Abstract
A light emitting diode (LED) driving apparatus includes: a first circuit connected to a primary winding of a transformer, and configured to receive input power and transfer the input power to the primary winding of the transformer; a second circuit connected to a secondary winding of the transformer to generate output power for driving a plurality of LEDs; and a controller including a control circuit configured to control the second circuit, and a power detection circuit configured to compare a magnitude of the input power with a predetermined reference power magnitude range, and transmit a control command to the control circuit in response to determining that the magnitude of the input power is outside the predetermined reference power magnitude range.
