"textContent": "Disclosed is a downlight power box control circuit capable of realizing emergency lighting and general lighting, comprising a battery, a logic input module and a light-emitting element which are electrically connected to a main control module. The logic input module determines whether a mains voltage is available. In a case where the mains supply supplies power normally, the main control module controls the light-emitting elements to operate according to 100% of a load power. In case of an outage of the mains supply, the battery is used to supply power to a light tube, and the control module controls the light-emitting element to operate according to 30%-50% of the load power to realize emergency lighting.",
