Patent ID: 7528556

Claim:
A light regulation device having at least one light sensor ( 10 ), which provides an actual value for a brightness at its output, at least one regulator ( 22 a to 22 d ), to which a desired value for the brightness is supplied, in addition to this actual value, a number n of output connections ( 24 a to 24 d ), where n is greater than or equal to two, each output connection ( 24 a to 24 d ) being coupled to the output of a regulator ( 22 a to 22 d ) for the purpose of changing a luminous flux which can be supplied in each case to at least one luminous means ( 18 a to 18 d ), the regulator ( 22 a to 22 d ) being designed to determine a difference between the desired value and the actual value and to check whether this difference is within or outside a predeterminable tolerance range and, for the case in which the difference is outside the tolerance range, to change the luminous flux of the luminous means ( 18 a to 18 d ), which are connected to the n output connections ( 24 a to 24 d ), in a corresponding manner; characterized in that at least one limit of the tolerance range depends on a present value for the luminous flux.
