A sensing circuit 70 is coupled to the microprocessor 40. The sensing circuit 70 senses changes in the external environment and transmits an inductive signal to the microprocessor 40 to cause the microprocessor 40 to control the switching circuit 60 to be turned on or off. The LED Light set 50.

A brightness setting unit 80 is connected to the microprocessor 40 so that the user can set the maximum light level of the LED light group 50 via the brightness setting unit 80. 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

The user applies the operation at the power source 10, and sets the system of the present invention to the manual operation mode 401. At this time, in the corresponding switch-on setting 4011 of the processor 40, the LED light group 50 is set to accept only the manual operation of the user. The state in which the LED lamp group 50 emits light or does not emit light is determined.

The following describes the circuit configuration of one of the practices in this case. The circuit configurations that can achieve the above functions are all within the scope of the present invention and are not limited by the following embodiments.

Referring to FIG. 3, a schematic block diagram of a control circuit for a moving object-sensing LED lamp for implementing various illumination functions includes an LED lighting circuit and a sensing circuit 70 for implementing various illumination functions, and a power supply 10 for driving the LED lighting circuit. In this example, the LED driving power source 10) and the power source driving circuit 30 are provided. The LED lighting circuit includes a waveform generator 20 (in this example, the optical coupling circuit 20), a microprocessor 40 connected to the optical coupling circuit 20, and an LED lamp group 50 connected to the microprocessor 40. A switch circuit 60 connected to the LED lamp set 50 for driving the LED lamp set 50, and a power supply drive circuit 30 for supplying the drive power to the microprocessor 40 and the LED lamp set 50. As shown in FIG. 4, the sensing circuit 70 includes a photosensitive sensor 71 and a moving object sensing circuit 72 respectively connected to the microprocessor 40, wherein the photosensitive sensor 71 is used to sense the ambient light intensity, and the moving object sensing circuit 72 It is used to sense the signal from an external object. Specifically, the moving object sensing circuit 72 further includes a radio wave sensor 722 and a pair of signal amplifiers 721 for amplifying the signals induced by the radio wave sensor 722. The LED light group is changed according to the external sensing signal by the sensing circuit and the photosensitive sensor, and the light emitting mode of the LED light group is controlled by the microprocessor to realize the lighting function of the ordinary LED light and the lighting control during the day and night. real The control function is now slightly lit at night.

Specifically, as shown in FIG. 5, the input end of the optical coupling circuit 20 is connected to the LED driving power source 10, and the output end is connected to the first signal input terminal 41 of the microprocessor 40. 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 second signal input end 43 of the microprocessor is connected to the photo sensor 71, and the third signal input end 42 is connected to the sensing circuit, specifically connected to the signal amplifier 721 in the sensing circuit. The photosensitive sensor 71 outputs a square wave signal to the second signal input terminal 43 by sensing the ambient light intensity, and the sensing circuit outputs a square wave signal to the third signal input terminal 42 after sensing the signal from the external object.

The terminal outputs a control signal to control the on and off of the switch circuit 60. 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.

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.

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.

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.

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.

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. That is, the above manual operation mode 401, see FIG. 1 and FIG. In the present case, the LED lamp group can be selected from cool white light, warm light and white light. In this embodiment, a set of LED lights is selected, that is, LED11-LED1N is selected as cold light, and the LED11 positive electrode in the LED light group is respectively connected with the positive electrode of the output end of the power drive circuit, and the power source is connected. The positive terminal of the output of the driving circuit is also the positive terminal of the output of the AC to DC circuit.

In this embodiment, the switch circuit 60 is a field effect transistor, and the D pole of the field effect transistor is connected to the negative electrode of the LED lamp group 50, and the S pole of the field effect transistor and the output end of the power drive circuit The negative electrode is connected, and the G-pole of the field effect transistor is connected to the pulse width modulation signal output terminal of the microprocessor 40. 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.

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.

The above steps are explained and described in detail below.

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.

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.

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.

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.

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.

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. The LED light group emits light, realizes the automatic control of the LED light group illumination, and achieves the purpose of energy saving and environmental protection. And the enhanced LED lighting function, LED lighting is more intelligent, which is conducive to the application and promotion of LED lighting products.

The moving object induction light source control system of the present invention can be widely applied to bulb lamps, downlights, ceiling lamps, fluorescent tubes, panel lamps, ceiling lamps, PAR lamps, corn lamps, oil lamps, mining lamps, etc. The requirements can be changed at will, and the driving power can be adjusted according to the power required by the LED lighting to adapt to the power required by various lamps.
