LED lighting for livestock development
Apparatus and associated methods involve a hangable LED light assembly constructed to provide a selected color output illumination as a function of excitation intensity. In an illustrative example, the color output may be selected to promote biological development throughout livestock development stages (e.g., incubation, growth, and reproduction). The light intensity may controllable, for example, in response to a light dimmer arranged to modulate AC excitation applied to the LED downlight. As the light intensity is decreased in response to a simple dimmer control, the spectral output of the LED downlight may shift its output wavelengths. Accordingly, some exemplary installations may provide controlled combinations of intensity and color to substantially optimize lighting conditions for livestock.
1. A method of artificially illuminating swine during a life cycle to promote growth of the swine, the method comprising:
providing an electric lamp configured to illuminate a livestock area in which swine develop;
illuminating the livestock area with illuminants within the lamp, wherein the illuminants generate a selected wavelength;
illuminating the livestock area with other illuminants within the lamp; and
illuminating swine with the selected wavelength during selected portions of the swine lifecycle; and
simulating a sunrise by increasing light intensity on the swine with a program on a selected program schedule to promote growth of the swine.
2. The method of claim 1 , wherein the selected wavelength comprises a red color.
3. The method of claim 1 , wherein the selected wavelength comprises an infrared color.
4. The method of claim 1 , wherein the selected wavelength comprises a blue color.
5. The method of claim 1 , further comprising the step of reducing a peak intensity level of illumination once the swine in the livestock area have reached a predetermined maturity level.
6. The method of claim 1 , further comprising selectively discontinuing illuminating the swine with the selected wavelength and illuminating the livestock area with the other illuminants that output a white color.
