The present invention relates to a crosswalk lighting system installed to illuminate a crosswalk, which comprises: a lighting body mounted on a pillar installed around a crosswalk; a main light emitting module in which a plurality of unit light emitting elements having a pair of a first light emitting diode having a warm color temperature and a second light emitting diode having a cool color temperature different from that of the first light emitting diode are arrayed to be spaced from each other on one surface facing the crosswalk on the lighting body; an external environment information sensing unit for collecting external environment information including illuminance and weather; and a control unit for controlling driving of the main light emitting module using the environment information received from the external environment information sensing unit, and adjusting and driving a light emitting ratio of the first and second light emitting diodes in accordance with the weather and set adjustment conditions. According to the crosswalk lighting system of the present invention, a pedestrian accident can be reduced by adjusting a color temperature to irradiate light having a wavelength which has visually high recognition efficiency in accordance with a change in weather, and a jaywalking attempt can be reduced by notifying a waiting time of a crosswalk traffic light.

    본 발명은 횡단보도를 조명할 수 있도록 설치되는 횡단보도 조명 시스템에 관한 것으로서, 횡단보도 주변에 설치된 지주에 장착된 조명 본체와, 조명 본체 상의 횡단보도와 대향되는 일면에 웜색온도를 갖는 제1발광다이오드와, 제1발광다이오드와 색온도가 다른 쿨색온도를 갖는 제2발광다이오드가 상호 쌍을 이룬 단위 발광요소가 상호 이격되게 다수 어레이된 메인 발광모듈과, 조도와 날씨를 포함한 외부 환경정보를 수집하는 외부 환경정보센싱부와, 외부 환경정보센싱부로부터 수신된 환경정보를 이용하여 메인 발광모듈의 구동을 제어하되 날씨에 따라 제1발광다이오드와 제2발광다이오드의 발광비율을 설정된 조정조건에 따라 조정하여 구동하는 제어유니트를 구비한다. 이러한 횡단보도 조명 시스템에 의하면, 날씨 변화에 따라 시각적으로 인지 효율이 높은 파장의 광을 조사하도록 색온도를 조정함으로써 보행자 사고를 줄일 수 있고, 횡단보도 신호등의 대기시간을 알려줌으로써 무단횡단시도를 줄일 수 있는 장점을 제공한다.
