Abstract
In at least one embodiment, the optoelectronic semiconductor chip includes a semiconductor layer sequence having an active layer configured to generate a primary radiation having a main wavelength less than 500 nm. The semiconductor chip contains a first conversion element configured to generate a first secondary radiation and a second conversion element configured to generate a second secondary radiation. The semiconductor layer sequence is divided into segments that can be controlled electrically independently of each other and that are arranged laterally adjacent to each other. The conversion elements are attached to main radiation sides of the segments. The first secondary radiation is colored light and the second secondary radiation white light.
