Abstract:
1. A polychromatic light emitting semiconductor chip for mounting into a housing for a light-emitting diode, comprising: a semiconductor body comprising a layer sequence suitable for emitting electromagnetic radiation of a first wavelength range selected from a spectral region consisting of ultraviolet, blue, and green; a luminescence conversion layer applied directly to said semiconductor body with at least one luminescent material, said luminescence conversion material being suitable for converting a radiation originating from the first wavelength range into radiation of a second wavelength range which is at least partially different from the first wavelength range, such that the semiconductor chip is capable of emitting polychromatic radiation comprising perceptible amounts of radiation of the first wavelength range and perceptible amounts of radiation of the second wavelength range.
