  • Patent number: 11262027
    Abstract: A light bulb apparatus includes a head cup, a bottom support, multiple light strips and a bulb shell. The head cup is connected to an external power source. The bottom support is extended from the head cup. Each light strip has a top end and a bottom end. The bottom ends of the light strips are connected to the bottom support. The top ends of the light strips form a top polygonal shape and the bottom ends of the light strips form a bottom polygonal shape. The bottom polygonal shape has a bigger area size than the top polygonal shape. Each light strip has a skewed angle with respect to a middle axis perpendicular to the bottom shape.
