PROBLEM TO BE SOLVED: To prevent a resin projection lens from being affected by heat generated in a semiconductor light source.SOLUTION: The invention includes: a semiconductor light source 2; a reflector 4; a projection lens 3; a heat sink member 5, and a heat insulation member 6. The projection lens 3 is made of a resin and is attached to the heat sink member 5 through the heat insulation member 6. As a result, the heat insulation member 6 prevents the resin projection lens 3 from being affected by heat generated in the semiconductor light source 2. |
