 However, the conventional roadside studs individually incorporate the modularized solar cell module, power storage area, LED, reflector, and control circuit into the main body case as described above, which results in a lot of assembly work and productivity. There was a problem that it was bad and the cost was high.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a roadside tack that can be manufactured with less assembling work to improve productivity and reduce cost.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention includes a solar cell, an LED powered by the solar cell, a storage battery charged by the solar cell, and a control circuit for controlling blinking of the LED. A main body case to be installed, and a transparent resin case provided as a part of the main body case above the main body case so as to cover the solar cell and the LED, inside the transparent resin case, and the LED It is characterized in that a reflector is formed around the periphery by aluminum vapor deposition.

[0006]

[Action]

 As described above, the self-luminous roadside tack according to the present invention has the reflector integrally formed with the transparent resin case, so that the number of parts as the roadside tack can be reduced, the work efficiency can be improved, and the cost can be reduced as a product. Can be achieved.

【Example】

 An embodiment of the present invention will be described with reference to FIGS.

1 and 2 are a front view and a plan view of a self-luminous road side tack (hereinafter referred to as a road side tack) according to the present embodiment, FIG. 3 is a sectional view of the same road side tack, and FIG. 4 is a block of the same road side tack. It is a circuit diagram.

As shown in FIGS. 1 to 3, the roadside tack of the present embodiment includes an LED 2, a solar cell 3, a storage battery (secondary battery) 4 and an LED 2 charged by the solar cell 3 in a main body case 1. A control unit 5 for controlling the lighting operation of the is attached.

A transparent resin case 6 is provided so as to cover the upper portions of the LED 2 and the solar cell 3. In this transparent resin case 6, a reflector 7 is formed at a portion corresponding to the periphery of the LED 2. The reflector 7 is previously integrally formed inside the transparent resin case 6 by, for example, aluminum vapor deposition.

The upper surface of the transparent resin case 6 has a lens-like curved surface structure so as to efficiently collect external light. As a material for the transparent resin case 6, for example, polycarbonate is used.

The body case 1 and the bottom plate 8 are integrated by screws 9. In addition, the road side tacks of this embodiment are mounted and fixed to the road by inserting the bolts provided on the road side into the installation bolt holes 10 formed on both sides of the body case 1 shown in FIG. I am trying to fix it. Since the roadside tack according to the present embodiment is integrally formed with the transparent resin case 6 and the reflector as described above, it is possible to reduce the number of parts and improve workability.

Next, the operation of the roadside tack control circuit 5 of this embodiment will be described with reference to FIG. In the figure, 2 is an LED, 3 is a solar cell, 4 is a storage battery, 15 is a backflow prevention diode, 16 is an overcharge prevention circuit, 17 is an illuminance detection circuit, 18 is a switch circuit, 19 is a blinking circuit, and 20 is a diode. is there.

First, regarding the operation of each unit, the solar cell 3 receives sunlight to generate electric power.

The backflow prevention diode 15 prevents a current from flowing from the electricity storage place 4 to the solar cell 3 at night. The overcharge prevention circuit 16 prevents the overcharge of the electricity storage device 4 by internally consuming the electric power generated by the solar cell 3 when the voltage of the electricity storage device 4 becomes equal to or higher than a set value when the electricity storage device 4 is charged.

The illuminance detection circuit 17 receives the output of the solar cell 3 and detects the brightness on the road, that is, whether it is daytime or nighttime.

The switch circuit 18 receives the signal from the illuminance detection circuit 17 and is turned on at night and turned off during the day.

The electricity storage place 4 is charged by the electric power generated by the solar cell 3 in the daytime, and supplies electric power for emitting light to the LED 2 at night.

The blinking circuit 19 drives the LED 2 to blink.

The diode 20 acts to keep the voltage of the solar cell 3 higher than the operating voltage of the illuminance detection circuit 17 so that the illuminance detection circuit 17 does not operate even if the overcharge prevention circuit 16 operates.

The operation of the control circuit will be described below.

During the daytime, the solar cell 3 generates electric power to charge the electricity storage place 4, and at the same time, the electricity is supplied to the overcharge prevention circuit 16 and the illuminance detection circuit 17. The illuminance detection circuit 17 gives a signal indicating that it is daytime to the switch circuit 18, and the switch circuit 18 is turned off.

Therefore, power is not supplied to the blinking circuit 19, and the LED 2 does not emit light. At night, the illuminance detection circuit 17 gives a signal indicating that it is night to the switch circuit 18, and the switch circuit 18 is turned on. When the switch circuit 18 is turned on, the electricity is stored in the electricity storage area 4 and supplied to the blinking circuit 19, and the LED 2 is driven to blink. At dawn, the switch circuit 18 is turned off by the detection signal from the illuminance detection circuit 17, and the power supply to the blinking circuit 19 is stopped.

[Effect of device]

 As described above, in the present invention, by integrating the transparent resin case of the solar cell and the reflector, the number of parts can be reduced, the assembling work can be simplified, the productivity can be improved, and the cost can be reduced. Can be achieved.
