Abstract: A light-emitting semiconductor component may include a conversion layer, a radiation surface, and a plurality of adjacently arranged emission regions configured to be operated separately, individually and/or in groups. The conversion layer may be arranged downstream of the emission regions in the direction of radiation of the emission regions. The emission regions may be configured to emit primary radiation of a first wavelength range into the conversion layer. The conversion layer may be configured to convert at least a portion of the primary radiation into secondary radiation of a second wavelength range. Mixed radiation is configured to be emitted from the light-emitting semiconductor component at the radiation surface. The mixed radiation may include primary radiation and secondary radiation. A probability that primary radiation travelling from the emission region to the radiation surface is converted into secondary radiation may vary along the radiation surface by a maximum factor of 2.

Abstract: An optoelectronic component may include at least one semiconductor chip for emitting electromagnetic radiation, a conversion element, and an optical element. The conversion element may at least partially convert primary radiation emitted by the semiconductor chip(s) into secondary radiation where the conversion element is arranged downstream of the semiconductor chip(s) in the emission direction and is arranged on the semiconductor chip(s). The optical element may be arranged downstream of the conversion element in the emission direction and where the conversion element is subdivided into individual portions.
