Abstract:
1. A light-emitting diode (LED) module, having at least one blue LED and a color conversion layer applied thereto, which module emits a mixed light from the spectrum of light of the LED and the converted spectrum of the color conversion layer, wherein the color conversion layer has at least three different phosphors, which convert the light of the blue LED at least partially into red, green, and yellow or yellow-green light, the phosphor for conversion into red light is a doped nitride compound, the phosphor for conversion into green light is a europium-doped alkaline earth orthosilicate, the percentage proportion of alkaline earth orthosilicate in the color conversion layer is from 10 percent to 50 percent, the phosphor for conversion into yellow or yellow-green light is a doped yttrium aluminum garnet (YAG) phosphor, wherein the percentage proportion of phosphor based on nitride in the color conversion layer is from 10 percent to 30 percent, and wherein the percentage proportion of phosphor based on YAG in the color conversion layer is from 20 percent to 41 percent.
