Abstract
The invention provides an infrared sensing illumination system, and aims to solve the problem that a traditional illuminating lamp for a community night aisle and courtyard illumination system cannot be automatically controlled to be switched on and off according to human activity information. The infrared sensing illumination system comprises a casing (1) connected with a support ring (2), wherein a group of PIR (pyroelectric infrared sensor) thermoelectric elements (3) are mounted on the support ring; a Fresnel filter lens (4) is mounted at the upper end of the support ring; the center of the Fresnel filter lens coincides with a circle center of the support ring; a circuit element board (5) is fixed at the bottom of the casing and electrically connected with a field effect transistor (6) which is connected with the PIR thermoelectric elements; pins (7) penetrate through the casing to be electrically connected with the circuit element board. The infrared sensing illumination system is used for automatically controlling switching on and off of an LED lamp.
Description
technical field:
the present invention relates to a kind of infrared sensing illuminator.
background technology:
lED illumination lamp and the maximum difference of traditional lighting, LED illumination lamp is an electronic product completely, and traditional lighting is only electric equipment products.Therefore LED lamp can easily with various types of sensors association, thus realize the multiple automatic control functions such as light-operated, infrared control.For aisle at night, community and garden illuminator, traditional illuminating lamp can not accomplish the opening and closing automatically controlling lighting according to Information of Ancient Human Activity, and energy waste is serious.
summary of the invention:
the object of this invention is to provide a kind of infrared sensing illuminator.
above-mentioned object is realized by following technical scheme:
a kind of infrared sensing illuminator, its composition comprises: shell, described shell is connected with support ring, described support ring is provided with one group of PIR thermoelectric element, described support ring upper end is provided with Fresnel filter lens, the center of described Fresnel filter lens and the center of circle of described support ring coincide, described component plate is fixed on described outer casing bottom, described component plate is electrically connected with field-effect transistor, described field-effect transistor is connected with described PIR thermoelectric element, pin is electrically connected with described component plate through described shell.
described infrared sensing illuminator, described PIR thermoelectric element is fixed on described support ring by hot-setting adhesive, and described pin is connected with LED, and described shell is connected with screw socket.
beneficial effect:
1. infrared sensing illuminator works by the infrared ray detecting human-body emitting, the operation principle of this infrared sensing illuminator is as described below: the infrared ray of about 10 μm of human-body emitting gathers pyroelectricity element PIR(passive type infrared thermal releasing electric device after being strengthened by Fresnel filter lens) on detector, when people is movable, the transmitting site of infra-red radiation will change, this element will lose charge balance, there is pyroelectric effect and outwards discharge electric charge, infrared sensing illuminator converts the change of the infrared energy through Fresnel filter lens to the signal of telecommunication, i.e. thermoelectricity conversion.Time in the detecting area of passive infrared detector without human motion, the just ambient temperature that infrared inductor senses, when human body enters people's detecting area, pass through Fresnel Lenses, the difference of what pyroelectric infrared sensor sensed is human body temperature and ambient temperature, already present detection data compares to judge whether really have the infrared sources such as people to enter search coverage after signal is collected and in system.
the present invention has standard screw socket, and its power supply scope of application is AC180V-250V(50/60Hz), infrared sensing illuminator detection range is at 3m ~ 15m, and its standardized product IFS-Bulb3W light fixture reaches 80lm, and 5W light fixture reaches 140lm.Infrared ray sensor is embedded at the middle body of LED light source module.Once infrared sensing illuminator detects the body temperature of people, LED light bulb automatically will open and close in 50s.Be applicable to any one indoor application, as corridor, storeroom, building and grand entrance place.
accompanying drawing illustrates:
accompanying drawing 1 is structural representation of the present invention.
accompanying drawing 2 is circuit theory diagrams of the present invention.
detailed description of the invention:
embodiment 1:
a kind of infrared sensing illuminator, its composition comprises: shell 1, described shell is connected with support ring 2, described support ring is provided with one group of PIR thermoelectric element 3, described support ring upper end is provided with Fresnel filter lens 4, the center of described Fresnel filter lens and the center of circle of described support ring coincide, component plate 5 is fixed on described outer casing bottom, described component plate is electrically connected with field-effect transistor 6, described field-effect transistor is connected with described PIR thermoelectric element, pin 7 is electrically connected with described component plate through described shell.Described shell upper end is transparent glass window 8.
embodiment 2:
infrared sensing illuminator according to embodiment 1, described PIR thermoelectric element is fixed on described support ring by hot-setting adhesive, and described pin is connected with LED, and described shell is connected with screw socket.
embodiment 3:
described infrared sensing illuminator, passive infrared sensing illuminator has three critical elements: Fresnel filter lens, rpyroelectric infrared sensing illuminator and coupling low noise amplifier.Fresnel Lenses has two effects: one is focussing force, infrared signal refraction is released on PIR: two is will be divided into several area pellucidas and dark space in detecting area, and the heat that the mobile object/people entering detecting area can be changed on PIR with the form of variations in temperature releases infrared signal by heat.Generally also can install low noise amplifier in component plate, when the environment temperature on detector rises, time especially close to normal body temperature (37 DEG C), the sensitivity of sensor declines, and compensates, increase its sensitivity via it to gain.
the LED illumination lamp that the present invention controls and the maximum difference of traditional lighting, LED illumination lamp is an electronic product completely, and traditional lighting is only electric equipment products.Therefore LED lamp can easily with various types of sensors association, thus realize the multiple automatic control functions such as light-operated, infrared control.As the automatic switch of LED street lamp, just can simple realization with a light sensor; Aisle at night, community and garden illumination, can gather Information of Ancient Human Activity by infrared sensing illuminator, automatic shutter lighting.
