LED lamp comprising a safety module for safe operation on various ballasts

摘要

The current invention relates to a LED lamp (10) comprising at least one LED light source (103), at least one driver (101) for powering the LED light source (103), at least one input rectifier with a plurality of diodes for converting an AC current from mains into a DC current, providing electrical power to the driver (101), the LED lamp (10) further comprising a safety module comprising one first and one second modules (F1, F2) for protection against overcurrent and overheating of the EM ballast, the first module (F1) being put in series with the driver (101) and designed to interrupt current in case the driver fails when the LED lamp (10) is directly connected to the mains, and the second module (F2) being designed to interrupt current when at least one of the diodes of the input rectifier fails when the lamp is connected to the mains via an EM ballast.
