  • LED filament light bulb apparatus
    Patent number: 11118739
    Abstract: A flexible filament light bulb apparatus includes a first power wire, a second power wire, a first LED filament, a second LED filament, and a driver. A first end of the first LED filament is connected to the first power electrode. A fourth end of the second LED filament is connected to a second power electrode. The second end of the first LED filament is connected to the third end of the second LED filament. A driver is used for converting an external power source to a driving current supplied to the first power electrode and the second power electrode.

  • LED light apparatus
    Patent number: 10912168
    Abstract: A LED light apparatus includes a central beam module, a peripheral light module, a support housing and a cap. The central beam module has a beam lens for converting a first light to form a light beam. The peripheral light module has a light passing ring. The light passing ring surrounds the beam lens for converting a second light to form a peripheral light. The peripheral light has a lower intensity strength than the light beam. The support housing fixes the central beam module and the peripheral light module. The cap is fixed to the support housing for plugging in an external socket for getting an external power supply.
