Abstract

An illumination device is disclosed, comprising a support (1) and a number of light modules (21, 22) each with a number of radiating semiconductor components (311, 312, 313, 314, 321, 322, 323, 324) in several rows (411, 412, 421, 422). Each one of the several rows (411, 412, 421, 422) comprises at least two of the radiating semiconductor components (311, 312, 313, 314, 321, 322, 323, 324). Each one of the number of light modules (21, 22) is provided with a regulating device (51, 52) for regulating the brightness of the light module (21, 22). Each one of the number of light modules (21, 22) is provided with a sensor device (61, 62) for determining at least one measured value comprising the brightness of the number of radiating semiconductor components (311, 312, 313, 314, 321, 322, 323, 324). An illumination device is further disclosed, comprising a support (1), a number of light modules (21, 22, 23), a number of radiating semiconductor components (311, 312, 313, 314, 321, 322, 323, 324) and a heat-regulating device.
