Abstract

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-emitting surfaces and the LED elements is relatively long, and can improve the luminance uniformity on the light exit surfaces.
