WIPO Patent Application WO/2023/171478
Kind Code:
A1
Abstract:
The purpose of the present invention is to prevent a reflector from rotating during assembly in a lamp unit in which a light source substrate is co-clamped with the reflector. To achieve this, a lamp unit (100) comprises: a light source substrate (40) equipped with a light source (42); a reflector (30) that reflects light from the light source; and a fixing portion (50) to which the light source substrate and the reflector are fixed. The light source substrate (40) is sandwiched between the reflector (30) and the fixing portion (50). The reflector (30) is positioned with respect to the light source substrate (40) by a positioning portion (34) that positions the reflector (30) with respect to the light source substrate (40), and is fixed to the fixing portion (50) by fasteners (36) on both sides of the reflector in the longitudinal direction. The reflector (30) has a rotation restraint portion (38) having a shape protruding in the direction in which the fixing portion (50) is located. The rotation restraint portion (38) is formed further outward than the positioning portion (34).
