MODIFIED LED LAMP WITH BYPASS CAPACITORS, PARALLEL RECTIFYING DIODES FOR USING WITH BALLAST Russian patent published in 2017 - IPC H05B33/08 

FIELD: lighting.

SUBSTANCE: lamp includes the LED load (LS), containing a series connection of the LEDs, the first circuit of the lamp end, containing the first lamp contact (LP1) and the second lamp contact (LP2) for connecting to the first terminal of the lamp contact, including in the high frequency ballast of the fluorescent lamp, the first rectifier (D1-D4; D1, D2), equipped with at least one input terminal, connected to the second lamp contact and also to the first and the second output terminals connected to respective ends of the light-emitting diode loading, wherein the first rectifier consists of at least two diodes, one of which is bypassed by the first capacitor (C1), the second circuit of the lamp end, containing the third lamp contact (LP3) and the fourth lamp contact (LP4) for connecting to the second terminal of lamp contact, including in the high frequency ballast content of the fluorescent lamp, the second rectifier (D5-D8, D5, D6), equipped with at least one input terminal, connected to the fourth lamp contact, as well as with the first and the second output terminals, connected to the corresponding ends of the light-emitting diode loading, wherein the second rectifier contains at least two diodes, one of which is bypassed by the second capacitor (C2), wherein the first capacitor and the second capacitor form a serial connection, connected between the second lamp contact and the fourth lamp contact.

EFFECT: ability to provide the LED replacing lamp, having a relatively small number of components which can be directly connected to the lamp contact terminals of the fluorescent lamp ballast, preferably to the high frequency ballast of the fluorescent lamp, in order to replace the fluorescent lamp, and consume less power than the fluorescent lamp, for which the high frequency ballast of the fluorescent lamp was designed.
