Abstract

A light reflector frame has an upper wire frame and a lower wire frame each of generally rectangular form that are spaced apart and attached at an upper peripheral edge and a lower peripheral edge by a plurality of transverse brackets. At least four of the transverse brackets have a hook formed at a top end and a bottom end such that each of the hooks opens inwardly of the upper wire frame and the lower wire frame. At least one reflective panel is disposed inwardly of at least four transverse brackets to engage the hooks with a reflective surface of each reflective panel oriented inwardly of the transverse brackets. At least two pairs of opposed transverse brackets have an extended member at the top end positioned to extend upwardly over a cover of a horticultural lamp enclosure.

Claims

1. A light reflector structure for horticultural lamps comprising:

a light reflector frame has an upper wire frame and a lower wire frame each of generally rectangular form that are spaced apart and attached at an upper peripheral edge and a lower peripheral edge by a plurality of transverse brackets;

at least four of said plurality of transverse brackets have a hook formed at a top end and a bottom end wherein each of said hooks open inwardly of said upper wire frame and said lower wire frame;

at least one reflective panel is disposed inwardly of said at least four transverse brackets engaging said hooks with a reflective surface of each reflective panel oriented inwardly of said at least four transverse brackets; and

at least two pairs of opposed transverse brackets of said plurality of transverse brackets have an extended member at said top end disposed to extend upwardly over a cover of a horticultural lamp enclosure.

2. The light reflector structure as in claim 1 wherein there is disposed on said light reflector frame a first reflective panel on a first end, and second reflective panel on a second end, a third reflective panel on a first side, and a fourth reflective panel on a second side.

3. The light reflector structure as in claim 1 wherein said upper wire frame and said lower wire frame are attached by a corner transverse member at spaced apart adjacent corners.

4. The light reflector structure as in claim 1 wherein said at least one reflective panel is a trapezoid shape with a width of approximately one foot and a length of one of a first end, a second end, a first side, and a second side of said light reflector frame.

5. The light reflector structure as in claim 1 wherein said upper wire frame is sized to be the approximate shape of said cover peripheral edge.

6. The light reflector structure as in claim 1 wherein said light reflector frame is shaped such that said at least one reflective panel when disposed inwardly is positioned at an angle A relative to a vertical centerline of said cover of between 0 degrees and 90 degrees.

7. The light reflector structure as in claim 2 wherein said first reflective panel is positioned at a first angle A relative to a vertical center line of approximately 12 degrees, said second reflective panel is positioned at a second angle A of approximately 32 degrees, said third reflective panel is positioned at a third angle A of approximately 25 degrees, and said fourth reflective panel is positioned at a fourth angle A of approximately 25 degrees.

8. The light reflector structure as in claim 1 wherein:

each of said hooks at each of said top ends of each of said plurality of transverse brackets are curved outwardly at a hook end to be spaced apart from said transverse brackets; and

each of said hooks at said top ends and each of said hooks at said bottom end are spaced apart to allow a top edge of one of said reflective panels to be first inserted in said hooks at said top ends and then to be lowered for insertion in said hooks at said bottom edge.

9. The light reflector structure as in claim 8 wherein each of said hooks at said bottom ends are curved outwardly at a hook end to be spaced apart from said transverse brackets.

10. The light reflector structure as in claim 1 wherein said light reflector frame is formed as four sections wherein:

each section has a corner transverse member attached between said upper wire frame and said lower wire frame;

each end and each side of said light reflector frame is separated at their approximate midpoint to form a plurality of upper frame ends and a plurality of lower frame ends;

there is at least one of said transverse brackets attached intermediate each of said corner transverse members and each of said upper frame ends and said lower frame ends of each of said sections; and

opposed said upper frame ends and opposed said lower frame ends are attached by a fastener.

11. The light reflector structure as in claim 10 wherein said fastener is a spring clip.

12. The light reflector structure as in claim 10 wherein said fastener is a generally oblong tubular clamp with a threaded screw.

13. The light reflector structure as in claim 1 wherein each of said extended members have curved ends oriented upwardly relative to said cover.

14. The light reflector structure as in claim 1 wherein each of said reflective panels is formed of a light weight fire resistant material with a reflective surface formed on one side.

15. The light reflector structure as in claim 14 wherein said light weight fire resistant material is a plastic corrugated sheeting material.

16. The light reflector structure as in claim 15 wherein said plastic corrugated sheeting material is a polypropylene copolymer material.

17. The light reflector structure as in claim 14 wherein said reflective surface is a coated diamond silver white Mylar material.

18. A light reflector structure for horticultural lamps comprising:

a light reflector frame has an upper wire frame and a lower wire frame each of generally rectangular form that are spaced apart and attached at an upper peripheral edge and a lower peripheral edge by a plurality of transverse brackets;

at least four of said plurality of transverse brackets have a hook formed at a top end and a bottom end wherein each of said hooks open inwardly of said upper wire frame and said lower wire frame;

at least one reflective panel is disposed inwardly of said at least four transverse brackets engaging said hooks with a reflective surface of each reflective panel oriented inwardly of said at least four transverse brackets; and

at least three of said plurality of transverse brackets have an extending member at said top disposed to extend upwardly over three sides of a horticultural lamp enclosure.
