Abstract

A support and enclosure structure for fluorescent light bulbs includes an elongated, hollow tube having opposite ends, an outer wall and an inner volume, and at least one ventilation opening extending through the outer wall for permitting air flow between the inner volume of the tube and the surrounding environment for cooling of the fluorescent light bulb held there within. End caps are mounted on opposite ends of the tube, the end caps adapted to engage opposite ends of the fluorescent light bulb and support the fluorescent light bulb within the inner volume of the tube free of contact with the outer wall of the tube. Finally, the tube is constructed of a generally rigid, at least partially translucent materials, such that light emitted by the fluorescent light bulb held within the tube generally radiates through the outer wall of the tube into the surrounding environment.

Claims

1. A support and enclosure structure for fluorescent light bulbs comprising;

an elongated, hollow tube having opposite ends, an outer wall and an inner volume;

at least one ventilation opening extending through said outer wall and permitting air flow between said inner volume of said tube and the surrounding environment for cooling of a fluorescent light bulb held therewithin;

end cap means mounted on said opposite ends of said tube, said end cap means adapted to engage opposite ends of a fluorescent light bulb and support the fluorescent light bulb within said inner volume of said tube free of contact with said outer wall of said tube; and

said tube constructed of a generally rigid, at least partially translucent material such that light emitted by a fluorescent light bulb held within said tube generally radiates through said outer wall of said tube into the surrounding environment.

2. The support and enclosure structure for fluorescent light bulbs of claim 1 wherein said hollow tube is generally cylindrical in shape.

3. The support and enclosure structure for fluorescent light bulbs of claim 1 wherein said ventilation opening comprises a longitudinally extended slot formed in said outer wall of said hollow tube.

4. The support and enclosure structure for fluorescent light bulbs of claim 1 wherein said ventilation opening comprises a plurality of holes generally spaced along said hollow tube and extending through said outer wall.

5. The support and enclosure structure for fluorescent light bulbs of claim 1 wherein said end cap means each comprise a generally cylindrical plug having an external diameter approximately equal to or slightly greater than the internal diameter of said hollow tube, said generally cylindrical plug being generally hollow and having an electrode opening extending generally coaxially therethrough, said generally cylindrical plug further including a outer flange operative to prevent said end cap means from overextending into said hollow tube.

6. The support and enclosure structure for fluorescent light bulbs of claim 1 further comprising a wire channel formed in the outer surface of said outer wall of said hollow tube and extending along the length of said hollow tube, said wire channel operative to provide a channel for an electrode wire projecting from a fluorescent bulb housed within said hollow tube to run back along said hollow tube yet be safely retained adjacent said hollow tube to generally prevent accidental damage to an electrode wire.

7. The support and enclosure structure for fluorescent light bulbs of claim 1 further comprising mounting end cap means adapted to fit over said end cap means and on to said hollow tube facilitating mounting of said hollow tube within a fluorescent light fixture.

8. A support and enclosure structure for fluorescent light bulbs comprising;

an elongated, hollow tube having opposite ends, an outer wall and an inner volume;

at least one ventilation opening extending through said outer wall and permitting air flow between said inner volume of said tube and the surrounding environment for cooling of a fluorescent light bulb held therewithin;

end cap means mounted on said opposite ends of said tube, said end cap means adapted to engage opposite ends of a fluorescent light bulb and support the fluorescent light bulb within said inner volume of said tube free of contact with said outer wall of said tube;

mounting end cap means adapted to fit over said end cap means and on to said hollow tube facilitating mounting of said hollow tube within a fluorescent light fixture; and

said tube constructed of a generally rigid, at least partially translucent material such that light emitted by a fluorescent light bulb held within said tube generally radiates through said outer wall of said tube into the surrounding environment.

9. The support and enclosure structure for fluorescent light bulbs of claim 8 wherein said mounting end caps each further comprise at least one mounting pin and at least one wire slot formed in the side wall of said mounting end cap, said wire slot operative to permit electrical wires to extend therethrough to connect to the fluorescent light bulb held within said tube.
