<P>PROBLEM TO BE SOLVED: To provide a lighting system capable of efficiently radiating heat from a heat-generating part, in one capable of efficiently radiating heat generated in a power supply circuit section. <P>SOLUTION: The lighting system includes a light source module 1, the power supply circuit section 7 in which a transformer 721 is mounted on a power supply board 71, and the heat radiation part 2 radiating heat generated in the power supply circuit section 7. The transformer 721 is provided so that a lower voltage side terminal is set on an edge side of the power supply board 71. Since the heat radiation part 2 can be put in close proximity to the transformer 721, heat radiation can be certainly made by efficiently transmitting the heat generated in the transformer 721 to the heat radiation part 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
