PROBLEM TO BE SOLVED: To provide an LED headlamp for vehicle with high waterproof properties at a part where a heat sink penetrates a headlamp case, and that, capable of surely and effectively radiating heat of LEDs toward outside the case.SOLUTION: A headlamp is provided with a fixed heat sink 14 fixed to a headlamp case, and a movable heat sink 23 supported by the fixed heat sink 14 in free swinging in an up-and-down direction. It is provided with a first LED 17 fitted on the fixed heat sink 14, and a second LED fitted to the movable heat sink 23 so as to irradiate light in an up-and-down direction contrary to the first LED 17. It is also provided with a first parabolic mirror reflector 31 as well as a second parabolic mirror reflector 32 fitted on the movable heat sink 23. An optical axis adjustment mechanism swings an assembly consisting of the movable heat sink 23, the second LED, and the first and second parabolic mirror reflectors 31, 32 in an up-and-down direction against the fixed heat sink 14. |
