SEMICONDUCTOR TYPE LIGHT SOURCE UNIT OF VEHICLE LAMP FITTING AND VEHICLE LAMP FITTING

摘要

PROBLEM TO BE SOLVED: To provide a semiconductor light source unit which simplifies a mold structure (a mold drawing structure) of a socket part and achieves low manufacturing costs.SOLUTION: A light source part includes: a substrate 3 bent into a first mounting surface 31 and a second mounting surface 32; and semiconductor light emitting elements 40 to 44 mounted on the first mounting surface 31. A socket part 11 includes: a heat radiation member 8 serving as an attachment member to which the light source part is attached; and a power supply member which is attached to the heat radiation member so as to be arranged in parallel or substantially parallel with the first mounting surface 31 and is electrically attached to the second mounting surface 32.
