Abstract:
1. A vehicle light configured as a projector-type optical unit and configured to emit light in a forward light emitting direction comprising: a semiconductor light emitting device; a reflector located adjacent the semiconductor light emitting device such that light emitted from the semiconductor light emitting device is reflected by the reflector in the forward light emitting direction; a convex projection lens configured to project light that is at least one of light emitted directly from the light emitting device and light that is reflected by the reflector, in the forward light emitting direction, the lens including a rear side focus; a shutter located adjacent the rear side focus of the projection lens, wherein a sealed space including at least an inner surface of the reflector that is located adjacent the semiconductor light emitting device is hermetically sealed from an exterior atmosphere; a sealing member configured to hermetically seal the sealed space from the exterior atmosphere; and an air pressure adjusting bag made of a film-like material and located adjacent the sealed space in order to adjust air pressure in the sealed space.
