Hereinafter, the operation process of the subject innovation assembled as described above are as follows.

Solar energy is absorbed by the light collecting plate 23, and the absorbed solar energy is converted into electrical energy by charging the battery 24.

In this case, the time for charging the solar cell absorbed by the light collecting plate 23 into the rechargeable battery 24 is preferably as short as possible, and thus, the rechargeable battery 24 needs to use a low operating voltage. In this case, a battery having a working voltage of 1.2 V is used, and the light collecting plate 23 uses an output voltage of DC 1.5V.

The battery 24 is configured to distinguish between day and night by the difference in the output voltage, thereby charging during the day when sunlight is present, and at night to emit the charged energy to emit the LED 26.

That is, when the charging voltage does not occur, the LED 26 is turned on by emitting energy by supplying a voltage, and when the charging voltage is generated, the voltage supplied to the LED 26 is cut off to stop the lighting. A series of processes that turn on and off is performed continuously over time and weather.

Light of the LED 26 that is turned on as described above is the light guide surface 161 on the light emitting projection 16 and the upper surface and cover 40 of the light emitting projection 16 through the diffusion lens 221 configured at the tip of the LED case 213. After reaching the light emitting member 30 through an optical path formed at the bottom, the light emitting member 30 is emitted to the outside by the diverging part 311 composed of several lenses having different refractive angles. At this time, since the emitted light is emitted at a wide angle left and right and up and down, the driving of the LED 26 is allowed to enter the driver's view in any direction, thereby inducing safe driving.

In addition, even if the lighting function of the LED 26 that is lit as described above is damaged, the reflector 312 is able to perform a safe driving induction function in place of the lighting function by reflecting the headlight of the vehicle. .

The road display device of the present invention assembled as described above is to determine the location to install, drill a hole using a certain size of the drill, and then to remove the dirt and dirt on the road surface, the road for the road Pour the epoxy resin to the height of the surrounding asphalt, apply the adhesive to the lower part of the road separation display, insert it into the hole while rotating the separation display so that the adhesive spreads, and press the upper part of the display to By adjusting and removing the epoxy resin flowing out of the display device, it can be easily installed on the road surface.

When the display device of the present invention is installed as described above, the fixing plate 121 on the fixed shaft 12 of the base 10 increases the bearing force by increasing the contact surface with the epoxy resin, and the fixing rib 123 is applied to the rotational force. It protects the display device, and the arrowhead-shaped fixing protrusion 122 configured at the tip protects the display device against the pulling force, thereby preventing the device from protruding from any external shock to perform the display function safely.

As described above, the road display device of the present invention is completed, thereby improving the viewing distance by using the self-luminous function of the solar cell, reducing the maintenance cost, and increasing the viewing angle by increasing the divergence angle of the light. By easily opening and closing the ground of the display device, it is possible to provide a road display device with improved convenience in maintenance.

Accordingly, by improving the vehicle guidance function during night driving, the driver's safety can be secured, and the maintenance of the road can be facilitated, and the cost can be reduced by increasing the service life, thereby improving the reliability of the product. It became.
