<P>PROBLEM TO BE SOLVED: To radiate efficiently heat generated from a semiconductor light-emitting element. <P>SOLUTION: A lighting fixture for a vehicle comprises an LED as a light source, a plurality of flat plate fins installed on a base part, and a plurality of ventilation paths formed between the flat plate fins, and has a heat sink 14 which radiates heat generated from the LED, air suction ports 56a, 56b in axial direction which sucks air, and a left side exhaust port 56c and a right side exhaust port 56d which respectively exhaust air in the left and right direction vertical to the axial direction and further, is provided with a centrifugal fan 56 which flows air into the ventilation paths of the heat sink 14 and forcibly air cools the flat plate fins and a lamp body which houses the LED, the heat sink 14, and the centrifugal fan 56. The flat plate fins of the heat sink 14 are formed so that the entrance of at least one ventilation path may face the left side exhaust port 56c and the right side exhaust port 56d of the centrifugal fan 56. <P>COPYRIGHT: (C)2010,JPO&INPIT |
