Abstract:
1. A driver for driving a light generator for generating light, comprising a digital-to-analog converter (DAC) having a data input, a data output for generating an analog signal, characterized in that the driver further comprises a first multiplexer (MUX 1 ) for cyclic selection of a number of data levels corresponding to desired intensity levels of the light and for coupling the data levels to the data input; a de-multiplexer (DE-MUX) synchronized with the first multiplexer (MUX 1 ) for de-multiplexing the analog signal into a set of analog signals; memory means for temporarily storing the set of analog signals; and a second multiplexer (MUX 2 ) for selection of the stored set of analog signals and for generating a drive signal (I L ) for the light generator.
