ABSTRACT:
An array of light-emitting diodes in LED chips, which can be turned on and off individually or in groups by means of a circuit, is provided with a device for homogenizing a light beam emitted by the turned-on LED chips. This device can be a conversion plate, a potting compound comprising a converter material or scattering particles, or a device for beam shaping comprising a plurality of micro-optics. The light source is particularly suited for headlights, for example in AFS applications.
