Light emitting diode replacement lamp
First Claim
1. An illumination device to replace a standard light bulb and to provide a decorative illumination characteristic, comprising:
- a standard light bulb power connector equivalent to a power connector of the replaced light bulb, the power connector being adapted to fit into a standard light bulb power socket and having input power contacts for receiving an input power from a power source;
at least one solid state light emitter;
driving circuitry electrically connected to the power connector and compact enough to fit into a volume envelope of the replaced light bulb, and comprising a solid state circuit which regulates the input power from the power source to provide a regulated power to the at least one solid state light emitter; and
a decorative illumination feature for producing a decorative illumination using light from at least one said solid state light emitter.

Abstract
The invention is a replacement for a conventional incandescent or halogen light bulb. Besides providing regular illumination, it has advantages over a conventional bulb while maintaining the bulb'"'"'s decorative function, such as visual effects associated with the bulb'"'"'s envelope or shade. The invention comprises a connector equivalent to a standard light bulb base, at least one light emitting diode (LED), and a driving circuit hosted on a module such as a printed circuit board and adapting the supply voltage to the requirements of the LED. Compensation for the effects of temperature may be included. The invention may also include other circuitry to support various enhanced features such as novel decorative features or control over the brightness, color, or other characteristics—all potentially varying over time or being controlled remotely.
