Abstract

An optoelectronic semiconductor device includes a first light source that emits green, white or white-green light and includes a semiconductor chip that emits in the blue spectral range, and a first conversion element attached directly to the semiconductor chip, a second light source that emits red light, having a semiconductor chip, that emits in a blue spectral range, and having a second conversion element attached directly to the semiconductor chip, and/or having a semiconductor chip that emits in a red spectral range, a third light source that emits blue light and has a semiconductor chip emitting in the blue spectral range, and a filler body having a matrix material into which a conversion agent is embedded, wherein the filler body is disposed downstream of the light sources collectively.
