Optoelectronic semiconductor chip, optoelectronic semiconductor component, and a method for producing an optoelectronic semiconductor component
Abstract:
An optoelectronic semiconductor chip includes a semiconductor body that emits primary light, and a luminescence conversion element that emits secondary light by wavelength conversion of at least part of the primary light, wherein the luminescence conversion element has a first lamina fixed to a first partial region of an outer surface of the semiconductor body, the outer surface emitting primary light, and leaves free a second partial region of the outer surface, the luminescence conversion element has a second lamina fixed to a surface of the first lamina facing away from the semiconductor body and spaced apart from the semiconductor body, the first lamina is at least partly transmissive to the primary radiation, a section of the second lamina covers at least the second partial region, and at least the section of the second lamina is designed to be absorbent and/or reflective and/or scattering for the primary radiation.
