Preferably, described first switching tube Q1 and second switch pipe Q2 is the field effect transistor of N raceway groove or the triode of NPN, and described 3rd switching tube is the field effect transistor of P raceway groove or the triode of PNP.
As a kind of specific embodiment, please refer to shown in Fig. 3, described switch switching unit is SP3T slide switch, and described SP3T slide switch has three gears, is respectively the first gear SENSOR, the second gear STRONG, third gear WEAK; Described first switching tube Q1 is the MOSFET of N raceway groove, and second switch pipe Q2 is the triode of NPN, and the 3rd switching tube Q3 is the triode of PNP; First link of described switching circuit unit, the second link and the 3rd link are a three-pin connector, during use, directly correspondingly with the positive pole of fluorescent tube, the feedback resistance of drive circuit and negative pole to connect.Be described in detail below with reference to the operation principle of this specific embodiment to human motion induction light adjusting and controlling device provided by the invention and introduce.
When SP3T switching over is to SENSOR shelves, this is that light adjusting and controlling device of the present invention responds to gear normally, and signal processing module normally works.After described signal processing module receives the voltage signal of the change that signal acquisition module exports, the base stage of switch controlling signal the 3rd switching tube Q3 to output control module of a high level can be exported from the first output (VO), because the 3rd switching tube Q3 is the triode of PNP, so the 3rd switching tube Q3 ends.And the grid of the first switching tube Q1 is connected with the emitter of the 3rd switching tube Q3, now the grid of the first switching tube Q1 is high level, first switching tube Q1 is a N-channel MOS FET, understands conducting, now the first switching tube Q1 conducting when the voltage of grid is greater than cut-in voltage; The grid of described first switching tube Q1 and source electrode () between the first electric capacity C1 of connecting be filter capacitor, can restraint speckle, make the grid voltage of the first switching tube Q1 more stable.On the contrary, when signal acquisition module does not collect the infrared signal of change, output is not had vicissitudinous voltage signal by described signal acquisition module, signal processing module can export a low level switch controlling signal to output control module, corresponding, 3rd switching tube Q3 conducting, and the first switching tube Q1 ends.
When the 3rd switching tube Q3 ends, and during the first switching tube Q1 conducting, after the drain electrode of the first switching tube Q1 is connected with the first resistance R1, be connected to the negative pole of fluorescent tube through the 3rd link of switching circuit unit, and the source ground of the first switching tube Q1.Please refer to shown in Fig. 4, at the output of lamp tube drive circuit, be connected with a feedback resistance Rdz, this feedback resistance Rdz is connected to negative pole and the ground end of fluorescent tube.Now, in the circuit that switching circuit unit is connected with fluorescent tube, in parallel with feedback resistance Rdz again after being equivalent to the first switching tube Q1 and the first resistance R1 series connection, namely equal the first resistance R1 and feedback resistance Rdz in parallel.Further, when described first resistance R1 is equal with the resistance of the feedback resistance Rdz of lamp tube drive circuit, total feedback resistance of fluorescent tube just reduces half, and corresponding power output just increases one times, and fluorescent tube is in complete bright state.Accordingly, when the 3rd switching tube Q3 conducting, and when the first switching tube Q1 ends, total feedback resistance of fluorescent tube only has feedback resistance Rdz, the corresponding power output of fluorescent tube is constant, and fluorescent tube is in half bright state (state when being feedback resistance Rdz total feedback resistance is decided to be half bright state of fluorescent tube).
By aforementioned reasoning, fluorescent tube can be controlled with the conducting of the first switching tube Q1 and be in complete bright state, and control fluorescent tube with the cut-off of the first switching tube Q1 and be in half bright state.Certainly, according to the needs of illumination, the brightness of described fluorescent tube might not be complete bright state, and namely the brightness of fluorescent tube is adjustable; Now, only need the resistance of the feedback resistance Rdz controlling described first resistance R1 and lamp tube drive circuit, lighting tube brightness can be realized by the half bright adjustment to any brightness between entirely bright.
When SP3T slide switch is switched to STRONG shelves, described signal processing module is de-energized, and do not form electrical connection with the second gear STRONG, signal processing module is in the state of quitting work, and namely cannot carry out reception and the output services of signal.Now, the second gear is electrically connected with the base stage of the 3rd switching tube Q3 in switching circuit unit, and the base stage of the 3rd switching tube Q3 is forced to add high level.Being switched to SENSOR gear according to aforementioned SP3T slide switch analyzes known, when the base stage of the 3rd switching tube Q3 is high level, 3rd switching tube Q3 ends, and the first switching tube Q1 conducting, namely switching circuit unit is forced conducting, at this moment nobody no matter is had to move in the induction range of infrared induction parts, the power output of fluorescent tube (LED infrared induction lamp) all can increase, achieve the state making fluorescent tube always be in blast, be applied to solution of emergent event and need to allow the situation of fluorescent tube blast in long-time, facilitate the illumination of pedestrian.Further, when described first resistance R1 is equal with the resistance of the feedback resistance Rdz of lamp tube drive circuit, fluorescent tube is in complete bright state.
When SP3T slide switch is switched to WEAK shelves, described signal processing module is de-energized, and does not form electrical connection with third gear WEAK, and signal processing module is in the state of quitting work, and namely cannot carry out reception and the output services of signal.Now, third gear is electrically connected with the base stage of second switch pipe Q2 in switching circuit unit, and the base stage of second switch pipe Q2 is forced to add low level, because second switch pipe Q2 is the triode of NPN, so second switch pipe Q2 ends.Now, 3rd resistance R3 and the 4th resistance R4 forms series circuit, by controlling the resistance size (R4 must be met much smaller than R3) of the 3rd resistance R3 and the 4th resistance R4, such as the resistance of the 3rd resistance R3 is 10K, and the resistance of the 4th resistance R4 is 1K, to the low level that the base stage one of the first switching tube Q1 is stable, the first switching tube Q1 is ended, switching circuit unit is forced to turn off.Being switched to SENSOR gear according to aforementioned SP3T slide switch analyzes known, when the first switching tube Q1 ends, total feedback resistance of fluorescent tube only has feedback resistance Rdz, the corresponding power output of fluorescent tube is constant, and fluorescent tube is in half bright state (state when being feedback resistance Rdz total feedback resistance is decided to be half bright state of fluorescent tube).At this moment nobody no matter is had to move in the induction range of infrared induction parts, the power output of fluorescent tube (LED infrared induction lamp) all can be constant, achieve and make fluorescent tube be in the constant state of brightness always, be applied to solution of emergent event and need to allow the fluorescent tube situation that brightness is constant in for a long time, save energy consumption.
Further, described human motion induction light adjusting and controlling device also comprises filter unit, and one end of described filter unit is connected with signal acquisition module 11, and the other end is connected with signal processing module 12.Wherein, described ripple filter unit is RC filter circuit, by described RC filter circuit, the signal sensed is sent to signal processing module 12, can filters out some noise signals thus, makes the signal that senses more accurate, there will not be the phenomenon of erroneous judgement.Concrete, the design of described RC filter circuit is well known to those skilled in the art, and does not repeat them here.
Further, described human motion induction light adjusting and controlling device also comprises temperature compensation unit, and described temperature compensation unit is connected with signal processing module 12; Particularly, can be connected with the 2IN-pin of the control chip LP0001 of signal processing module 12.The main element of described temperature compensation unit is the thermistor of a negative temperature coefficient, and by the resistivity-temperature characteristics of thermistor, guarantee that signal acquisition module is under different temperature conditions, its distance of reaction is consistent.This is because the output signal strength of infrared induction parts can increase with the reduction of ambient temperature, and negative tempperature coefficient thermistor can increase by resistance with the reduction of temperature, the multiplication factor of the voltage signal of the control chip LP0001 being sent to signal processing module is reduced, the situation that the lucky like this output signal strength that compensate for infrared induction parts can increase with the reduction of ambient temperature, ensure that the consistency of distance of reaction at varying environment temperature.
Further, described signal processing module comprises timing unit, and the switch controlling signal that described timing unit is used for signal processing module breaker in middle control signal output exports carries out time delay, and switch controlling signal is continued for some time.Particularly, described timing unit is realized by RC timing circuit, by the design to resistance value in timing circuit and capacitance, can realize the time delay of random time length, and concrete circuit design is known for those skilled in the art, no longer describes.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
