Patent ID: 6909377

Claim:
An illumination device with light emitting diodes (LEDs) comprising: an LED support element, on which a large number of light pixels that emit light are arranged, whereby the light pixels are comprised of a plurality of LEDs that have different emission wavelengths suitable for additive color mixing of light emitted by the light pixels; a controller associated with the LED support element, wherein the controller pre-sets a color temperature parameter and an intensity parameter for the additively color mixed light emitted by each individual light pixel, whereby the controller assigns the electrical LED currents corresponding to the pre-set color temperature and intensity parameters and controls the LEDs of the light pixels with the LED currents assigned, regulation means that measures the color temperature and intensity of the emitted light of at least one light pixel of the LED support element, and wherein the regulation means compares the measured color temperature and intensity parameters with the pre-set color temperature and intensity parameters of the at least one light pixel, and wherein the regulation means stabilizes the emitted light of the at least one light pixel by means of the controller in response to deviations of the measured color temperature and/or intensity parameters from the pre-set color temperature and intensity parameters such that the emitted light of the at least one light pixel has the pre-set color temperature and intensity parameters.
