DETAILED DESCRIPTION OF THE INVENTION

(9) Referring now to the drawings, and more particularly to FIG. 1, there is shown, a side view of a light fixture 10 having an electrical connection 12, in the form of wiring 12, and a clamping area 14. Referring to FIG. 2 there is shown light fixture 10 in an exploded view, in which upper portion 16 and lower portion 18 are shown along with a screw 20. Light fixture 10 is designed to produce a large amount of light for the growing of plants. The intensity of the light emanating from light fixture 10 is such that cooling of the light producing element 22 is needed.

(10) Now, additionally referring to FIG. 3 there is shown a pipe 24, with light fixture 10 clamped thereto using clamping area 14 to encompass more than half of the circumference of pipe 24. The presence of pipe 24 allows for a transfer of heat from light producing element 22 to thereby allow light producing element 22 to more effectively produce the needed level of light. The thermal coupling from element 22 to pipe 24 is not illustrated, but it is such that the thermal resistance is low effecting efficient heat transfer. Water flowing in pipe 24, perhaps for irrigation purposes, allows for the warming of the water and the cooling of element 22. It is also contemplated that the fluid flow in pipe 24 could be a cooling fluid circulated through pipe 24 just to cool light elements 22.

(11) Now, additionally referring to FIG. 4 there is shown a side view, with pipe 24 shown in cross section to illustrate the clamping of fixture 10 to pipe 24.

(12) Now, additionally referring to FIGS. 5 and 6 there are shown the ease at which the spacing of multiple light fixtures 10 on pipe 24 can be arranged. Although not illustrated light fixtures 10 can be positioned at any rotative angle before screw 20 is tightened to alter the light direction. Light fixtures 10 can be spaced at selected distances along pipe 24.

(13) Advantageously, the present invention serves to keep lighting element 22 cool while pipe 24 carries water in the irrigation system.

(14) FIGS. 5 and 6 illustrate lighting systems that have lighting fixtures 10 coupled to cooling pipe 24, which can be irrigation pipe 24. Each lighting fixture 10 has an open sided pipe coupling portion 16, 18. Lighting member 22 is connected to coupling portion 16, 18, with lighting member 22 is thermally coupled to inside portion 14 of pipe coupling portion 16, 18. The lighting member 22 has light emanating away from cooling pipe 24.

(15) Cooling pipe/water irrigation pipe 24 can be a fluid circulating pipe 24 that conducts heat from light 22 by being thermally conducted by way of first member 18 to pipe 24. Pipe coupling portion 16, 18 has an opening 14 that has a C-shape. Pipe coupling portion 16, 18 extends more than halfway around the cooling pipe 24 when coupled thereto, as can be seen in FIG. 4. Pipe coupling portion 16, 18 includes first element 18 coupled to lighting member 22 and a second element 16 that is detachable from first element 18. Together first element 18 and second element 16 form C-shaped opening 14. First element 18 and second element 16 individually each extend less than halfway around cooling pipe 24. Fastening element 20 connects first element 18 and second element 16. Lighting member 22 has a substantially longitudinal symmetry, as can be seen in the drawings.

(16) While this invention has been described with respect to at least one embodiment, the present invention can be further modified within the spirit and scope of this disclosure. This application is therefore intended to cover any variations, uses, or adaptations of the invention using its general principles. Further, this application is intended to cover such departures from the present disclosure as come within known or customary practice in the art to which this invention pertains and which fall within the limits of the appended claims.
