Electronic circuit for protecting LED lighting from power surges, comprises analogue digital converter for measuring voltage, microprocessor for calculating overvoltage and modulator for pulsing voltage in event of power surge

摘要

The power supply voltage (7) is measured using an analogue to digital converter (ADC) (2, 3), a microprocessor unit (4) calculates the overvoltage value and a modulator (5) modifies the voltage by pulsing it so that it is kept at a safe level in the event of a power surge.
