Abstract
A lighting controller and method has light sources which are activated for a respective lighting duration in a repeating non-overlapping sequence. The end of the lighting duration for one light source is detected for triggering the switching on of the next light source in the sequence. This provides non-overlapping control of the light sources and provides an efficient and easy to implement the required controller.
