Light emitting diode replacement lamp
View Patent ↗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.
1. A method of providing illumination capable of replacing the illumination from incandescent light bulbs, including halogen light bulbs, comprising steps of
providing a standard light bulb power connector the same as that as for a conventional incandescent light bulb which the device replaces, the power connector adapted to fit into at least one of many standard light bulb power sockets, the power connector having input power contacts for receiving an input voltage from a power source;
electrically connecting a circuit module to the input power contacts of the power connector;
electrically connecting at least one LED to an output of the module;
physically connecting each LED to the module;
physically connecting the module to the power connector;
fitting the module and all LEDs into the volume envelope of the incandescent light bulb;
converting the input voltage to a voltage required by the LEDs;
providing light from the LEDs to produce decorative illumination in addition to general, non-decorative illumination.
2. The method of claim 1 , further comprising a step of directing at least some of the illumination onto a shade.
3. The method of claim 1 , further comprising a step of responding to commands from a wireless remote control device in order to control characteristics of the illumination.
4. The method of claim 1 , further comprising a step of providing manual control of characteristics of the illumination.
5. The method of claim 4 , in which a switch provides the manual control.
6. The method of claim 1 , further comprising a step of responding to commands from a wireless remote control device.
7. The method of claim 1 , further comprising a step of detecting a level of environmental, ambient illumination.
8. The method of claim 1 , further comprising a step of changing at least one of the decorative and non-decorative illumination in response to a proximity sensor.
9. The method of claim 1 , further comprising a step of communicating with other illumination devices.
10. The method of claim 1 , further comprising a step of continuing operation if source voltage fails.
11. The method of claim 10 , in which a back-up battery provides for the continuing operation.
12. The method of claim 1 , further comprising a step of preventing excessive current flow through the LEDs.
13. The method of claim 1 , further comprising a step of preventing heating of components beyond specified temperatures.
14. The method of claim 1 , further comprising a step of utilizing a D.C. (direct current) source voltage.
15. The method of claim 1 , further comprising a step of utilizing an A.C. (alternating current) source voltage.
16. The method of claim 1 , further comprising a step of positioning at least one lens with respect to at least one LED to focus and direct its illumination to change the illumination characteristics.
17. The method of claim 16 , wherein the positioning is accomplished by moving the lens electro-mechanically.
