Description

Safety indicator and guidance system using it

The present invention relates to a guide light and a guide system using the same, and more particularly, to a guide light and a guide system using solar energy and radio control signals.

In general, a device for guiding the traffic of a vehicle is installed in a dangerous area of a road such as a pedestrian crossing, a curved road, a steep slope downhill, a bridge, an elevated road, and the like. These devices include safety signs, safety lights with wires, and indicators with batteries.

Looking at such a device, the safety sign or the safety indicator rod using the first luminous paint is a defect that the luminous reflection is properly performed to clean regularly because dust is easily caught. In order to overcome this drawback, it is used as an electric safety indicator and safety signal. In this case, however, wire laying work must be carried out to connect the wires, and they cannot perform their functions in the event of a wire break or power outage. In addition, the installation cost is difficult to install in a number of places, as well as the mountain road difficult to connect the wires, there is a drawback that is difficult.

On the other hand, the safety indicator with the built-in battery has a short discharge time of the battery, there is a need to replace the battery frequently or recharge. In order to overcome this problem, safety indicators using solar and secondary batteries have been proposed, but dust is easily trapped on the solar cells, and thus the solar energy cannot be used sufficiently unless they are frequently wiped. In addition, the safety light only emits the light, but the safety of the road bends the ability to guide the poor. Even in the case of using solar cells, when a guide function was provided by a plurality of safety indicators, wires connecting the safety indicators had to be buried to send a signal to control them. In this case as well, there is a problem due to the wire laying work.

In order to solve the problems of the prior art, an object of the present invention is to provide a safety indicator and a guidance system using the same controlled by a radio signal transmitted wirelessly.

Another object of the present invention is to provide a safety indicator for preventing pollution of solar cells.
