Light emitting diode driving system

Abstract

An exemplary light emitting diode driving system includes a protective circuit, a rectifying circuit, a driving circuit, a light emitting diode module and a detecting circuit. The protective circuit, the rectifying circuit, the driving circuit and the light emitting diode module are connected in series. The driving circuit is configured for driving the light emitting diode to emit light. The detecting circuit has predetermined voltages or current values stored therein. The detecting circuit detects the respective voltage or current of the protective circuit, the rectifying circuit and the driving circuit, and compares the respective voltage or current with the predetermined voltages or currents.
