Controllers (1) control generators (2) arranged to generate frequency signals for controlling converters (3) in drivers for driving light circuits (5). The controllers comprise first parts (11) for in response to feed-back information from the light circuits (5) produce control signals arranged to control the generators (2) and second parts (12) for in response to data information adapting the control signals. The data information comprises codes for coding light produced by the light circuits (5). The feed-back information may comprise values of feed-back signals flowing through the light circuits (5) or defining light intensities of the light circuits (5). The control signals may define frequencies of the frequency signals. Third parts (13) may determine a static transfer of converter-light circuit-combinations defined by values of the feed-back signals and corresponding values of the frequencies. The corresponding values of the frequencies may form a first axis, the values of the feed-back signals may form a second axis. Fourth parts (14) may define default transfers of the combinations. The controllers (1) may be self-learning-controllers. |
