  • 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.

  • Publication number: 20080117617
    Abstract: A horticultural light fixture for reducing the temperature impact of the light source on growing plants, including a hollow sheet metal tube, having first and second round hollow ends and a cutaway portion on the underside open towards the plants with at least one lamp socket mounted within said metallic tube, locating the lamp over the cutaway portion, further including a reflector mounted within the metallic tube and extending out through the cutaway portion, constructed and arranged to deflect light from the lamp toward the plants, having a transparent portion fittingly attached to the reflector between the lamp and the plants being impermeable to the heated atmosphere while allowing light to pass through.
