Embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
Shown in figure 1 and Fig. 2, an embodiment of the present utility model is a kind of LED based on infrared induction and photosensitive control, comprise LED lamp body, in addition, this LED also comprises infrared induction element 1 and photosensitive switch 2, described photosensitive switch 2 accesses infrared induction element 1, infrared induction element 1 access control chip, described control chip accesses power supply and LED lamp body respectively, the outside of described infrared induction element 1 is also provided with Fresnel Lenses 3, for driving infrared induction element 1 to work on power by photosensitive switch 2, when infrared induction element 1 senses that extraneous IR changes, by the infrared signal transmission that receives to control chip, control LED by control chip to light.
Shown in composition graphs 4, in the embodiment that the utility model is more preferably for technical solution problem, the artificial realization of invention can be extinguished in time after LED is lit under control chip effect, delay switch is set up in the loop of above-mentioned LED lamp body access power supply, has cut off the electricity supply after the unit interval after lighting for LED.Further, lithium battery can be adopted as above-mentioned power supply, and this lithium battery is electrically connected with control chip and LED lamp body by transformer 4.
In the present embodiment, the control mode combined by photosensitive switch 2, infrared induction and delay switch makes LED really achieve the technique effect of " people Lai Dengliang; turn off the light when you leave ", and LED is relative to ordinary incandescent lamp, power is less, and useful life is strong, is comparatively suitable for being arranged on the place without the need to throwing light on for a long time such as corridor, corridor.
Go out as shown in Figure 2, the utility model adopts Fresnel Lenses 3.Fresnel Lenses 3 utilizes the special optical principle of lens, and side produces " blind area " and " highly sensitive district " alternately changed before the detectors, to improve its detection receiving sensitivity.Out-of-date when there being people to walk before lens, the infrared ray that human body sends just constantly alternately enters in " highly sensitive district " from " blind area ", so just makes the infrared signal received input with dynamic impulse form, thus its energy amplitude by force.What infrared induction element 1 adopted is PIR-D203B Thermoelectric Infrared Sensor, and Thermoelectric Infrared Sensor sends signal to process chip after having induction.
Composition graphs 4 and Fig. 5, utility model works principle is as follows:
1) photosensitive switch 2 detects that surround lighting is very dark, and Thermoelectric Infrared Sensor is started working;
2) Thermoelectric Infrared Sensor has sensed people's process, and LED is lighted;
3) LED light while delay control circuit start timing, after 30 seconds, LED is extinguished;
4) if now surround lighting is very dark and still have people to stop or process, the utility model will repeat 2), 3) step.
The utility model center processing chip adopts CSC9803 rpyroelectric infrared control circuit, and CSC9803 is the application-specific integrated circuit (ASIC) for pyroelectric infrared sensor Aided design, utilizes CMOS technology manufacture.Its peripheral components greatly reduces, and has saved space and cost and debug time, has improve the reliability of complete machine.
As mentioned here above, the utility model contains the lithium battery of one piece of 600mAh, when being inserted on socket, is pressed by red switch below the utility model, namely starts to charge to lithium battery, is full of rear automatic stopping charging.When LED infrared induction lamp is not inserted on socket, LED sense light is by containing lithium battery power supply.When switch is turned off, lithium battery neither charges, and does not also discharge.Adding of lithium battery makes the utility model to continue to use 3-4 hour under power failure or case of emergency.
Meanwhile, in above-described embodiment of the present utility model, actual product weight only 84.8 grams, is convenient to the whole modularization of parts, is convenient to artificial or after naturally damaging maintenance.The utility model adopts the input voltage of 220V/50Hz, and female type is installed.Lighting time is more 30 seconds, and the time-division starts to start induction bright light at dusk.Control mode is infrared induction+photosensitive control+delay switch.Lampshade adopts light transmittance to reach the PC section bar lampshade of more than 90%, and irradiating angle can reach 310 degree, conventional light fixture maximum illumination angle only 270 degree, perfect replacement conventional fluorescent radiation response.Contrast with like product, the utility model has the following advantages:
1) adopt highlighted warm white LEDs lamp, brightness is strong, lighting angle is wide, the anti-fatigue of cold light source;
2) high-quality PC section bar, light appears anti-glare lampshade, antistatic process, is not stained with dirt, improves brightness;
3) configure high power factor constant-current supply, stable output, makes the life-span of LED greatly extend, bad light;
4) no color differnece, without stroboscopic and cold light source can effective vision protection, build healthy comfortable environment;
5) energy-conservation, the energy consumption of highlighted warm white LEDs lamp is only 1/10 of incandescent lamp, 1/4 of electricity-saving lamp;
6) long-lived, the life-span of highlighted warm white LEDs can reach more than 50,000 hours, is put things right once and for all for average family illumination.
Than that described above, also it should be noted that spoken of in this manual " embodiment ", " another embodiment ", " embodiment " etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
