First Claim
Patent Images
1. A method for housing multiple LEDs in a LED light bulb comprising:
- providing a transparent housing and a base;
providing a plurality of printed circuit boards having LEDs disposed substantially around peripheral edges of said plurality of printed circuit boards;
constructing a pyramidal structure of said plurality of printed circuit boards by stacking said plurality of printed circuit boards in layers, so that said plurality of printed circuit boards form a pyramidal structure such that said peripheral edges of adjacent printed circuit boards of said plurality of printed circuit boards do not extend substantially beyond the LEDs that are disposed around said peripheral edges of the plurality of printed circuit boards and do not substantially block light and heat emitted from the LEDs;
connecting said multiple printed circuit boards having said multiple LEDs with conductor wires.

Abstract
Disclosed is an LED light bulb having safe and efficient heat dissipation, while also providing maximum light distribution by providing multiple printed circuit boards arranged in a pyramidal structure, having multiple LEDs. The multiple printed circuit boards are connected by conductor wires contained within a transparent housing, so that the multiple printed circuit boards sit on a base of the LED light bulb. A bottom printed circuit board may also be employed if additional circuitry is desired.

3. An LED light bulb comprising:
-
at least two printed circuit boards arranged in a pyramidal structure so that an upper printed circuit board with at least one LED has a smaller surface area than a lower printed circuit board, said smaller printed circuit board having a peripheral edge that does not substantially block light and heat emitted from LEDs connected to said lower printed circuit board; a transparent housing that encloses said at least two printed circuit boards that are arranged in said pyramidal structure. - View Dependent Claims (4, 6)
