Abstract

An assembly for emitting light including a circuit board, an LED for producing a light, wherein the LED is arranged on the circuit board, an optical element, which is arranged in such a way that the optical element optically influences the light produced by the LED, and a spacing element, wherein the spacing element is arranged between the optical element and the circuit board.

First claim

The invention claimed is:

1. An assembly for emitting light, comprising:
a circuit board,
an LED for generating a light, wherein the LED is arranged on the circuit board,
an optical element, which is arranged in such a way that it optically influences the light generated by the LED, and
a spacer element consists of ceramic material, wherein the spacer element is arranged between the optical element and the circuit board, the spacer element establishing a distance δ between the circuit board and the optical element which is smaller than a structural height of the LED above the circuit board,
wherein the optical element is retained on the spacer element.

2. The assembly as claimed in claim 1 , wherein the spacer element is formed by an electrical or electronic component which is a surface mounted on the circuit board.

3. The assembly as claimed in claim 1 , wherein the optical element is a lens element.

4. The assembly as claimed in claim 3 , wherein the optical element is formed by a lens, a lens array, a lens plate or a plastic optical plate.

5. The assembly as claimed in claim 1 , wherein the optical element is produced using injection molding technology or by extrusion.

6. The assembly as claimed in claim 1 , furthermore comprising at least one further LED for generating a further light, wherein the optical element is arranged in such a way that it also optically influences the further light generated by the at least one further LED.

7. The assembly as claimed in claim 1 , wherein the spacer element is configured as a positioning aid element for positioning the optical element relative to the LED and/or relative to the circuit board.

8. The assembly as claimed in claim 7 , wherein the spacer element is embodied as a positioning aid element for securing a position of the optical element relative to the LED and/or to the circuit board.

9. An assembly for emitting light, comprising:
a circuit board,
an LED for generating a light, wherein the LED is arranged on the circuit board,
an optical element, which is arranged in such a way that it optically influences the light generated by the LED, and
a spacer element arranged between the optical element and the circuit board;
wherein the spacer element is formed by a zero ohm resistor.

10. The assembly as claimed in claim 9 , wherein the spacer element is arranged directly on the circuit board.

11. The assembly as claimed in claim 10 , wherein an LED module having an integrated height positioning for the optical element is formed by the circuit board, the LED and the spacer element.

12. An assembly for emitting light, comprising:
a circuit board,
an LED for generating a light, wherein the LED is arranged on the circuit board,
an optical element, which is arranged in such a way that it optically influences the light generated by the LED, and
a spacer element, wherein the spacer element is arranged between the optical element and the circuit board, the spacer element establishing a distance δ between the circuit board and the optical element which is smaller than a structural height of the LED above the circuit board,
wherein the optical element is connected directly to the spacer element.

13. The assembly as claimed in claim 12 , wherein the spacer element is configured as a positioning aid element for positioning the optical element relative to the LED and/or relative to the circuit board.

14. An assembly for emitting light, comprising:
a circuit board,
an LED for generating a light, wherein the LED is arranged on the circuit board,
an optical element, which is arranged in such a way that it optically influences the light generated by the LED, and
a spacer element, wherein the spacer element is arranged between the optical element and the circuit board and is formed by an electrical or electronic component;
wherein the spacer element is formed by a zero ohm resistor.

15. The assembly as claimed in claim 14 , wherein the spacer element is arranged directly on the circuit board.

16. The assembly as claimed in claim 14 , wherein the optical element is a lens element.
