Abstract

Official abstract text for this publication.

A method for manufacturing a light-emitting device may include producing a support having at least one conductor track on a surface of the support. The method may further include producing a reflective coating directly on the at least one conductor track by means of a film transfer method such that the conductor track is substantially covered by the reflective coating and arranging a light-emitting component on or above the reflective coating. The light-emitting component may be electrically conductively connected to the conductor track(s).

First claim

Opening claim text (preview).

The invention claimed is: 1. A method for manufacturing a light-emitting device, the method comprising: forming a carrier with at least one conductor track on a surface of the carrier; forming a reflective coating directly on the at least one conductor track by a film transfer method in such a way that the conductor track is substantially covered by the reflective coating; and arranging a light-emitting component on or over the reflective coating, wherein the light-emitting component is electrically conductively connected to the at least one conductor track. 2. The method as claimed in claim 1 , further comprising forming at least one contact pad on the surface of the carrier, said at least one contact pad being electrically conductively connected to the at least one conductor track, and wherein the reflective coating is formed on or over the contact pad in such a way that the contact pad is at least partially exposed. 3. The method as claimed in claim 1 , wherein the reflective coating is formed as a solder barrier structure for the contact pad. 4. The method as claimed in claim 3 , wherein the light-emitting component is electrically conductively connected to the at least one conductor track by the contact pad. 5. The method as claimed in claim 3 , wherein a soldered connection is formed between the light-emitting component and the contact pad. 6. The method as claimed in claim 1 , wherein the carrier comprises at least one first conductor track and a second conductor track electrically insulated from the at least one first conductor track, and wherein the reflective coating comprises a first section formed directly on the first conductor track, and comprises a second section formed directly on the second conductor track, wherein the first section is electrically insulated from the second section. 7. The method as claimed in claim 1 , wherein the reflective coating is electrically conductive. 8. The method as claimed in claim 1 , wherein the reflective coating is electrically nonconductive. 9. The method as claimed in claim 1 , wherein the reflective coating is applied on or over the carrier by a cold film transfer method. 10. The method as claimed in claim 1 , wherein the reflective coating is applied on or over the carrier by a hot film transfer method. 11. The method as claimed in claim 1 , wherein the reflective coating comprises an electrically conductive material. 12. The method as claimed in claim 1 , wherein the reflective coating comprises an electrically nonconductive material.
