Abstract (en)
[origin: WO9102441A1] The invention relates to a process and a circuit arrangement for adapting the light intensity of the summation light (Ei) of a room lit by internal light (Ek) and external light (Ei') to the external light (Ea), which varies with the time of day. The light intensity of the internal light is controlled in function of one or more control parameters in accordance with a given function which can be varied according to individual sensitivity. To obtain finer adjustment of the adaptation of the light intensity in a room, the function is determined by a plurality of independently adjustable function values (11) and each function value (11) can be varied independently of the other function values (11).
