摘要： A vehicle lamp includes a phosphor which receives laser light (excitation light) emitted from a semiconductor light-emitting element to emit visible light, a reflector which reflects the visible light (illumination light) emitted from the phosphor forward, and an absorbing member which absorbs excitation light regularly reflected by a surface of the phosphor. A metal plate on which the phosphor is disposed to be inclined to cause the excitation light regularly reflected by the surface of the phosphor to be incident on the absorbing member. An upper end portion of the reflector is disposed at a position lower than a vertical position of the phosphor to prevent the regularly reflected excitation light from being incident on the upper end portion.

摘要： A vehicular lighting apparatus which is relatively small, low cost, superior in mountability to an automobile, and superior in recognizeability of an object illuminated by a head lamp. The apparatus includes: a composite lens element that is a light guide element constructed by molding a translucent resin substantially into a plate-like shape; a planar light-emitting unit that emits light; an optical system that transforms planar light from the light-emitting unit into linear light and that causes the linear transformed light to be incident on a rear side face of the light guide element; and a diffraction lens formed on the rear side face of the light guide element on which the linear transformed light is incident, and condensing the linear transformed light. The light condensed by the lens means is emitted from a front side face of the light guide element onto a road surface in front of the vehicle.
