<P>PROBLEM TO BE SOLVED: To provide a heat radiation structure of a vehicle lamp unit capable of preventing melting of a separator due to heat. <P>SOLUTION: As a heat radiation structure of a vehicle lamp unit which has a heat sink 11 having a plurality of radiation fins 11B, a plurality of LEDs (light-emitting element) 13 installed on the heat sink 11 and mounted on a substrate 12, and a separator 14 which is arranged in the vicinity of the LEDs 13 and splits individually light from the LEDs 13, a heat radiation member 15 is installed on at least a surface of the separator 14 which receives light from the LEDs 13. The heat radiation member 15 is constituted of a metal plate, or as the heat radiation member 15, a paint having a high thermal conductivity is applied on at least the surface of the separator 14 for receiving the light from the LEDs 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
