So-called intelligent-induction control utilizes the environment that changes around the various sensor sensings exactly, and controller is according to the functions such as switch of the Data Control LED lighting device that collects.
The moment sensor technology has been a mature technique, and stable performance is so the transducer of many types has been widely used in the LED lighting device.Transducer mainly contains the transducer of all kinds of LED of being usually used in lighting devices such as light sensation transducer, human-body infrared sensing device, acoustic control transducer.Wherein the light sensation transducer can perception surrounding environment light situation, and controller is regulated the LED lighting device according to the light situation around collecting, thereby realizes the control of intelligence.The human-body infrared sensing device is a kind of approaching control device of human body that is used for, near can accurately finding out human body near, certain distance detecting during to human body controller can control the luminous situation of LED lighting device.The acoustic control transducer through receive about one second control signal " neigh " sound, can open the LED lighting device easily, simple to operate.
In aforementioned three kinds of sensor application, independent use is arranged, the use of mutually combining is in twos also arranged.For example, light sensation transducer and human-body infrared sensing device are used in combination, though very practical on the function, the long-time LED lighting device of opening, the waste electric energy, frequent switch LED lighting device takes very much energy again.
Summary of the invention
The purpose of the utility model is for providing a kind of intelligence and energy-conservation, LED illumination intelligent controller easily.
The utility model provides a kind of LED illumination intelligent controller, comprises sensor assembly, control module, driver module and light source module.Described control module comprises information acquisition unit, data processing unit and pwm unit; Said control module connects sensor assembly and driver module; Driver module connects the light source module; It is characterized in that: said sensor assembly comprises human-body infrared sensing device and light sensation transducer, also comprises timing control unit in the said control module.
Concrete scheme does; The information acquisition unit of control module is given data processing unit and is handled, according to the various signals classification after collecting the signal that human-body infrared sensing device and light sensation sensor sensing arrive; The pulse-width signal of output gradual change; Driver module is regulated the brightness of LED light fixture according to pulse-width signal, and combines timing control unit timing switch LED light fixture, finally reaches the effect of intelligent dimming.
Further, described human-body infrared sensing device is a pyroelectric infrared sensor, and it is a kind of new sensitive element, by high Seebeck coefficient material, is equipped with filter glass and impedance matching is formed with FET.It can detect the infrared radiation that sends from human body with the noncontact mode, converts thereof into signal of telecommunication output, and can effectively suppress the interference emission beyond the human body radiation wavelength, like sunlight, light and reverberation thereof.
Further, described light sensation transducer adopts surround lighting propagated sensation sensor.It is integrated sense unit of light-receiving Lazer, micro-signal cmos amplifier, high-accuracy voltage source and correction circuit, application circuit is simple.Its electrical characteristic: dark current is little, and the low-light (level) response is highly sensitive, and electric current is linear change with the illuminance enhancing; Sense unit of built-in Lazer, the near-infrared of decaying automatically, spectral response is near the human eye function curve; Built-in micro-signal cmos amplifier, high-accuracy voltage source and correction circuit, output current is big, and operating voltage range is wide, and temperature stability is good; Optional optics nano material encapsulation, visible light transmissive, ultraviolet cutoff, near-infrared relative attenuation have strengthened the optically filtering effect; Materials such as unleaded, no cadmium, environmental protection.
Further, described information acquisition unit, data processing unit, timing control unit and pwm unit adopt SCM system to realize.Single-chip microcomputer is used simple, technology maturation, stable performance.
The beneficial effect of the utility model is: regulate the led light source module through human detection and environment bright are detected, add timing control unit simultaneously, adopt gradual manner to regulate light.When the people moved under lamp, the LED lamp brightened gradually; When long-time nobody moved under lamp, deepenings gradually such as LED lamp were until extinguishing.This device is applicable to the LED light fixture of various field and occasion easily, can effectively protect user's eyesight, improves the human visual comfort level, and simple in structure, easy for installation, the useful life that can also improve LED.
Below in conjunction with embodiment, the foregoing of the utility model is remake further detailed description by the accompanying drawing illustrated embodiment.But should this be interpreted as that the scope of the above-mentioned theme of the utility model only limits to following instance.Do not breaking away under the above-mentioned technological thought situation of the utility model, various replacements or change according to ordinary skill knowledge and customary means are made all should be included in the scope of the utility model.
Description of drawings
Fig. 1 is the signal flow block diagram of the utility model LED lighting device.
Embodiment
As shown in Figure 1, the LED lighting device overall signal flow chart of the utility model comprises sensor assembly 1, control module 2, driver module 3 and light source module 4, and the output of sensor assembly 1 is connected with control module 2.Control module 2 comprises information acquisition unit 21, data processing unit 22, timing control unit 23 and pwm unit 24, and information acquisition unit 21 functions are signals that the pick-up transducers module is transmitted; The function of data processing unit 22 is that the signal that collects is carried out treatment classification; The function of timing control unit 23 is the timing switch time; The function of pwm unit 24 is that the different pulse width signal of output is regulated constant-current driven module.Described sensor assembly 1 comprises human-body infrared sensing device 11 and light sensation transducer 12.Human-body infrared sensing device 11 on the sensor unit adopts pyroelectric infrared sensor, and light sensation transducer 12 adopts surround lighting propagated sensation sensor.
The principle of the utility model LED lighting device does; The human-body infrared sensing device 11 on the information acquisition unit 21 real-time pick-up transducers modules 1 on the control module 2 and the information of light sensation transducer 12; Human-body infrared sensing device 11 collects the infrared radiation that human body sends, through operational amplification circuit, and the high-low level signal of signal after voltage comparator circuit etc. are handled for changing; Gather judgement so micro-control unit can directly pass through IO (input and output) mouthful, the accuracy of image data is high; Light sensation transducer 12 is output as current signal; Enhancing with illuminance is linear change; The current signal that collects variation through sampling resistor converts voltage signal to, utilizes A/D (analog digital conversion) modular converter of control module 2 to read signal value, sets the switch threshold values according to light intensity.Control module 2 is through carrying out judgment processing to the data that collect; Export corresponding PWM (pulse-width modulation) drive signal according to the condition that sets; The PWM of output is in order to the control constant-current driven module, and the PWM dutyfactor value change to adopt gradual manner, and promptly the LED lighting device brightens or deepening gradually gradually switch lamp the time; Can effectively protect user's eyes like this, improve the human visual comfort level.Add timing control unit 23, when control module enabling pulse control signal was exported, timer began regularly; Judge again after a period of time to collect human-body infrared sensing device signal, exist, do not turn off the light if detect the somebody; If detect nobody after regularly finishing, continue to turn on light.
