220V's illumination voltage provides direct current power for control circuit through transformer coupling and bridge rectifier, three-terminal regulator steady voltage, filter capacitance filtering interchange, and RP2 constitutes the light control circuit with RG, and photosensitive resistor RG presents the low resistance by natural light illumination daytime, and when BISS0001 pin 9 level Vo is less than 02VDD, the trigger forbids, and back level circuits such as BISSO00l are out of work, and illumination lamps and lanterns H are not bright. At night or when the ambient light is dark, the resistance value of the RG is increased, when the level of the 9 th pin of the BISSOOI is played to be more than 0.2Vpp, the BISSOOI is in a monitoring state, and the output end is still at a low level. When the front degree of the illumination intensity received by the photoresistor RG is lower than a set threshold value, BISS0001 is allowed to be triggered, when no person enters the monitoring range of the pyroelectric sensor PIR, the pyroelectric infrared sensing signal processing integrated circuit BISS0001 is in a reset state, the control signal output end (No. 2 pin) Vo outputs a low level, the electronic switch VT9014 is in a cut-off state, the solid-state relay SSR is switched off, the lighting lamp H is not bright, and the controller is in a monitoring state. When a person enters a PIR monitoring range of the pyroelectric sensor and moves, the PIR can convert the change of infrared rays emitted by the human body into an electric signal to be output, and the frequency of the output signal is 0.1-10 Hz. If a person moves IN the PIR monitoring range, the PIR outputs an electric signal which changes along with the movement of the human body, or when a certain sound exists, the MIC converts the sound signal into the electric signal which is used as input together with the PIR electric signal through an OR gate, the electric signal is sent to an input end 11N + (14 th pin) of an independent high-input human impedance operational amplifier OP1 IN a BISS00O1 chip through RP1, the electric signal is output by a 16 th pin after being pre-amplified by OP1, the electric signal is coupled to a 13 th pin 2 IN-end through C4, the electric signal is amplified by a 2 nd-level operational amplifier OP 2IN the chip, the electric signal is processed by a two-way amplitude discriminator IN the chip, an effective trigger signal is output to start a delay timer TX IN the chip, and finally a high-level control signal is output from a 2 nd pin 001 of the BISSO 9014 by a state controller, so that the electronic switch VT 9014.

As the 1 st pin of the chip is connected with high level, the circuit is in a state of allowing repeated triggering, namely within the delay time (15 s), the circuit is triggered again as long as a person slightly moves or exceeds the set sound loudness, and the 2 nd pin outputs a high level signal with the pulse width of 15 s. The lighting fixture H will always be lit. After the person leaves and the time is delayed for 15s, the circuit is reset, and the lighting lamp H is automatically turned off, so that the purposes of intelligently adjusting the lighting circuit, saving energy and prolonging the service life of the lamp are achieved.
