Abstract
The purpose is to facilitate the adjustment of the size of a light emitting region of a lens structure. A lens structure for a vehicle light body includes a light emitting part and a base. The light emitting part includes an introduction reflective surface which causes light from the base to completely reflect as parallel light to the Z− direction, and a back-side reflective surface arranged to the Z direction in the light emitting back surface. Each back-side reflective surface has a normal direction sloping relative to the Z direction, and causes the parallel light from the introduction reflective surface to completely reflect to the Y+ direction. The light emitting surface emits light from the back-side reflective surface.
Claims6
A lens structure for a vehicle light body which causes light to emit in a Y+ direction as one way of a predetermined Y direction, the lens structure comprising:
- a light emitter extending in a Z direction orthogonal to the Y direction, and having a light emitting surface at an end face on a side of the Y+ direction, and a light emitting back surface at an end face in a Y− direction opposite the Y+ direction;
- and
- a base which guides light to an end of the light emitter in a Z+ direction as one way of the Z direction,
- wherein the light emitter includes an introduction reflective surface which causes light from the base to completely reflect as parallel light to a Z− direction which is opposite to the Z+ direction, and a back-side reflective surface arranged in the Z direction on the light emitting back surface,
- wherein each of the back-side reflective surfaces has a normal direction sloping relative to the Z direction, and completely reflects the parallel light from the introduction reflective surface to the Y+ direction, and
- wherein the light emitting surface causes light to emit from the back-side reflective surface.
