Geometric panel lighting apparatus and methods

A geometric panel apparatus, comprising:

• a plurality of LEDs adapted to output at least first radiation having a first spectrum and second radiation having a second spectrum different than the first spectrum;
• at least one geometric panel disposed with respect to the plurality of LEDs so as to at least partially diffuse the first radiation and the second radiation to provide a mixed spectrum when both the first radiation and the second radiation are generated;
• and
• at least one controller coupled to the plurality of LEDs and configured to independently control at least a first intensity of the first radiation and a second intensity of the second radiation at a plurality of graduated intensities from a minimum intensity to a maximum intensity.

A method of generating at least one variable color visible effect over at least a two-dimensional observation area, comprising acts of:

• A) generating from a plurality of LEDs at least first radiation having a first spectrum and second radiation having a second spectrum different than the first spectrum;
• B) at least partially diffusing the first radiation and the second radiation to provide a mixed spectrum, when both the first radiation and the second radiation are generated, via at least one geometric panel disposed with respect to the plurality of LEDs so as to receive the first radiation and the second radiation;
• and
• C) independently controlling at least a first intensity of the first radiation and a second intensity of the second radiation at a plurality of graduated intensities from a minimum intensity to a maximum intensity.
