Power Supplies For Pool And Spa Equipment
First Claim
Patent Images
1. A power supply for powering pool or spa equipment, comprising:
- a power supply unit external to a pool or a spa;
a first inductive power coupling including an inductor circuit, said first inductive power coupling in electrical communication with the power supply unit and at least partially embedded in a wall of the pool or spa;
a second inductive power coupling including an inductor circuit, said second inductive power coupling received by said first inductive power coupling in the pool or spa, wherein the inductor circuit of the first power coupling inductively transmits power from the power supply to the inductor circuit of the second inductive power coupling for powering a device in a pool or spa connected to the second inductive power coupling; and
a cable connected at a first end to the device and at a second end to the second inductive power coupling such that the second inductive power coupling is external to the device, the cable delivering electrical power to the device and permitting movement of the device relative to said first and second inductive power couplings while said second inductive power coupling is received by said first inductive power coupling.

Abstract
Power supplies for pool and spa equipment are disclosed. In one embodiment, the power supply includes a buoyant housing, a peripheral float, at least one solar cell positioned on the buoyant housing for collecting sunlight and converting same to electrical energy, and a power cable for interconnecting the power supply and pool/spa equipment. In other embodiments, first and second inductive power couplings are provided for powering pool and spa equipment. The power couplings can also be installed using existing plumbing features of the pool or spa.
