Abstract

A method for producing a lighting module is provided. The method includes providing a light source substrate populated with at least one semiconductor light source, laterally surrounding the at least one semiconductor light source by a wall, applying at least one prefabricated diffuser element to at least one semiconductor light source, introducing potting compound into the space surrounded by the wall up to a height at which both the at least one semiconductor light source, and potting at least part of the at least one diffuser element.

First claim

What is claimed is:

1. A method for producing a lighting module, the method comprising:
providing a light source substrate populated with at least one semiconductor light source;
laterally surrounding the at least one semiconductor light source by a wall, said wall being independent and detachable from the light source substrate;
applying at least one prefabricated diffuser element onto each of the at least one semiconductor light sources; and then thereafter
introducing a potting compound into the space surrounded by the wall, said wall molds the potting compound up to a height at which both the at least one semiconductor light source and at least part of the at least one diffuser element are potted;
wherein the space surrounded by the wall is potted with the potting compound up to an upper side of the at least one diffuser element.

2. The method of claim 1 ,
wherein the potting compound is low-viscosity.

3. The method of claim 2 ,
wherein the viscosity of the potting compound lies with a viscosity in a range of about 10 to 1000 mPa·s.

4. The method of claim 1 ,
wherein the at least one prefabricated diffuser element is adhesively attached to at least one semiconductor light source.

5. The method of claim 4 ,
wherein a high-viscosity adhesive with a viscosity of at least 100,000 mPa·s is used as a bonding agent.

6. The method of claim 1 ,
wherein the diffuser element is an extruded diffuser element.

7. The method of claim 1 ,
wherein the diffuser element is a multi-region body with at least one transparent region and at least one light-scattering region.

8. The method of claim 7 ,
wherein the transparent region is applied to the at least one semiconductor light source.

9. The method of claim 1 ,
wherein the potted light source substrate populated with at least one semiconductor light source and diffuser element is fabricated.

10. The method of claim 9 ,
wherein the populated light source substrate is a panel.

11. The method of claim 1 ,
wherein the potting compound is formed as reflective.

12. The method of claim 11 ,
wherein a white pigment is added to the potting compound.

13. A lighting module, comprising:
a light source substrate, which is populated with at least one semiconductor light source;
a wall, wherein the wall is independent and detachable from the light source substrate; and
at least one diffuser volume, which is arranged at a light-exiting area of each of the at least one semiconductor light sources;
wherein the at least one semiconductor light source and at least part of the at least one diffuser volume are laterally potted with a potting compound up to an upperside of the at least one diffuser volume;
wherein the potting compound volume is contained within the arrangement of the wall and the at least one diffuser volume;
wherein the lighting module has been produced by a method, the method comprising:
providing the light source substrate populated with at least one semiconductor light source;
laterally surrounding the at least one semiconductor light source by the wall, said wall being independent and detachable from the light source substrate;
applying at least one prefabricated diffuser element onto each of the at least one semiconductor light sources; and then thereafter
introducing the potting compound into the space surrounded by the wall, said wall molds the potting compound up to a height at which both the at least one semiconductor light source and at least part of the at least one diffuser element are potted;
wherein the space surrounded by the wall is potted with the potting compound up to an upper side of the at least one diffuser element; and

wherein the at least one diffuser volume represents at least part of a prefabricated diffuser element.

14. The lighting module of claim 13 ,
wherein the lighting module is a light strip.

15. The lighting module of claim 13 , wherein the each of the at least one diffuser element are comprised of differing profile-like diffuser elements.

16. A method for producing a plurality of singular lighting modules, the method comprising:
providing a light source substrate populated with a plurality of semiconductor light sources;
laterally surrounding the plurality of semiconductor light sources by a wall, said wall being independent and detachable from the light source substrate;
applying at least one prefabricated diffuser element onto each of the plurality of semiconductor light sources;
introducing a potting compound into the space surrounded by the wall, said wall molds the potting compound up to a height at which both the plurality of semiconductor light sources and at least part of the at least one diffuser elements are potted;
wherein the space surrounded by the wall is potted with the potting compound up to an upper side of the at least one diffuser element; and
separating the singular lighting modules using at least one separating cutter,
wherein the separating cutter cuts through the potting compound between the at least two semiconductor light sources.

17. The method according to claim 16 , wherein the potting compound is separated in the form of strips parallel to the at least one diffuser element.

18. The method according to claim 16 , further comprising detaching the light source substrate and the wall using the detachable feature of said wall.

19. The method according to claim 16 , wherein the singular lighting module is a light strip comprised of a plurality of semiconductor light sources.

20. The method according to claim 16 , wherein the singular lighting module is comprised of a single semiconductor light source.
