Beschreibung
Zusammenfassung:	An LED lighting assembly (1) comprising a cassette (2), a lens, a printed circuit board, PCB, (6) having at least one LED light source mounted thereon, the lighting assembly comprising an LED driver circuit arranged to maintain conduction in the circuit, the PCB using a first amount of power and wherein the LED driver circuit is arranged to simulate use of a second amount of power, the second amount being lower than the first amount. The LED lighting assembly comprises a capacitor arranged to be activated when a voltage across the LED driver circuit is below a first predetermined level. A resistor or resistor/capacitor combination is connectable to a trickle sensor in a passenger service unit (PSU).
