a solar cell panel for converting solar energy into electric power; and a storage battery for storing electric power of the solar cell panel and supplying the electric power to the light emitting body. .

[0005]

In the present invention, of the light emitted from the point light source in the transparent body, most of the light emitted upward is reflected downward by the upper reflector, and part of it is a large number of small holes in the reflector. And diverge upward. Further, the light emitted from the point light source to the side or downward and the light reflected downward by the reflector are reflected and scattered by the irregular reflection surface and the reflection surface of the bottom surface and the peripheral surface, and almost entirely from the transparent body surface. Penetrates evenly,
The transparent body surface emits a uniform line. Therefore, the visibility is extremely good, and it is hardly affected by the adhesion of dust or the like. In addition, since the line illuminator uses a solar cell to emit light, it does not require any wiring equipment and does not use a commercial power source, so there is no cost for installation and maintenance, and there is no power outage during a disaster. It is not affected and there is no risk of electric shock even if it is destroyed in an accident.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a top view of a line light emitting device 1 according to an embodiment of the present invention, FIG. 2 is a side view of the line light emitting device 1, and FIG. 3 is a sectional view of a line light emitting body.

The line light emitting device 1 includes a solar cell panel 13,
It comprises a controller case 3 in which a storage battery and a control circuit are integrated, and two line light-emitting bodies 2 connected in parallel to the controller case 3. In the line luminous body 2, as shown in FIG. 3, a hole 5 is bored in the lower surface of a transparent body 4 made of transparent acrylic, and a red LED 6 is inserted therein. Also,
A porous aluminum plate is adhered to the upper surface inside the hole 5 as a reflection plate 7 having a large number of minute holes. A silver reflective tape is adhered to the peripheral surface of the transparent body 4 to form a reflective surface 8. Asperities 9 are formed on the bottom surface of the transparent body 4, and this surface is a rough rough surface. Further, a red reflection tape 10 is laid below the bottom surface, and the irregular reflection surface and the reflection tape 10 form a diffuse reflection surface. The transparent body 4 is framed by a stainless steel frame 11, and the transparent body 4 and the frame 11 are also framed.
A caulking material 12 is provided between and to waterproof the inside. When the LED 6 emits light, red light is scattered and reflected by the reflection plate 7 (a part of which is transmitted), the uneven bottom surface, the reflection surface 8 and the red reflection tape 10 and is uniformly transmitted from the surface of the transparent body 4, The entire surface emits red light in a substantially uniform manner. In the controller case 3, the solar cell panel 13 is provided on the surface, and the storage battery and the control circuit are provided inside. The control circuit charges the storage battery with the electromotive force of the solar panel in the daytime, detects the darkness outside by the electromotive force of the solar panel from the evening to the night, and when the predetermined darkness is reached, the LED powers the storage battery. To make it emit light.

In this embodiment, two line light emitters are connected to the controller case, but the number of line light emitters is not limited to two, but is arbitrary. However, there are limitations due to the capacity of solar cells and storage batteries. Since the width of the line illuminator can be made extremely thin, around 10 mm, it is embedded in the joint between the paving stones and laid, and the controller case is cut out with a portion of the paving stones installed, which makes it very attractive. Can be used well.

[0009]

The line light emitting device of the present invention has a line emission in which the surface of the transparent body emits light uniformly, so that it has excellent visibility and is not easily affected by dust or the like. Also,
Since the line illuminator is made to emit light by a solar cell, it does not require wiring facilities and does not use a commercial power source, so it does not cost much for installation and maintenance.
It is not affected by power outages in the event of a disaster, and there is no risk of electric shock when it is destroyed by an accident. Since the line illuminant can be manufactured extremely thin, it can be used very well by embedding it in the joint of the paving stone.
