## Abstract

An illuminated foot spa is provided. The foot spa has a surface which defines a basin for containing water and a pump magnetically driven by rotating magnets. A mount defines part of the surface and holds the pump against rotation. A coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of a magnetic field produced by the rotating magnets to produce a current in the coil that powers a plurality of lights operatively connected to the coil. The light conductivity associated with the mount permits the plurality of lights to be visible interiorly of the basin.

## Claims

### Claim 1

An illuminated mount used in a foot spa, the foot spa having a surface defining a basin for containing water, a pump magnetically driven by rotating magnets and held against rotation by the mount which also defines part of the surface, the improvement comprising:
a coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of a magnetic field produced by the rotating magnets to produce a current;
a plurality of lights operatively connected to and powered by the coil;
a plurality of platforms defined on the mount with a circuit board releasably received by one of the plurality of platforms and operatively coupling the coil to the lights;
a cover portion of the mount with a first set of receivers that engage plugs on the circuit board, and the circuit board has a second set of receivers that engage plug ends of a set of removable cords; and
wherein the mount is one of translucent or transparent to provide light conductivity to permit light from the plurality of lights to be visible interiorly of the basin.

### Claim 2 (depends on 1)

The mount according to claim 1, wherein the mount includes a receiver and the coil is releasably received by the receiver.

### Claim 3 (depends on 1)

The mount according to claim 1, wherein the coil is formed integrally with the mount.

### Claim 4

An illuminated mount used in a foot spa, the foot spa having a surface defining a basin for containing water, a pump magnetically driven by rotating magnets and held against rotation by the mount which also defines part of the surface, the improvement comprising:
a coil associated with the mount and disposed exteriorly of the surface of the basin and interiorly of a magnetic field produced by the rotating magnets to produce a current;
a plurality of lights operatively connected to and powered by the coil, where each of the lights is associated with one of a plurality of modules, each module including a pair of plugs and a clip, one of the modules including a circuit board; and
in use, the clip of each module is secured to a post of a set of the posts and the plurality of modules are plugged together; and
wherein the mount is one of translucent or transparent to provide light conductivity to permit light from the plurality of lights to be visible interiorly in the basin.
