Zusammenfassung:	The utility model relates to the technical field of alternating current. The utility model provides a semi-automatic door lamp circuit. The circuit comprises a power supply connector, a photoresistorRG, resistors R1, R2 and R3, an adjustable resistor RP, a capacitor C, micro-triggering silicon controlled rectifiers SCR1 and SCR2, a neon lamp Ne, a metal sheet M and a bulb, the positive electrodeof the power connector is connected with one end of a resistor R1 and the A end of a micro-trigger silicon controlled rectifier SCR1 through a lamp. Wherein the K end of the micro-triggering silicon controlled rectifier SCR1 is connected with the negative electrode of the power connector and one end of the capacitor C, the other end of the resistor R1 is connected with the A end of the micro-triggering silicon controlled rectifier SCR2, and the K end of the micro-triggering silicon controlled rectifier SCR2 is connected with one end of the resistor R2, the other end of the capacitor C and oneend of the adjustable resis
