  • Patent number: 10485072
    Abstract: A light emitting diode lighting assembly that receives an electrical excitation signal that is varied from a dimming device. Driving circuitry receives the varying input and has first and second paths that each have a plurality of light emitting diodes. Each plurality of light emitting diodes has a threshold voltage with the threshold voltage of the first plurality of diodes being less than the threshold voltage of the second plurality of lighting emitting diodes. The current within the first path is controlled by a current limiting device that is controlled by a resistor that receives input from the second path to gradually turn off the first plurality of light emitting diodes as the second plurality of lighting emitting diodes increase in intensity. A shunt voltage regulator within the circuit having a threshold voltage that is above threshold voltages of components in the assembly to minimize voltage increases in the assembly.

  • Patent number: 9775212
    Abstract: 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).

  • Publication number: 20150343103
    Abstract: A UV chamber for inactivating microorganisms in an agricultural facility and method of enhancing sanitation in an agricultural facility using the same. Items are placed inside the UV chamber when entering an agricultural facility. The chamber locks enclosing the item therein and a lighting device directs UV radiation toward the item for a predetermined amount of time necessary to inactivate any microorganisms on the items. The inactive microorganisms are then exposed to the animals within the facility so the animals can build immunity to the microorganism.
