Abstract

A lighting module (1), comprising a circuit board (2) equipped with at least one light source:, (3) and a hollow light guide element (4; 31; 33) which laterally surrounds the circumference of the at least one light source (3) and extends forward beyond the at least one light source (3), wherein an inner face (4a; 32; 34) of the light guide element (4; 31; 33) is at least partially reflective and a front-side opening of the light guide element (4; 31; 33) corresponds to a light emission opening (L) of the lighting module (1).

Claims

1. A lighting module, comprising:

a circuit board equipped with at least one light source; and

a hollow light guide element which laterally surrounds the circumference of the at least one light source and extends forward beyond the at least one light source,

wherein an inner face of the light guide element is at least partially reflective and a front-side opening of the light guide element corresponds to a light emission opening of the lighting module.

2. The lighting module as claimed in claim 1, wherein a plane of the light emission opening is parallel to a plane of the at least one light-emitting diode.

3. The lighting module as claimed in claim 1, wherein the light guide element has an essentially hollow cylindrical basic form.

4. The lighting module as claimed in claim 1, wherein the light guide element comprises an electrically nonconducting material.

5. The lighting module as claimed in claim 1, having at least one receiving means for receiving an attachment element by way of the light emission opening.

6. The lighting module as claimed in claim 5, wherein the receiving means is designed as a fastening interface.

7. The lighting module as claimed in claim 1, wherein the lighting module has a cover for at least some of the electronic components disposed on the front face of the circuit board, and wherein a front face of the cover essentially lies in the plane of the light emission opening.

8. The lighting module as claimed in claim 1, wherein the light guide element is laterally surrounded at least in sections of the circumference by a ring-shaped cover for at least some of the electronic components disposed on the front face of the circuit board.

9. The lighting module as claimed in claim 1, wherein the light guide element affords a direct access to the at least one light source through the light emission opening.

10. The lighting module as claimed in claim 1, wherein the light guide element has an inner face which widens towards the front

11. The lighting module as claimed in claim 1, wherein the light guide element has an inner face which narrows towards the front.

12. The lighting module as claimed in claim 1, wherein the inner face of the light guide element has an optically active surface structure.

13. The lighting module (1) as claimed in claim 12, wherein the surface structure has a wave structure.

14. The lighting module as claimed in claim 12, wherein the surface structure has a roughened surface.

15. The lighting module as claimed in claim 1, wherein the inner face of the light guide element is colored at least in some areas.

16. The lighting module as claimed in claim 1, wherein said at least one light source is a light-emitting diode.
