It is convenient.
As shown in figure 4, the control circuit includes main loop of power circuit circuit 15, infrared acquisition sensor circuit 16 and infrared opens
Control circuit 17 is closed, the infrared acquisition sensor circuit 16 accesses light-sensitive element 161 and toggle switch S1, as described in Figure 1, described
The inductive switch 14 for controlling the toggle switch is equipped with outside top lampshade 2.
The electricity being serially connected that the main loop of power circuit circuit 15 includes chip IC 1, connect with the VCC of the chip IC 1
Hinder R3 and R4, with the DRAIN of the chip IC 1 inductance L3 connecting and diode D1, the inductance L3 and the diode D1
It is connected in parallel；It is described to be connect using resistance RS1 and RS2 with the CS foot of chip IC 1.The infrared acquisition sensor circuit 16 includes core
Piece IC2, the light-sensitive element 161 and toggle switch S1 are accessed in the OEN foot of the chip IC 2.The infrared switch control electricity
Road 17 includes sampling resistor RS1 and RS2 in parallel and the metal-oxide-semiconductor Q1 using resistance RS1 and RS2 series connection.
Main 15 course of work of loop of power circuit circuit is as follows: described resistance R3, R4 are depressured to chip IC 1 when energization
VCC power supply 8.5V, after the work of chip IC 1 within the Ton time that built-in MOS is opened, electric current is through the inductance component L 3, LED light
Pearl, sampling resistor RS1 and RS2 return to the GND of the chip IC 1, form access；Within the Toff time of its MOS shutdown, electric current
It is formed into a loop again through inductance L3, diode D1, LED lamp bead.In addition after this circuit connects the infrared acquisition sensor circuit 16,
Its work is also influenced by the infrared switch control circuit 17 and the infrared acquisition sensor circuit 16: due to the infrared spy
It surveys inside sensor circuit 16 and is set as opening electricity for the first time, the 3rd foot of chip IC 2 has the high level (i.e. pwm signal) of output 3V, defeated
It is sent to the grid of the metal-oxide-semiconductor Q1 in ON-OFF control circuit, the grid of metal-oxide-semiconductor Q1 is high level, and its drain electrode is also high level, full
Its ON operation of foot, such electric current are formed into a loop from its source electrode to ground (GND), and the main loop of power circuit circuit 15 described in this way can be with work
Make, i.e., lamp is lit, and after a period of time, the 3rd foot output of sensor circuit becomes low level, and the grid of such metal-oxide-semiconductor Q1 obtains not
It cannot be connected to enough voltage, the main loop of power circuit circuit 15 cannot be formed into a loop and cannot work, and lamp goes out, and just start later
Outer red signal is detected, realizes inducing function.
16 course of work of infrared acquisition sensor circuit is as follows: being radiated around centered on Fresnel Lenses 1, works as shifting
The infrared signal (wavelength 8-12um) that dynamic human body radiation goes out is by Fresnel Lenses 1, then is refracted to the detection member of detector 18
On, filtering of the signal through 18 internal circuit of detector the processing such as amplifies, compares and is converted into electric signal, this electric signal transmission to institute
It states inside the chip IC 2 of infrared acquisition sensor circuit 16, then is compared by the signal processing inside chip IC 2, as long as connecting in 4S
The continuous internal threshold for having 2 signals to be greater than REL foot, REL foot will export a pwm signal, the conveying of this pwm signal later
To at the metal-oxide-semiconductor Q1 grid of infrared switch control circuit 17, metal-oxide-semiconductor Q1 is connected, the electric current for flowing through LED lamp bead in this way can be from
The drain-to-source of metal-oxide-semiconductor Q1, which flows through, returns again to GND, and forming circuit, LED light is lit, and the time lighted is maintained voluntarily
The time of setting.Detector 18 is always in constantly detection infrared signal within the time that lamp is lighted, as long as continuously monitoring letter
Number, then ONT foot timer also resets therewith, namely holding time of lighting is opened subject to infrared signal from detecting for the last time
Beginning recalculates the time.
The power supply circuit of the infrared acquisition sensor circuit 16 is as follows: voltage is depressured by resistance R1 and R2, by pressure stabilizing two
Pole pipe DZ clamper is transported to U1 element in 10V, through electrolytic capacitor C6 filtering, is transported to core through the voltage that U1 pressure stabilizing output is 3.3V
The VDD foot of piece IC2 provides the operating voltage of the chip IC 2 of the infrared acquisition sensor circuit 16.This circuit does not use independence
Integrated circuit, it is relatively simple, it is at low cost.
In addition, the OEN foot of chip IC2 element has accessed 161 He of light-sensitive element in the infrared acquisition sensor circuit 16
Toggle switch S1 introduces the factor of light in the infrared acquisition sensor circuit 16, that is, a day mode has been manually set
And night mode: when toggle switch S1 is closed, light-sensitive element 161 accesses OEN foot, as long as light luminance reaches one in external environment
Determine degree, then the resistance value of light-sensitive element 161 is sufficiently low, makes the voltage of OEN foot lower than 2V, the inside Schmidt of chip IC 2 touches
Sending out device output is low level, forbids REL foot, the grid no-voltage of such metal-oxide-semiconductor Q1 is not turned on, and lamp does not work.Namely in OEN foot
When voltage is lower than 2V, no matter the infrared acquisition sensor circuit 16 is either with or without mobile infrared signal is detected, lamp all will not point
It is bright.It is applied under such state at night, referred to as night mode more；When toggle switch S1 is disconnected, light-sensitive element 161 does not access electricity
Lu Zhong, OEN foot is hanging at this time, and voltage is fixed as 3V, and REL is effective, as long as detecting continuous infrared signal, sensor circuit work
To make, REL foot exports high level and metal-oxide-semiconductor Q1 is connected, and circuit is formed, and lamp is bright, under such state, no matter ambient brightness,
As long as there is mobile infrared signal, lamp, which can incude, to be lighted, and is referred to as day mode.Such design can be used in user is met
Different environmental demands.
Lamp body installation process is as follows:
(1) the male end contact pin of 4 side light source board components 7 is first passed through to the female end of lamp body lower cover 8 and connector connecting plate 9
Connector is attached；
(2) side light source assembly 7 is inserted into side lampshade 6 again, then uses screw 10 by lamp body lower cover 8 and side light
