Description
Technical field
This utility model relates to field of light fittings, is specifically related to a kind of microwave induced dimmer of LED.
Background technology
Microwave LED drive power is used to replace the power supply of human body infrared sensing, microwave induced advantage is highly sensitive, induction area width, penetration capacity is strong, and inductive head in use have to be leaked outside by human body infrared sensing, not so cannot sense or induced signal weakens the effect of the switch that causes losing induction significantly；And it is more weak to penetrate ironwork ability.
It is microwave induced that we use microwave Doppler effect detection principle.In Doppler effect, the concrete principle of Doppler frequency shift is: unit is own or/and the frequency shift caused by object relative motion is referred to as Doppler frequency shift because presenting for electromagnetic wave or frequency of sound wave, or claims Doppler effect.Stand in railway platform and hear that the phenomenon of the train whistle modulation that enters the station is exactly that best Doppler effect is experienced.When train is met you and come, the frequency of steam whistle can improve, and sound comes to a point, and vice versa.Being learnt by Doppler effect, the fixed frequency microwave that hard-wired radar sends, its frequency of echo running into stationary object generation does not change, and the echo running into moving object generation will occur Doppler frequency shift.
Along with the scale of microwave semiconductor technology is applied, the physics realization of microwave technology is the simplest, cheap；And volume is the least to such an extent as to can put the microwave remote sensor of matchbox size in various object detection device into, therefore also becomes assembly common in target detection unit.Compared with Infrared Detectors, this microwave components to various can be the most very sensitive with the object of microwave reflection, and do not affected by ambient temperature, in LED power product, microwave detector uses this microwave remote sensor more more stable than human body infrared.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, this utility model provides the microwave induced dimmer of LED of a kind of energy-saving and environment friendly.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of microwave induced dimmer of LED, it is characterized in that: include microwave induced module, microcontroller and LED power, described LED power outfan is connected with microwave induced module and microcontroller successively, and described microcontroller outfan is connected with LED power.
As the improvement of technique scheme, described LED power uses exchange AC100-250V.
As the improvement of technique scheme, described microwave induced module includes sending and receiving apparatus.
As the improvement of technique scheme, described sending and receiving apparatus includes antenna, microwave oscillator, difference amplifier and voltage comparator.
As the improvement of technique scheme, described antenna is connected with microwave oscillator, difference amplifier respectively, and described difference amplifier is connected with voltage comparator.
As the improvement of technique scheme, described microcontroller includes LED luminance adjustment module, and described LED luminance adjustment module is by the brightness of LED power regulation LED.
As the improvement of technique scheme, when microwave induced module detects target movable signal, LED luminance is full brightness, and when microwave induced module is not detected by target movable signal, LED luminance is 30% full brightness.
The beneficial effects of the utility model are: a kind of microwave induced dimmer of LED, nobody with in the case of not having vehicle to move, the brightness of all light fixtures in garage all remains the 30% of its maximum brightness, to maintain the normal brightness demand of monitoring device, the consumption to the energy is farthest reduced, it is achieved energy-conserving and environment-protective with this.
In underground garage, by microwave remote sensor, detect whether that vehicle or personnel move.If be detected that there is the movement of vehicle or personnel, LED lamp is lit, if there is target to move in investigative range always, then LED lamp is persistently lit, and otherwise enters green energy conservation pattern, it is achieved intellectuality saves lighting.
Accompanying drawing explanation
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings:
Fig. 1 is the structured flowchart of this utility model specific embodiment；
Fig. 2 be this utility model specific embodiment microwave induced module in sending and receiving apparatus structured flowchart.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further details:
With reference to Fig. 1, a kind of microwave induced dimmer of LED, including microwave induced module, microcontroller and LED power, described LED power outfan is connected with microwave induced module and microcontroller successively, and described microcontroller outfan is connected with LED power input.Described LED power voltage range is AC100-250.
With reference to Fig. 2, described microwave induced module includes sending and receiving apparatus, and sending and receiving apparatus includes antenna, microwave oscillator, difference amplifier and voltage comparator.Described antenna is connected with microwave oscillator, and described antenna is connected with difference amplifier, and described difference amplifier is connected with voltage comparator.
The target movable signal detected is passed to microcontroller by described microwave induced module, the pwm control signal that microcontroller output is different, controlling the driving electric current of LED drive module, LED power provides power supply to allow microwave induced module be in operating conditions to microwave induced module.If there being target to move in induction range, when having microwave signal to trigger microwave board when, microwave induced module sends signal to microcontroller, microcontroller starts after receiving microwave signal process and provide pwm signal to LED power, makes power supply be controlled by microwave signal and reaches the requirement that brightness changes.Microcontroller includes LED luminance adjustment module, and described LED luminance adjustment module is by the brightness of LED power supply regulation LED.The lamp body brightness full brightness 100% when having human body to pass through or to have people's activity in microwave range, people leaves rear brightness and becomes 30% full brightness；So can reach energy-saving effect.
After lighting LED, microcontroller time delay a period of time, then detect in induction range and whether to also have target to move, if still there being target to move, then LED persistently lights；If being not detected by target after time delay to move, then microcontroller output pwm control signal, controls LED power electric current thus regulates the brightness of LED.
It is above the preferably enforcement of utility model is illustrated, but utility model is created and is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement on the premise of this utility model spirit, and modification or the replacement of these equivalents are all contained in the application claim limited range.
