Abstract

An optoelectronic semiconductor component having a light source, which emits primary radiation, a housing, and electrical terminals, wherein a conversion element, which is based on a matrix and at least two phosphors, is connected upstream of the optoelectronic semiconductor component. The matrix contains metal phosphate and preferably consists of metal phosphate. The phosphors partially or completely convert primary radiation. At least one first phosphor powder is embedded and fixed in a first inorganic matrix based on a metal phosphate, and at least one second phosphor powder is embedded and fixed in a second matrix based on a metal phosphate.
