Abstract
The present disclosure relates to products and methods for modifying the reflection of a light source in a fireplace and other products.
Claims14
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.

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.
