Abstract
LED systems with a multi-channel direct current power supply unit. The system has a first circuit in electrical communication with a first channel of the power supply and a second circuit in electrical communication with a second channel of the power supply. The power supply provides a constant current to the first and second circuits. The system has a third circuit in electrical communication with the ground of the power supply. A plurality of driverless luminaires are connected in series wherein each driverless luminaire has a first LED array electrically connected in series to the first circuit and a second LED array electrically connected in series to the second circuit and a driverless luminaire ground electrically connected to the third circuit.
