CONTROL CIRCUIT OF LIGHT-EMITTING DIODE LIGHTING APPARATUS

摘要

Disclosed is a control circuit of a light-emitting diode lighting apparatus having a dimming function, wherein the control circuit of a light-emitting diode lighting apparatus provides, in response to a voltage commutation, a current path corresponding to the light-emitting state of a light-emitting channel, and implements dimming by controlling the amount of current in the current path in accordance with a dimming control signal provided as an analog or a digital signal.
