Zusammenfassung:	The utility model provides an LED lamp driving circuit. The LED lamp driving circuit and an LED bead board are installed directly together and are directly connected with commercial power. The LED lamp driving circuit comprises triodes Q1 and Q2 and constant-current resistors R1 and RS1. The base electrode of the triode Q1 is connected with the collector electrode of the triode Q2. The emitter electrode of the triode Q1 is connected with the base electrode of the triode Q2. One end of the resistor R1, the base electrode of the triode Q1, and the collector electrode of the triode Q2 are connected. The other end of the resistor R1 is connected with the collector electrode of the triode Q1. One end of the resistor RS1, the collector electrode of the triode Q1, and the base electrode of the triode Q2 are connected. The other end of the resistor RS1 is connected with the emitter electrode of the triode Q2. The LED lamp driving circuit can be installed on the LED bead board in an integrated manner, and has small si
