Abstract:
The invention refers to a light emitting device including a semiconductor chip having a main radiation surface, which emits UV light in operation, a phosphor, which is arranged in the radiation beam of the UV light, absorbs partially the UV light, wherein the phosphor converts the UV light into visible light so that the device emits mixed light comprising the UV light as well as visible light.
