Abstract

An underwater lighting device for use with a liquid container such as a swimming pool having a return line for returning water to the pool, the lighting device including a main support body for supporting light emitting diodes, the main support body having a fluid outlet and hollow spigot extending from the main support body for engagement with the return line such that fluid can flow from the return line through the outlet.

Claims

1. An underwater lighting device for use with a liquid container of the type having at least one return line for returning water to said liquid container, said lighting device including a main support body for supporting one or more light sources, and locating means for cooperation with said return line to locate said lighting device in said liquid container.

2. A lighting device as claimed in claim 1 wherein said support body has one or more water outlets through which water flowing through the return line can return to the liquid container.

3. A lighting device as claimed in claim 1 and including a wire or cable for supplying current to said light source, said wire or cable extending in use along said return line for connection to a power supply.

4. A lighting device as claimed in claim 1 wherein said support body supports a power supply whereby said lighting device is self contained.

5. A lighting device as claimed in claim 1 wherein said locating means comprise engagement means which are frictionally engageable with said return line.

6. A lighting device as claimed in claim 1 wherein said main support body has a liquid outlet for flow of water from the return line to the liquid container.

7. A lighting device as claimed in claim 6 wherein said main support body comprise a pool return fitting and said locating means comprises a spigot formed integrally with or fixed to the main body.

8. A lighting device as claimed in claim 7 wherein said spigot is of hollow tubular form and defines a flow passage for communicating the return line with the liquid outlet or outlets.

9. A lighting device as claimed in claim 1 wherein said main support body has a front face and wherein said light source is mounted on said front face.

10. A lighting device as claimed in claim 1 wherein said light source comprise at least one solid state light emitting device.

11. A lighting device as claimed in claim 10 wherein said light source comprises a plurality of light emitting diodes.

12. A multidirectional underwater lighting device for use in a liquid container, said lighting device comprising a light source support body for supporting a light source and a mounting portion for mounting said support body to said liquid container, said support body being movable relative to said mounting portion in a plurality of directions relative to said mounting portion.

13. A lighting device as claimed in claim 12 wherein said mounting portion is releasably engageable with a pipe or housing in a wall of the water container.

14. A lighting device as claimed in claim 13 wherein said support body and mounting portion comprise an eyeball pool return fitting, said support body comprising an eyeball of said fitting and said mounting portion comprising a spigot of said fitting.

15. A lighting device as claimed in claim 13 wherein said light source comprise a plurality of light emitting diodes mounted to said eyeball.

16. A lighting device including a housing adapted to be connected to a source of fluid, said housing having a fluid flow outlet for said fluid, and said housing supporting one or more light sources for illuminating fluid flow through said outlet.

17. A lighting device as claimed in claim 16 wherein said fluid outlet comprises one or more openings formed or defined in the housing.

18. A lighting device as claimed in claim 17 and including an engagement portion for mounting said housing to a fluid flow pipe.

19. A lighting device as claimed in claim 18 wherein said engagement portion comprises a spigot for releasable engagement with the fluid flow pipe.

20. A lighting device as claimed in claim 19 wherein said spigot is hollow and defines a fluid flow passage for communicating said fluid flow pipe with said outlet.

21. A lighting device as claimed in claim 16 and including means for mounting said housing to a wall.

22. A lighting device as claimed in claim 21 wherein said mounting means includes a threaded spigot for passage through an opening in said wall for engagement with a nut.

23. A lighting device as claimed in claim 16 wherein said light source comprise a solid state light emitting device.

24. A lighting device as claimed in claim 23 wherein said light source comprise a plurality of light emitting diodes arranged at a circumferential spacing around said fluid flow outlet.

25. A lighting device as claimed in claim 24 wherein said housing includes a front wall having a plurality of openings therein through which respective light emitting diodes project.
