Abstract

An underwater light including a programmable controller and a replaceable light-emitting diode (LED) printed circuit board assembly (PCBA) is provided. The light includes a controller PCBA in communication with the LED PCBA, and a connector for connecting the controller PCBA to the LED PCBA. An optically-transparent potting compound encapsulates the LED PCBA, and the LED PCBA can be safely replaced by removing a rear housing of the underwater light.

First claim

What is claimed is:

1 . An underwater light, comprising:
a controller printed circuit board assembly (PCBA), including:
a microcontroller subsystem including a microcontroller,
a light-emitting diode (LED) driver subsystem in communication with the microcontroller subsystem, the LED driver subsystem receiving pulse-width modulated (PWM) signals from the microcontroller subsystem and being controlled by the PWM signals, and
a power subsystem providing power to the microcontroller subsystem and the LED driver subsystem;
an LED printed circuit board assembly (PCBA) in communication with the controller PCBA, the LED PCBA including a plurality of LED strings in communication with and driven by the LED driver subsystem; and a connector connecting the controller PCBA to the LED PCBA, the connector communicating LED drive signals between the LED driver subsystem and the plurality of LED strings.

2 . An underwater light, comprising:
a controller printed circuit board assembly (PCBA) including a microcontroller, the microcontroller generating pulse-width modulated (PWM) signals; an LED printed circuit board assembly (PCBA) in communication with the controller PCBA, the LED PCBA being replaceable and including a plurality of LED strings in communication with and driven by the microcontroller; and a connector connecting the controller PCBA to the LED PCBA, the connector communicating the PWM signals between the microcontroller and the plurality of LED strings.
