1. A method of initializing an LED driver to power an LED light engine comprising one or more LEDs, the method comprising:
connecting a control terminal of the LED driver to a control terminal of the LED light engine;
determining whether the control terminal of the LED light engine is a communication terminal by outputting a communication signal from the control terminal of the LED driver to the control terminal of the LED light engine;
establishing that the control terminal of the LED light engine is a communication terminal if a reply communication signal to the communication signal is received within a predetermined period;
if the control terminal of the LED light engine is a communication terminal, perform an initialization of the LED driver by exchanging configuration data between the LED driver and the LED light engine;
if the control terminal of the LED light engine is not a communication terminal, determining an impedance value observed at the control terminal of the LED light engine and performing an initialization of the LED driver based on the impedance value.
