Abstract

An LED with two or more leads with built-in and/or built-on circuitry that changes colors and patterns automatically. The LED preferably has a size, including the circuitry, of not more than about 10 mm in any direction. Preferably, the circuitry is built in. These LEDS typically can be used in place of normal LEDS without modification of the product in which the LEDS are used.

Claims

1. An LED with two or more leads with built-in and/or built-on circuitry that changes colors and patterns automatically.

6. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 10 mm in any direction.

7. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 8 mm in any direction.

8. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 5 mm in any direction.

9. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 4.8 mm in any direction.

10. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 4.7, mm in any direction.

11. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 4.6 mm in any direction.

12. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 4, mm in any direction.

13. The LED of claim 1, wherein the LED has a size, including the circuitry, of not more than about 3 mm in any direction.

14. The LED of claim 1, wherein the circuitry is built in.

15. A Color Changing LED Keychain with the LED of claim 1 and a battery or batteries.

16. A Color Changing LED mini wedge bulb with one or more LEDS of one of claim 1 and external circuitry (resistor(s), diode(s), zener(s))(for voltage and current regulation only), connectors, housing, and base.

17. Apparatus including the LED of claim 1.

2. Color changing LED bulbs with voltage and/or current regulation.

4. The color changing LED bulbs of claim 2, comprising AC bulbs.

19. The color changing LED bulbs of claim 2, comprising DC bulbs.

3. Color changing LED bulbs without voltage or current regulation.

5. The color changing LED bulbs of claim 3, comprising AC bulbs.

20. The color changing LED bulbs of claim 3, comprising DC bulbs.
