description The present invention relates to a dimming angle sensing circuit and a driving method thereof. A dimming angle sensing circuit according to an exemplary embodiment of the present invention uses a zener diode. The dimming angle sensing circuit generates a comparison voltage according to a comparison result of a line voltage and a zener voltage. The line voltage is generated from rectification of an AC input passed through a dimmer. The dimming angle sensing circuit generates a sense voltage corresponding to a dimming angle of the dimmer by low-pass filtering the comparison voltage.
