Abstract
A power source control method for a multi-module light-emitting diode (LED) circuit includes detecting a signal characteristics value according to a plurality of switching signals, being used for controlling the conduction of currents in the plurality of lighting modules, comparing the signal characteristics value with a pre-determined value to generate a comparing result, and outputting the comparing result to an external power supply device, such that the external power supply device can adjust the voltage level of an input voltage of the multi-module LED circuit according to the comparing result.
