Abstract

An LED module has a carrier, which contains a semiconductor layer and has a planar main area, on which LED semiconductor bodies are applied. Use is preferably made of LED semiconductor bodies which emit light of differing central wavelengths during operation, so that the LED module is suitable for generating mixed-color light, and in particular for generating white light.
