With, will heat release infrared signal refraction on PIR：Second, several area pellucidas and dark space will be divided into detecting area, make to enter detection
The heat that the mobile object (people) in area can produce change in the form of temperature change on PIR releases infrared signal.Generally it can also match
Low noise amplifier, when the environment temperature on detector rises, during especially close to normal body temperature (37 DEG C), the spirit of sensor
Sensitivity declines, and gain is compensated via it, increases its sensitivity.Output signal can be used to drive electronic switch, realize LED
The switch control of lighting circuit.
Serious there are waste of energy due to the LED combination of present infrared sensing, sensitivity is low, and inconvenient to use asks
Topic.
Utility model content

In the utility model embodiment, there is provided a kind of LED combination lamps and lanterns based on infrared sensing, by being provided with Fresnel
Filter lens, on PIR thermoelectric elements after the enhancing of Fresnel filter lens, when people is movable, the transmitting position of infra-red radiation will
Change, PIR thermoelectric elements will lose charge balance, and pyroelectric effect occurs and outwards discharges electric charge, PIR thermoelectric elements will
Change through the infrared energy of Fresnel filter lens is converted into electric signal, i.e. heat to electricity conversion.In passive infrared detection
When in the detecting area of device without human motion, simply ambient temperature that infrared inductor senses, when human body is into people's detecting area, passes through
Fresnel Lenses, what pyroelectric infrared sensor sensed is the difference of human body temperature and ambient temperature, signal be collected after with
Already present detection data is compared to judge whether that the infrared sources such as genuine someone enter search coverage in system, if
People, LED light do not work with regard to bright if no one's LED light, and remolding sensitivity is higher, compare saving power supply, more convenient yet.
