Abstract:
1. A vehicle lamp having an optical axis and a light emission direction extending along the optical axis, comprising: a light source; a reflector having both an inner surface and an outer surface, the light source located adjacent the reflector, and the inner surface of the reflector configured to reflect light emitted from the light source towards the light-emission direction of the vehicle lamp; a front lens configured to allow both light emitted from the light source and light reflected from the reflector to pass through; a casing configured in a tubular shape having both an inner surface and an outer surface, the casing being sealed between the front lens and the reflector; and a thermal conductive material configured to contact at least one of the outer surface of the reflector and the outer surface of the casing, and attached to at least one of the casing and the reflector, the thermal conductive material having a surface facing towards the light source, wherein a majority of the surface facing towards the light source contacts at least one of the casing and the reflector, and the at least one of the outer surface of the reflector and the outer surface of the casing which is configured to contact the thermal conductive material is formed as a V-shaped groove in cross-section when viewed in a direction perpendicular to the optical axis, the V-shaped groove enlarging as the groove approaches the reflector.
