Abstract

A directional lighting fixture can receive an elongated lamp. The fixture has a spaced pair of connective devices each having a barrel with an electrical contact adapted to connect to opposite ends of the lamp. A tubular lamp cover has a light transmissive section and a light reflective section. Each section is contiguous to the other and trough-shaped. The lamp cover is rotatably mounted around the barrels of the connective devices.

Claims

1. A directional lighting fixture adapted to receive an elongated lamp, said fixture comprising:

a spaced pair of connective devices each having a barrel with an electrical contact adapted to connect to opposite ends of said lamp; and

a tubular lamp cover having a light transmissive section and a light reflective section, each being contiguous to the other and trough-shaped, said lamp cover being rotatably mounted around the barrels of the connective devices.

2. A directional lighting fixture according to claim 1 wherein said light reflective section extends over a greater circumferential portion of said lamp cover than said light transmissive section.

3. A directional lighting fixture according to claim 1 comprising:

a pair of collars rotatably mounted on said barrels of said pair of connective devices, said lamp cover being mounted around said collars to rotate therewith.

4. A directional lighting fixture according to claim 3 wherein the barrel of each of said connective devices has a circumferentially spaced plurality of longitudinal ridges, said pair of collars each having a plurality of internal striations for engaging said longitudinal ridges.

5. A directional lighting fixture according to claim 3 wherein said lamp cover and said pair of collars are rotatable in unison through at least 180°

.

6. A directional lighting fixture according to claim 3 wherein said lamp cover and said pair of collars are rotatable in unison through 360°

.

7. A directional lighting fixture according to claim 3 wherein said light reflective section has a pair of longitudinal lips, said pair of collars each having a pair of longitudinal grooves sized to receive said pair of longitudinal lips.

8. A directional lighting fixture according to claim 7 wherein said light transmissive section has a pair of longitudinal channels adapted to hold said pair of longitudinal lips of said light reflective section.

9. A directional lighting fixture according to claim 8 wherein said light reflective section is longer than said light transmissive section.

10. A directional lighting fixture according to claim 1 wherein said light reflective section has a pair of longitudinal lips, said pair of collars each having a pair of longitudinal grooves sized to receive said pair of longitudinal lips, said light transmissive section having a pair of longitudinal channels adapted to snap onto said pair of longitudinal lips of said light reflective section.

11. A directional lighting fixture according to claim 1 wherein said light transmissive section is diffusive.

12. A directional lighting fixture according to claim 1 wherein each of said connective devices has a casing, said barrel extending longitudinally from said casing and having a circumferentially spaced plurality of longitudinal ridges, said casing having a stub spaced from and extending in the same direction as said barrel.

13. A directional lighting fixture according to claim 12 comprising:

a tubular housing mounted on the stub of each of said pair of connective devices to mechanically interconnect them.

14. A directional lighting fixture according to claim 13 wherein the tubular housing has a gutter-shaped surface facing said lamp cover.

15. A directional lighting fixture according to claim 13 wherein the electrical contact of each of the connective devices are adapted to connect to fluorescent lamps.

16. A directional lighting fixture according to claim 15 wherein the electrical contact of each of the connective devices are twist type.

17. A directional lighting fixture according to claim 15 wherein the tubular housing has a manually operable electrical switch.

18. A directional lighting fixture according to claim 12 wherein at least one of said connective devices has a power connector.

19. A directional lighting fixture according to claim 1 comprising a male and a female power connector separately mounted on respective ones of said connective devices.
