摘要:
Driver arrangements (1) comprise division circuits (100) with division inputs (101-102) for receiving input signals and division outputs (111-118) for supplying output signals to light sources (301-308). The division circuits (100) convert respective first and second input signals of a plurality of input signals into respective first and second parts of a further plurality of output signals. The driver arrangements (1) further comprise driver circuits (200) for driving the light sources (301-308) via the division circuits (100). The driver circuits (200) have driver outputs (201-202) for supplying the input signals to the division inputs (101-102). Such driver arrangements (1) no longer require a switch per light source (301-308). The plurality is preferably equal to or larger than two and smaller than the further plurality, and at least some of the first and the second parts are mutually different in size, amplitude or absolute value. The driver circuits (200) comprise controllable couplers (221-222) or controllable sources (211-212).
