Abstract

The present invention is a view port suitable for installation under the water line of a vessel wherein the view port comprises a flange made from a corrosion resistant material and a body made from a heat resistant material. An alternative embodiment of the invention is an underwater light in which a high intensity light and ballast is completely installed into the above mentioned view port.

Claims

1. A thru-hull housing comprising:

an annular external flange having an annular opening,

a cylindrical, hollow main body removably attached to the external flange;

a lens sized to fit the annular opening of the external flange,

a means for securing the lens to the external flange,

a means for providing a watertight seal on both sides of said lens; and

a means for securing the housing to a vessel.

2. The thru-hull assembly of claim 1 wherein the means for securing the housing is selected from bonding, welding or mechanical fastening.

3. The thru-hull assembly of claim 2 wherein the mechanical fastening means is a locking ring.

4. The thru-hull assembly of claim 3 wherein the locking ring is used with a compression ring.

5. The thru-hull assembly of claim 1 wherein the means for securing the lens to the external flange is selected from bonding or mechanical fastening.

6. The thru-hull assembly of claim 5 wherein the mechanical means for securing the lens to the external flange is a glass retaining ring.

7. The thru-hull assembly of claim 1 where the means for providing a water tight seal is selected from sealants, o-rings, gaskets or mechanical seals.

8. The thru-hull assembly of claim 7 where the means for providing a water tight seal is a gasket.

9. The thru-hull assembly of claim 1 further comprising a cap threaded onto the distal end.

10. The thru-hull assembly of claim 9 further comprising a source of light.

11. The thru-hull assembly of claim 10 wherein the light is selected from halogen and metal halide.

12. The thru-hull assembly of claim 9 further comprising a camera.

13. The thru-hull assembly of claim 1 wherein the flange and the housing are comprised of two different metals.

14. The thru-hull assembly of claim 13 wherein the flange is selected of a highly corrosion resistant material.

15. The thru-hull assembly of claim 13 wherein the housing is comprised of a heat dissipating metal.

16. A thru-hull light comprising:

an annular external flange having an annular opening,

a cylindrical, hollow main body removably attached to the external flange;

a light housing removably attached to the main body,

a lens sized to fit the annular opening of the external flange,

a means for securing the lens to the external flange,

a means for providing a watertight seal on both sides of said lens disc; and

a means for securing the housing to a vessel.

17. The thru-hull light of claim 16 wherein the means for securing the housing is selected from bonding, welding or mechanical fastening.

18. The thru-hull light of claim 17 wherein the mechanical fastening means is a locking ring.

19. The thru-hull light of claim 18 wherein the locking ring is used with a compression ring.

20. The thru-hull light of claim 16 wherein the means for securing the lens to the external flange is selected from bonding or mechanical fastening.

21. The thru-hull light of claim 20 wherein the mechanical means for securing the lens to the external flange is a glass retaining ring.

22. The thru-hull light of claim 16 where the means for providing a water tight seal is selected from sealants, o-rings, gaskets or mechanical seals.

23. The thru-hull light of claim 22 where the means for providing a water tight seal is a gasket.

24. The thru-hull light of claim 16 wherein the lamp is selected from halogen or metal halide.

25. The thru-hull light of claim 16 further comprising a camera.

26. The thru-hull light of claim 16 wherein the flange and the housing are comprised of two different metals.

27. The thru-hull light of claim 26 wherein the flange is selected of a highly corrosion resistant material.

28. The thru-hull light of claim 26 wherein the flange is selected from stainless steel, bronze or titanium.
