The brightness setting unit 80 is connected to the brightness storage 81 of the processor 40. Referring to FIG. 1 and FIG. 2, the operation mode of the present invention is as follows: the manual operation mode 401
使用者應用在該電源10處的操作,而將本案的系統設定於手動操作模式401,此時在處理器40之對應的開關開啟設定4011中設定該LED燈組50僅接受使用者的手動操作而決定該LED燈組50的發光或不發光的狀態。此時驅動訊號經由該波形產生器20進入該微處理器40,然後由該微處理器40控制該開關電路60以開啟或關斷該LED燈組50。而該感應電路70並不作用。 The user applies the operation at the power source 10, and sets the system of the present invention to the manual operation mode 401.

自動調整操作模式403 Automatic adjustment operation mode 403
在感應操作模式402下,使用者應用在該電源10處的操作,而將本案的系統設定於自動調整操作模式403,係當感側的環境中沒有偵測到移動物體時,此時在處理器40之對應的開關開啟設定4031中設定該LED燈組50的亮度可以隨著時間自動調整。如當本案的燈組使用在停車場時,當停車場沒有移動物體時,該LED燈組50的亮度可以隨著時間慢慢降低,如原來為發80%的亮度,一分鐘後減為50%的亮度,再一分鐘後減為20%的亮度,以達到節省能源的目的。 In the sensing operation mode 402, the user applies the operation at the power source 10, and sets the system of the present invention to the automatic adjustment operation mode 403.

The brightness is reduced to 20% brightness in one minute to save energy.
本案中該感應電路70可包含下列兩種感應器:一移動物體感應電路72,用於感應外界物體是否經過,而將所感應的訊號傳送到該微處理器40,以令該微處理器40控制該開關電路60而開啟或關閉該LED燈組50。其中該移動物體感應電路72包含一無線電波傳感器722,用於感應所發射的無線電波(如紅外線、RF)是否有被遮斷,並將所感應的訊號傳送到後級的信號放大器721,以將訊號放大並送到該微處理器40。 In the present case, the sensing circuit 70 can include the following two types of sensors: a moving object sensing circuit 72 for sensing whether an external object passes, and transmitting the sensed signal to the microprocessor 40 to cause the microprocessor 40 to The switch circuit 60 is controlled to turn the LED light unit 50 on or off. The mobile object sensing circuit 72 includes a radio wave sensor 722 for sensing whether the transmitted radio waves (such as infrared rays, RF) are blocked, and transmitting the induced signals to the signal amplifier 721 of the subsequent stage. The signal is amplified and sent to the microprocessor 40.
其中該無線電波傳感器722可為紅外線傳感器或RF電波傳感器。 The radio wave sensor 722 can be an infrared sensor or an RF wave sensor.
一光敏傳感器71可用於感應外界的光強度,不同的光強度會使得該光敏傳感器71產生不同的驅動電流,並將該驅動電流送到該微處理器40。 A photosensor 71 can be used to sense the intensity of the outside light. Different light intensities cause the photosensor 71 to generate different drive currents and send the drive current to the microprocessor 40.
該微處理器40接受來自該光敏傳感器71的驅動電流後,判斷該驅動電流的大小,並參考來自該亮度設定單元80的設定值,以決定該LED燈組50所需的發光亮度,並藉以驅動該開關電路60以使得該LED燈組50發出所需的發光亮度。 After receiving the driving current from the photosensor 71, the microprocessor 40 determines the magnitude of the driving current and refers to the setting value from the brightness setting unit 80 to determine the brightness of the LED lamp group 50 required for illumination. The switch circuit 60 is driven to cause the LED light set 50 to emit a desired luminance of illumination.
如使用者經由該亮度設定單元80設定的發光亮度為80流明,而經由該光敏傳感器71的環境亮度為30流明,此時該微處理器40驅動該開關電路60以使得該LED燈組50發出50流明的發光亮度。 If the brightness of the light set by the user via the brightness setting unit 80 is 80 lumens, and the ambient brightness of the light sensor 71 is 30 lumens, the microprocessor 40 drives the switch circuit 60 to cause the LED light group 50 to emit 50 lumens of luminous brightness.
因此當在感應操作模式402時,本案之系統先由該移動物體感應電路72決定是否有人或移動物體進入照明空間。當有人或移動物體進入照明空間時,該處理器40開啟該燈源。然後由該光敏傳感器71決定該照明空間的亮度,並傳送到該處理器40。該處理器40將來自該亮度設定單元80的設定值減去環境亮度即可得到該LED燈組50應有的發光亮度。 Therefore, when in the sensing mode of operation 402, the system of the present invention first determines whether a person or moving object enters the lighting space by the moving object sensing circuit 72. The processor 40 turns on the light source when a person or moving object enters the lighting space. The brightness of the illumination space is then determined by the photosensor 71 and transmitted to the processor 40. The processor 40 subtracts the ambient brightness from the set value of the brightness setting unit 80 to obtain the brightness of the LED lamp group 50.

The optical coupling circuit 20 generates the photoelectricity through the LED driving power source 10. The coupled signal, in the present embodiment, the photocoupled signal is a square wave signal. Therefore, the signal received by the first signal input 41 of the microprocessor 40 is a square wave signal.

The switch circuit 60 is connected to the LED lamp set 50 for driving the illumination of the LED lamp set 50. The power drive circuit 30 is connected to the microprocessor 40 and the LED lamp set 50, respectively, to provide drive current thereto.
為了更加清晰的描述上述實現多種照明功能的移動物體感應LED燈的控制電路,本案以具體的實施例進行詳細的說明。 In order to more clearly describe the above control circuit for the moving object-sensing LED lamp that realizes various illumination functions, the present invention will be described in detail with reference to specific embodiments.
請參見圖5,電源驅動電路30包括一交流轉直流(AD 轉DC)電路31和穩壓(LDO)電路32,其中電路32的輸入端,穩壓電路32的輸出端連接微處理器40的電壓輸入端,為微處理器40提供工作電壓Vcc,該穩壓電路32為低壓差線性穩壓積體電路。交流轉直流電路31將LED驅動電源10提供的交流電轉換為直流電,並產生恆壓恆流信號。電壓和電流的大小可以通過交流轉直流電路31進行調節。交流轉直流電路31的輸出端還與LED燈組50相連,為LED燈組50提供工作電源。 Referring to FIG. 5, the power driving circuit 30 includes an alternating current to direct current (AD). The DC circuit 31 and the voltage regulator (LDO) circuit 32, wherein the input of the circuit 32, the output of the voltage regulator circuit 32 is connected to the voltage input terminal of the microprocessor 40, and the operating voltage Vcc is supplied to the microprocessor 40. The voltage circuit 32 is a low-dropout linear voltage regulator integrated circuit. The AC-DC circuit 31 converts the AC power supplied from the LED drive power source 10 into DC power and generates a constant voltage constant current signal. The magnitude of the voltage and current can be adjusted by the AC to DC circuit 31. The output of the AC-DC circuit 31 is also connected to the LED lamp set 50 to provide operating power for the LED lamp set 50.
而光耦合電路20的兩個輸入管腳分別連接在LED驅動電源10的兩相上,光耦合電路20的其中一輸出管腳連接微處理器40的信號輸入端,也即是微處理器MCU的AD1埠,該AD1埠是微處理器40的一模數轉換埠,由於光耦合電路20輸出的信號為脈波信號。因此,為了便於後續通過微處理器40對開關電路進行通斷控制,光耦合電路20的該輸出端需接微處理器40的該AD1埠,以將類比信號轉換為數位信號。光耦合電路20的另一輸出端連接電源驅動電路30的輸出端負極。 The two input pins of the optical coupling circuit 20 are respectively connected to two phases of the LED driving power source 10. One of the output pins of the optical coupling circuit 20 is connected to the signal input end of the microprocessor 40, that is, the microprocessor MCU. AD1埠, the AD1埠 is an analog-to-digital conversion of the microprocessor 40, and the signal output from the optical coupling circuit 20 is a pulse wave signal. Therefore, in order to facilitate the on/off control of the switching circuit by the microprocessor 40, the output of the optical coupling circuit 20 needs to be connected to the AD1 of the microprocessor 40 to convert the analog signal into a digital signal. The other output of the optical coupling circuit 20 is connected to the negative terminal of the output of the power supply driving circuit 30.
光耦合電路20向微處理器AD1埠輸出的方波信號的產生過程如下:光耦合電路20的輸入管腳接在交流電的火線和零線兩端,當交流電正半周流過光耦合電路20中發光二極體的正極時,該發光二極體開始發光,使裡面的電晶體導通, AD1埠的信號從原來的高電位變為低電位,當交流電為負半周流過時,發光二極體截止工作,發光二極體不發光使電晶體不導通,進而使AD1埠的信號從原來的低電位變為高電位,這樣不斷有交流電流過光耦合電路的輸入管腳,使輸出端管腳輸出方波信號。 The process of generating the square wave signal outputted by the optical coupling circuit 20 to the microprocessor AD1 is as follows: the input pin of the optical coupling circuit 20 is connected to both the live line and the neutral line of the alternating current, and flows through the optical coupling circuit 20 when the alternating current is positively half-circumferential. When the positive electrode of the light-emitting diode is turned on, the light-emitting diode starts to emit light, so that the transistor inside is turned on. The signal of AD1埠 changes from the original high potential to the low potential. When the alternating current flows for the negative half cycle, the light-emitting diode is turned off, and the light-emitting diode does not emit light, so that the transistor does not conduct, and thus the signal of AD1埠 is from the original. The low potential becomes high, so that the alternating current flows through the input pin of the optical coupling circuit, so that the output terminal outputs a square wave signal.
優選地,本案移動物體感應LED燈可實現普通照明LED燈的控制,白天晚上控制功能,微亮功能的控制電路能夠使一個產品既可以當移動物體感應LED燈使用,也可以當普通LED燈泡用,即為上述之手動操作模式401,參見圖1及圖2。在本案中,LED燈組可以選用冷白光、暖光和白光,本實施例選用一組LED燈即選取LED11-LED1N為冷光,LED燈組中LED11正極分別與電源驅動電路輸出端的正極相連,電源驅動電路的輸出端正極也即是交流轉直流電路輸出端的正極。 Preferably, the moving object-sensing LED lamp of the present invention can realize the control of the general illumination LED lamp, the day and night control function, and the control function of the micro-light function can enable a product to be used as a moving object to sense an LED lamp or as a general LED bulb.

The pulse width modulation signal output end of the microprocessor 40 provides a pulse width modulation signal to the field effect transistor to control the on and off of the field effect transistor. The pulse width modulation signal output end of the microprocessor 40 continuously generates a pulse width modulation signal to drive the field effect transistor Body, driving the LED light group to illuminate.
基於上述實現多種照明功能的移動物體感應LED燈的控制電路,本案還提供了實現多種照明功能的移動物體感應LED燈的控制方法(即為上述之感應操作模式402,參見圖1及圖2),具體的實現過程請參見圖6,包括以下步驟:步驟S100、感應電路檢測外部感應信號,並當所述感應電路感應不到外部的感應信號時,微處理器控制LED燈組不發光或微亮發光;步驟S200、當所述感應電路檢測到外部的感應信號時將所述感應信號發送給微處理器,所述微處理器根據所述感應信號的強度變化,調整向LED燈組輸出的脈衝調製信號的強度,以驅動所述LED燈組根據所述感應信號的強度變化發出不同強度的光。 Based on the above-mentioned control circuit for the moving object-sensing LED lamp that realizes various illumination functions, the present invention also provides a control method for the moving object-sensing LED lamp that realizes various illumination functions (ie, the above-described sensing operation mode 402, see FIG. 1 and FIG. 2). Referring to FIG. 6 , the specific implementation process includes the following steps: Step S100: The sensing circuit detects an external sensing signal, and when the sensing circuit does not sense an external sensing signal, the microprocessor controls the LED light group to not emit light or micro. Illuminating light; step S200, sending the sensing signal to the microprocessor when the sensing circuit detects an external sensing signal, and the microprocessor adjusts the output to the LED light group according to the intensity change of the sensing signal The intensity of the pulse modulated signal is used to drive the LED light group to emit light of different intensities according to the intensity change of the sensing signal.
下面對上述步驟進行詳細的說明和描述。 The above steps are explained and described in detail below.
其中,在步驟S100中,感應信號包括光敏傳感器感應到的環境光線強度信號,以及無線電波傳感器感應到的信號。在具體實施時,首先電源驅動電路接通外接交流電開始工作,向所述微處理器、LED燈組輸出恆壓恆流信號;所述光耦合電路向所述微處理器的控制信號輸入端輸出方波信號,並經所述微處理器向所述開關電路輸出脈寬調製信號,驅動 所述開關電路導通,並控制所述LED燈組發光。 Wherein, in step S100, the sensing signal includes an ambient light intensity signal sensed by the photosensitive sensor and a signal sensed by the radio wave sensor. In a specific implementation, first, the power driving circuit turns on the external alternating current to start working, and outputs a constant voltage constant current signal to the microprocessor and the LED lamp group; the optical coupling circuit outputs to the control signal input end of the microprocessor. a square wave signal, and outputting a pulse width modulation signal to the switching circuit via the microprocessor, driving The switch circuit is turned on and controls the LED light group to emit light.
其中,當在第一預定時間(通常為1-2秒鐘)內連續兩次切換交流開關,光耦輸出端產生連續兩個方波信號,送到微處理器的AD1口輸入端,微處理器內部判斷連續有兩個方波信號輸入,則微處理器輸出脈寬調製信號去驅動Q1的G極.使Q1導通,使LED燈組發光。此時,移動物體感應LED燈的白天晚上控制的控制功能和移動物體感應控制的控制功能失效,LED發光裝置處於長亮狀態,其作為普通LED照明產品用,也即是按照正常模式發光。此時,感應電路預設為一直檢測到有外部的感應信號。 Wherein, when the AC switch is switched twice in the first predetermined time (usually 1-2 seconds), the optocoupler output generates two consecutive square wave signals, which are sent to the input terminal of the AD1 port of the microprocessor, and the micro-processing The internal judgment of the device has two square wave signal inputs, and the microprocessor outputs a pulse width modulation signal to drive the G pole of Q1. The Q1 is turned on to make the LED light group emit light. At this time, the control function of the daytime night control of the moving object sensing LED lamp and the control function of the moving object sensing control are invalid, and the LED lighting device is in a long bright state, which is used as an ordinary LED lighting product, that is, it emits light according to the normal mode. At this time, the sensing circuit is preset to always detect an external sensing signal.
而如果在此情況下,在第二預定時間(通常為1-2秒鐘)內再切換一次交流開關,該LED感應照明控制電路和白天晚上控制電路啟動,進入感應模式,在該模式下可以通過感應環境光線強度和外界物體的信號來控制LED燈組發光。當在LED燈組發光時感應電路已經工作,此時感應電路會將檢測到的感應信號發送給微處理器,以便微處理器根據感應信號的強度變化,調整其向LED燈組輸出相應強度的脈衝調製信號的強度,以驅動所述LED燈組根據所述感應信號的強度變化而發出不同強度的光,優選地,微處理器向LED燈組輸出相應強度的脈衝調製信號的強度隨所述感應信號的強度增大而增大,減小而減小。 And if in this case, the AC switch is switched again within the second predetermined time (usually 1-2 seconds), the LED induction lighting control circuit and the day and night control circuit are activated to enter the sensing mode, in which the mode can be The LED light group is controlled to emit light by sensing ambient light intensity and signals from external objects. When the LED circuit is illuminated, the sensing circuit has been operated, and the sensing circuit sends the detected sensing signal to the microprocessor, so that the microprocessor adjusts the intensity of the sensing signal to the LED lamp group according to the intensity change of the sensing signal. The intensity of the pulse modulation signal is to drive the LED lamp group to emit light of different intensity according to the intensity change of the sensing signal. Preferably, the microprocessor outputs the intensity of the pulse modulation signal of the corresponding intensity to the LED lamp group. The intensity of the induced signal increases and decreases, and decreases.
具體地,通過感應外界物體的信號控制LED燈組發光的過程為:當有人或流動車輛經過感應區內,無線電波傳感器會發出微弱的高電平50mVdc-100mVdc之間,此信號再送到信號放大器輸入端進行信號放大後輸出一個高電平,再送到微處理器感應信號輸入端,這時微處理器感應信號輸入端接收到高電平時,從微處理器內部輸出脈寬調製信號去驅動Q1的G極.使Q1導通,控制LED燈組發光。而當無人或無流動車輛經過感應區內,無線電波傳感器不會發出微弱的高電平,後級信號放大器輸入端沒有信號,放大器無高電平輸出,微處理器感應信號輸入端,無感應信號,這時微處理器內部無輸出脈寬調製信號去驅動Q1的G極.使Q1無法導通,則LED燈組無法發光。 Specifically, the process of controlling the illumination of the LED lamp group by sensing the signal of the external object is: when a person or a mobile vehicle passes through the sensing region, the radio wave sensor emits a weak high level between 50 mVdc and 100 mVdc, and the signal is sent to the signal amplifier. The input terminal performs signal amplification and outputs a high level, and then sends it to the microprocessor sensing signal input terminal. At this time, when the microprocessor senses the signal input terminal to receive a high level, the pulse width modulation signal is output from the microprocessor to drive the Q1. G pole. Turn Q1 on and control the LED light group to emit light. When the unmanned or no-flowing vehicle passes through the sensing area, the radio wave sensor will not emit a weak high level, the signal input at the rear stage signal amplifier has no signal, the amplifier has no high-level output, and the microprocessor senses the signal input terminal without induction. Signal, at this time there is no output pulse width modulation signal inside the microprocessor to drive the G pole of Q1. If Q1 cannot be turned on, the LED light group cannot emit light.
進一步地,實現白天或晚上的發光控制功能以及微亮控制功能是通過探測環境光線強度控制LED燈組發光的過程為:當環境光線強度高於微處理器內部一預定值時,該預定值優選為20流明,光敏傳感器開始工作,這時光敏傳感器的內阻比較低,輸出的電壓送到微處理器信號輸入端,微處理器內部有一個參考電壓計算,當信號輸入端輸入的電壓低於0.8Vdc時,微處理器判斷這時環境光線強度高於20流明,當前時間為白天,這時微處理器內部無輸出脈寬調製信號去驅動Q1的G極,使Q1無法導通,使LED燈組無法發光。而 當環境光線強度低於20流明時,光敏傳感器開始工作,這時光敏傳感器的內阻比較高,輸出的電壓送到微處理器的信號輸入端,當信號輸入端輸入的電壓高於1Vdc時,微處理器判斷這時環境光線強度低於20流明,當前時間為晚上,這時微處理器內部輸出脈寬調製信號只輸出10%的脈寬調製信號去驅動Q1的G極,使Q1導通輸出LED實際功率的一預定比例,控制LED燈組處於微亮發光狀態。等待有人或流動熱量物體進入探測範圍內,根據感應信號的從弱到強的變換,LED燈組的發光強度也在一預定範圍內從小到大進行變化。本實施例中,預定比例優選為10%,預定範圍為10%至100%。這樣解決了傳統LED移動物體感應燈不能完成在晚上無人或無流動熱量物體處於全黑的狀況,而且解決了在一個移動物體感應LED燈上面完成白天晚上控制功能和晚上微亮控制功能。只亮10%的微亮狀態帶來的好處是使在夜間安防攝像頭更清晰的拍到環境的畫面避免在全黑狀態安防攝像頭無法拍清楚周圍環境的圖片。 Further, the daylight or night illumination control function and the microlight control function are used to control the illumination of the LED lamp group by detecting the ambient light intensity: when the ambient light intensity is higher than a predetermined value inside the microprocessor, the predetermined value is preferably For 20 lumens, the photosensor starts to work. At this time, the internal resistance of the photosensor is relatively low. The output voltage is sent to the microprocessor signal input terminal. There is a reference voltage calculation inside the microprocessor. When the input voltage of the signal input terminal is lower than 0.8. When Vdc, the microprocessor judges that the ambient light intensity is higher than 20 lumens, and the current time is daytime. At this time, there is no output pulse width modulation signal inside the microprocessor to drive the G pole of Q1, so that Q1 cannot be turned on, so that the LED light group cannot be illuminated. . and When the ambient light intensity is lower than 20 lumens, the photosensitive sensor starts to work. At this time, the internal resistance of the photosensitive sensor is relatively high, and the output voltage is sent to the signal input end of the microprocessor. When the input voltage of the signal input terminal is higher than 1Vdc, the micro The processor judges that the ambient light intensity is lower than 20 lumens, and the current time is night. At this time, the internal pulse width modulation signal of the microprocessor outputs only 10% of the pulse width modulation signal to drive the G pole of Q1, so that Q1 turns on the actual power of the LED. A predetermined ratio controls the LED light group to be in a slightly bright state. Waiting for someone or a flowing heat object to enter the detection range, according to the weak to strong change of the sensing signal, the luminous intensity of the LED lamp group also changes from small to large within a predetermined range. In the present embodiment, the predetermined ratio is preferably 10%, and the predetermined range is 10% to 100%. This solves the problem that the traditional LED moving object induction lamp can not complete the black or the no-flowing heat object at night, and solves the day and night control function and the night light-light control function on a moving object-sensing LED lamp. The only benefit of only 10% of the bright state is that the security camera at night can be used to capture the picture more clearly. In the all black state, the security camera cannot take pictures of the surrounding environment.
這樣通過不斷地控制交流開關斷開交流電,環境光線照度處於晚上或白天時不僅實現了一個移動物體感應LED燈作為普通照明燈具的照明功能,而且還實現了在同一個移動物體感應LED燈發光裝置上同時實現白天晚上控制功能和微亮控制功能,通過感應環境光線強度和外界物體的信號來控制 LED燈組發光,實現了LED燈組發光的自動控制,達到節能環保的目的。且增強的LED的照明功能,LED照明更加智慧化,利於LED照明產品的應用和推廣。 In this way, by continuously controlling the AC switch to disconnect the AC power, the ambient light illumination is at night or during the daytime, not only realizes a moving object-sensing LED lamp as an illumination function of an ordinary lighting fixture, but also realizes an LED light-emitting device that senses the same moving object. Simultaneously implement day and night control functions and light-light control functions, which are controlled by sensing ambient light intensity and signals from external objects.

And the enhanced LED lighting function, LED lighting is more intelligent, which is conducive to the application and promotion of LED lighting products.
