LED LIGHTING SYSTEM

摘要

A DC-powered LED lighting device and a lighting system using such devices are disclosed. A common AC/DC power supply is coupled to at least one electric main and provides power to the LED lighting devices at DC voltages that are higher than the peak voltage of the sine wave of the at least one electric main.

主权项

1. A light emitting diode (LED) lighting device, comprising:
a DC/DC converter adapted to convert electrical power at a first DC voltage V1 into electrical power at a second DC voltage V2; a LED driving circuit operably coupled to the DC/DC converter that is powered using electrical power from the DC/DC converter at the second DC voltage V2; and at least one LED assembly operably coupled to the LED driving circuit that is powered by the LED driving circuit.
