VEHICULAR HEADLAMP, LIGHTING SYSTEM AND ITS HEAT RADIATION MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a heat radiation member having high heat radiation performance, and easily formable at low cost; a vehicular headlamp; and a lighting system.

SOLUTION: This heat radiation member 15 for an LED light source comprises: a base part 15a for thermally connecting a board 11a of the LED light source in order to radiate heat of the LED light source 11; and a plurality of thin plate-like radiation fins 15b projecting nearly in parallel to one another from the base part. The heat radiation member 15 is structured such that the base part 15a and the respective radiation fins 15b are formed separately from one another; the base part 15a is formed by forging or casting; and the respective radiation fins 15b are formed out of a thin plate material by bending work.
