Light-emitting diode carrier
View Patent ↗In a light-emitting diode carrier 1 , a plurality of light-emitting diodes 9 are mounted on the rear side 3 of the light-emitting diode carrier and project into a plurality of openings 2 . During operation, the light-emitting diodes 9 radiate through the openings 2 of the light-emitting diode carrier 1 . A film 10 is applied on the front side 4 of the light-emitting diode carrier 1 , said film being transmissive to the radiation emitted by the light-emitting diodes and protecting the light-emitting diode carrier from ambient influences.
1. A light-emitting diode carrier having a plurality of light-emitting diodes, wherein the light-emitting diode carrier comprises a circuit board that has a substantially planar front face at a front side, a substantially planar rear face, opposite from the front face, at a rear side and a plurality of openings, extending from the rear face to the front face, the plurality of light-emitting diodes being arranged on the rear side of the light-emitting diode carrier so that at least a portion of the light-emitting diodes extends into the openings and the light emitting diodes radiate toward the front side of the light-emitting diode carrier, and wherein the light-emitting diodes are electrically connected on the rear side of the light-emitting diode carrier and do not extend beyond the front side of the carrier.
2. The light-emitting diode carrier as claimed in claim 1 , wherein side walls of the openings have a reflective surface.
3. The light-emitting diode carrier as claimed in claim 1 , wherein the openings expand toward the front side of the light-emitting diode carrier.
4. The light-emitting diode carrier as claimed in claim 1 , wherein the openings expand conically toward the front side of the light-emitting diode carrier.
5. The light-emitting diode carrier as claimed in claim 1 , wherein a film which is transmissive to the radiation emitted by the light-emitting diodes is arranged on a front side of the light-emitting diode carrier.
6. The light-emitting diode carrier as claimed in claim 1 , wherein a lens array is arranged on the front side of the light-emitting diode carrier in such a way that a lens of the lens array is arranged above a respective opening.
7. The light-emitting diode carrier as claimed in claim 6 , wherein the lens array is reversibly arranged such that it can be repositioned based on the desired radiation characteristic.
8. The light-emitting diode carrier as claimed in claim 6 , wherein each light-emitting diode is assigned to an individual lens of the lens array.
9. The light-emitting diode carrier as claimed in claim 1 , wherein the light-emitting diode carrier is formed in radiation-absorbing fashion on the front side.
10. The light-emitting diode carrier as claimed in claim 1 , wherein the light-emitting diode carrier is colored black on the front side or is colored with a different color in order to set a desired contrast.
11. The light-emitting diode carrier as claimed in claim 1 , wherein the light-emitting diodes are electrically connected to conductor tracks on the rear side of the light-emitting diode carrier.
12. The light emitting diode carrier as claimed in claim 1 wherein the light-emitting diode carrier is a solid body.
13. The light emitting diode carrier as claimed in claim 1 wherein the light-emitting diode carrier is a printed circuit board.
