Abstract

To avoid clock signals and to separate power wiring from control wiring in a driver and to avoid three terminal light emitting diodes with control electrodes a driver for driving light emitting diode circuits (10 20 30) is provided with first and second terminals (1 2) for receiving a voltage signal from a source(5)and with a first switching circuit (11 2) coupled to the second terminal (2) and to a third terminal(3). The first and the third 5 terminal (1 3) are to be coupled to electrodes of a first light emitting diode circuit(10). The first switching circuit (11 12) comprises a first switch (11) and a first timing circuit (12) for in response to a first pulse signal as added to the voltage signal activating the first switch (11) to switch on the first light emitting diode circuit (10).Sequential pulse signals may be used to sequentially switch on light emitting diode circuits (10 20).
