Programmable underwater lighting system

摘要

The present disclosure relates to a programmable underwater lighting system for pools and spas. A plurality of underwater lights, each having a plurality of LEDs for producing light of various colors, a microprocessor for controlling the plurality of LEDs, and a memory in communication with the microprocessor containing one or more stored control programs, allow for the generation of various lighting effects in a pool or spa. A central controller is provided in communication with the plurality of underwater lights, and allows a user to define or select a desired lighting effect (such as a sequence, a fading effect, a “moving” color pattern, etc.) using a display and a keyboard. Optionally, a handheld remote control could be provided, in wireless communication with the central controller, for allowing a user to remotely control the plurality of lighting fixtures. When a desired lighting effect is defined by a user, the central controller transmits an instruction to each of the plurality of underwater lights instructing each light to execute a specific stored control program in its memory to produce the desired lighting effect. Each of the lights could be in communication with the central controller using a power line and an associated power line carrier data protocol, and each light could be provided with a thermal management system for monitoring the operating temperature of the light and automatically adjusting the brightness of the light to prevent dangerous temperatures.

主权项

1. A programmable underwater lighting system, comprising:
an underwater lighting fixture for installation in a pool or spa, the underwater lighting fixture including a light source, a microprocessor in electrical communication with the light source, a memory having at least one stored control program executable by the microprocessor for controlling the light source, an alternating current (AC) power supply for supplying electrical power to the underwater lighting fixture, a logic power supply for supplying electrical power to the microprocessor, and a Power Line Carrier communications subsystem connected between the AC power supply and the logic power supply, and in electrical communication with the AC power supply, the logic power supply, and the microprocessor, and a central controller remote from and in communication with the underwater lighting fixture, the central controller allowing a user to specify a desired lighting sequence and transmitting an instruction to the underwater lighting fixture over a power line interconnecting the central controller and the underwater lighting fixture to selectively execute the stored control program to produce the desired lighting sequence, wherein the underwater lighting fixture receives the instruction from the central controller via the AC power supply using the Power Line Carrier communications subsystem and executes the instruction, and wherein prior to transmitting the instruction to the underwater lighting fixture the central controller authenticates the lighting fixture by communicating with the lighting fixture and determining whether the lighting fixture is authorized for use with the central controller.
