Method of producing LED lighting apparatus and apparatus produced thereby
First Claim
1. A method of forming a bulb comprising a plurality of Light Emitting Diodes (LEDs), the method comprising:
- forming a printed circuit board including a plurality of LED panels having electrical connections therebetween;
mounting the plurality of LED devices, respectively, to the plurality of panels;
bending the printed circuit board into a three-dimensional shape;
inserting a main driving circuit within a longitudinal support;
coupling the main driving circuit to the printed circuit board through a tab extending from the main driving circuit;
aligning the printed circuit board to the tab;
mechanically supporting the printed circuit board with the tab; and
mounting the shaped printed circuit board and the longitudinal support into the bulb.

Abstract
Disclosed is an LED bulb having many advantages over previous bulbs. The bulb is designed with ease of fabrication and low cost in mind. A main support is made of chromed copper, used for both its reflectivity, its readily availability, and its relative low cost. A collection of bright LEDs are electrically coupled to a driving circuit formed on a board that is housed within the main support. The LEDs are mounted on a circuit board flexible enough to form into a desired shape while rigid enough to withstand normal movements. The LED circuit board includes multiple polished or shiny areas, also called lands or panels made to reflect light away from the bulb. The panels are electrically insulated from the operating circuit and prevent injury should the bulb be broken and the components be touched, even while operating.

8. A light bulb including a plurality of Light Emitting Diodes (LEDs), comprising:
-
a driving circuit board; a longitudinal support structured to receive the driving circuit board; a board support structured to engage the longitudinal support; a generally dome-shaped printed circuit board having a plurality of LEDs mounted thereon and coupled to the board support, the dome-shaped printed circuit board including a number of individual LED panels structured to support individual ones of the LEDs, and the individual panels connected to one another through at least one circuit trace on the printed circuit board, the dome-shaped printed circuit board further including weakening grooves between the individual panels and partially through a thickness of the dome-shaped printed circuit; an electrical connection at a first end of the bulb; and a cover at a second end opposite the first end of the bulb, the cover structured to cover the dome-shaped printed circuit board. - View Dependent Claims (9, 10, 11, 12, 13)
