Horticulture grow light reflector

Horticulture grow light housing

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. The mid-plate reflector benefits from openings above the lamp location thereby providing a vent for heated air around the fluorescent lamp to rise up, away from the lamp, and out into the upper chamber where it is exhausted. The mid-plate reflector further benefits from being solid above the lamp ends or electrodes thereby retaining heat and improving lamp performance. At least one baffle located within the upper chamber directs cooling air provided by the fans through the mid-plate reflector to better cool the lamp, around the ballast to improve ballast cooling characteristics, or both.

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.

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.

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.
