Abstract
A vehicle lamp can include a light source, a reflector and a lens. The reflector can be formed in a slender shape so as to include a parabolic reflex surface in a longitudinal direction and an ellipsoidal reflex surface in a direction substantially perpendicular to the longitudinal direction. A focus of the parabolic reflex surface and one of the focuses of the ellipsoidal reflex surface can be located at the light source, and other focuses of the ellipsoidal reflex surface can be substantially parallel with a central axis of the lens. The reflector can reflect light emitted from the light source toward the lens with a wide angle so that light use efficiency of the light source can improve as compared with certain conventional vehicle lamps. Thus, the vehicle lamp can provide a favorable light distribution even when it is formed in a slender shape.
