Abstract

The present disclosure relates to products and methods for modifying the reflection of a light source in a fireplace and other products.

First claim

The invention claimed is:

1. A product comprising:
an enclosure having one or more of a top side, a bottom side, a front side, a back side, a left side and a right side of the enclosure; and
a source of light that produces a first light in the enclosure;
wherein one or more of the top side, bottom side, back side, left side and right side is entirely or less than entirely a non-metallic side and comprises a coating composition,
wherein the first light is reflected by the non-metallic side to produce a second light with a reflected emission spectrum; and
wherein between a spectrum of a normalized natural gas flame and the reflected emission spectrum there is a color shift Δxy that is greater than 0.007.

2. The product of claim 1 , wherein the color shift Δxy is greater than 0.030.

3. The product of claim 1 , wherein the color shift Δxy is greater than 0.070.

4. The product of claim 1 , wherein the non-metallic side comprises at least one material selected from the group consisting of: glass-ceramic, glass, ceramic, tempered soda lime glass, quartz-glass, borosilicate glass, aluminosilicate glass, and any combination thereof.

5. The product of claim 1 , wherein the coating composition comprises at least one material selected from the group consisting of: a metal oxide, a nitride, an oxynitride, a silicon-based composition, and any combination thereof.

6. The product of claim 1 , wherein the coating comprises at least one material selected from the group consisting of: titanium dioxide, titanium nitride, titanium oxynitride, aluminum silicon nitride, aluminum silicon oxide, silicon oxynitride, tin oxide, indium tin oxide, silicon dioxide, tin nitride, zinc oxide, aluminum oxide, aluminum oxynitride, silicon nitride, a thermocatalytic coating composition, and any combination thereof.

7. The product of claim 1 , wherein the coating composition comprises aluminum silicon oxide.

8. The product of claim 1 , wherein the coating composition comprises tin oxide.

9. The product of claim 1 , wherein the non-metallic side is colored, transparent and coated with a coating composition comprising aluminum silicon oxide.

10. The product of claim 1 , wherein the non-metallic side is uncolored, transparent and coated with a coating composition comprising aluminum silicon oxide.

11. The product of claim 1 , wherein the front side of the enclosure does not have the coating composition.

12. The product of claim 1 , wherein the back side is non-metallic and comprises the coating composition.

13. The product of claim 1 , wherein the top side, bottom side, front side, back side, left side and right side of the enclosure each comprise a surface facing an interior of the enclosure, and wherein one of the surfaces comprises the coating composition.

14. A product comprising:
an enclosure having a substrate defining one or more of a top side, a bottom side, a front side, a back side, a left side and a right side of the enclosure; and
a source of visible light disposed in the enclosure and that produces a first visible light;
wherein the substrate is entirely or less than entirely non-metallic and comprises a coating composition on an interior facing surface of the enclosure,
wherein the first visible light is reflected by the coating composition to produce a second light with a reflected emission spectrum; and
wherein the reflected emission spectrum and a spectrum of a normalized natural gas flame has a color shift Oxy therebetween that is greater than 0.007.
