摘要： Provided is a vehicle lamp for emitting illumination light having reduced color nonuniformity and luminance variation with a simple structure. The vehicle lamp comprises: a light source for emitting excitation light; a fluorescent body for emitting fluorescent light excited by the excitation light emitted from the light source; a diffuser for diffusing the excitation light specularly reflected on the surface of the fluorescent body; and a reflector for reflecting the fluorescent light emitted from the fluorescent body and the excitation light diffused by the diffuser ahead of a vehicle. The fluorescent body is arranged above the light source, and the reflection surface of the reflector is arranged to face the fluorescent body from the direction in which the light is specularly reflected on the fluorescent body toward the lower side of the fluorescent body.

摘要： A vehicular lighting apparatus is relatively small, low cost, superior in mountability, and offers a superior design. The vehicular lighting apparatus attachable to a front end of a vehicle 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 illumination 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.

摘要： Provided is a vehicular lighting apparatus which is relatively small, can be manufactured at low cost, is superior in mountability to an automobile, and is superior in recognizeability of an object illuminated by a head lamp. The vehicular lighting apparatus attachable to a front end part of a vehicle 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 illumination 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. The light-emitting element emits whit light including red light.

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.
