With reference to Fig. 1, a kind of SCM Based LED illuminator that the utility model provided mainly comprises singlechip controller 1; At least four pyroelectric sensors 2 are connected with singlechip controller respectively; Light sensor 3 is connected with singlechip controller 1; Lighting unit 4 is made up of the led module 42 of constant-current driven module 41 that is connected with singlechip controller 1 and connection constant-current driven module 41; At least 4 LED lighting units 6 are connected with singlechip controller 1; Steering wheel 5 is connected with singlechip controller 1, and it has the steering head 51 that receives singlechip controller control, and this steering head has two degrees of freedom at least.
The singlechip controller 1 of the utility model can select for use the STC89C52RC single-chip microcomputer of paster as the master control chip, the volume of the drive circuit of saving greatly; And be the power supply of chip and the power supply of other elements, can adopt 220V to change the 9V transformer, make through devices such as voltage stabilizing chip LM7805 and some filter capacitors again.
For reaching enough irradiation brightness, led module 42 can adopt mode parallel with one another, is made up of many 1W high-brightness white-light LED lamp pearls altogether; The about 3.1V of pressure drop of every LED lamp pearl, the about 200mA of operating current.Forward voltage-current characteristic by white light LEDs can be known; After the LED terminal voltage surpasses its forward conduction voltage, less voltage fluctuation all can cause operating current acute variation, thereby influence the normal use of LED; So LED should adopt constant current drive mode, promptly adopts constant-current driving mould 41 to realize; As shown in Figure 2, constant-current driving mould 41 mainly reaches the pwm circuit 412 that is connected with ballast filter circuit 411 by ballast filter circuit 411 and forms; The pwm circuit 412 preferred high-performance BP1360 constant current chip drives that adopt in the utility model, BP1360 is the step-down constant-current source chip of a continuous current conduction mode, can direct voltage be directly changed into stable constant current output; It adopts the input of the wide voltage of 6 ~ 30V, and output current can reach 1.2A, and conversion efficiency is up to 97%, and the output current precision reaches ± and 5%.This chip internal contains trembles characteristic frequently, improves EMI greatly, has multiple functions such as excess temperature, overvoltage, overcurrent, LED open-circuit-protection simultaneously.This chip is suitable for green illumination LED lamp drive circuit, has the very succinct advantage of application circuit.
The utility model can be applicable to various indoor and outdoor occasions, and when work, light sensor 3 and pyroelectric sensor 2 are realized the brightness of surrounding environment and the detection of personnel's situation, thereby realized automatic illumination adjustment.Wherein, can simulate easily or the PWM light modulation through the end of the DIM on the BP1360 chip.Because the simulation light modulation is directly to change the size that flows through the LED electric current to realize brightness regulation, except the brightness meeting changes, also can influence the quality of white light, promptly different electric flows down the white light that sends and has colour cast.Therefore, the utility model adopts PWM light modulation scheme, and the basic principle of PWM light modulation is to keep LED forward conduction current constant, and passes through the time scale of Control current conducting and shutoff, promptly changes the duty ratio of input pulse signal, makes LED produce bright dark variation; And utilize the persistence of vision effect of human eye, when LED switch change frequency during greater than 120Hz, human eye just can not felt flicker, and sees it being the mean flow rate of LED.The advantage of PWM light modulation is that the electric current of LED forward conduction is constant, and the colourity of LED does not change in the time of just can not looking like to simulate light modulation.
As shown in Figure 3, the PWM pulse signal is then produced by single-chip microcomputer pin P2.7, the on off operating mode of its high-low level decision LED.Predicate 200 μ S during timer T0 overflowed, per 10 subpulses are as one-period, and promptly frequency is 5000HZ.Like this, in per 1/5000 second square-wave cycle, through the output duty cycle of change square wave, thus 10 grades of brightness regulation of realization LED lamp, promptly the LED brightness degree is determined by the high level pulse number in each cycle.When the high level pulse number was 1, duty ratio was 1/10, and brightness is minimum, its light modulation principle as shown in; When high level pulse was 10, duty ratio was 1, and LED brightness is the highest.

Because human body all has constant body temperature, generally about 37 ° of C, can send the infrared ray of 10mm left and right sides specific wavelength, pyroelectric sensor 2 leans on the infrared ray that the detection human body launches and carries out work.Infrared ray gathers the pyroelectricity element after strengthening through the Fresnel filter, and this element will lose charge balance when receiving the human infrared radiation variation, outwards discharge electric charge, just can produce alarm signal after detect the processing back.Ambient background radiation is released element to two heat and is almost had identical effect, makes its generation release electrical effect and cancels out each other, so the output of detector no signal.Among the design, pyroelectric sensor 2 adopts HC-SR501 plain edition human body infrared induction module pyroelectric infrared sensors, gets into then input high level of its induction range as the people, the people leave induction range then automatic time delay close high level, output low level.
Simultaneously, in order to accomplish that lighting unit 4 can open when the dim light; When light is strong, extinguish.Therefore light sensor 3 designs correspondent peripheral circuit, and as shown in Figure 4, P5 connects light sensor 3, and the not conducting of triode of sufficient intensity light time is arranged, and relay is opened, and P6 connects D5 high-brightness LED power supply, and the LED power supply breaks off, so led module 42 does not work.When dark, the triode conducting, relay closes, led module 42 is bright.Simultaneously in scm software, the method that adopts time-delay to repeat to judge in 5 seconds is confirmed the variation of light, closes the LED shot-light to escape the mistake that lightning in night or automobile lamp cause.
Consider that outdoor pyroelectric sensor 2 usually has a lot of inconvenience in installation wiring, therefore can consider wireless transmission scheme as shown in Figure 5, be about to pyroelectric sensor 2 and be connected with singlechip controller 1 through wireless transport module 7.Wireless transport module 7 preferably can be selected the transceiver module that PT2262 and PT2272 form for use in the utility model; Set up the network of a wireless sensing; Transmit in the convenient space of switching value signal of realizing; During work, the steering head 51 through steering wheel 5 lets lighting unit 4 forward corresponding position to, and steering wheel 5 is accepted to rotate from the control signal control steering head 51 of singlechip controller 1.The output shaft of steering wheel 5 links to each other with the position feedback potentiometer; When steering head 51 rotates, drive the position feedback potentiometer, potentiometer will be exported a voltage signal to control circuit board; Feed back; Control circuit board then, rotation direction and speed according to position decision steering head 51 stop thereby reaching target.The control signal of steering wheel 5 is to be pulse-width modulation (PWM) signal of 20ms in the cycle, and wherein pulse duration is from 0.5ms-2.5ms, and the position of corresponding steering wheel is the 0-180 degree, is linear change.
As shown in Figure 6, in preferred embodiments, the design is divided into 4 zones with the field of illumination, 5 illumination orientations.Illumination position and illumination power have strict control, and the position that steering wheel 5 turns to is at every turn all fixed, and can not produce skew because of forwarding other position to by diverse location.The brightness of illumination unit 4 simultaneously also has fixing adjusting; At first use light sensor 3 testing environment brightness, when ambient brightness was dark, signal of light sensor 3 inputs was to singlechip controller 1; Fly P2.0 mouth human body pyroelectric sensor 2 detected signals with singlechip controller 1 then; When the people came, P2.0 received high level, and P2.0 receives low level when the no one comes.It is bright that someone then controls lighting unit 4, and during the no one, 4 the LED lighting units 6 in control next door extinguish one by one, and middle lighting unit 40 contrast light reduce brightness one by one to 20% of original luminance.When irradiation had only people from zone that arranged under the environment, the brightness that lighting unit 4 sends was when in 25%, two zone the people being arranged, and the brightness of lighting unit 4 is that the luminous brightness of LED is 100% when in 75%, three and four zones people being arranged.
Shown in figure, on four positions, pyroelectric sensor 2 is housed, when having detected the people; Pyroelectric sensor 2 inputs to the wireless transmitter module in the wireless transport module 7 with signal; Lean on wireless transmitter module emission wireless signal then, be delivered to the wireless reception module, because four wireless receiving modules have four different addresses; Therefore can distinguish the corresponding position of wireless transmitter module; Can confusion reigned, by wireless receiving module signal is inputed to singlechip controller 1 at last and confirm the position, order steering wheel 5 forwards corresponding position to.
Certainly; The utility model is created and is not limited to above-mentioned execution mode; Those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite of the utility model spirit, modification that these are equal to or replacement all are included in the application's claim institute restricted portion.
