Zusammenfassung:An LED driving circuit is provided. The LED driving circuit comprises a linear driving circuit, connected in series with a LED load to control a current flowing through the LED load; a first capacitor, connected in parallel with a serial structure consisting of the linear driving circuit and the LED load; and a control circuit, configured to control a voltage of the first capacitor to decrease a voltage difference between two terminals of the linear driving circuit, to increase an efficiency of the LED driving circuit. The LED driving circuit of the present disclosure reduces power consumption within the linear driving circuit, resulting in improved efficiency.
