As shown in fig. 1 and 3, in the evening time period, when the photoelectric switch, the trigger circuit and the wireless transmitting module U4 are powered to work, if the user needs to get out of the bed to enter the toilet, since the element case 9 is located at the side end of the bed and at the side of the walk-through of the bedroom, therefore, the user getting up will temporarily block the infrared light emitted from the emitting head of the photoelectric switch U1, thus, under the action of the internal circuit of the photoelectric switch U1, the 3 pin outputs high level, the high level is reduced by the resistor R1, the current is limited, and then the current enters the other end of the resistor R1, and enters the pin 3 of the double-D trigger integrated circuit U3 through the resistor R1, so that the double-D trigger integrated circuit U3 generates one-time overturn of the bistable trigger circuit formed by the double-D trigger integrated circuit U3 under the action of the internal circuit thereof, a pin 1 of the relay can always output high level, the high level is subjected to voltage reduction and current limitation through a resistor R2 and enters the base electrode of an NPN triode Q1, and an NPN triode Q1 is conducted, the collector electrode of the NPN triode Q1 outputs low level and enters the negative power supply input end of a relay K1; because the positive power supply input end and the control power supply input end of the relay K1 are connected with the 3 pins of the stabilized voltage power supply U, the relay K1 can be electrically pulled to close the control power supply input end and the normally open contact end (the control power supply input end and the normally closed contact end are open circuit); because the normally open contact end of the relay K1 is connected with the positive power input end of the first control circuit (the negative power input end of the first control circuit is connected with the 4-pin negative power output end of the stabilized voltage power supply U), the first control circuit can be powered to work at the moment. After the first control circuit works by electrifying, the positive pole of a 12V power supply output by a stabilized voltage power supply U can be subjected to voltage reduction and current limitation through a resistor R4 to charge an electrolytic capacitor C1, when the electrolytic capacitor C1 is not fully charged in the beginning time period, the base voltage of an NPN triode Q2 is lower than 0.7V and is in a cut-off state, at the moment, the base of the NPN triode Q3 can obtain proper forward bias current (higher than 0.7V) from the positive pole of the 12V power supply by virtue of voltage reduction and current limitation through resistors R5 and R6 to be conducted, so that the collector of the NPN triode Q3 outputs low level to enter the negative power supply input end of a relay K2 (the positive power supply input end of the relay K2 is communicated with the positive pole of the 12V power supply), and the relay K2 is electrified to; at the moment, the wireless transmitting circuit module U4 is in an electrified working state, and the control contact end and the normally open contact end of the relay K2 are respectively connected with the two contacts below the first wireless signal transmitting key S1 key of the wireless transmitting circuit module U4, so that the two contacts below the first wireless signal transmitting key S1 key of the wireless transmitting circuit module U4 are communicated, and a first path of wireless closing signal is transmitted; when the charging is carried out for about 3 seconds, the electrolytic capacitor C1 is fully charged, at the moment, the base electrode of the NPN triode Q2 is subjected to voltage reduction and current limitation through the resistors R3 and R4, the power supply voltage obtained from the 12V power supply anode is higher than 0.7V, then the NPN triode Q2 conducts the collector electrode thereof to output low level, the low level enters the base electrode of the NPN triode Q3 through the resistor R6, thus, the base electrode of the NPN triode Q3 is in a cut-off state due to no proper forward bias current, the collector electrode thereof stops outputting low level, further, the relay K2 is no longer electrified to attract the control contact end and the normally open contact end thereof to be open, and the wireless transmitting circuit module U4 stops transmitting wireless signals; through the above, when the user gets up at night, the wireless transmitting circuit module U4 will transmit the first wireless close signal, and stop transmitting the wireless close signal after 3 seconds (prevent the wireless transmitting circuit module U4 from transmitting the wireless signal continuously for a long time and causing damage). In practical use, when a user gets off the bed and walks towards a toilet or the like without blocking the infrared light emitted by the detection head of the photoelectric switch U1, although the 3 pin of the photoelectric switch U1 stops outputting the high level, the 1 pin of the dual D flip-flop integrated circuit U3 always keeps outputting the high level, and therefore the first control circuit is always in the working state.

As shown in fig. 3 and 4, when the wireless receiving circuit is powered on to work, after a user gets up to block infrared light emitted by the emitting head of the photoelectric switch U1 at night and the wireless emitting circuit module U4 emits a first path of wireless closing signal, the wireless receiving circuit module U6 of the wireless receiving circuit located in a bedroom and a bathroom receives the wireless closing signal, so that the 4 th pin outputs a high level, the high level is reduced in voltage and limited in current through the resistor R12 to enter the base of the NPN triode Q8, the NPN triode Q8 conducts the collector thereof to output a low level to enter the negative power input end of the relay K5 (the positive power input end of the relay K5 is communicated with the 3 pins of the switching power supply U5), then the relay K5 is powered on to attract the control power input end and the normally open contact end of the relay K5 to be connected with one pole of the 220V ac power supply, the normally open contact end of the relay K5, The other pole of the 220V alternating current power supply is respectively connected with the input ends of the power supplies of the illuminating lamps H in the bedroom and the bathroom, so that the illuminating lamps H in the bedroom and the bathroom can emit light by electricity; the illuminating lamp provides illumination for the user after getting out of bed and after reaching a student, and reduces the probability of falling and foreign matter collision caused by no illumination before getting out of bed and turning on the lamp.
