PROBLEM TO BE SOLVED: To provide a vehicle lamp fitting which efficiently cools a semiconductor light emitting element without being affected by hot air generated by engine cooling.SOLUTION: A lamp body part 100 and a light source part 200 serving as a light emitting part are integrated by an optical fiber 300. The light source part 200 includes a heat sink 201 provided at a housing 101 of the lamp body part 100. The heat sink 201 comprises: a base part 201a which fits in the housing 101; and heat radiation fins 201b coupled to a lower part of the base part 201a. A semiconductor light emitting element 202 and a temperature sensor 203 are mounted on the base part 201a of the heat sink 201. The heat radiation fins 201b are embedded in blast tubes 205, 206. The heat radiation fins 201b are provided so as to close the blast tubes 205, 206. A damper 208 is provided at the upstream side of the heat sink 201 in the blast tube 205, and a ventilation axial flow fan 210 is provided at the upstream side of the heat sink 201. |
