HEAT SINK FOR LIGHTING AND LIGHTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a heat sink for lighting which is formed into a small shape preventing weight increase of a lighting device and has a heat radiation performance that deals with large luminous energy of the lighting device, and to provide the lighting device using the heat sink.SOLUTION: A heat sink for lighting includes: a base part 10 which thermally contacts with a heat source; a heat radiation fin 11 erected on the base part 10; and a heat conductive member 12 which is provided on a heat radiation surface 11a of the heat radiation fin 11 and has heat conductivity higher than that of the heat radiation fin 11. The heat conductive member 12 is formed so as to have an area smaller than the heat radiation surface 11a of the heat radiation fin 11. One end of the heat conductive member 12 is positioned at a base end part 11b of the heat radiation fin 11 and the other end is positioned at a tip part 11c of the heat radiation fin 11.
