An LED light apparatus and methodology that can produce a collinear beam of light.
The apparatus has a housing with three sets of LED light assemblies each having
several LED lights of the same color, being red, blue or green. A dichroic bandpass
filter and a dichroic notch filter are incorporated along with a power supply.
In one embodiment both filters intersect forming an x-pattern. Red light passes
through both filters. The resulting light from the bandpass filter combines with
blue light and passes through the notch filter. This combined light stream then
combines with green light to form a collinear beam of white or colored light. The
resulting light from the red light passing through the notch filter combines with
green light and passes through the bandpass filter. This combined light stream
then combines with the blue light to form a collinear beam of white or colored light.
