LED CONVERTOR LC FEEDBACK STABILIZATION CIRCUIT

The present invention relates to a LED convertor LC feedback stabilization circuit which prevents the deterioration of an LED lamp and fire damage by installing a leakage current detection circuit in the back end of a driving circuit and can prevent fire damage of a light emitting diode due to overvoltage and overcurrent. The present invention includes a transformer which generates the first load power of a secondary first coil by changing a primary power applied to a primary coil and the second load power of a secondary second coil, a photo coupler which controls a driving circuit which is connected to the secondary second coil to supply primary power and an on/off operation for connecting power supply parts which supplies power to the driving circuit, an overvoltage feedback circuit which compares two voltages applied to the high potential part of the second load power and the high potential part of the first load power and deactivates a light emitting part which sets the voltages of both ends of the light emitting part of the photo coupler when the comparison result is overvoltage, an overcurrent feedback circuit which detects the conduction current of an LED lamp driven by a fist load power and deactivates the light emitting part by forming a current path which bypasses when the comparison result is overcurrent.
