  • Patent number: 11828423
    Abstract: A light bulb apparatus includes a bracket, a flexible light strip, a bulb shell, a central base and a driver. The bracket includes a central bar and multiple top hooks. The multiple top hooks have first ends connected to the central bar. The flexible light strip has multiple first bending points fixed to second ends of the multiple top hooks for expanding the flexible light strip. a bulb shell. A driver for converting an external power source to a driving current. The central base encloses a part of two wires. The central base exposes first electrodes of the two wires for connecting to the flexible light strip. The central base exposes second electrodes of the two wires for receiving the driving current. The central base and the bulb shell form a closed space for holding the flexible light strip and the bracket.

  • Publication number: 20210372574
    Abstract: A light bulb apparatus includes a central column, a first metal strip, a second metal strip, multiple elongated filaments and a bulb shell. The central column is made of glass material. The central column has a top part, a tubular part and a trumpet part. The first metal strip has a first bracket part exposed outside the top part of the central column and bent as a first half bottom bracket. The second metal strip has a second bracket part exposed outside the top part of the central column and bent as a second half bottom bracket. The first half bottom bracket and the second half bottom bracket form a bottom bracket. The multiple elongated filaments have bottom ends fixed to the bottom bracket.

  • Patent number: 11118738
    Abstract: A light bulb apparatus includes a central column, a central bar, a top bracket, a bottom bracket, multiple elongated filaments and a bulb shell. The central column is made of glass material. The central column has a top part, a tubular part and a trumpet part. The top part and the trumpet part are located at two opposite ends of the tubular part. The central bar is extended from the central column upwardly. The top bracket has a limiting structure to limit a movement of the top bracket relative to the central bar. The bottom bracket is fixed to the central column. The multiple elongated filaments have bottom ends fixed to the bottom bracket and with top ends fixed to the top bracket. The bulb shell has a bottom edge fixed to the trumpet part forming a container space enclosing the bottom bracket and the multiple elongated filaments.

  • Patent number: 11112064
    Abstract: A light apparatus with an enlightened pattern includes a driver circuit, a LED plate, an optical light guide, a connector and a bulb shell. The LED plate connected to the driver circuit has a LED module for emitting a light. The optical light guide has a bottom end facing to the LED module for receiving the light and has a top end forming an enlightened pattern where the light escaped from the top end of the optical light guide. The connector is used for fixing the LED plate to the optical light guide for aligning the LED module to emit the light into the bottom end and for transmitting heat of the LED plate to the optical light guide.
