  • Dual-use light fixture having AC and DC LEDs
    Patent number: 9052068
    Abstract: A dual-use light fixture having AC and DC LEDs includes a heat-dissipating housing, a printed circuit board located on a first end of the heat-dissipating housing, AC and DC LED chips located on the printed circuit board, and a power supply pedestal coupled to a second end of the heat-dissipating housing. The power supply pedestal includes an AC plug, a DC driving unit, and a thread connector. The AC plug is electrically connected to the printed circuit board for inserting into an AC outlet to provide an AC power. The DC driving unit is located in an accommodating space formed by the power supply pedestal and the heat-dissipating housing and is electrically connected to the printed circuit board. The thread connector is coupled to another AC power, and the AC power is converted into a DC power by the DC driving unit.
