Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
In lighting technical field, realizing intelligent lighting according to the illumination intensity of the intensity realization automatic adjustment light fixture of natural daylight is demand the most basic.Fig. 1 is the light energy distribution figure of sunlight, ordinate representation unit area energy, what can find out that energy in sunlight i.e. natural daylight concentrates the most is visible light part, therefore prior art is all said the visible light part that intrinsic selection detected energy is concentrated the most for the intensity detection of natural daylight or at least comprises visible light part, and the object of artificial light is illumination, maximize with implementation efficiency in the spectral wavelength ranges that therefore spectral wavelength ranges of artificial light also must be selected at visible ray.Artificial light must drop into detection range, and therefore this interference is inevitable.
Inventor passes through analysis design mothod, the creationary thinking set breaching prior art, the energy distribution ratio of light in natural daylight according to different spectral wavelength ranges is fixing, by the light intensity of detected energy distribution compared with the optical wavelength range of weak part, particularly near the near-infrared spectrum wavelength of visible light wave-length coverage, and calculate the intensity of natural daylight according to this light intensity meter.
Fig. 2 is the characteristic curve of existing light-sensitive element; Fig. 3 is the characteristic curve of near infrared light dependent sensor; The spectral wavelength of the near-infrared part that special selection detected energy is relatively strong realizes the detection of natural daylight intensity at the light intensity of 700nm-1100nm scope, also just say that carrying out alternative existing light-sensitive element with near infrared light dependent sensor gathers natural daylight intensity.
Fig. 4 is the block diagram of the embodiment 1 realizing the inductor being built in the method detecting natural daylight in Led, comprises power supply module 1, human motion induction module 2, movable signal amplification module 3, central processing unit 4, executive circuit module 5, Natural light intensity detection module 6, Natural light intensity signal amplify 7, control inerface 8 forms.Wherein power supply module 1 provide human motion induction module 2, movable signal amplification module 3, central processing unit 4, executive circuit module 5, Natural light intensity detection module 6, Natural light intensity signal to amplify 7, power supply required for control inerface 8, human motion induction module 2 receives human mobile signal through mixing detection, output to movable signal amplification module 3, human-induced signal's processing module that movable signal amplification module 3 passes the signal to central processing unit 4 processes, and judges whether that someone moves or nobody moves.
It is strong that Natural light intensity detection module 6 detects natural light outside, Natural light intensity signal is sent into Natural light intensity signal and amplifies 7, Natural light intensity signal amplifies 7 and Natural light intensity signal is amplified, the A/D luminosity sampling module in central processing unit 4 is sent into after amplifying, sampling module is converted to analog signal the digital signal that central processing unit can identify, sampled signal processing module in central processing unit processes, thus the intensity of extraneous light detected.In order to ensure the accuracy detected, General Requirements reads the data in a period of time, averages as the light intensity of current time.
Control inerface 8, as the interface of man-machine interaction, can arrange the complete bright time, turns off light intensity, sensitivity.
When inductor analysis is for there being people to move, when the shutoff light intensity that outside light intensity arranges higher than control inerface 8 being detected simultaneously, executive signal generation module in central processing unit 4 does not respond this movable signal, when inductor analysis is for there being people to move, when detecting that outside light intensity is less than the shutoff light intensity of control inerface 8 setting simultaneously, executive signal generation module in central processing unit 4 produces start signal, this signal outputs to executive circuit module, K switch 1, K switch 2 obtains electric-opening, AC output exports AC full wave voltage, the LED controlling to connect drives and works in complete bright state, duration of this complete bright state is by arranging complete bright Time dependent in control inerface 8, after the complete bright time arrives, executive signal generation module in central processing unit 4 produces the complete bright shutdown signal of executive circuit module, K switch 2 disconnects, thus the AC output of this inductor exports AC half-wave voltage, the LED controlling to connect drives and works in half bright state, now to start to detect natural light outside strong for Natural light intensity detection module 6, if the light intensity of current time is higher than arranging light intensity in control inerface 8, executive signal generation module in central processing unit 4 produces the shutdown signal of whole control, K switch 1 disconnects, thus the AC output of this inductor does not have voltage to export, the LED controlling to connect drives and works in closed condition, after closed condition, Natural light intensity detection module 6 lasting detection natural light outside is strong, if the light intensity of current time is lower than arranging light intensity in control inerface 8, executive signal generation module in central processing unit 4 produces half bright start signal of executive circuit module 5, K switch 1 is opened, thus the AC output of this inductor exports half-wave voltage, LED connect below drives and works in half bright state, realize the effect of LED matrix environmentally natural daylight automatic switch.
Above disclosedly be only a kind of embodiment of the utility model, certainly the interest field of the utility model can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that the utility model claim is done, still belong to the scope that utility model contains.
