20080205030 | Horticulture Light Fixture Having Integrated Lamp and Ballast - 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. | 08-28-2008 |
