Abstract
A method for controlling the operation of a lighting unit comprising a plurality of lighting elements and a dimmable power supply unit with an output for adjusting the brightness of at least some of the lighting elements. The method provides that for at least one dimmer setting at least one real electrical parameter is measured, as a function of the absorption of the lighting elements and that the measured electrical parameter is compared with at least one previously-stored theoretical value.
