Abstract
A housing defines at least a part of a lamp chamber therein, and includes an opening; a light source disposed in the lamp chamber. An optical unit is disposed in the lamp chamber, and irradiates light emitted from the lamp source in a predetermined direction. A heat sink includes a first portion configured to support the light source in the lamp chamber, and a second portion exposed to an outside of the housing through the opening. An elastic member is disposed between the second portion and a periphery of the opening. A first screw member and a second screw member extend through the housing, and are manually rotated to displace both the heat sink and the optical unit with respect to the housing. An electric actuator is disposed in the lamp chamber, and displaces the optical unit with respect to the heat sink.
