Abstract
The invention relates to an optoelectronic component (100) having a semiconductor chip (2) for generating a primary radiation in the blue spectral range, a conversion element (4) which is arranged in the beam path of the semiconductor chip and is designed to generate a secondary radiation from the primary radiation, wherein the conversion element (4) comprises at least one first phosphor (9) and a second phosphor (10), wherein the first phosphor (9) is Sr(Sr1−xCax)Si2Al2N6:Eu2+ and/or (Sr1−yCay)[LiAl3N4]:Eu2+, where 0≤x≤1 and 0≤y≤1, wherein a total radiation (G) exiting from the component (100) is white mixed light.
