Disinfecting light fixture
First Claim
1. A light fixture comprising:
- at least one first light source that emits at a peak wavelength in a range of approximately 380 nanometers (nm) to approximately 420 nm;
at least one second light source that emits at a different peak wavelength, wherein a combined light output of the at least one first light source and the at least one second light source emits a colored light that is perceived as white light;
wherein the white light comprises a color rendering index (CRI) value of more than approximately 50;
wherein the at least one second light source that emits at a different peak wavelength consists of;
an xy coordinate on a International Commission on Illumination (CIE) 1931 xy color space diagram above a black body curve within a bounded area defined by a first line of approximately y=2.23989x−
0.382773 and a second line of approximately y=1.1551x−
0.195082; and
wherein the combined light output has a proportion of spectral energy measured in the approximately 380 nm to approximately 420 nm range of greater than approximately 20%.

Abstract
Disclosed herein is a light fixture. The light fixture includes at least one first light source that emits at a peak wavelength in a range of approximately 380 nm to approximately 420 nm and at least one second light source that emits at a different peak wavelength, wherein a combined light output of the at least one first light source and the at least one second light source emits a colored light that is perceived as white light. The white light is defined by having a color rendering index (CRI) value of more than approximately 50. The at least one second light source that emits at a different peak wavelength consists of an xy coordinate on a International Commission on Illumination (CIE) 1931 xy color space diagram above a black body curve within a bounded area defined by a first line of approximately y=2.23989x−0.382773 and a second line of approximately y=1.1551x−0.195082. The combined light output has a proportion of spectral energy measured in the approximately 380 nm to approximately 420 nm range of greater than approximately 20%.
