摘要： A light emission arrangement includes a driver arrangement having a first, a second, and a third driver. The light emission arrangement also includes a number N of assemblies. Each assembly includes a first, a second, and a third light-emitting semiconductor body. The number N is greater than 1. The first driver is coupled to a first series connection including the first light-emitting semiconductor bodies of the number N of assemblies. The second driver is coupled to a second series connection including the second light emitting-semiconductor bodies of the number N of assemblies. The third driver is coupled to a third series connection including the third light-emitting semiconductor bodies of the number N of assemblies. The first, second, and third driver are each configured to output a driver signal dependent on photometric quantities of the first, the second, and the third light-emitting semiconductor bodies of the number N of assemblies.

摘要： An optoelectronic module includes a control element, at least one temperature sensor, and at least one semiconductor emitter unit. The semiconductor emitter unit includes at least a first emitter and a second emitter. The first emitter is intended to emit electromagnetic radiation in a first wavelength range. The second emitter is intended to emit electromagnetic radiation in a second wavelength range different from the first wavelength range. The control element includes a memory unit and a driver output for each emitter. The temperature sensor determines a temperature. Each emitter is assigned a non-linear characteristic curve in the memory unit. The control element is intended to drive the emitters independently of each other by means of a respective driver output. The control element controls the emitters depending on the determined temperature and the respective characteristic curve of the emitter.
