LASER LIGHT-SOURCE APPARATUS AND PROJECTOR APPARATUS

摘要

PROBLEM TO BE SOLVED: To achieve a laser light-source apparatus that keeps the temperature of a light-emitting part at a constant level even if laser output is high and stabilizes the output and emission wavelength of a laser beam, and a projector apparatus.

SOLUTION: The laser light-source apparatus has: a laser driving circuit board 20; a heat-insulating material 51 installed on the laser driving circuit board 20; a heat-receiving plate 31 installed on the heat-insulating material 51 and thermally separated from the laser driving circuit board 20; a laser light-source module 10 that is placed on the heat-receiving plate 31 so as to be thermally connected with the heat-receiving plate 31 and is driven while being electrically connected with the laser driving circuit board 20; and a heat sink 32 thermally connected with the heat-receiving plate 31 via a heat pipe 33.
