<p>The present invention relates to a traffic sign capable of preventing driver and pedestrian accidents by using LEDs to enable a traffic sign to emit light; enabling drivers and pedestrians to secure clear views by using a lamp unit installed at the bottom; and facilitating identification of accidents by using a camera unit to take pictures of the condition of a road. The traffic sign comprises a frame, which is made from a metal material, has a fixing groove formed on the inner side thereof to insert and fix a light guide plate, and is covered with a cover on one side thereof; the light guide plate which is inserted into the fixing groove of the frame, has an insertion groove, which an LED array is inserted in, on the outside of one side thereof and a guide groove formed along the outer surface, is formed of a transparent material, and has a reflection sheet bonded to one side thereof; a dispersion unit evenly dispersing light from the front side of the light guide plate by adhering to the other side of the light guide plate to disperse the light of the LED array of the light guide plate; a heat radiating plate, which adheres to the LED array by being partially inserted in the insertion groove of the light guide plate and radiates heat of the LED array by being combined with one side of the light guide plate; a control unit controlling the operation of the LED array by being connected to the LED array; and a lamp unit irradiating the lower part of the frame with light by being combined with the lower part of the frame and taking pictures through the camera unit by being connected to the control unit.</p> |
