<p>A controlling and working method of a mark system of light emitting diode is provided to minimize damage when accident happened by using radio communication system. A tunnel LED approach light system is comprised of a luminance sensor(100), a remote control apparatus(200) and a tunnel LED induction lamp(300). The luminance sensor senses the brightness of inside by the external illumination variation. A remote control receives brightness from the luminance sensor and analyzes it. The tunnel LED induction lamp is brightness data of the light comprised of a step for controlling the brightness of the LED lamp it receives from the remote control equipment.</p> |
