Lighting device for a motor vehicle

A lighting device for arrangement on the external or internal rear view mirror of a motor vehicle, the lighting device comprising:

• a light source, wherein said light source is arranged in a tube at a first axial end;
• a transparent light refraction element;
• a mirror housing with an opening, the light rays of said light source emerging at said mirror housing opening and are deflected at said transparent light refraction element arranged in the beam path;
• a Fresnel prism plate-like light refraction element having a surface structure on one side dividing said Fresnel prism plate-like light refraction element into several light reaction zones, the light refraction zones corrersponding to prism zones of a prism body which are pushed together in stepwise manner;
• a condenser lens arranged in the beam path in front of the Fresnel prism, wherein an optical center line of said condenser lens runs parallel off center with respect to an optical center line of the lighting device;
• a diaphragm, which interrupts the beam path in a regionwise manner, arranged in the beam path behind the Fresnel prism;
• and
• a reflector wherein said tube absorbs light rays which do not impinge directly on the Fresnel prism, the condenser lens or the reflector, wherein said tube absorbs light rays which do not impinge directly on the Fresnel prism, the condenser lens or the reflector, said material for producing the tube consists of an infrared-transparent basic component which is provided with a dye, the dye absorbing visible light and being transparent to infrared radiation.

A lighting device for arrangement on the external or internal rear view mirror of a motor vehicle, the lighting device comprising:

• a light source, wherein said light source is arranged in a tube at a first axial end of which a reflector is arranged and at the opposite end of which the generated light beam may emerge;
• a transparent light refraction element;
• a mirror housing with an opening, the light rays of said light source emerging at said mirror housing opening and are deflected at said transparent light refraction element arranged in the beam path;
• a Fresnel prism plate-like light refraction element having a surface structure on one side dividing said Fresnel prism plate-like light refraction element into several light refraction zones, the light refraction zones corresponding to prism zones of a prism body which are pushed together in stepwise manner;
• and
• a condenser lens arranged in the beam path in front of the Fresnel prism, wherein an optical center line of said condenser lens runs parallel off center with respect to an optical center line of the lighting device;
• and
• a diaphragm, which interrupts the beam path in a regionwise manner, arranged in the beam path behind the Fresnel prism.
