DISCHARGE CIRCUITRY DESIGN FOR PEAK CURRENT ELIMINATION OF EXCHANGEABLE MODULES

摘要

The invention describes a replaceable LED circuit for coupling to an LED driver. The replaceable LED circuit comprises a pair of input pins for receiving a power supplied by LED driver, an LED string coupled between the pair of input pins for receiving the power, and a surge protection circuit coupled in parallel to the LED string. The surge protection circuit comprises a capacitor arranged to charge when the power is supplied to the LED string, and a current regulator coupled in series with the capacitor and arranged such that it allows the capacitor to charge and prevents the capacitor to discharge into the LED string.
