Universal light emitting diode illumination device and method
First Claim
1. An assembly for an illumination device that incorporates a light fixture, the assembly comprising:
- a printed circuit board having (i) top and bottom opposed, substantially rectangular surfaces, and (ii) first and second shorter-length sides (a) having lengths less than lengths of the remaining two sides and (b) spanning the top and bottom surfaces;
first and second electrically conductive bumps on opposing ends for (a) use as electrical input and output and (b) direct physical mounting in and direct electrical connection with the light fixture without wires attached to the first and second electrically conductive bumps, wherein (i) the first electrically conductive bump is disposed on the first shorter-length side, (ii) the second electrically conductive bump is disposed on the second shorter-length side, and (iii) the first and second electrically conductive bumps protrude from the first and second shorter-length sides (a) in opposite directions, and (b) in directions substantially parallel to surface normals of the first and second shorter-length sides;
at least one solid-state light emitter electrically connected to the printed circuit board; and
disposed on the printed circuit board, a driving circuit in electrical communication with the electrically conductive bumps and the at least one solid-state light emitter for providing suitable current to the at least one solid-state light emitter.

Abstract
Disclosed is a method and apparatus for providing a light emitting diode and driving circuitry integrated into a component module that will retrofit common incandescent lightbulb applications. The disclosed embodiments will perform with high efficiency at a wide operating voltage range with a very small size allowing for the incorporation within the envelope and form of existing lightbulb bases. Therefore, a single universal LED light bulb module can be used to replace the dozens of conventional LED and incandescent lights currently being used. The electronic circuitries used to drive the LEDs are extremely compact and consequently can be incorporated in nearly any standard bulb base.
