LIGHT-EMITTING DIODE DRIVING DEVICE, DRIVING METHOD AND LIGHT-EMITTING DIODE LIGHTING MODULE COMPRISING SAME

摘要

A light-emitting diode driving device capable of simultaneously implementing an excellent heat-dissipation function and high-efficient driving is disclosed. The disclosed LED driving device comprises: a power source unit for providing an alternate current voltage; a rectification unit for rectifying the alternate current voltage from the power source unit; a driving signal generation unit for generating a primary driving signal by using the rectified voltage from the rectification unit; and an LED driving signal modulation unit for generating a secondary pulse driving signal by modulating the primary driving signal, wherein a LED group is driven by the secondary pulse driving signal.
