Abstract

The present disclosure relates to a lighting fixture for use in connection with a swimming pool or spa. The lighting fixture includes a light source, and a detection device for detecting the presence of a bather in a pool or a spa. A microprocessor is in electrical communication with the detection device and the light source. The microprocessor adjusts an output of the light source when a bather is detected in the pool or the spa. The microprocessor could adjust the color of the light emitted by the light source when a bather is detected. Also provided is a bather condition/activity detection system which utilizes pool or spa devices to detect various bather conditions/activities such as bather ingress, egress, drowning, distress, etc.

First claim

What is claimed is:

1. A bather detection system for a pool or spa, comprising:
a pool or spa device positionable at least partially within water of a pool or spa;
an acoustic sensor associated with the pool or spa device and configured to sense underwater sound and produce a signal indicative of the underwater sound; and
a processor in communication with the acoustic sensor and configured to analyze the signal to determine at least one of bather ingress or egress in the pool or spa,
wherein the processor issues an instruction to perform an action upon the determination of at least one of bather ingress or egress in the pool or spa, and
wherein the pool or spa device comprises a floating wireless chemical sensor, the acoustic sensor connected to the floating wireless chemical sensor.

2. The bather condition/activity detection system of claim 1 , comprising a memory in communication with the processor.

3. The bather detection system of claim 1 , wherein the processor causes a speaker to sound an alarm upon the determination of at least one of bather ingress or egress in the pool or spa.

4. The bather detection system of claim 1 , further comprising a light source.

5. The bather detection system of claim 4 , wherein the processor causes the light source to change color upon the determination of at least one of bather ingress or egress in the pool or spa.

6. The bather detection system of claim 4 , wherein the processor causes the light source to flash upon the determination of at least one of bather ingress or egress in the pool or spa.
