3W ABS LED light Emergency Power Supply

Complete workflow (in two scenarios) The emergency driving workflow for LED lights is divided into two scenarios: "normal power supply" and "power supply interruption". The logic is clear and the operation is automated: Scenario 1: When the power supply is normal (normal mode) The power supply detection module confirms that the power supply is normal and sends a "power supply available" signal to the power switching module. The power switching module prioritizes the power supply path and the rectifier filter module converts 220V alternating current into low-voltage direct current. A portion of the direct current is directly supplied to the LED driving module to drive the LED lights to illuminate normally. The other portion of the direct current passes through the charging management module and charges the backup battery until it is fully charged and enters a trickle charge maintenance state. Scenario 2: When the power supply is interrupted (emergency mode) The power supply detection mo…
