A light engine that produces UVA1 light, but not UVA2 or UVB radiation, that will provide a human or animal subject a beneficial application of artificial UVA1 light without the deleterious effect of the UVA2 and UVB light. Methods of providing UVA1 light 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 UVA1 wavelength 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 UVA2 at the time that the UVA1 light is received, and the ratio of UVA1 light to (UVA1 light+visible light) is greater than 10%.

In some examples, the atmosphere inside the poultry facility may be around a substantially controlled temperature suitable for poultry. The atmosphere may further contain substantial Nitrogen-content suitable to promote algae growth. Various embodiments may symbiotically consume waste products from each facility to promote production of, for example, protein for food and algae, which may be used for animal feed, for example, and/or processed into fuel. In some examples, the algae production facility may be conveniently packaged into a module. In some examples, the module may be stored and shipped in a conventional shipping container.
A light source is provided with extended persistence and reduced flicker characteristics by using a light capacitive filter. In general, a light source can include an illumination source which converts electrical energy into emitted light. The illumination source, however, is generally powered by an AC waveform, and the periodic variations inherent in the AC waveform may cause flicker in the emitted light. To reduce the flicker, a light capacitive filter is included in the light source to filter the light emitted by the illumination source and produce a light output with reduced flicker. In some examples, the light capacitive filter includes a medium persistence phosphor having a decay constant (or half-life) of between 1 milliseconds and 2 seconds.

Spectral shift control for dimmable AC LED lighting
Apparatus and associated methods involve operation of an LED light engine in which a relative intensities of selected wavelengths shift as a function of electrical excitation. In an illustrative example, current may be selectively and automatically diverted substantially away from at least one of a number of LEDs arranged in a series circuit until the current or its associated periodic excitation voltage reaches a predetermined threshold level. The diversion current may be smoothly reduced in transition as the excitation current or voltage rises substantially above the predetermined threshold level. A color temperature of the light output may be substantially changed as a predetermined function of the excitation voltage. For example, some embodiments may substantially increase or decrease a color temperature output by a solid state light engine in response to dimming the AC voltage excitation (e.g., by phase-cutting or amplitude modulation).
Apparatus and associated methods involve an assembly of multiple LED light engines in which a desired number of LED lamps are mounted to a plate that forms a wall of an enclosure. In an illustrative example, three LED light engines may be mounted to a plate that may be slidably installed as a wall of an extruded housing that contains electrical connections from an AC power inlet to each light engine. In various examples, the number and layout arrangement of the LED light engines may be custom selected for a particular application.
Exemplary apparatus and associated methods involve a bypass module for modulating conductivity of one or more current paths to provide a first set of LEDs that are conducting near minimum output illumination and having a larger conduction angle than that of a second set of LEDs that conduct at a maximum output illumination. In an illustrative example, the conductivity of a bypass path in parallel with a portion of the second set of LEDs may be reduced while the AC input excitation is above a predetermined threshold voltage or current. The bypass path may be operated to provide a reduced effective turn-on voltage while the input excitation is below the predetermined threshold. For a given maximum output illumination at a maximum input excitation, the bypass module may control current through selected LEDs to construct an input current waveform with substantially improved power factor and reduced harmonic distortion.
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.

Methods and apparatus for high power factor power transfer to a load using a single switching stage. In exemplary implementations, a controllable variable power may be delivered to a load using a single switching stage while maintaining high power factor, in some cases without requiring any feedback information relating to the load conditions (i.e., without monitoring load voltage and/or current) to control normal switching operations in the single switching stage, and without requiring regulation of load voltage and/or load current. In one example, a single stage high power factor driver is used to control power delivery to an LED-based light source.
Methods for allocating power amongst different source spectrums, or "channels," of a multi-channel lighting unit, and apparatus that employ such methods. Power allocation methods exploit the total light-generating capability of a lighting unit while maintaining safe operating power conditions, so as to avoid damage to the lighting unit due to excessive thermal power generation. In one example, a power allocation method ensures that a lighting unit operates at or near its maximum power handling capability for a variety of possible high brightness lighting conditions by ascribing a maximum per channel operating power equal to the maximum power handling capability of the lighting unit. The power allocation method then reapportions, if necessary, prescribed operating powers for multiple channels, in response to a given lighting command, such that the ratio of the prescribed powers remains the same but the sum of the channel operating powers does not exceed the maximum power handling capability of the lighting unit.
