Abstract
The invention relates to an optoelectronic component (100) comprising a semiconductor chip (1) for generating a primary beam in the blue spectral range, a conversion element (4) which is arranged in the beam path of the semiconductor chip (2) and is designed to generate a secondary beam from the primary beam, wherein the conversion element (4) comprises at least one first luminescent material (9) used as a conversion material, the first luminescent material (9) being (La1-xCax)3Si6(N1-yOy)11:Ce3+ with 0≤x≤1 and 0<y≤1, wherein a total beam (G) emerging from the component (100) is white mixed light.
