FIELD: physics. ^ SUBSTANCE: lighting system includes a drive current controller which outputs current signals for one or more first groups of light-emitting elements, and a signal output module operatively connected to the drive current controller. The signal output module is configured to determine drive current signals for one or more second groups of light-emitting elements. The current signals are based on current signals output into the first group of light-emitting elements. The method comprises steps for determining one or more first drive currents for driving one or more first groups of light-emitting elements and determining one or more second groups of drive currents for driving one or more second groups of light-emitting elements, wherein each of the one or more second drive currents is predetermined based on at least one of the one or more first drive currents. ^ EFFECT: simplification and higher cost-effectiveness. ^ 15 cl, 2 dwg |
