Patent ID: 8419250

Claim:
A vehicle headlamp including: a light source section for emitting light accompanied by heat; a heat pipe thermally connected with the light source section, for absorbing and transferring the heat generated by the light source section; a heat radiating member provided in a position deviated from the optical axis of the light generated by the light source section and closer to a front of the headlamp than the light source section to be thermally connected to the heat pipe, for radiating the heat transferred from the heat pipe to produce a convection current; and a headlamp case housing the light source section, the heat pipe, and the heat radiating member, and having provided on the upper side of the heat radiating member a portion of a front lens for passing the light from the light source section, wherein the heat radiating member has at least one extending fin arranged such that heat transferred to the heat radiating member produces an ascending gas current on a front side of the interior of the headlamp case generating convection such that the ascending current hits the front lens, cools the front lens producing a descending gas current.
