<p>An LED(Light Emitting Diode) lamp control system having an emergency guide function is provided to control lighting in a tunnel at an accurate time through a tunnel lamp control system with a GPS(Global Positioning System) satellite receiver. An LED(Light Emitting Diode) lamp control system having an emergency guide function includes an illumination detection sensor(110), a sensor trouble monitoring unit(120), a GPS(Global Positioning System) module(130), an operation module(140), a communication module(150), a fault alarming unit(160), and an electric signboard(186). The illumination detection sensor detects sunlight illumination of a tunnel entrance and converts the sunlight illumination into a digital signal to output the digital signal. The sensor trouble monitoring unit monitors a trouble of the illumination detection sensor. The fault alarming unit alarms fault occurrence when a fault occurs in a system or the illumination detection sensor. The electric signboard visually provides a driver with circumstances in a tunnel and circumstance information of a tunnel exit.</p> |
