In an embodiment of a LED lighting system, the MCC effectuates a number of assessments of the voltage, at key intervals and locations along the said electric circuit, to determine where the voltage is adequate for the type of the load LED lighting source utilized, and whether there are any breaks in the current within the said electric circuit. Depending where along the electric circuit the break is diagnosed, the MCC can communicate with the different modules of the IPM and can instruct them to execute a specific function, such as either to replace the power source, or the DRV, or the LED lighting source.
In an embodiment of the invention, the MCC communicates with the other modules of the IPM directly. Hence, to obtain status information as to the quality of the current coming from power source, the adequacy of the current coming out of the IS, DRV, and the adequacy of the OS of the LED lighting source, the MCC communicates with the IS, the DRV, the OS and a LS mounted on the LED lighting source. From the connection of the power source to the IS, to the MCC measures the Input Voltage (Vin). Additionally, after an DRV is connected to a power source through IS, the MCC measures the Output Voltage (Vout) OS to determine whether the adequate voltage transformation took place and the appropriate/correct voltage level is transmitted to the LED lighting source. When the measurements of Vin and Vout are acceptable, the MCC commands the OS and permits the voltage to pass through to the LED lighting source by selecting one of the available LED lighting source.
