Abstract
In one aspect, a luminaire is provided for illumination, in which the luminaire has a normalized spectral power distribution (SPD) curve for promoting human wellness, the normalized SPD curve having the following percentage areas for the following wavelength domains, the normalized SPD curve including spectral energy in a 620 nm to 640 nm region of the SPD curve ranging from 9.5% to 10.5% of a total of an area for a normalized SPD curve; spectral energy in a 640 nm to 660 nm region of the SPD curve ranging from 7.25% to 9.8% of the total of the area of the normalized SPD curve; spectral energy in a 660 nm to 680 nm region of the SPD curve ranging from 4.8% to 7.8% of the total of the area for the normalized SPD curve; spectral energy in a 680 nm to 700 nm region of the SPD curve ranging from 2.75% to 5.5% of the total of the area for the normalized SPD curve; and a remainder of spectral energy of the total normalized SPD curve is in a 400 nm to 620 nm region area of the SPD curve.
