Abstract: Disclosed is a method and apparatus for providing a solid state light emitter and driving circuitry integrated into a component module that will retrofit common incandescent light bulb applications. The disclosed embodiment is directed to the retrofitting of small flashlights using miniature bulbs, such as the Mini Maglite®. Because the emitter and driving circuitry cannot readily fit within the envelope of the bulb being replaced, the volume occupied by the module needs to be acquired from within the flashlight's interior, such as from part of the volume occupied by the reflector. In that case, the invention includes a replacement reflector supplied with the module. The invention provides that no original functionality of the flashlight is sacrificed. Consideration is also given to the conduction of heat from the light emitter and module.

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.
