  • Patent number: 10247364
    Abstract: 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.

  • Publication number: 20180306407
    Abstract: 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.

  • Publication number: 20180238499
    Abstract: A method of installing a light emitting diode light bar into a bulb is provided. Place the light bar module into the light bulb shell. The light bar module has a plurality of light emitting diode light bars and an expansion structure. The expansion structure is not expanded and is disposed among multiple light emitting diode light bars. Each light emitting diode light bar has a certain degree of flexibility. Expanding the expansion structure then, therefore multiple light emitting diode light bars are individually bent and deformed toward the bulb shell direction. Next, remove the expansion module and install other components of the bulb.
