ABSTRACT:
A vehicle light that includes a semiconductor light emitting device can have a simple structure which suppresses deterioration of the light emitting quality of the device. The vehicle light can be configured to prevent aging and/or deterioration of components, such as a vapor deposited silver coating on the reflection surface of a reflector of the light. The vehicle light can also include a projector type optical unit that has the following components: a semiconductor light emitting device; a reflector which surrounds the semiconductor light emitting device from a rear side such that light emitted from the semiconductor light emitting device is reflected in a forward direction; and a projection lens which projects light being directly from the light emitting device or after reflected by the reflector in the forward direction. Furthermore, a space around the semiconductor light emitting device of the optical unit can be hermetically sealed from the outside atmosphere. A sealing member can be used to form the sealed space.
