TRAFFIC SIGN SYSTEM

摘要

PURPOSE: A traffic signal system is provided to change lighting of a signal according to the passage of vehicles by using a pressure sensor for recognizing the vehicles. CONSTITUTION: A sunlight generating unit(110) produces electricity with sunlight. An illuminance sensor(120) senses surrounding illuminance. A stop line light emitting unit(130) displays a stop line of a vehicle. A light emission degree of the stop line light emitting unit is changed based on the sensed illuminance. A pressure sensor(140) senses the passage of the vehicle. A control unit controls a traffic light unit.
