Light Sources Adapted to Spectral Sensitivity of Diurnal Avians and Humans

摘要

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.

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.
