The invention relates to a composite, comprising a ceramic converter for converting light having a first wavelength into light having a second wavelength, a metal-containing, reflective coating and a heat sink. The surface of the ceramic converter is at least partly coated with the metal-containing, reflective coating, wherein the coating dissipates the heat from the converter into the heat sink. The heat sink and the metal-containing, reflective coating are connected to one another by means of a metallic soldering connection. Furthermore, the invention relates to a method for producing a composite, comprising a ceramic converter, a metal-containing, reflective coating and a heat sink, comprising the following method steps: a) providing a ceramic converter having at least one polished surface, b) providing a paste, containing a metal powder and an organic paste fluid, c) applying the paste to at least one part of the polished converter surface, d) drying the paste, e) firing the paste at temperatures >450°C, and f) connecting the heat sink to the fired paste by soldering using a metallic solder. |
