Abstract
A light-emitting diode (LED) device with afterglow-proof function includes a common positive electrode, a common negative electrode and a LED lighting module. The common positive electrode is connected to the positive electrode of an external power source. The common negative electrode is connected to the negative electrode of the external power source. One end of the LED lighting module is connected to the common positive electrode and the other end of the LED lighting module is connected to the common negative electrode. The LED lighting module includes a plurality of LED lighting units connected to each other in series. Each of the LED lighting units includes a light source and a capacitor connected to each other in parallel. The circuit design can realize the afterglow-proof function in order to prevent the afterglow effect of the LED lighting device.
