Document Type and Number:
WIPO Patent Application WO/2022/071432
Kind Code:
A1
Abstract:
Provided is a lighting fixture for a vehicle which efficiently releases heat from a light source while inhibiting moisture from entering on the light source side. This lighting fixture (10) for a vehicle comprises: a light source (21); a heat dissipating member (22) which dissipates heat from the light source (21), with the light source (21) being placed on an installation surface (43); and a socket (23) to which the heat dissipating member (22) is attached. The heat dissipating member (22) has a heat dissipating fin part (42) protruding from a heat dissipating surface (44) on the side opposite from the installation surface (43), and a heat dissipating-side positioning part (positioning projection (53)) provided to the heat dissipating surface (44). The socket (23) has, on an attachment surface (63) facing the heat dissipating surface (44), a fin recess (66) into which the heat dissipating fin part (42) fits, and a socket-side positioning part (positioning hole (68)) which determines the positional relationship between the heat dissipating member (22) and the socket (23) in cooperation with the heat dissipating-side positioning part.
