Abstract
Described herein is a system and method to convert the photons of a first color of light emitted by a light source to photons of second color of light that is more easily distinguished from other colors by people with color blindness.
Claims19
A system, comprising:
- an appliance;
- a light output source positioned on the appliance that outputs a first color of light that is hard for people with color blindness to distinguish from other colors;
- and
- a photon converting material overlying the light output source of the appliance, the photon converting material being operative to convert the first color of the light emitted by the light output source from the first color to a second, different color of different wavelength that is more distinguishable for people with color blindness than the first color.
1 more element
A light color converting system, comprising:
- a substrate;
- a photon receiving material positioned in the substrate, the photon receiving material configured to be positioned to receive a photon of light of a first color;
- a photon color converting assembly adjacent to the photon receiving material, the photon color converting material being operative to convert the color of the received photon of light from the first color to a second, different color of a different wavelength.
