FLOOR-TYPE WALKING SIGNAL DEVICE
The present invention provides a floor-type walking signal device for installation in which the device is buried in the ground between a road and a sidewalk, comprising a reflector having a plurality of reflective surfaces respectively corresponding to a plurality of LED elements. The present invention can prevent the luminance from being lowered by using the reflector, even if the distance between light-exiting surfaces and the LED elements is relatively long, and can improve the luminance uniformity on the light exit surfaces.
La présente invention concerne un dispositif de signal de marche du type au sol pour une installation dans laquelle le dispositif est enfoui dans le sol entre une route et un trottoir, comprenant un réflecteur présentant une pluralité de surfaces réfléchissantes correspondant respectivement à une pluralité d'éléments de DEL. La présente invention peut empêcher la luminance d'être abaissée au moyen du réflecteur, même si la distance entre des surfaces de sortie de lumière et les éléments de DEL est relativement longue, et peut améliorer l'uniformité de luminance sur les surfaces de sortie de lumière.
본 발명은 차도와 인도 사이의 지면에 매립 설치하기 위한 바닥형 보행 신호 장치로서, 복수의 LED 소자 각각에 대응하는 복수의 반사면을 구비한 리플렉터를 포함한다. 본 발명은 상기 리플렉터를 이용하여 출광면과 LED 소자 사이의 거리가 상대적으로 더 길더라도 휘도가 낮아지지 않게 할 수 있고, 출광면에서의 휘도 균제도를 향상시킬 수 있다.
