Distributed Photobiomodulation Therapy System And Method

A distributed photobiomodulation therapy (PBT) system comprising:

• a PBT controller, the PBT controller comprising a main microcontroller, a communication interface, a digital clock, and an LED pad identity data register;
• a light-emitting diode (LED) pad, the LED pad comprising:
• a pad microcontroller,
• a memory, the memory comprising a non-volatile memory,
• an array of light-emitting diodes (LEDs), the array of LEDs comprising one or more LED strings, the LEDs in each of the LED strings being connected in series,
• one or more LED drivers, each of the one or more LED drivers being connected to and for controlling a current in one of the LED strings, and
• a pad identity data register, the pad identity data register being stored in the non-volatile memory and comprising data for use by the PBT controller for authenticating the identity of the LED pad;
• and
• a communication link for carrying digital data between the PBT controller and the LED pad for controlling the current in and illumination of the one or more LED strings
• wherein the LED pad identity data register in the controller matches the LED pad identity data register in the LED pad as a result of the LED pad having previously sent an LED pad device ID to the controller as part of an authentication process.
