<p>Disclosed is a road marker lamp for controlling a digital wireless communication using solar energy. The road marker lamp for controlling the digital wireless communication using the solar energy includes a light emitting unit, a solar energy concentration unit which supplies power to the light emitting unit, a communication unit which communicates with a communication device formed on an external vehicle and transmits and receives information about the flicking state of the light emitting unit from the communication device by communicating with the communication device formed on the external vehicle, and a control unit which drives the solar energy concentration unit according to the information about the flickering state which is transmitted to and received from the communication unit. Thereby, an environmental pollution is prevented by self-generation in the road marker lamp. Energy is saved by minimizing power consumption. The reliability of transmission data is increased by transmitting a signal related to the flickering through communication with the vehicle which drives on the road. A quick response to the data transmission is performed.</p> |
