LED LAMP COMPRISING A SAFETY MODULE FOR SAFE OPERATION ON VARIOUS BALLASTS Russian patent published in 2018 - IPC H05B33/08 

FIELD: electricity.

SUBSTANCE: invention relates to an LED lamp comprising a safety module. Result is achieved by the fact that LED lamp (10) comprises at least one LED light source (103), at least one driver (101) for supplying the LED of light source (103), at least one input rectifier with a plurality of diodes for converting the AC of the current from the electrical network into a DC current, providing a power supply to driver (101), LED lamp (10) further comprising a safety module comprising one first and one second modules (F1, F2) for protecting against excessive current and overheating of the EM ballast, first module (F1) is connected in series with driver (101) and is configured to interrupt the current in the event that the driver fails when LED lamp (10) is directly connected to the electrical network, and second module (F2) is configured to interrupt the current when at least one of the input rectifier diodes fails when the lamp is connected to the power grid via the EM ballast.

EFFECT: technical result is to ensure the safe operation of the LED lamp with various ballasts.
