Lighted waterfall device

1. A waterfall apparatus for producing an artificial waterfall comprising:

a) a waterfall outlet for producing a waterfall, the waterfall outlet being on a front end of the waterfall apparatus, the waterfall outlet terminating in a horizontal waterfall slot through which water emanates from the waterfall apparatus, the waterfall slot also being on the front end of the waterfall apparatus and having a horizontal width relative to the front end;

b) a lighting unit;

c) a chamber for containing the lighting unit, wherein the chamber is located immediately below the waterfall slot, the chamber having a horizontal width also relative to the front and that is substantially the same as the waterfall slot width and wherein the chamber has at least one side located between the chamber and the waterfall slot that is a material that allows light from the lighting unit to act upon the waterfall by lighting at least one of water flowing through the waterfall slot and water emanating from the waterfall slot; and

d) a port to the chamber for accessing the lighting unit, wherein the port is located through and accessible from the front end of the waterfall apparatus, and wherein the port is separate from the waterfall slot whereby the chamber is not in fluid communication with the waterfall outlet and the waterfall slot.

2. The waterfall apparatus as claimed in claim 1 , wherein the at least one side of the chamber is a material selected from the group consisting of clear, transparent, translucent, and semi-transparent materials.

3. The waterfall apparatus as claimed in claim 2 , wherein the waterfall slot and the chamber are located at a position on the front end of the waterfall apparatus such that the waterfall that emanates through the waterfall slot, out of the waterfall outlet, falls directly into a spa tub.

4. The waterfall apparatus as claimed in claim 2 , wherein the lighting unit has a length that is substantially the same length as the chamber length.

5. The waterfall apparatus as claimed in claim 4 , wherein the lighting unit has a connector that cooperates with a connector on the waterfall apparatus whereby the lighting unit can be connected to and disconnected from the connector on the waterfall apparatus for removing the lighting unit from the waterfall apparatus and installing a different lighting unit into the waterfall apparatus.

6. The waterfall apparatus as claimed in claim 5 , wherein the lighting strip and the connector is accessible through the port.

7. The waterfall apparatus as claimed in claim 4 , wherein the lighting unit is a strip of light emitting diodes.

8. The waterfall apparatus as claimed in claim 1 , wherein the waterfall outlet comprises a serrated edge or floor located at a position on the waterfall apparatus proximal to or at the waterfall slot at the front end of the waterfall apparatus such that the waterfall that emanates out of the waterfall slot flows over the serrated edge, wherein the serrated edge adds turbulence to the waterfall in a controlled manner to create a waterfall flow pattern, whereby light is dispersed through the waterfall flow pattern.

9. The waterfall apparatus as claimed in claim 3 , wherein the waterfall outlet comprises a serrated edge or floor located at a position on the waterfall apparatus proximal to or at the waterfall slot at the front end of the waterfall apparatus such that the waterfall that emanates out of the waterfall slot flows over the serrated edge, wherein the serrated edge adds turbulence to the waterfall in a controlled manner to create a waterfall flow pattern, whereby light is dispersed through the waterfall flow pattern.

10. A waterfall apparatus for producing an artificial waterfall comprising:

a) a waterfall outlet for producing a waterfall, the waterfall outlet being on a front end of the waterfall apparatus, the waterfall outlet terminating in a horizontal waterfall slot through which water emanates from the waterfall apparatus, the waterfall slot also being on the front end of the waterfall apparatus and having a horizontal width relative to the front end;

b) a lighting unit;

c) a chamber for containing the lighting unit, wherein the chamber is not in fluid communication with the waterfall outlet and the waterfall slot, wherein the chamber is located immediately below the waterfall and the waterfall slot, the chamber having a horizontal width also relative to the front and that is substantially the same as the waterfall slot width, wherein the chamber has at least one side located between the chamber and the waterfall slot that is a material that allows light from the lighting unit to act upon the waterfall by lighting at least one of water flowing through the waterfall slot and water emanating from the waterfall slot, and wherein the at least one side of the chamber is a material selected from the group consisting of clear, transparent, translucent, and semi-transparent materials; and

d) a port to the chamber for accessing the lighting unit, wherein the port is located through and accessible from the front end of the waterfall apparatus, and wherein the port is separate from the waterfall slot,

wherein the lighting unit has a length that is substantially the same length as the chamber length, and

wherein the lighting unit is accessible through the port.

11. The waterfall apparatus as claimed in claim 10 , wherein the chamber is oriented to run adjacent to the waterfall slot at the front end of the waterfall apparatus.

12. The waterfall apparatus as claimed in claim 11 , wherein the waterfall slot and the chamber are located at a position on the front end of the waterfall apparatus such that the waterfall that emanates through the waterfall slot, out of the waterfall outlet, falls directly into a spa tub.

13. The waterfall apparatus as claimed in claim 10 , wherein the lighting unit has a connector that cooperates with a connector on the waterfall apparatus whereby the lighting unit can be connected to and disconnected from the connector on the waterfall apparatus for removing the lighting unit from the waterfall apparatus and installing a different lighting unit into the waterfall apparatus.

14. The waterfall apparatus as claimed in claim 11 , wherein the waterfall outlet comprises a serrated edge or floor located at a position on the waterfall apparatus proximal to or at the waterfall slot at the front end of the waterfall apparatus such that the waterfall that emanates out of the waterfall slot flows over the serrated edge, wherein the serrated edge adds turbulence to the waterfall in a controlled manner to create a waterfall flow pattern, whereby light is dispersed through the waterfall flow pattern.

15. The waterfall apparatus as claimed in claim 12 , wherein the waterfall outlet comprises a serrated edge or floor located at a position on the waterfall apparatus proximal to or at the waterfall slot at the front end of the waterfall apparatus such that the waterfall that emanates out of the waterfall slot flows over the serrated edge, wherein the serrated edge adds turbulence to the waterfall in a controlled manner to create a waterfall flow pattern, whereby light is dispersed through the waterfall flow pattern.
