ABSTRACT:
A light bulb apparatus mounted within existing incandescent bulb sockets is comprised of a plurality of interconnecting printed circuit boards (PCBs). An outline shape of any individual PCB is defined in essentially two dimensions a shape or a size of which may vary from one PCB to another. A first portion of this apparatus is equivalent to light bulb cap and is shaped and sized to be fitted into a conventional incandescent bulb socket. At this portion, at least three PCB side edges are lined up against with an inner side wall of a bulb socket. At least one PCB has a tip edge. A second portion of this apparatus is equivalent to a conventional bulb's glass bulb, and a plurality of light emitting devices are mounted on surfaces of the said PCBs and are connected to the circuit laid on boards.
