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.
Claims20
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.
