The utility model relates to a direct current high-power energy-saving lamp controller which comprises a power supply, resistors, transformers, diodes, triodes, choke coils and capacitors. The direct current high-power energy-saving lamp controller is characterized in that the positive electrode of the power supply is connected with the positive electrode of the diode D1. The negative electrode of the diode D1 is connected with a resistor R1 and a resistor R2. The other end of the resistor R1 is connected with the base electrode of the triode V1. The other end of the resistor R2 is connected with the base electrode of the transistor V2. A secondary coil L3 of a transformer B2 is connected between the base electrode of the triode V1 and the base electrode of the triode V2. The elementary coils L1, L2 of the transformer B2 are connected in series and are connected between the collector of the triode V1 and the collector of the triode V2. A choke coil B1 is connected between the connecting points of the coils L1, L2 and the positive electrode of the power supply. A capacitor C1 is arranged between the collector of the triode V1 and the collector of the triode V2. The emitter of the triode V1 and the emitter of the triode V2 are connected with the earth. A secondary coil L4 and a capacitor C2 of the transformer B2 and the lamp are connected in parallel into a circuit. The utility model has the advantages of low circuit loss, low heating and high efficiency.
