Lighting device for a motor vehicle with lens holder
The invention relates to a lighting device for a motor vehicle. The lighting device includes an imaging component having an active surface on which light-emitting diodes or laser diodes are arranged in a matrix-like manner for the targeted generation of pixels of a light distribution. The lighting device also includes projection optics. The projection optics are configured to project the light emanating from the active surface to the exterior of the motor vehicle during operation of the lighting device. The projection optics includes at least a first lens, a second lens, and a third lens. The lighting device also includes a lens holder, wherein the lens holder is suitable and configured to hold at least the third lens. The lighting device also includes a holding means, wherein the holding means is suitable and configured to hold the first lens and the second lens.
1 . A lighting device for a motor vehicle, the lighting device comprising:
an imaging component having an active surface on which light-emitting diodes or laser diodes are arranged in a matrix for a targeted generation of pixels of a light distribution;
projection optics, the projection optics being configured to project light emanating from the active surface toward an exterior of the motor vehicle, the projection optics comprising a first lens, a second lens, and a third lens, wherein the light emanating from the active surface first passes through the third lens, then through the second lens, and then through the first lens; and
a lens holder, wherein the lens holder is suitable and configured to hold at least the third lens, wherein the lighting device comprises a holding means, wherein the holding means is configured to hold the first lens and the second lens;
wherein the holding means has first recesses for fastening the first lens on a side of the holding means facing away from the imaging component; and
wherein the holding means has second recesses for fastening the second lens on a side of the holding means facing the imaging component.
2 . The lighting device of claim 1 , wherein the imaging component is a solid-state LED array.
3 . The lighting device of claim 1 , wherein the holding means is a one-piece component and is cup-shaped.
4 . The lighting device of claim 1 , wherein the holding means is disposed between the first lens and the second lens.
5 . The lighting device of claim 1 , wherein the holding means is configured as an aperture diaphragm, wherein the aperture diaphragm is configured to limit light projected by the projection optics toward the exterior of the motor vehicle.
6 . The lighting device of claim 1 , wherein the third lens is configured to produce light with an approximately parallel beam path, such that the third lens is configured as a collimator.
7 . The lighting device of claim 1 , further including a heat sink arranged on the imaging component.
8 . The lighting device of claim 1 , wherein the holding means includes positioning elements for fastening a diaphragm.
9 . The lighting device of claim 1 , wherein the holding means is a plastic injection-molded component formed of a thermoset or thermoplastic material.
10 . A motor vehicle comprising the lighting device of claim 1 .
