Abstract

A LED lighting assembly comprising at least one LED; the at least one LED being mounted to a support; at least one solar element for creating electric power from solar power; at least one battery for storing electricity generated by the solar element; at least one wind vane operatively associated with the support; at least one motor/generator having a first mode for generating electric power from the wind turbine; and at least one shaft operatively connected to the at least one motor/generator and the support; the motor/generator having a second mode in which the motor/generator operates to rotate the support; the at least one motor/generator being operatively connected to the at least one battery for storing electric power therein.

Claims

1. An LED lighting assembly comprising:

at least one LED;

the at least one LED being mounted to a support;

at least one solar element for creating electric power from solar power;

at least one battery for storing electricity generated by the solar element;

at least one wind vane operatively associated with the support;

at least one motor/generator having a first mode for generating electric power from the at least one wind vane; and

at least one shaft operatively connected to the at least one motor/generator and the support;

the motor/generator having a second mode in which the motor/generator operates to rotate the support;

the at least one motor/generator being operatively connected to the at least one battery for storing electric power therein.

2. The assembly of claim 1 further comprising a light detector;

the light detector controlling the operation of the LED.

3. The assembly of claim 1 further comprising a light detector that operates to turn the LED on and off.

4. The assembly of claim 1 wherein the support is operatively associated with a shaft for rotation thereon;

and wherein the support has a plurality of wind vanes operatively associated therewith which cause the support to rotate and causes the shaft to rotate which causes the at least one motor/generator to generate electric power in the first mode; and

when the motor/generator is in the second mode, the motor/generator causes the support to rotate whereby the wind vanes operate to cool the at least one LED.

5. The assembly of claim 1 wherein the at least one wind vane comprises a plurality of wind vanes operatively associated with the support to form a wind turbine;

the support being operatively associated with the shaft;

the shaft being operatively associated with the at least one motor/generator, such that when the motor/generator is in the first mode, the wind causes the wind turbine to turn and the motor/generator operates to generate electricity, and when the motor/generator is in the second mode, the motor/generator causes rotation of the support to generate air flow to cool the at least one LED.

6. The assembly of claim 1 wherein at least one motor/generator comprises a motor which rotates the support.

7. The assembly of claim 1 further comprising at least one strobe element which causes the LED to turn on and off.

8. The assembly of claim 7 wherein the strobe element is operatively associated with the shaft;

whereby as the shaft rotates the strobe element makes contact intermittently causing intermittent operation of the at least one LED.

9. The assembly of claim 1 wherein the at least one solar element comprises a surface for absorbing sunlight, the at least one solar element and the support are supported by the shaft;

the shaft being pivotally mounted to a pivot which is driven by a second motor,

whereby through the operation of the motor the solar element surface is positioned to absorb sunlight from the sun as the sun rises and sets.

10. The assembly of claim 1 further comprising a cover operatively associated with the support and a wind direction detector operatively associated with the cover causing the cover to turn when the wind changes direction;

and wherein the at least one vane comprises a plurality of wind vanes operatively associated with the support to cause rotation thereof; and

wherein the wind causes the support to rotate, the cover covers the wind vanes for which the force of the wind is in a direction opposite to the rotation of the vanes.

11. The assembly of claim 9 further comprising a controller which is programmable which controls the operation of the first and second motors.

12. The assembly of claim 1 wherein the at least one LED and the at least one solar element are fabricated as a single unit.

13. The assembly of claim 1 wherein the at least one LED comprises a first semiconductor crystal and the at least one solar element comprises a second semiconductor crystal, the first and second semiconductor crystals being formed on a common substrate.

14. The assembly of claim 1 further comprising a programmable controller for controlling the motor/generator for selectively changing the motor/generator from the first to the second mode.

15. The assembly of claim 1 further comprising a temperature sensor and wherein the motor/generator operates in the first mode when the wind is causing the support to turn and operates in the second mode in response to the temperature sensor to generate air flow to cool the assembly.

16. The assembly of claim 1 further comprising an ambient light condition detector and wherein the at least one LED is activated by the ambient light condition detector.
