<p>A headlight for a vehicle is provided to form a unit driving source of each alternation equipment in a compact structure by using a sub lamp unit for changing/forming a pattern as an operation structure. A main lamp unit is fixed to a lamp body(11) through only an aiming mechanism. The first sub lamp unit(19) comprises a semiconductor light-emitting device as a light source, a reflector(27), a projection lens(29), a diffusion filter(31), a top/bottom alternation equipment(33), a right/left alternation equipment(35) and a pattern changing equipment(37). The semiconductor light-emitting device is a white light-emitting diode having a light-emitting chip. A heat sink(50) efficiently radiates the heat from the semiconductor light-emitting device. The reflector attached to a base member(30) has a reflective surface for reflecting the light of light-emitting device toward an optical axis.</p> |
