Light source comprising laser diode module

摘要

A light source is disclosed including at least one laser diode module (10) and a heat pipe (31) having a heat absorbing portion and a heat radiating portion. The laser diode module (10) includes a metal substrate (21) mounting a laser diode chip (11) and an optical component (12), and a peltier device (23) thermally connected with the metal substrate (21). The heat absorbing portion of the heat pipe (31) is thermally connected with the peltier device (23). The light source preferably includes a plurality of densely placed laser diode modules (10), each of which has an output of at least 100 mW. The light source also preferably includes a plurality of heat pipes (31) having heat radiating fins (32) on the heat radiating portions thereof. <IMAGE>
