Abstract:
A light emitting diode (LED) with a melanopic emission spectrum can comprise a primary light source and a phosphor. The primary light source can comprise an emission spectrum comprising a first peak centered at a wavelength from 480 nm to 500 nm. The phosphor, when excited, can comprise an emission spectrum with a second peak centered at a wavelength from 640 nm to 750 nm, and the intensity of the first peak is greater than the intensity of the second peak. A light emitting apparatus can comprise a first LED with a traditional white light emission spectrum, and a second LED with a melanopic emission spectrum. The light emitted from the apparatus can comprise chromaticity coordinates, in the CIE 1931 color space diagram using the 196410° Supplementary Standard Observer, that are within a one-step MacAdam ellipse from the black body locus with chromaticity coordinate x from 0.34 to 0.45.
