Abstract
A semiconductor light source emits a light. The semiconductor light source is directly mounted on a heat sink unit. A swivel unit swivels the semiconductor light source and the heat sink unit. A swivel shaft that is coupled to the swivel unit is integrated with the heat sink unit.
Claims9
A vehicle lamp comprising:
- a semiconductor light source that emits a light;
- a heat sink unit on which the semiconductor light source is directly mounted;
- a reflector with an opened upper portion and an opened lower portion that forms a space with an upper opening and a lower opening;
- and
- a swivel unit that swivels the semiconductor light source and the heat sink unit, wherein
- a swivel shaft that is coupled to the swivel unit is integrated with the heat sink unit,
- the reflector is separately disposed from the heat sink unit, and
- the heat sink unit includes a rear radiation portion which extends rearward from a rear side of the heat sink unit into the space,
- the semiconductor light source is directly mounted on an upper portion of the heat sink unit,
- a shape of the heat sink unit is a turntable rotating around the swivel shaft in a top plane view, and
- the heat sink unit is disposed in a lamp chamber that houses the semiconductor light source.
