Abstract:
A light guiding device for vehicle lighting system includes a tube having a serrated surface composed of a plurality of segment surfaces and a reflection member is located beside the serrated surface at a distance. A light source is connected with the tube and emits light beams. The light beams are refracted by the segment surfaces and some of the light beams reflected by the segment surfaces due to narrow input angles will be reflected by the reflection member and travels toward the tube so that the head light has an even illumination with less dark area.
