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.

Claims (15)

1. The method for integrating a lamp ballast within a grow light fixture comprising the steps of:

a) enclosing the grow lamp in a lower exterior structure;

b) securing the lamp ballast to a ballast plate;

c) mounting said ballast plate to the top side of the lower exterior structure using at least one stand off spacer between the ballast plate and the lower exterior structure; and,

d) said stand off spacer being the size of the desired air gap between the ballast plate and the lower exterior structure.

2. A horticultural light system having an integrated lamp and ballast comprising:

an exterior structure having a lower exterior structure and a ballast enclosure;

said lower exterior structure having a lower flat front side, a lower flat rear side, a mid top flat side, and a rectangular bottom side being open towards the plants, including a cool atmosphere inlet on the flat front side, and a heated atmosphere exhaust outlet on the rear flat side;

said ballast enclosure having a front inclined upper portion, a rear inclined upper portion, a first inclined upper side portion, a second inclined upper side portion, and a flat top side, the bottom bounded by the mid top flat side of the lower exterior structure;

at least one vent cut through the ballast enclosure;

a light reflector hood within said lower exterior structure, constructed and arranged to reflect light towards plants, further having a first opening at the cool atmosphere inlet, and a second opening at the heated atmosphere exhaust outlet;

a transparent portion between the light reflector hood and the plants, fittingly attached to said lower exterior structure sealing the atmosphere within the light reflector chamber from the growing environment of the plants;

a lamp ballast integrated above said lower exterior structure and within said ballast enclosure, mounted to a ballast plate, said ballast plate fixedly attached to the mid top flat side of the lower exterior structure, leaving an air gap between said ballast plate and the mid top flat side;

at least one support socket bracket for mounting a lamp within the lower exterior structure.

3. The horticultural light apparatus of claim 2 , wherein the ballast plate is separated from the mid top flat side by a plurality of stand off spacers, said stand off spacers setting the air gap size between the ballast plate and mid top flat side.
