DC
First Claim
1. A light bulb cooling device comprising:
- an outer tube comprisinga first end,a second end, anda transparent lower portion;
an inner tube comprisinga first end, anda second end;
a hollow first end cap comprisinga coolant fluid supply inlet port, andan air duct sleeve,such that the first end cap provides a seal between the first end of the inner tube and the first end of the outer tube;
a hollow second end cap comprisinga coolant fluid supply exit port, andan air duct sleeve,such that the second end cap provides a seal between the second end of the inner tube and the second end of the outer tube, so that an annular volume of coolant may be maintained between the inner tube, the outer tube, the first end cap, and the second end cap; and
at least one light bulb assembly positioned within the inner tube, such that at least a portion of the inner tube in proximity to the bulb is transparent.

Abstract
Water or air is directed through a hood or double cylinder cooling device for providing cooling to one or more light bulbs used in growing plants in greenhouses, aquarium, and hydroponic applications. A water recirculation system with a reservoir and a pump may provide a flow of cooling water through tubing to the hood. The hood provides a housing and a tube which contains one or more light bulbs which can be accessed or replaced through an end of the tube which projects through the housing. The light holder includes an enclosed electric box and a plurality of curved fins which expand against the inside glass tube. Various reflector housing shapes and reflectors direct light to plants. The end cap is bolted to a split ring flange attached to the outer tube.
