The present invention relates to a traffic light which provides additional information. The traffic light of the present invention is equipped with at least one LED and, when activated, emits light to output a color or symbol through the LED to provide traffic signal information. The traffic light comprises: at least one signal unit which provides additional information other than traffic signal information using on/off cycles of the LED; and a control unit on/off controlling the LED based on a frequency in accordance with the additional information to be provided. As a result, the traffic light has the effect of enabling safer and more efficient autonomous driving because autonomous vehicles can recognize additional information other than the traffic signal information through on/off cycles.
본 발명은 추가 정보를 제공하는 신호등에 관한 것으로, 본 신호등은 적어도 하나의 LED가 구비되고 활성화되면 LED를 통해 색상 또는 기호가 출력되도록 발광하여 교통신호 정보를 제공하며, LED의 on/off 주기를 이용하여 교통신호 정보 외의 추가 정보를 제공하는 적어도 하나의 신호부와, 제공하고자 하는 추가 정보에 따른 주파수 기초하여 LED를 on/off 제어하는 제어부를 포함한다. 이에 의해 본 신호등은 자율주행 차량이 on/off 주기를 통해 교통신호 정보 외의 추가 정보를 인식할 수 있어 보다 안전하고 효율적인 자율주행이 가능토록 하는 효과가 있다.
