Method and device for remote sensing and control of LED lights

A method of thermal management for an LED, the method comprising:

• sensing a first thermal operating point of the LED;
• generating a temperature signal indicative of the first thermal operating point;
• receiving a rectified signal from a first transformer, the rectified signal indicative of a rectified power output by the first transformer;
• receiving the rectified power output from the first transformer;
• converting the rectified power output into a regulated power output, the rectified power output having one of a first frequency component or a second frequency component;
• responsive to receiving the rectified signal from the first transformer, determining that the first transformer is one of a magnetic transformer having the first frequency component or an electronic transformer having the second frequency component;
• determining a thermal operating range of the LED;
• responsive to receiving the temperature signal from the temperature sensor and determining the thermal operating range of the LED, determining that the first thermal operating point of the LED is outside the thermal operating range of the LED;
• and
• generating a control signal configured to calibrate the regulated power output whereby the LED is driven within the thermal operating range.

A thermal-management system for an LED, the system comprising:

• a temperature sensor configured to sense a first thermal operating point of the LED and generate a input signal indicative of the first thermal operating point;
• a processing device having a communications bus and configured to receive the input signal from the temperature sensor and a rectified signal from a first transformer, the rectified signal indicative of a rectified power output by the first transformer;
• a regulator IC having a power input link configured to receive the rectified power output from the first transformer, and a power output link, the regulator IC configured to convert the rectified power output into a regulated power output, the rectified power output having one of a first frequency component or a second frequency component;
• and
• an input/output link coupling the processing device to the regulator IC;
• wherein
• the processing device is configured to:
• sample the rectified signal over a period of time;
• responsive to sampling the rectified signal from the first transformer, determine that the first transformer is one of a magnetic transformer having the first frequency component or an electronic transformer having the second frequency component, and generate a first control signal to instruct the system to operate in one of a first mode or a second mode, the first mode compatible with the magnetic transformer wherein the processing device is responsive to a zero crossing duty cycle of the rectified signal, the second mode compatible with the electronic transformer wherein the processing device tracks a waveform of the rectified signal;
• determining a thermal operating range of the LED;
• responsive to receiving the input signal from the temperature sensor and retrieving the thermal operating range of the LED, determine the first thermal operating point of the LED is outside the thermal operating range of the LED;
• and
• generate a second control signal configured to calibrate the regulated power output whereby the LED is driven within the thermal operating range.
