This application is a continuation of U.S. patent application Ser. No. 12/843,218 filed 26 Jul. 2010 entitled “Thermally switched optical downconverting filter,” which is a divisional of U.S. patent application Ser. No. 12/019,602 filed 24 Jan. 2008 entitled “Thermally switched optical downconverting filter,” which claimed the benefit of priority pursuant to 35 U.S.C. §119(e) of U.S. provisional patent application No. 60/897,184 filed 24 Jan. 2007 and U.S. provisional patent application No. 60/931,068 filed 21 May 2007, each of which is hereby incorporated herein by reference in its entirety.
1. A reflective film for regulating reflection of incident radiant energy comprising
a first optical filter layer;
a second optical filter layer; and
a temperature-responsive optical material positioned between the first optical filter layer and the second optical filter layer.
3. The film of claim 1, wherein
the temperature-responsive optical material adjusts an optical property of incident light when below a threshold temperature;
the first optical filter layer reflects up to 50% of the incident radiant energy and transmits a majority of non-reflected radiant energy; and
the second optical filter layer reflects up to 100% of radiant energy transmitted by the first optical filter layer when the temperature-responsive optical material is above the threshold temperature and transmits up to 100% of radiant energy transmitted by the first optical filter layer when the temperature-responsive material is below the threshold temperature.
5. The device of claim 1, wherein the second optical filter layer is frequency selective with respect to an optical property of the radiant energy.
6. The film of claim 1, wherein the film is in the form of a thin and flexible film.
7. The film of claim 1 further comprising a transparent substrate that supports the first optical filter layer, the second optical filter layer, and the temperature-responsive optical material.
8. The film of claim 7, wherein the transparent substrate is a rigid film.
9. The film of claim 1 further comprising a transparent substrate.
10. The film of claim 1, wherein the film is incorporated into a construction material for regulating the flow of incident light into, and thus regulating the internal temperature of, a building, a vehicle, or other structure.
11. The film of claim 10, wherein the construction material is an insulating glass unit.
12. The film of claim 1, wherein a range of wavelengths of radiant energy regulated by the film comprises one or more of visual, infrared, or near-infrared wavelengths.
13. The film of claim 1, wherein either or both of the first optical filter layer and the second optical filter layer is spectrally selective.
14. The film of claim 1, wherein the first optical filter layer and the second optical filter layer each have different filtering efficiencies, filtering responses, or both at different frequencies.
15. The film of claim 1, wherein each of the first optical filter layer and the second optical filter layer has a different filtering nature at different frequencies.
16. The film of claim 1, wherein either or both of the first optical filter layer and the second optical filter layer comprises a combination of multiple optical filter layers.
17. The film of claim 1, wherein the temperature responsive optical material comprises a liquid crystal.
18. The film of claim 17, wherein the liquid crystal further comprises an additive in a mixture with the liquid crystal to affect optical properties of the liquid crystal, a speed of transition between physical states of the liquid crystal, or both.
19. The film of claim 18, wherein the additive comprises a second type of liquid crystal mixed with the liquid crystal.
20. The film of claim 17, where the additive is selected to improve the stability of a functional response of the film to environmental conditions.
21. The film of claim 1, where the temperature-responsive optical material is designed or selected based upon frequency dependent properties of the temperature-responsive optical material with respect to an filtered property of light to affect one or more of aesthetic, color, light or energy transmission, absorption, and reflection properties of the film.
22. A reflective film for regulating the reflection of light comprising
a first optical filter layer that reflects up to 50% of incident light and passes up to 50% of the incident light;
a second optical filter layer, and
a temperature-responsive optical material positioned between the first optical filter layer and the second optical filter layer that adjusts an optical property of incident light below a threshold temperature, wherein
above the threshold temperature up to 100% of incident light is reflected by the film, and
below the threshold temperature up to 50% of incident light is reflected by the film.
23. The film of claim 1, wherein the temperature responsive optical material is a thermotropic distributed Bragg reflector.
24. The film of claim 1, either or both of the first and second optical filter layers comprise a distributed Bragg reflector.
25. The film of claim 1, wherein the first optical filter layer, the temperature-responsive optical material, and the second optical filter layer collectively form a distributed Bragg reflector.
