Abstract
A periphery of a projecting lens is heated due to radiation heat exerted by light emitted from a light source, like peripheries of the light source and a reflector. However, a lens holder holding the projecting lens is integrally molded with a heat sink member, so that a heat at the periphery of the projecting lens is well transmitted to the heat sink member by means of the lens holder, and is efficiently radiated by means of the heat sink member.
