The present invention relates to safety traffic lights using LED. The safety traffic lights comprise four states: a stop state (a) where all of upper LEDs (112) are completely turned on an hourglass shaped LED panel; a transitional state (a) where the upper LEDs (112) are gradually turned off from the top while lower LEDs (113) are gradually turned on; a walking start state (b) where the lower LEDs (113) are completely turned on; and a walking progress state (b) where the lower LEDs (113) are completed turned off while the lower LEDs (112) are gradually turned on. By this composition, the present invention can inform the pedestrians of remaining time until the light changes through hourglass animation.

    본 발명은 LED를 이용한 안전 신호등에 관한 것으로서, 모래시계 형상의 LED패널에서 상측LED(112)를 완전 점등한 보행정지(a) 상태에서 상측LED(112)를 순차적으로 소등하면서 동시에 하측LED(113)를 순차적으로 점등하는 과정으로 이루어지는 정지대기상태(a')와, 상기 하측LED(113)를 완전 점등한 보행시작(b) 상태에서 하측LED(113)를 순차적으로 소등하면서 동시에 상측LED(112)를 순차적으로 점등하는 과정으로 이루어지는 보행진행상태(b')를 표시하는 것을 포함하여 구성됨에 따라 모래시계 애니메이션을 통해 신호 변경에 소요되는 잔여시간을 알려줄 수 있도록 하는 것이 특징이다.
