Abstract

A light system for a fireplace, including a plurality of lights, and a chaos circuit coupled to the plurality of lights. The chaos circuit is configured to provide signals to the plurality of lights to provide naturalistic flame lighting and naturalistic ember lighting.

First claim

What is claimed is:

1. A light system for a fireplace, comprising:
a plurality of lights; and
a chaos circuit coupled to the plurality of lights and configured to provide signals to the plurality of lights to provide naturalistic flame lighting and naturalistic ember lighting,
wherein the plurality of lights includes at least two backlights that receive at least one of the signals and the at least two backlights flicker based on the at least one of the signals to provide the naturalistic flame lighting, wherein the at least two backlights are synchronized to provide the naturalistic flame lighting.

2. The light system of claim 1 , wherein the at least two backlights are situated to reflect off one or more walls of the fireplace.

3. The light system of claim 1 , wherein the plurality of lights includes at least one ember light that receives one or more of the signals and the at least one ember light irregularly glows based on the one or more of the signals to provide the naturalistic ember lighting.

4. The light system of claim 3 , wherein the at least one ember light is situated behind artificial embers in the fireplace to illuminate the artificial embers.

5. The light system of claim 1 , wherein the plurality of lights includes at least three ember lights that receive one or more of the signals and the at least three ember lights irregularly glow based on the one or more of the signals to provide the naturalistic ember lighting.

6. The light system of claim 1 , wherein the chaos circuit includes:
at least one microprocessor that generates random numbers;
at least one filter that provides filtered results based on the random numbers; and
analog circuitry that receives the filtered results and provides the signals to drive the plurality of lights.

7. The light system of claim 3 , wherein the analog circuitry includes:
an oscillator that generates an oscillator output signal; and
at least one comparator that receives the oscillator output signal and the filtered results to provide the signals.

8. The light system of claim 1 , wherein the chaos circuit includes a plurality of microprocessors that generate random numbers based on the rate of power applied to each of the plurality of microprocessors.

9. The light system of claim 1 , wherein the chaos circuit includes a plurality of microprocessors and a difference in the rate of power applied to each of the microprocessors influences random number generation by another one of the plurality of microprocessors.

10. The light system of claim 1 , wherein the chaos circuit includes:
a plurality of microprocessors configured to generate random numbers;
an oscillator configured to provide an oscillator output signal; and
a plurality of analog comparators configured to receive the oscillator output signal and to receive filtered results based on the random numbers, wherein each of the plurality of microprocessors is coupled to a corresponding one of the plurality of analog comparators.

11. The light system of claim 1 , wherein the chaos circuit automatically generates the signals in response to power being applied to the chaos circuit.

12. A light system for a fireplace, comprising:
lights; and
a chaos circuit coupled to the lights, the chaos circuit configured to provide drive signals that illuminate the lights to provide naturalistic lighting, the chaos circuit comprising:
a plurality of microprocessors configured to generate random numbers; and
an analog circuit that receives filtered signals based on the random numbers and provides the drive signals based on the filtered signals.

13. The light system of claim 12 , wherein the chaos circuit comprises:
an oscillator configured to provide an oscillator output signal; and
a plurality of analog comparators configured to receive the oscillator output signal and to receive the filtered results.

14. The light system of claim 13 , wherein each of the plurality of microprocessors is coupled to a corresponding one of the plurality of analog comparators.

15. The light system of claim 12 , wherein the lights include at least one backlight and the analog circuit provides at least one backlight signal to illuminate the at least one backlight to provide naturalistic flame lighting.

16. The light system of claim 12 , wherein the lights include at least one ember light and the analog circuit provides at least one ember light signal to illuminate the at least one ember light to provide naturalistic ember lighting.

17. The light system of claim 12 , wherein each of the plurality of microprocessors includes a program that generates polynomial results, uses the polynomial results to generate the random numbers, and directs the microprocessor to output least significant bits of the random numbers to produce a pulse width modulated output signal that is filtered and provided to the analog circuit to generate the drive signals.

18. The light system of claim 12 , wherein the chaos circuit automatically generates the drive signals in response to power being applied to the chaos circuit.

19. A method of providing light in a fireplace, the method comprising:
generating signals using a chaos circuit; and
providing the signals to a plurality of lights to provide naturalistic lighting,
wherein generating signals and providing the signals comprises:
generating random numbers via a plurality of microprocessors;
providing filtered results based on the random numbers;
generating an oscillator output signal via an oscillator; and
comparing the oscillator output signal and the filtered results at a plurality of analog comparators, wherein each of the plurality of analog comparators receives a corresponding one of the filtered results that is based on the random numbers from one of the plurality of microprocessors.

20. The method of claim 19 , wherein generating signals and providing the signals comprises:
generating at least one backlight signal using the chaos circuit; and
providing the at least one backlight signal to at least one backlight, such that the at least one backlight flickers in response to the at least one backlight signal to provide naturalistic flame lighting.

21. The method of claim 19 , wherein generating signals and providing the signals comprises:
generating at least one backlight signal using the chaos circuit; and
providing the at least one backlight signal to at least two backlights, such that the at least two backlights flicker in response to the at least one backlight signal and the at least two backlights are synchronized to provide naturalistic flame lighting.

22. The method of claim 19 , wherein generating signals and providing the signals comprises:
generating at least one ember light signal using the chaos circuit; and
providing the at least one ember light signal to at least one ember light, such that the at least one ember light irregularly glows in response to the at least one ember light signal to provide naturalistic ember lighting.

23. The method of claim 19 , wherein generating signals and providing the signals comprises:
generating at least one ember light signal using the chaos circuit; and
providing the at least one ember light signal to at least three ember lights, such that the at least three ember lights irregularly glow in response to the at least one ember light signal to provide naturalistic ember lighting.
