PURPOSE:To provide vehicle lamp equipment which has its reflection plane prevented from discoloration and deterioration without using other parts. CONSTITUTION:High heat conductivity material is contained in an undercoat 8. A high heat conductivity film 9 is provided at least either between a reflection film 6 and an undercoat 5 or between the undercoat 5 and a reflector 1. As a result, when heat ray from a bulb 4 reaches the undercoats 5, 8 locally, heat is transferred from local areas in the undercoats 5, 8 and the reflector 1 to all areas via the high heat conductivity material in the undercoat 8 and the high heat conductivity film 9 adjacent to the undercoat 5. It is thus possible to prevent the localization of the heated section of a reflection plane 12 and discoloration and deterioration of the reflection plane 12 without using other parts such as a thermal shielding plate. |
