The present invention provides a traffic light using sunlight, capable of displaying four types of signals through one signal display part, and being sufficiently operated with solar energy generation by being operated with lower power. The traffic light using sunlight includes: a signal display part installed by distributing a plurality of multiple red, green, and yellow LEDs; a signal control part controlling whether to turn on the red, green, and yellow LEDs, installed in the signal display part, according to a traffic signal; a solar cell part generating electricity by using the sunlight; a battery part storing the electricity, generated from the solar cell part; and a DC voltage conversion part converting a voltage of the battery part into a voltage to make the LEDs of the signal display part emit light, and then supplying the voltage to the signal control part.

    본 발명은 하나의 신호표시부에서 4가지 신호를 표시하는 것이 가능하며 저전력으로 구동이 이루어지므로 태양광 발전으로 충분히 작동하는 것이 가능한 태양광을 이용한 교통신호등을 제공한다. 본 발명의 태양광을 이용한 교통신호등은 복수의 적색, 녹색, 황색 엘이디가 분산 배열되어 설치되는 신호표시부와, 신호표시부에 설치된 적색, 녹색, 황색 엘이디에 교통신호에 따라 점등여부를 제어하는 신호제어부와, 태양광을 이용하여 전기를 생성하는 솔라셀부와, 솔라셀부로부터 생성된 전기가 저장되는 배터리부와, 배터리부의 전압을 신호표시부의 엘이디를 발광하기 위한 전압으로 변환시켜 신호제어부로 공급하는 직류전압변환부를 포함한다.
