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.
