A vehicle lighting device is provided which is capable of merely changing a shade, thereby using a first reflector and a second reflector as they are, to cope with a variety of light distribution pattern specifications, and which is capable of avoiding deformation of a shade due to a thermal effect even if incidence of sunlight going back has optically focused on the shade. In a heat sink member 40, there are arranged: a semiconductor-type light source 10; a first reflector 21 covering the semiconductor-type light source 10 therewith; a second reflector 22 for causing the reflected light from the first reflector 21 so as to be made incident thereto and then reflecting the incident light forward of the lighting device; and a shade 30 for shading a part of the reflected light from the first reflector 21 so as to be made incident to the second reflector 22. The shade 30 is configured as another member independent of the first and second reflectors 21, 22, and is arranged in the heat sink 40.

An SSL lighting device (1) comprising a housing (2), which has a reflective inner surface (3), and an elongated light guide (6) which includes a wavelength converting material (10) for converting light in a first wavelength range to light in a second wavelength range. The elongated light guide (6) comprises two ends (7a, 7b), a portion for receiving light (18) and a portion for emitting light (19). The portion for receiving light (18) is arranged inside the housing (2) and the portion for emitting light (19) is arranged outside the housing (2) and at least one of the two ends (7a, 7b) forms the portion (19) for emitting light. The SSL lighting device (1) also comprises a plurality of SSL light sources (4) arranged inside the housing (2) at a distance from the elongated light guide (6). A part of the light emitted from the plurality of SSL light sources (4) into the housing (2) enters the light guide (6) via the portion for receiving light (18) and is absorbed and converted by the wavelength converting material (10). By enclosing the light sources (4) and a portion of the light guide (6) inside a housing (2) with a reflective inner surface (3) and by having a wavelength conversion process occurring inside the light guide (6), this construction enables light from several light sources (4) to be used for providing a single high-intensity and high-power light source.

A lighting unit comprises a solid state lighting element (10). An upper housing (18) forms a light mixing chamber (20) over the solid state lighting element (10) and a loop-shaped antenna (22) is held by the upper housing (18), wherein the upper housing (18) comprises a reflective inner wall at least where it defines the mixing chamber (20) and said solid state lighting element (10) is inside said reflective inner wall. This makes use of the component which defines the mixing chamber (20) to hold a loop-shaped antenna (22) in place above the lighting element (10) and therefore away from the heat generated by the lighting element (10) and away from any metallic heat sink or heat spreading components (16).
