Abstract
A flyback converter is provided with a first output associated with a first secondary winding, a primary side controller arranged to maintain the first output at a predetermined voltage level and a second output associated with a second secondary windings; an LED controller. A first secondary electronically controlled switch is responsive to the LED controller; a first LED luminaire arranged to provide a first illumination responsive to a power signal on the second output when the first secondary electronically controlled switch is in a closed state and not provide the first illumination when the first secondary electronically controlled switch is in the open state, wherein the turns ratio of the first secondary winding and the second secondary winding is such that power is delivered to the first output via the first unidirectional electronic valve only when the first secondary electronically controlled switch is switched to the open state.
