Product details

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.

In the event of a power outage: Automatically switch to power supply

The control module detects a sudden drop in the mains voltage (typically below the rated voltage by 60%), and immediately triggers the switching mechanism, cutting off the mains power input and enabling battery power supply.

The conversion module adjusts the DC output from the battery to the voltage suitable for the LED lamp beads (such as DC12V/24V), driving the lamps to light up within milliseconds to ensure the continuity of lighting.
