DESCRIPTION OF THE PREFERRED EMBODIMENT
With reference now to the drawings, and in particular to FIG. 1 thereof, the preferred embodiment of the new and improved underwater lighting system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the underwater lighting system 10 is comprised of a plurality of components. Such components in their broadest context include an underwater housing with a lens, a reflector, a bulb and an electrical ballast. Such components also include above ground electrical components. Such components are individually configured and correlated with respect to each other so as to attain the desired objective.
First provided is a housing 14. The housing has a circular open top 16. The housing has a circular closed bottom 18. The housing has a cylindrical side wall 20. The side wall is provided between the top and the bottom. The housing forms a chamber 22. The chamber is provided interiorly. The housing includes an annular lower flange 24. The lower flange extends radially outwardly from the top. The lower flange has eight holes 26. The holes are equally spaced around the circumference of the lower flange. The lower flange has an upper face 28. The upper face terminates interiorly at the chamber and externally at the lower flange. The upper face has an annular recess 30. The recess is provided around the entire upper face. The housing is molded of an elastomeric material. The elastomeric material is selected from the class of elastomeric materials. The class of elastomeric materials includes plastic and rubber, natural and synthetic, and blends thereof. The housing has small spherical lead weights 90. The weights are positioned in the bottom of the housing. In this manner the weight of the housing is increased for submersing purposes when beneath the water.
A lens 36 is provided. The lens is in an upwardly extending hemispherical configuration. The lens has an annular upper flange 38. The lens has an upper face 40. The lens has a lower face 42. The lower face of the lens is in mating contact with the upper face of the lower flange. An O-ring 44 is provided. The O-ring is received within the recess between the faces. The lens is fabricated of a transparent material. The transparent material is selected from the class of transparent materials. The class of transparent materials includes glass and plastic.
Provided next is a pressure ring 48. The pressure ring is in an annular configuration. The pressure ring has an upper face. The pressure ring has a lower face. The lower face of the pressure ring is in contact with the lower flange of the housing. The upper flange of the pressure ring has eight holes 52. The holes are equally spaced around the circumference of the pressure ring. The holes are aligned with the holes of the lower flange. Bolts 54 are provided. The bolts extend through the holes of the lower flange and pressure ring. Wing nuts are provided. The wing nuts facilitate coupling.
A socket assembly 58 is provided within the housing. The socket assembly is provided within the chamber at an intermediate elevation. The socket assembly includes a base 60. Bolts 62 are provided. The bolts secure the base. The socket assembly also includes projections 64. The projections terminate in spaced light sockets 66. The projections terminate at an elevation adjacent to the top of the housing.
A reflector 70 is provided next. The reflector is in a downwardly extending hemispherical configuration within the chamber. The reflector is coupled to the socket assembly by a central bolt 71. The reflector has spaced apertures 72. In this manner passage of the light sockets through the reflector is allowed.
Further provided is an elongated metal halide bulb 76. The bulb has opposed ends. The bulb is removably received within the light sockets of the socket assembly. The bulb is adapted to be replaced without contacting the reflector.
Provided next is the electrical ballast with laterally extending ledges located on the bottom of the housing. Small spherical weights are poured into the housing on the ledges of the electrical ballast to hold down the electrical ballast and the entire housing underwater.
Provided last are electrical components. The electrical components include a control station 80. The electrical components include wires 82. The wires have upper ends. The upper ends of the wires are coupled to the control station. The wires have lower ends. The lower ends of the wires are coupled to the electrical ballast and the light sockets. Split rings 83 with ties are coupled to the wire between the upper and lower ends to abate floating of the wire. The control station has a ground fault circuit interrupter 84, a dock electrical outlet 86, a timer 90 and a light sensor 92. The lower end of the wires has a compression washer 94 and an O-ring 96. In this manner the wire may be coupled to the housing.
The preferred source of illumination is a lamp which emits UV-A in the range of ultra violet light between 320 and 400 nanometers and designed to peak at 360 nanometers. Such light has been shown to stimulate retinal reactivity in non-mammalian organs. UV-A is the light spectrum region that causes pigment to darken in human and other mammalian cells but is invisible to species in that group. Primarily fish, insects and some invertebrates are able to visibly detect UV-A in nature, but some birds may have the ability, as well.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
