Abstract

A lighted panel system for a tub wall comprising a light diffusing panel, a light source that illuminates the light diffusing panel, and a mounting structure that couples the light diffusing panel to the tub wall. The light diffusing panel comprises a formed transparent or translucent sheet to which the light source is mounted. The light source comprises a plurality of light emitting diode lamps mounted on a circuit board protected by a circular rubber boot that attaches to a rear surface of the light diffusing panel such that light rays are dispersed in a principally lateral direction, parallel to the wall of the tub. A plurality of the lighted panel systems are preferably installed side by side along the length of a tub wall at the water line, an arrangement that allows for continuous lighting coverage and creates a new ambient effect.

Claims

1. A lighted panel system for installation in a tub wall, comprising:

a) a light diffusing panel including a front surface and a rear surface;

b) a light source including a plurality of light emitting diode (LED) lamps mounted between said front and rear surfaces, said LED lamps oriented to direct light principally parallel to said rear surface to illuminate said panel; and

c) a mounting structure for coupling said light diffusing panel to the tub wall, said mounting structure including at least one conduit integrally formed with said light diffusing panel and extending rearwardly from said rear surface for coupling said light diffusing panel to the tub wall,

wherein said light diffusing panel and said at least one conduit together define at least one channel, and said at least one channel extends between said front and rear surfaces of said light diffusing panel, and

wherein said plurality of LED lamps are operably disposed inside said at least one channel between said front and rear surfaces.

2. A lighted panel system according to claim 1, wherein:

said LED lamps are oriented opposite each other.

3. A lighted panel system according to claim 1, wherein:

said front surface has a first side, a second side, and a plurality of grooves running from said first side to said second side such that said front surface defines a plurality of integrated tile portions.

4. A lighted panel system according to claim 1, wherein:

said rear surface has a recess running along the outer perimeter of said rear surface.

5. A lighted panel system according to claim 1, wherein:

one of said front surface and said rear surface is textured.

6. A lighted panel system according to claim 1, wherein:

said light diffusing panel between said front and rear surfaces is translucent.

7. A lighted panel system according to claim 1, wherein:

said light source further comprises a circuit board on which said LED lamps are mounted, and a driving circuit provided on said circuit board.

8. A lighted panel system according to claim 1, wherein:

at least one conduit is tubular, said tubular conduit includes a threaded portion, and said mounting structure includes a nut that engages with said threaded portion to clamp the tub wall between the rear surface of said panel and said nut.

9. A lighted panel system according to claim 1, wherein:

said light diffusing panel further comprises a plurality of diffusers attached to said front surface in line with said LED lamps and said tubular conduits such that said diffusers conceal said LED lamps and said tubular conduits.

10. A lighted panel system for installation in a tub wall, comprising:

a) a light diffusing panel including a front surface and a rear surface, said front surface having at least one groove defining a plurality of integrated tile portions along said front surface, and said rear surface having a recess running along an outer perimeter of said rear surface;

b) a light source comprising two light emitting diode (LED) lamps oriented opposite each other, said light source located between said front and rear surfaces in alignment with one of said grooves such that each of said two LED lamps is directed to illuminate a tile portion on either side of a respective groove; and

c) a mounting structure at which said light diffusing panel is adapted to be coupled to the tub wall, said mounting structure including at least one conduit integrally formed with said light diffusing panel and extending rearwardly from said rear surface for coupling said light diffusing panel to the tub wall,

wherein said light diffusing panel and said at least one conduit together define at least one channel, said at least one channel extending between said front and rear surfaces of said light diffusing panel, and

wherein said plurality of LED lamps are operably disposed inside said at least one channel between said front and rear surfaces.

11. A lighted panel system according to claim 10, wherein:

said light diffusing panel is made from a transparent or translucent sheet of plastic.

12. A lighted panel system according to claim 10, wherein:

said grooves are vertical and define four equally sized rectangular tile portions in said front surface.

13. A lighted panel system according to claim 12, wherein:

at least one of said front and rear surfaces is textured with a design pattern.

14. A lighted panel system for installation in a tub wall, comprising:

a) a rectangular light diffusing panel including a front surface and a rear surface;

b) a light source including a plurality of light emitting diode (LED) lamps mounted between said front and rear surfaces to illuminate said panel;

c) a plurality of tubular conduits provided at said rear surface and extending rearwardly therefrom, said tubular conduits each including an external threaded portion; and

d) a plurality of nuts that engage with the respective threaded portions of said tubular conduits to clamp said panel relative to said nuts about the tub wall,

wherein said plurality of LED lamps are operably disposed between said front and rear surfaces inside channels defined by said plurality of tubular conduits and said panel.
