Abstract:
An LED module comprising at least one blue LED and a color conversion layer that is applied thereto and emits a mixed light of the blue light of the LED and the converted spectrum of the color conversion layer. The color conversion layer has at least three different phosphors which at least partially convert the light of the blue LED into red, green, and yellow or yellowish-green light. The phosphor for conversion into red light is a doped nitride compound, preferably a nitridosilicate.
