Abstract

An LED light apparatus and methodology that can produce a collinear beam of white or colored light. The apparatus has a housing which incorporates three sets of LED light assemblies each set having a plurality of LED lights arranged in an a x a, a x b or other suitable geometric pattern. Each set contains LED lights of the same color, being either red, blue or green. A dichroic bandpass filter and a dichroic notch filter are also incorporated. The apparatus is attached to a power driver which connects to a microcontroller, being a DMX controller, TC/IP controller, or the like. When the apparatus is turned on, red light from the red LED lights passes through the dichroic bandpass filter. The resulting light then combines with the blue light from the blue LED lights and passes through dichroic notch filter. This next light stream then combines with the green light from the green LED lights to form a collinear beam of white or colored light.

Claims

1. An LED light apparatus for producing a collinear beam of white or colored light comprising:

a housing;

at least three sets of LED light assemblies contained within said housing, wherein each of said sets of LED light assemblies is comprised of a plurality of LED lights, said LED lights being arranged in a geometric pattern, and wherein said LED lights contained within each of said sets of LED light assemblies are of the same color, said LED lights being of different colors between said sets of LED light assemblies;

a dichroic bandpass filter located between said sets of LED light assemblies;

a dichroic notch filter located between said sets of LED light assemblies intersecting said dichroic bandpass filter;

a power driver connected to each of said sets of LED light assemblies;

a microcontroller connected to said power driver;

wherein said at least three sets of LED light assemblies contain LED lights of blue, red, and green forming blue LED light assembly, red LED light assembly, and green LED light assembly.

2. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein the perimeter of said housing comprises a plurality of heat sinks to dissipate heat from said LED light apparatus.

3. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said housing incorporates a light emission screen for emitting the produced collinear beam of white or colored light.

4. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said blue LED light assembly is arranged at right angles to said red LED light assembly.

5. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said green LED light assembly is arranged at right angles to said red LED light assembly.

6. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said dichroic bandpass filter is at a 90 degree angle with said dichroic notch filter.

7. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said red LED light assembly is at a 45 degree angle with said dichroic bandpass filter.

8. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said blue LED light assembly is at a 45 degree angle with said dichroic bandpass filter.

9. The LED light apparatus for producing a collinear beam of white or colored light of claim 1 wherein said green LED light assembly is at a 45 degree angle with said dichroic notch filter.

10. A method of producing a collinear beam of white or colored light comprising the steps of:

emitting a third set of light rays from a third LED light assembly;

reflecting said third set of light rays against a second side of said dichroic notch filter; and

combining said third set of light rays with said combined light stream to form a collinear beam of white or colored light wherein said collinear beam of white or colored light passes through a light emission screen.

11. The method of producing a collinear beam of white or colored light of claim 10 wherein said second LED light assembly contains LED lights of blue forming a blue LED light assembly.

12. The method of producing a collinear beam of white or colored light of claim 11 wherein said blue LED light assembly is arranged at right angles to said red LED light assembly.

13. The method of producing a collinear beam of white or colored light of claim 10 wherein said third LED light assembly contains LED lights of green forming a green LED light assembly.

14. The method of producing a collinear beam of white or colored light of claim 13 wherein said green LED light assembly is arranged at right angles to said red LED light assembly.

15. The method of producing a collinear beam of white or colored light of claim 13 wherein said green LED light assembly is at a 45 degree angle with said dichroic notch filter.

16. A method of producing a collinear beam of white or colored light comprising the steps of:

emitting red light rays from a red LED light assembly;

striking said red light rays against a first side of a dichroic bandpass filter;

passing said red light rays through said dichroic bandpass filter;
