WIPO Patent Application WO/2023/176506
Kind Code:
A1
Abstract:
The purpose of the present invention is to solve the problem of uncured coating when a shade for forming a cut-off line of a lamp is formed by stacking two plates. To achieve the purpose, a lamp unit (100) comprises: light sources (411-416); a projection lens (10); and a plate-like shade (60) that is disposed on the rear focal point (f) of the projection lens (10) and that controls light emitted from the light sources (411-416). The shade (60) has, to form a cut-off line, a first plate (61) having a step (63), in which one plate surface is protruded and the other plate surface is recessed, and a second plate (62) which reinforces the first plate and which is overlapped on the first plate. The second plate (62) has a non-overlapping region (65) not overlapping at least a part of the step (63) of the first plate (61) in the direction of overlapping with the first plate (61).
