IPC: H05B44/00
Filed: 2005-03-31
Abstract: A light regulation device comprises at least one light sensor (10) which provides at its output a real brightness value, at least one regulator (22a to 22d) to which a set brightness value can be supplied, besides said real value, and a number n of output connections (24a to 24d), n being greater than or equal to two. Each output connection (24a to 24d) is coupled to the output of a regulator (22a to 22d) in order to modify the light flux which can be supplied to at least one of the lighting means (18a to 18d). The regulator (22a to 22d) is designed to determine a difference between set and real values, to verify whether this difference lies within or outside a predeterminable tolerance range, and, in the event that the difference lies outside the tolerance range, to modify accordingly the light flux from the lighting means (18a to 18d) which can be connected to the n output connections (24a to 24d). At least one limit of the tolerance range depends on the actual light flux value.
