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 between 380 nm and 780 nm and having at least one local maximum in relative intensity at a wavelength within 15 nm of 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; and
wherein at least one local maximum in relative intensity of the second spectral content is above the median relative intensity of local maxima of the second spectral content.

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.
