Abstract
Abstract The method and apparatus for producing ornamental lighting displays utilizing electronic circuitry in the nature of a commutator which responds to binary signals produced from a plurality of orderly and/or random sources of energy and functions to illuminate one or more light sources depending on the binary combinations produced by the energy sources. The light sources may be light emitting diodes or other light sources depending on the power available and may be arranged in a variety of ornamental patterns.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
148 words
Apparatus for producing an ornamental light display comprising a plurality of light sources arranged to form an ornamental pattern, a plurality of generating means for producing a plurality of sets of binary input signals of different periodicities, means for sensing the successive changes in the orders of binary bits produced by said signals and producing a set of binary output signals and means for feeding said output signals to said light sources for illuminating selected light sources with each specific order of bits being sensed, second sensing means, means for feeding a plurality of binary input signals to said second sensing means whereby the last said sensing means produces a second set of binary output signals and each of said light sources is connected between selected output terminals of the first said and second sensing means and illuminated each time a voltage difference occurs across each light source.

Claim 3
Dependent Claim
17 words
Apparatus for producing an ornamental light display according to claim 1 wherein said light sources are LEDs.
Claim 4
Dependent Claim
40 words
Apparatus for producing an ornamental light display according to claim 1 wherein said generating means comprises a plurality of square wave oscillators for producing said sets of binary input signals and means for individually adjusting the frequency of each oscillator.
Claim 5
Dependent Claim
53 words

Dependent Claim
21 words
Apparatus for producing an ornamental light display according to claim 1 wherein said light sources are arranged in a rectangular array.
Claim 7
Dependent Claim
21 words
Apparatus for producing an ornamental light display according to claim 1 wherein said light sources are arranged in a spiral array.
