As shown in fig. 2, after the 220V ac power enters the two

terminals

1 and 2 of the power input of the regulated power supply U1, the

pins

3 and 4 of the regulated power supply U1, under the action of its internal circuit, will output a stable 9V dc power to enter the two terminals of the power input of the light control circuit, the infrared detection circuit, and the dimming circuit, so that the light control circuit, the infrared detection circuit, and the dimming circuit are in a power-on operating state. In the light control circuit: when the light of the corridor environment is strong at ordinary times, the light receiving surface of the photoresistor RL has high illumination intensity and small resistance value (about 100K), so that the positive electrode of a 9V direct-current power supply is subjected to voltage reduction and current limitation by the photoresistor RL and enters the base electrode of an NPN triode Q1, the voltage is higher than 0.7V, the NPN triode Q2 is conducted, the collector electrode of the NPN triode Q2 outputs low level and enters the base electrode of an NPN triode Q2, the base electrode of the NPN triode Q2 is in a cut-off state without proper forward bias, 2 feet of a pyroelectric infrared detection module U2 of a subsequent infrared detection circuit cannot input low level and are in a power-off state; when light of the corridor environment is weak at ordinary times, the light receiving surface of the photoresistor RL is low in illumination intensity, the resistance value of the photoresistor RL is very large (about 10M), therefore, the positive electrode of a 9V direct-current power supply is subjected to voltage reduction and current limitation through the photoresistor RL, the voltage is lower than 0.7V after the positive electrode enters the base electrode of the NPN triode Q1, the NPN triode Q1 is cut off, the collector electrode of the NPN triode Q2 does not output any level to enter the base electrode of the NPN triode Q2, then, the base electrode of the NPN triode Q2 is subjected to voltage reduction and current limitation through the resistor R1, proper forward bias conduction (higher than 0.7V) is obtained from the 9V power supply, the collector electrode of the NPN triode Q2 is conducted to output a low level to; through the above, when the corridor light environment is good, the pyroelectric infrared detection module U2 can not work by electricity, the subsequent corridor lamp HL can not light by electricity, and when the corridor light environment is not good, the pyroelectric infrared detection module U2 works by electricity, and conditions are created for the subsequent corridor lamp HL to light by electricity.

As shown in fig. 2, after the pyroelectric infrared detection module U2 is powered on to operate, under the action of its internal circuit, when no one goes up and down between the upper and lower stairs of the corridor, the detection head of the pyroelectric infrared detection module U2 at the middle part of the front end of the wall surface at the corner between the upper and lower stairs of the corridor will not output high level because no infrared signal generated by a moving human body is detected, and the subsequent corridor lamp HL will not be powered on to emit light; in practical application, when a person goes up and down between an upper stair layer and a lower stair layer of a corridor, and an infrared signal generated by a movable human body is detected (the farthest detection distance can reach 15 meters under the action of a Fresnel lens) by a detection head of a pyroelectric infrared detection module U2 at the middle part of the front end of a wall surface at a corner between the upper stair layer and the lower stair layer of the corridor, a pin 1 of the pyroelectric infrared detection module U can output a high level and enter one end of a resistor R2 through a switch diode VD in a one-way conduction mode, then the high level enters a base electrode of an NPN triode Q3 through a resistor R2 in a voltage reduction and current limiting mode, an NPN triode Q3 conducts a collector electrode of the NPN triode Q3 to output a low level and enters a negative electrode power supply input end of a relay K1 (an; because the control power input end of the relay K1 is connected with the 220V alternating current power phase line L, and the normally open contact end of the relay K1 is connected with one power input end of the corridor lamp HL, one power input end of the corridor lamp HL can be electrified at the moment, and conditions are created for the luminescence of the corridor lamp HL.

As shown in fig. 2, after the dimming circuit is powered on to operate (the other end of the zero line N and the ceramic chip capacitor C1 of the 220V ac power supply, the other end of the resistor R3, the first main electrode T1 of the triac VS, the emitter of the NPN triode Q5, the other end of the resistor R5, and the other end of the adjustable resistor RP3 are normally on), the corridor lamp HL can be powered on to emit light; in the dimming circuit, a light measuring circuit is composed of an adjustable resistor RP3, a photosensitive resistor RL1 and a PNP triode Q6, and a complementary self-coupling amplifier is composed of an NPN triode Q5, a PNP triode Q4, a Q6, peripheral element resistors R5 and R4 and an adjustable resistor RP 1; in practical situations, when the light of the corridor is not strong, the resistance value of the photosensitive resistor RL1 will be increased, the low-level (higher than 0.7V starting voltage of the base of the PNP triode Q6) current input through the adjustable resistor RP3 at the base of the PNP triode Q6 will be increased and then conducted, so the collector current of the PNP triode Q6 will also be increased, the current output by the collector of the PNP triode Q6 (the high level is output by the collector of the PNP triode Q6) will be amplified by the NPN triode Q5 (the low level is output by the collector of the NPN triode Q5) and the PNP triode Q4, and the high level is output from the collector of the PNP triode Q4 to charge the ceramic chip capacitor C1; when the ceramic chip capacitor C1 is charged for a certain value, the voltage of the emitter of the double-base triode VU is increased and conducted, pulses are generated at the first base of the double-base triode VU and one end of the resistor R3, the bidirectional thyristor VS is triggered and conducted, and the 220V power zero line enters the other power input end of the corridor lamp HL (at the moment, one power input end of the corridor lamp HL controls the communication of the power input end, the normally open contact end and the 220V alternating current power phase line L through the relay K1), so that the corridor lamp HL can be electrically lighted; in practical situations, the darker the ambient light around the corridor, the larger the resistance value of the photoresistor RL1, the larger the current entering the base of the PNP triode Q6, the larger the current amplified by the PNP triodes Q6 and Q4 and the NPN triode Q5, so that the faster the charging speed of the collector of the PNP triode Q4 to the ceramic chip capacitor C1, the more forward the pulse triggering the triac VS control electrode, the higher the voltage at the two ends of the corridor lamp HL, and the higher the luminous intensity; when the ambient light around the corridor is bright, the smaller the resistance value of the photoresistor RL1 is, the smaller the low-level current input by the adjustable resistor RP3 at the base of the PNP triode Q6 is, then, the smaller the current amplified by the PNP triodes Q6 and Q4 and the NPN triode Q5 is, so that the slower the charging speed of the collector of the PNP triode Q4 to the ceramic chip capacitor C1 is, the more backward the pulse triggering the control electrode of the bidirectional thyristor VS is, the lower the voltage at the two ends of the corridor lamp HL is, and the lower the luminous intensity is, thereby meeting the proper luminous intensity of the corridor lamp HL, and achieving the purpose of saving electricity while achieving the proper luminous intensity of the corridor. In practical situations, a manufacturer can set different voltage division values of the adjustable resistor RP3 and the photosensitive resistor RL1 by adjusting the resistance value of the adjustable resistor RP3, so that the illuminating lamp HL can be electrified and emit light in different illumination environments in a corridor; the smaller the resistance value of the adjustable resistor RP3 is adjusted, the smaller the voltage division is, because the current entering the base electrode of the PNP triode Q6 through one end of the adjustable resistor RP3 is relatively low (lower than 0.7V), under the premise of high illumination and small resistance value of the photoresistor RL1, the divided voltage can be increased to the point that the voltage at the base electrode of the PNP triode Q6 is lower than the initial voltage, the PNP triode Q6 is in a cut-off state, the follow-up PNP triode Q4 and NPN triode Q6 are also cut off without output, the double-base triode VU is cut off, the bidirectional thyristor VS controls the electrode to lose trigger pulse, and then the corridor lamp HL loses power and stops emitting light; that is to say, after the resistance value of the adjustable resistor RP3 is adjusted to be small, the corridor lamp HL loses power and stops lighting in a relatively high-illumination environment in the corridor subsequently. The larger the resistance value of the adjustable resistor RP3 is adjusted, the larger the voltage division is, the higher the current entering the base electrode of the PNP triode Q6 through one end of the adjustable resistor RP3 is, the higher the resistance value is, the higher the photoresistor RL1 can increase the divided voltage until the voltage at the base electrode of the PNP triode Q6 is lower than the initial voltage thereof, the PNP triode Q6 is in a cut-off state, the follow-up PNP triode Q4 and NPN triode Q5 are also cut off without output, the double-base triode VU is cut off, the bidirectional thyristor VS controls the electrode to lose trigger pulse, and further the corridor lamp HL loses power and stops emitting light; that is to say, after the resistance value of the adjustable resistor RP3 is adjusted to be large, the corridor lamp HL will lose power and stop lighting in the relatively low light environment in the corridor. During specific adjustment, in production, a debugging worker places the novel adjustable resistor RP3 in an environment with minimum illumination requirements, namely the corridor HL cannot be powered to emit light above the illumination intensity environment, the resistance value of the adjustable resistor RP3 is slowly adjusted during adjustment, and when the corridor lamp HL is powered off and cannot emit light any more, the resistance value of the adjustable resistor RP3 is adjusted to a required resistance value; in the subsequent application, when the corridor light is higher than the minimum illumination required intensity, the corridor lamp HL loses power, and when the corridor light is lower than the minimum illumination required intensity, the corridor lamp HL can be powered to emit light; after the adjustment is completed, the adjustable resistor RP3 and the circuit can be disconnected, the resistance value of the adjustable resistor RP3 is measured by using a resistance gear of a multimeter, the measured resistance value is the resistance value of the adjustable resistor RP3 required by production (in actual production, the resistance value of the adjustable resistor RP3 is determined only once, the resistance value of the adjustable resistor RP3 is directly adjusted in place in advance in subsequent production or is directly replaced by a fixed resistor with the same resistance value), and the adjustable resistor RP3 is connected into the circuit after the resistance value of the adjustable resistor RP3 is determined.

In fig. 2, it is shown that, in this novel application, adopt infrared detection circuit as the technical scheme who detects whether someone gets into the corridor, under the light-operated circuit effect, when ambient light is good, follow-up corridor lamp HL can not get electric light-emitting, when ambient light is not good, follow-up someone passes through, and the corridor lamp just can get electric light-emitting, has reached automatic control and energy-conserving purpose. When a person goes up and down the corridor and between the upper and lower stairs, the finished product of the pyroelectric infrared detection module at the middle part of the front end of the wall surface at the corner between the upper and lower stairs can effectively detect the information of the movement of the human body, and the corridor lamp is controlled by the dimming circuit to obtain the electric luminous intensity, after the person goes out of the detection range, the corridor lamp HL is de-energized and does not emit light any more, and under the premise of automatic control, the requirement of the illumination time when the person with slow walking speed passes through the corridor can be effectively met. This neotype infrared detection circuit detection personnel can overcome the not effective energy-conservation that can not brought of prior art sound detection mode through the mode of corridor to can give the drawback that the slow people of walking speed brought inconvenience. During operation, the dimming circuit can effectively automatically adjust the illumination intensity of the corridor lamp HL according to the surrounding environment, and the energy-saving purpose can be achieved on the premise of meeting the illumination intensity requirement.
