  • Patent number: 10288240
    Abstract: A system and method of converting a light fixture from a conventional light fixture to an LED light fixture. Originally, the light fixture has a troffer, a ballast unit, and bulb receptacles. The conversion is accomplished by mounting a panel over the face of the troffer that obscures the ballast unit and bulb receptacles. LED light strips are mounted to the panel. Likewise, an LED power supply is mounted to the panel. The panel is attached to the troffer with a hinge connection. In this manner, the panel can be rotated away from the troffer for easy access.

  • Patent number: 10111392
    Abstract: A system and method for providing light to a plant with a life cycle that includes a seedling growth period, a vegetative growth period, and a flowering growth period. Illumination to the plant is provided with an array of LEDs that contains red LEDs, blue LEDs and white LEDs. During the seedling growth period, no red LEDs are illuminated. Blue and white LEDs are lit, wherein the blue light is more intense than the white. During the vegetative growth period, white and blue LEDs are lit, wherein the white light is more intense than the white. During the flowering growth period, red and white LEDs are lit, wherein the red light is more intense than the white light. The change in coloring and intensity has beneficial effects during each growth period and at the same time inhibits insects.

  • Publication number: 20170030553
    Abstract: A lighting fixture that minimizes light pollution in the blue frequencies of the visible spectrum. The lighting fixture contains a plurality of LEDs in an array. The array emits light with a first spectral profile. Most of the LEDs in the array have a correlated color temperature of between 2200K and 6500K, with a preferred value under 5000K. The light from the array passes through a filter. The filter removes much of the fractals of light between 400 nm and 500 nm so that the fractals between 400 nm and 500 nm account for no more than two percent of the overall intensity of the light. However, the filter decreases the intensity of light between 550 nm and 750 nm by no more than ten percent. This produces a light fixture that is highly energy efficient, has a high CRI index, and emits very low levels of light in the blue wavelengths of the spectrum.

  • Patent number: 9488351
    Abstract: A system and method of converting a light fixture from a conventional light fixture to an LED light fixture. Originally, the light fixture has a sheet metal troffer, a power supply, and receptacles for retaining bulbs. The conversion is accomplished in the following manner. A circuit board assembly is provided that has a plurality of LEDs mounted thereon. An LED power supply is also provided. The original power supply is replaced with the LED power supply. The circuit board assembly is directly mounted to the sheet metal troffer, which acts as a heat sink.

  • Patent number: 8727566
    Abstract: A system and method of converting a light fixture from a fluorescent light fixture to an LED light fixture. Originally, the fluorescent light fixture has a sheet metal troffer, a fluorescent light power supply, and receptacles for retaining fluorescent tube lights. The conversion is accomplished in the following manner. A circuit board assembly is provided that has a plurality of LEDs mounted thereon. An LED power supply is also provided, as is thermally conductive adhesive. The fluorescent light power supply is removed from the light fixture and the LED power supply is installed in its place. The circuit board assembly is directly mounted to the sheet metal troffer with thermally conductive adhesive. The circuit board assembly is then connected to the LED power supply and the light fixture is ready for use.

  • Patent number: 8579467
    Abstract: A lighting assembly where the light from multiple LEDs is blended to provide uniform lighting over a wide area without bright spots or interference anomalies. The assembly has a metal base that defines a channel. The channel has a bottom surface and opposing side walls. An array of LEDs is mounted on a circuit board. The circuit board is mounted to the bottom surface of the channel. A panel of light diffusing material is suspended over the LED array between the opposing side walls of the channel. The light diffusing material is configured to have lenticules that run parallel to the alignment of the LEDs. The lenticules vary between regions of the panel. Light emitted by the LED array passes through, and is diffused by, the lenticules. The result is a uniform patch of light that does not have bright areas or dark areas.

  • Publication number: 20070081342
    Abstract: A light emitting diode (LED) array that is configured to minimize heat damage to the LEDs during both the manufacturing of the array and the use of the array. The LED array utilizes a circuit board. The top surface of the circuit board contains a mounting area for retaining a light emitting diode. A plurality of separate thermal conduits extend through the circuit board within the mounting area. A light emitting diode is mounted to the top surface of the circuit board within the mounting area. The light emitting diode is contacted by the plurality of thermal conduits. The thermal conduits conduct heat away from the LEDs as the LEDS are in operation. Furthermore, the plurality of thermal conduits can be created with little or no thermal shock to the LEDS.
