<P>PROBLEM TO BE SOLVED: To provide an illuminating device that effectively dissipates heat by rapidly conducting the heat generated from an exotherm component mounted in a drive circuit which drives a light source of the illuminating device to a heat dissipating part. <P>SOLUTION: In the illuminating device that has: a driving circuit 3 which drives a light source module 1 and mounts exotherm components 31a such as IC; and a heat dissipating part 4 which dissipates heat from the exotherm components 31a and has a housing 45 to house the driving circuit 3 in the interior, the driving circuit 3 is housed in the housing 45 by making the exotherm components 31a, 31a, 31a close to the heat dissipating part 4. Thus, the heat generated from the exotherm components 31a is rapidly conducted to the adjacent heat dissipating part 4, and heat dissipation from the heat dissipating part 4 can be carried out efficiently. <P>COPYRIGHT: (C)2011,JPO&INPIT |
