  • Patent number: 8322011
    Abstract: A method for integrating at least one very high output (VHO) fluorescent lamp and at least one ballast within at least one fluorescent lamp fixture sealed from the growing environment is disclosed. The at least one ballast is secured within an upper fixture structure between a first cooling duct and a second cooling duct. At least one mid-plate reflector is mounted within the at least one upper fixture structure enclosing the at least one ballast thereby defining an upper chamber and a lower chamber. The at least one fluorescent lamp is installed in the lower chamber that is sealed from the growing environment by a transparent glass sheet, mounted to either or both the endplates or upper fixture structure. At least one fan is installed to the first cooling duct or the second cooling duct to provide the forced air cooling.

  • Publication number: 20120212883
    Abstract: A electronics enclosure that includes essentially two parts, a backing plate and a cover, the backing plate constructed of one sheet of metal having a top lip, a flat plate, a bottom step, a right side, and a left side whereby the top lip and bottom step define an air gap between the flat plate and a mounting surface; the cover constructed of one sheet of metal having a mounting tab, a top cover portion that has an angle between 10 degrees to 45 degrees from flat as defined by the ground, a flat front portion, a bottom portion, a bottom attachment tab and a plurality of fold over edges; the cover constructed and arranged to fit over the backing plate thereby providing a water shedding enclosure for electronics.

  • Patent number: 8209912
    Abstract: A horticulture light system comprising a housing, glass retention rails, gasket, glass sheet, and threaded fasteners. The housing constructed of no more than three portions of sheet metal, defining an interior space therein and having an open end towards the plants, the housing interior space constructed and arranged for containing a grow lamp and reflector to project a pattern of light out the open end of the housing at the plants, the open end including a rectangular sealing face for mating with the gasket, the gasket sealing the glass surface to the rectangular sealing face when compressed by the glass retention rails. The glass retention rails also constructed from sheet metal, easily formed into a L shape, attached by common threaded screws, and as tightened, compressively secure the glass to the gasket and housing. Loosening the threaded screws removes the compressive force, unsealing the glass from the housing, making for easy glass removal, facilitating maintenance and cleaning.

  • Patent number: 7641367
    Abstract: A horticulture light fixture having a secure glass aperture and glass retention frame that is swingably hinged to provide easy and safe maintenance of the fixture and helps facilitate cleaning of the glass. The hinge portion is constructed from sheet metal that is formed during the fabrication of the fixture. The method of construction eliminates the need to install a separate hinge saving manufacturing time and expense. In a preferred embodiment, the glass retention frame is constructed from a single continuous sheet of metal, that is punched or cut into desired dimension and shape, formed or folded to hold a flat piece of glass, and installed using common pins that provide rotational motion for swingably opening and closing of the glass simplifying maintenance of the horticulture light fixture.

  • Publication number: 20090116250
    Abstract: A lamp socket assembly for increasing cooling efficiency by reducing cooling air turbulence in a horticulture light fixture comprising a lamp socket capable of receiving a grow lamp, and an aerodynamic structure, said lamp socket and aerodynamic structure being positioned and attached within the horticulture light fixture to facilitate the aerodynamic structure splitting the cooling stream of air around the lamp socket and grow lamp reducing cooling air resistance, turbulence, and disturbance, thus increasing cooling efficiency.

  • Patent number: 7524090
    Abstract: A horticultural light system integrating a grow lamp and lamp ballast within a single fixture. The grow lamp is enclosed by the lower exterior structure and benefits from cooling atmosphere that is forced through the lower exterior structure to regulate the grow lamp temperature. The lamp ballast is mounted to a ballast plate above the lower exterior structure. The ballast plate shields the lamp ballast from the heated atmosphere as it rises off the top of the lower exterior structure. Stand offs or other separation means keep the ballast plate at a distance from the top of the lower exterior structure to create an air gap that thermally isolates the lamp ballast from the heat generated by the grow lamp, thereby increasing the reliability and life of the lamp ballast.
