A metal oxide varistor (MOV) can help protect the LED bulb from overvoltage surges and ring-wave effectes by clamping short-duration voltage impulses. A TVS Diode on the dc side can be used to protect against transients before entry into converter circuit. Open circuit LED protection device TVS Diode Transient protection for energy let through
