摘要： 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.

摘要： An light bulb includes a bulb housing, a heat sink, and a head housing arranged in series along a longitudinal axis of the light bulb. The light bulb includes a first filament having a first LED chip capable of emitting a first light with a first color characteristic, and a second filament having a second LED chip capable of emitting a second light with a second color characteristic. The first filament and the second filament are spiral along a transverse axis perpendicular to the longitudinal axis of the light bulb. The light bulb further includes a driving module configured to enable one or a combination of the first filament and the second filament to emit light.

摘要： A method for installing a LED light bar into a light bulb. First, place a light module into bulb shell. The light bar module has a plurality of LED light bars and expansion structure. The expansion structure is unexpanded and disposed between the plurality of LED light bars. Each LED light bar has a certain bending property. Expending the expansion structure could make the plurality of LED light bars bent to the direction of bulb shell individually. And then, remove the expansion module and install the other components of the bulb.

摘要： Disclosed herein is a filament bulb with uniform luminance, which decreases the dark area at the top portion of the filament bulb and increases the luminance efficiency, and includes the following components, a bulb casing, a filament unit, a reflector ring, a driver, and a bulb cap. The bulb casing is connected with the bulb cap, and together, the two define an interior space. The driver is disposed in the bulb cap, whereas the filament unit is disposed within the interior space and the bottom of the filament unit is electrically connected with the driver. The reflector ring surrounds the exterior of the bottom of the filament unit, and is configured to reflect the light emitted from the filament unit to decrease the dark area at the top portion of the filament bulb.
