description A driving circuit 1400 for driving a light source 1412 comprising a plurality of light-emitting diodes LED1, LED2, includes a power converter 1410 and a dimming controller 1408. The converter, coupled to a power source VIN, 306, receives power from the power source and provides regulated power to the light source according to control signals 1450 and 1452. The dimming controller, coupled to the converter, is operable for monitoring operation of a power switch 1404 coupled between the power source and the converter, for receiving a colour change signal indicated by a first set of operations of the power switch and a dimming request signal indicated by a second set of operations of the power switch, for controlling the control signals to change the colour of the light source in response to the colour change signal, and for controlling the control signals to adjust the brightness of the light source in response to the dimming request signal. ­
