  "textContent": "A circuit includes an emergency lighting system and an AC/DC converter. An output terminal of the emergency lighting system is electrically connected to a LED load, and the other output terminal LED_ON of the emergency lighting system is electrically connected to a switch S. The switch S is controlled by the emergency lighting system. The emergency lighting system includes an AC input detection module, a switching time detection module and a lithium battery. The AC input detection module is electrically connected to a neutral wire VN and a live wire VL. The switching time detection module is electrically connected between an output terminal of the AC input detection module and the LED_ON terminal. An output terminal of the AC/DC converter is electrically connected to a positive electrode of the lithium battery, and the other output terminal of the AC/DC converter is electrically connected to the LED load.",
