Abstract (en)

[origin: WO2016099579A2] A high efficiency LED light fixture and power supply designed to maximize system life while doubling electrical efficiency relative to existing LED light systems. The LED efficiency is addressed by operating near the lower end of the LED power rating. At these values the LED chip efficiency is maximum. The longevity is addressed by using a high efficiency cross flow heat sink to significantly lower the LED temperature to within 10 degrees C above ambient conditions. The system uses a 1200 watt power supply to improve the AC to DC efficiency of the system allowing multiple LED troffers to be powered from a single power supply.
