A light engine that produces UVAlight, but not UVAor UVB radiation, that will provide a human or animal subject a beneficial application of artificial UVAlight without the deleterious effect of the UVAand UVB light. Methods of providing UVAlight to the human or animal subject over various periods of time provide positive treatments that can reduce stress, reduce anxiety, increase a pain threshold, and induce interferon production. Exposure to UVAwavelength light (360-400 nm) provides a positive effect on both humans and animals. This is especially true when the humans or animals do not receive UVB and UVAat the time that the UVAlight is received, and the ratio of UVAlight to (UVAlight+visible light) is greater than 10%.

Beneficial applications of UVA1 light

Sanitizing an agricultural facility by placing a chamber having an open interior within the agricultural facility. An item is placed within an open interior of the chamber and a door is interlocked. Then light having a spectral content within a narrow range of wavelengths is provided from at least one lighting device toward the item for a predetermined amount of time to inactivate a microorganism. Simultaneously, ozone may be discharged into the open interior to sanitize the item. Before the door unlocks the ozone within the interior of the chamber is directed to a filter for forming oxygen. Sanitizing the agricultural facility by detect humans, and in response, providing a first light with one spectral content when the human is detected, and providing a second light with a different spectral content within a narrow range of wavelengths to inhibit bacteria growth when humans are not detected.

Biosecurity system using monitoring and sanitization for an agricultural dwelling

A system and method to promote biological responses within incubated eggs using lighting devices within an incubation chamber. A light supporting device is installed within the incubation chamber in spaced relation to an incubation device housing a plurality of eggs. The light supporting device is positioned to direct light at pre-determined wavelengths into the interior cavity of the incubation device to irradiate the plurality of eggs to promote a biological response within the eggs.

Systems and methods for promoting biological responses in incubated eggs

The sex of embryos in eggs is influenced or controlled through the application of light having selected wavelengths in order to promote the development of embryos of a selected sex. An incubating device is provided having an interior cavity that can be sealed from an outside, and having a plurality of lighting elements in the interior cavity. Eggs are disposed in the interior cavity, and pre-determined environmental conditions are applied to the interior cavity to promote hatching of the eggs. Concurrently with the application of the environmental conditions, the eggs are irradiated according to pre-determined lighting conditions. The lighting conditions include applying light having wavelengths substantially concentrated in selected ranges, such as light wavelengths within the 440-460 nm, or other narrow range.

A method of stimulating plant growth in a controlled environment that includes providing a lighting assembly having a network of lighting elements such as light emitting diodes (LEDs) that provide light at a color tailored for an individual plant. The lighting assembly is positioned adjacent a plant such that the light produced is received by the plant. The lighting assembly additionally has a control assembly that includes driving circuitry that modulates the lighting elements to controllably provide predetermined periods of light and dark to stimulate continuous growth of the plant.

A control system for illuminating swine having one or more controllers configured to increase voltage supplied to a first plurality of lights to a first threshold voltage to illuminate the first plurality of lights to provide a first light having a first color characteristic that affects swine. The one or more controllers are also configured to increase the voltage supplied to a second plurality of lights to a second threshold voltage to illuminate the second plurality of lights to provide a second light with a second color characteristic different than the first color characteristic. The one or more controllers are also configured to increase the voltage supplied to a third plurality of lights to a third threshold voltage to illuminate the third plurality of lights to provide third light with a third color characteristic that stimulates the swine to have a predetermined behavior.

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.

A system and method for illuminating livestock within an agricultural dwelling. The system has a plurality of lighting assemblies that are electrically connected to a dimming device. The lighting assemblies are dimmed from a white color to predetermined wavelength to result in a predetermined behavior of the livestock. The predetermined wavelength and behavior includes a red wavelength that is undetected by the livestock thus resulting in the predetermined behavior of the livestock sleeping while workers can continue to work or function within the agricultural dwelling.
