Light sources adapted to spectral sensitivity of diurnal avians and humans
First Claim
1. A method of illuminating diurnal avians with artificial light sources, the method comprising:
- supplying a first light having a first spectral content between 380 nm (nanometers) and 780 nm to a substantially enclosed habitat for diurnal avians;
supplying a second light having a second spectral content and having at least one local maximum in relative intensity at a wavelength at which a predetermined characteristic visual spectral response of the diurnal avian has a local maximum to a substantially enclosed habitat for diurnal avians, wherein the second spectral content has at least one local maximum in relative intensity that is within 30 nm of the wavelength at which a predetermined characteristic visual spectral response of the diurnal avian has a local maximum and the second spectral content does not have content between 620 nm and 630 nm.

Abstract
Various apparatus and associated methods involve a light source that provides light at wavelengths that substantially correlate to local maxima in the spectral sensitivity of a diurnal avian. In an illustrative example, the light source may output light primarily in wavelength bands that are not substantially absorbed by colored oil droplets and/or visual pigment in at least one type of cone in the eye of a diurnal avian. In some embodiments, the light source may include a light-emitting diode (LED) light source. Exemplary light sources may output spectral components to illuminate diurnal avians with local maxima of intensity at wavelengths that substantially correspond to local maxima in a spectral sensitivity visual response characteristic of the diurnal avians.
