Abstract

A pixel light source includes having a light source array, an optical system and an imager matrix arrangement, wherein the optical system maps light radiated by the light source array onto the imager matrix arrangement, the light source array includes a plurality of light emitting diode elements and a plurality of LARP elements, and the optical system is configured to map the light radiated by at least one of the LARP elements into a gap in the angular aperture situated between the light radiated by the light emitting diode elements.

Claims (22)

1. A pixel light source comprising:

a light source array, an optical system and an imager matrix arrangement,

wherein the optical system maps light radiated by the light source array onto the imager matrix arrangement,

the light source array comprises a plurality of light emitting diode elements and a plurality of LARP elements, and

the optical system is configured to map the light radiated by at least one of the LARP elements into a gap in the angular aperture situated between the light radiated by the light emitting diode elements.

2. The pixel light source according to claim 1 , wherein the LARP elements are arranged between the light emitting diode elements.

3. The pixel light source according to claim 1 , wherein the light emitting diode elements are arranged in a hexagonal pattern.

4. The pixel light source according to claim 1 , wherein the LARP elements are arranged in a hexagonal pattern.

5. The pixel light source according to claim 1 ,

wherein the LARP elements are arranged between the light emitting diode elements,

the light emitting diode elements are arranged in a hexagonal pattern,

the LARP elements are arranged in a hexagonal pattern, and

the hexagonal pattern of the light emitting diode elements and the hexagonal pattern of the LARP elements overlap.

6. The pixel light source according to claim 1 ,

wherein the optical system maps the light radiated by the light source array onto the imager matrix arrangement with a first extent, measured in a first direction, of the angular aperture and a second extent, measured in a second direction, of the angular aperture,

the first direction and the second direction are oriented at right angles to one another, and

the first extent of the angular aperture and the second extent of the angular aperture are of different magnitude.

7. The pixel light source according to claim 1 , wherein at least one LARP element is configured such that light radiated by the LARP element and mapped onto the imager matrix arrangement by the optical system comprises an intensity that falls from a middle of the imager matrix arrangement to an edge region of the imager matrix arrangement.

8. The pixel light source according to claim 1 , wherein the optical system comprises a plurality of optical lenses.

9. The pixel light source according to claim 1 , wherein the optical system comprises a field lens.

10. The pixel light source according to claim 1 , wherein the imager matrix arrangement is configured as a micromirror matrix arrangement.

11. A headlamp for a motor vehicle comprising the pixel light source according to claim 1 .
