A DEVICE FOR SUPPLYING POWER TO LED DIODES
A device for supplying diodes LED includes an electric bridge (ABHG) with input terminals (A, B) and output terminals (H, G), including diodes (DS1, DS2) interposed between branches (AH, BH), with cathodes turned toward the terminal (H); Two MOSFET elements (M1, M2) are interposed between the branch...

| description | A device for supplying diodes LED includes an electric bridge (ABHG) with input terminals (A, B) and output terminals (H, G), including diodes (DS1, DS2) interposed between branches (AH, BH), with cathodes turned toward the terminal (H); Two MOSFET elements (M1, M2) are interposed between the branches (AG, BG). A capacitor (C) is derived between the terminals (H) and (G). A switch (KR) and LED diodes arranged in series, with their anodes oriented toward the terminal (H), and a first current sensor (S1) are arranged along a derived branch (R), between the terminals (H) and (G). An electric control unit (CE) receives in input feedback control signals coming from the first sensor (S1) and operates opening/closing of the switches (M1) and (M2), as well as of the branch switch (KR) in suitable relation with the trend of the alternating current (iz), to obtain a predetermined trend of the branch current (ir.) for power supplying the LED diodes. |
