Abstract
A light fixture including a substrate and a plurality of light emitting diodes mounted on the substrate. The plurality of light emitting diodes includes a first light emitting diode having a peak wavelength within a range of 600 nanometers and 630 nanometers, and a full width at half maximum value of at least 140 nanometers.
Claims17
A light emitting diode comprising:
- a peak wavelength within a range of 600 nanometers and 630 nanometers;
- a full width at half maximum value within a range of 140 nanometersto 160 nanometers;
- and
- a spectral power distribution that is asymmetrical and skewed about a center wavelength toward longer wavelengths;
- wherein the light emitting didoe (34) has a spectral power distribution that reflects a skew normal distribution with a skew parameter within a range of 0.0 and −1.5.
