Abstract (en)

[origin: WO2009036978A1] An illumination unit is specified comprising (i) at least one light source, (ii) a detection unit on the basis of which at least a brightness of an image can be detected, (iii) at least one control unit which is connected to the at least one light source and to the detection unit, wherein the at least one light source can be driven by the control unit as a function of the at least one brightness of the image; (iv) a plurality of light sources, whose brightnesses can each be set individually and/or in clusters by the control unit; and (v) at least one switch, which can be used to short-circuit at least one light source. A method is also specified for driving the illumination unit.
