Display device using solar light {The indication Apparatus for using the solar beam}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for protecting high voltage lines or electric wires or communication lines (hereinafter referred to as "cables"), and more particularly, to a display device using sunlight that enables the location of cables to be identified at night.

In general, roads and residential areas have cable lines for power supply and communication lines or optical cables for communication. In particular, cable lines for transmitting high voltage power are still installed on the ground, unlike communication lines and optical cables. Installing a cable on the ground like this may cause a safety accident. For example, when a driver of a vehicle passes through under a cable traversing the road without inadvertently checking the position of the cable, the cable may be broken by the load on the loading box of the vehicle. Therefore, in the related art, in order to solve this problem, a ground clearance sign is attached to the cable using a fastening means such as a wire.

1 is a view showing the structure of a ground clearance display panel according to the prior art. As shown in Figure 1, the conventional ground clearance sign is simply a letter display on the plate of the same material as PVC. These ground level signs helped to identify the location of the cable by drilling a hole in the top of the sign and using a wire to tie it to the cable. However, at night there is a problem that such a ground height sign is not identified at all, and when the worker connects the sign to the cable, it is cumbersome to install because the work must be tied to the cable.

Therefore, the present invention has been derived to solve the above-mentioned problems with the above-mentioned ground clearance sign, and the present invention uses solar energy to make the light emitting part blink at night, so that the existence of a cable can be checked using sunlight. The purpose is to provide a device.

Another object of the present invention is to provide a display device using sunlight that can be easily installed in a cable.
