Abstract
An LED driving circuit, adapted to drive an LED module, is disclosed. The LED driving circuit comprises a converting circuit, a converting controller, and a short-circuit protection circuit. The converting circuit, having a capacitor coupled to the LED module, is coupled to an input power source to proceed converting operation to supply an output current for driving the LED module. The converting controller controls the converting circuit to provide a stable current flowing through the LED module. The short-circuit protection circuit is coupled to the LED module in series and cuts the current flowing through the LED module off when detecting that the current higher than a current protection value.
