2*3W LED Double Head Emergency Light

  The working principle and process of the LED lamp emergency power supply   The operation mechanism of the LED lamp emergency power supply can be divided into two stages: daily charging and emergency switching. Seamless transition is achieved through the automatic control of circuit modules.    When the mains power is normal: charging and standby mode    The charging module converts the mains power (or external power sources such as solar panels, USB, etc.) into direct current and charges the built-in battery until it is fully charged, then automatically enters the floating charge state.   The control module continuously monitors the battery voltage and current to ensure a safe and stable charging process and prevent overcharging or overdischarging.
