WIPO Patent Application WO/2023/234259
Kind Code:

Abstract:
The present invention is for emitting a light distribution pattern at suitable illuminance. This vehicle light-guiding body comprises: an incident surface on which light impinges from a light source; a first reflective surface that inwardly reflects the light impinged from the incident surface; a second reflective surface that inwardly reflects at least a portion of the light reflected by the first reflective surface toward the front so as to pass through the focal point or the vicinity of the focal point; a light-shielding part that shields a portion of the light reflected by the second reflective surface; an inner reflective surface that is positioned between the front end part of the second reflective surface and the light-shielding part, and that inwardly reflects a portion of the light inwardly reflected by the second reflective surface toward the front; an emission surface that emits the light inwardly reflected by the second reflective surface; and an adjustment unit that is provided in a part of the inner reflective surface that is behind the light-shielding part and closer to either the left or right than the focal point of the second reflective surface, and that inwardly reflects or refracts a portion of the light reflected by the second reflective surface to emit it to the outside from a part that is different from the emission surface.
