  • Patent number: 11248783
    Abstract: The lighting apparatus has a wire box, a driver module, a light source and a light housing. The wire box is made of a heat dissipation material. The wire box is for placing a portion of an external wire. The driver module electrically connects to an electrode of the portion of the external wire. The light housing has a top cover and a surrounding wall. The top cover and the surrounding wall form a container space. The top cover has an inner side and an exterior side. The light source is thermally and structurally connected to the inner side for emitting a light via a light opening of the container space. The wire box is connected to the top cover of the light housing. Heat of the light source is transmitted to the wire box for heat dissipation via the back cover.

  • Patent number: 10473291
    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.

  • Patent number: 10344920
    Abstract: A lighting device includes a filament, a filament fixing element, a driving circuit, a lamp holder and a bulb shell. The filament has a long strip bottom, installed with a plurality of LED modules. The filament fixing element has a bearing surface and a heat dissipation part. The bearing surface connects to the long strip bottom of the filament. The heat dissipation part is connected to the bearing surface to dissipate the heat. The driving circuit provides a suitable current to the filament for emitting light. The lamp holder houses the drive circuit and carries the filament fixing element. The bulb shell and the lamp holder constitute an accommodating space for receiving the filament and the filament fixing element.
