As shown in fig. 1 and 2, the novel lamp holder is used based on the existing indoor lamp holder, the user can connect the novel lamp holder body 1(DT) into the indoor original lamp holder through simple operation, and can connect the lamp holder of the bulb 8(H) into the internal thread of the novel lamp holder body 2(DZ), so that the novel lamp holder and the bulb 8(H) can be connected without installation of a professional, thereby saving the installation cost and bringing convenience to the user. At ordinary times, a user turns on a power switch matched with a bulb 8(H), a 220V alternating current power supply enters two terminals of a lamp holder body DZ through two terminals of a lamp holder body DT, the bulb H is electrified to emit light, the 220V alternating current power supply enters one end of a step-down capacitor C and one end of a resistor R1, the 220V alternating current power supply is subjected to step-down through the step-down capacitor C and the resistor R1, the power supply is added on two voltage stabilizing diodes VZ1 and VZ2 which are reversely connected in series, when the power supply is in a positive half cycle, 14V pulsating direct current voltage is obtained at the negative pole of the voltage stabilizing diode VZ1, and the voltage is respectively subjected to unidirectional conduction rectification through diodes VD1 and VD2 to charge electrolytic capacitors C1 and C2; when the power supply is in a negative half cycle, 14V pulsating direct current voltage is obtained at the negative pole of the voltage stabilizing diode VZ2, the voltage is rectified to charge the electrolytic capacitors C1 and C2 through the unidirectional conduction of the diodes VD3 and VD4, and therefore, about 14V direct current power supplies can be obtained at the positive poles and the negative poles of the electrolytic capacitors C1 and C2. After a 14V direct-current power supply enters 1 pin and 2 pins of a three-terminal fixed output integrated voltage stabilizer A1 (simultaneously enters one end of a resistor R2), a three-terminal fixed output integrated voltage stabilizer A1 outputs a stable 12.7V direct-current power supply by 3 pins under the action of ceramic chip capacitors C3 and C4 and a diode VD5 (the ceramic chip capacitors C3 and C4 play a role in filtering, the output voltage of the 3 pins of the three-terminal fixed output integrated voltage stabilizer A1 is 12V, after a diode is connected in series between the 2 pins at the negative power supply input end of a negative power supply and a negative power supply of a conversion circuit, the output voltage of the 3 pins of the three-terminal fixed output integrated voltage stabilizer A1 enters the power supply input end of a storage battery G under the action of an internal circuit of the three-terminal fixed output integrated voltage stabilizer A1, the storage battery G is charged in a floating mode; the power supply output by the positive electrode of the storage battery G enters the other end of the resistor R3, the emitting electrode of the PNP triode Q5 and the control and positive electrode power supply input end of the relay J.

As shown in fig. 2, at ordinary times, after the user turns on the indoor power switch (connected to the original indoor lamp holder via the wire), under the action of the switching circuit, the positive electrode of the 14V power supply is subjected to voltage reduction and current limitation (higher than 0.7V) via the resistor R2 and then enters the base of the NPN triode Q1, so that the NPN triode Q1 is in a conducting state, the collector of the NPN triode Q1 outputs a low level and enters the base of the NPN triode Q2, the base of the NPN triode Q2 has no proper forward bias current and is in a cut-off state, the subsequent PNP triode Q5 is not conducted and is in a cut-off state, the subsequent electrolytic capacitor C5 is not charged, the NPN triode Q4 is in a cut-. In practical application, after a user turns off an indoor power switch, as a 220V alternating current power supply does not enter the other end of the resistor R1 or the other end of the capacitor C, a 14V power supply is not generated at the positive and negative poles of the electrolytic capacitor C1 and C2, so that the base of the NPN triode Q1 is cut off due to no forward bias current and does not output a low level to enter the base of the NPN triode Q2, further, the base of the NPN triode Q2 obtains a proper forward bias current from the positive pole of the storage battery G through the voltage reduction and current limitation of the resistor R3, the collector thereof outputs a low level to enter the base of the PNP triode Q5, and the PNP triode Q5 is turned on and outputs a high level to one end of the resistors R4 and R5. After the positive pole of the 12V power supply enters one end of a resistor R4, the positive pole of the 12V direct current power supply is subjected to voltage reduction and current limitation through a resistor R4 to charge an electrolytic capacitor C5, and when the electrolytic capacitor C5 is not fully charged within 6 seconds from the beginning, the base voltage of the positive pole of the 12V power supply entering an NPN triode Q3 after the positive pole of the 12V power supply is subjected to voltage reduction and current limitation through a resistor R4 and a resistor R6 is lower than 0.7V, and the NPN triode Q3 is in a cut-off state and has no collector output, so that the base of the NPN triode Q4 obtains proper forward bias current conduction (higher than 0.7V) from the 12V positive power supply through the resistor R5, the collector outputs high level to enter the positive power supply input end of a relay J, and the relay J is electrified to; because the relay J controls the power supply input end to be connected with the positive pole of the storage battery G, the normally open contact end is connected with the pin 1 of the DC-AC power supply module A2 and the positive power supply input end of the relay J1 (the pin 2 of the DC-AC power supply module A2 is communicated with the negative pole of the storage battery G), at the moment, the DC-AC power supply module A2 is in a power-on working state (meanwhile, the relay J1 is powered on to attract the control power supply input end and the normally closed contact end to be open circuit); after the DC-AC power supply module A2 is powered on to work, under the action of an internal circuit thereof,

pins

3 and 4 can output an alternating current 220V power supply to enter two terminals of the lamp holder body (equivalent to two terminals of the power supply of the lamp bulb H), and then the lamp bulb H can continue to be powered on to emit light after a user turns off a power switch (because the control power supply input end and the normally closed contact end of the relay J1 are connected in series between the other end of the step-down capacitor C of the conversion circuit and one of the terminals of the lamp holder body DT, at the moment, because the relay J1 is powered on to attract and the control power supply input end and the normally closed contact end are open, the other end of the step-down capacitor C cannot be powered on, and the influence of the power generated at the positive and negative electrodes of the electrolytic capacitors C. When the bulb H is powered on, the 12V DC power supply (because the PNP triode Q5 drops the actual voltage by about 11.7V) continues to be current-limited to charge the electrolytic capacitor C5 through the resistor R4, after charging for 6 seconds, when the electrolytic capacitor C5 is fully charged, the positive electrode of the 12V power supply is current-limited through the resistor R4 and the resistor R6, and then enters the base voltage of the NPN triode Q3 which is higher than 0.7V, the NPN triode Q3 is in the on state, and the collector thereof outputs a low level to the base of the NPN triode Q4, so the base of the NPN triode Q4 is in the off state due to no suitable forward bias current, and the collector thereof no longer outputs a low level to the negative power supply input terminal of the relay J, then the relay J and the J1 are successively powered off and no longer attract, and further, the DC-AC power supply module a2 no longer works when the bulb H is powered off, and; because the relay J1 loses power and controls the power supply input end and the normally closed contact end to be closed again, one end of the voltage reduction capacitor C is communicated with one of the terminals of the lamp holder body DT, and preparation is made for a user to turn on the power supply switch next time and to normally light the lamp bulb H before the power supply switch is not turned off. Through the combined action of the circuits, a user turns on the power switch every time, the bulb H is powered on, and after the power switch is turned off, the bulb H can automatically delay to be powered on and emit light for 6 seconds, so that the user can go out of a dark indoor area after turning off the lamp. After the user turns on the lamp next time, because the NPN triode Q1 is turned on again, and the NPN triode Q2 and the PNP triode Q5 are turned off again, then the collector of the PNP triode Q5 does not charge the electrolytic capacitor C5 any more, the electrolytic capacitor C5 finishes releasing the charged voltage quickly, and the user turns off the lamp after turning on the lamp, and the charging delay control lamp H is continuously powered on for 6 seconds to prepare.
