Abstract

The utility model relates to a pyroelectric infrared inducing lamp which comprises a lampshade, a base plate and an illuminating lamp. The utility model is characterized in that the lampshade is provided with a through hole. A fresnel lens is arranged in the through hole. Infrared rays which are received by the fresnel lens is aggregated to a pyroelectric infrared sensor by the fresnel lens. The lower end of the fresnel lens is connected with an adjustalbe vertical column with a spring. The pyroelectric infrared sensor is connected with a pyroelectric infrared inducing controller. The utility model can be installed at the places of corridors, passageways and public places to realize the effect that the lamp lights when a person comes, and the lamp is turned off when the person leaves. The static power consumption of the pyroelectric infrared inducing lamp is less than 0.2 W. The inducing distance of the pyroelectric infrared inducing lamp is 8 meters, and the maximum inducing angle of the pyroelectric infrared inducing lamp can be 360 DEG. The utility model has the advantages of simple structure, convenient operation and energy saving.

Description

The pyroelectric infrared-sensing lamp

Technical field

The utility model relates to lighting technical field, particularly a kind of pyroelectric infrared-sensing lamp that uses in corridor, corridor and public place.

Background technology

At present, at corridor, corridor and public illuminating lamp that uses, lamp affixed to the ceiling particularly, its control device generally all adopt hand switch control, and its shortcoming is to cause altar lamp easily, waste energy, also exist in addition and need do long distance wiring and work such as switch is set.

Technical scheme

The purpose of this utility model provides pyroelectric infrared-sensing lamp a kind of simple in structure, easy to use.

The utility model is to realize like this, it comprises lampshade, chassis and illuminating lamp, it is characterized in that on lampshade, opening a through hole, in through hole, be provided with Fresnel Lenses, Fresnel Lenses gathers the infrared ray that receives on the pyroelectric infrared sensor, the lower end of Fresnel Lenses is connected with the adjustable column of band spring, and pyroelectric infrared sensor links to each other with the pyroelectric infrared-sensing controller.

The utility model can be installed in corridor, corridor and place, public place, realizes that the people is bright to lamp, and the people puts out from lamp, and its quiescent dissipation is less than 0.2W, and distance of reaction is 8 meters, and induction angle maximum can reach 360 degree, have simple in structure, the advantage of easy to use and energy savings.

Description of drawings

Below in conjunction with accompanying drawing the utility model is further described,

Fig. 1 is the structural representation of pyroelectric infrared-sensing lamp;

Fig. 2 is the structural representation of lampshade;

Fig. 3 is the circuit diagram of Fig. 1.

The specific embodiment

As Figure 1-3, this pyroelectric infrared-sensing lamp comprises lampshade 1, Fresnel Lenses 2, lining ring 3, sieve cap 4, adjustable column 5, spring 6, pyroelectric infrared-sensing controller 7, chassis 8 and illuminating lamp 9, on lampshade, open a through hole 10, in through hole 10, be provided with Fresnel Lenses, Fresnel Lenses 2 gathers the infrared ray that receives on the pyroelectric infrared sensor PIR, the lower end of Fresnel Lenses 2 is connected with the adjustable column 5 of band spring 6, pyroelectric infrared sensor PIR links to each other with pyroelectric infrared-sensing controller 7, pyroelectric infrared-sensing controller 7 comprises chips W T8072, photo resistance CDS, bidirectional triode thyristor K, resistance R and capacitor C, 9 pin of WT8072 are the optically-controlled signal input, the external RC element decision of 8 pin time-delay, the RC element decision internal clocking frequency of 6 pin is also adjusted resisting of circuit and is done sorrow, 4 pin are reference voltage output end, 1,2,3 pin; 14,15,16 pin are respectively the input and the output of dual-stage amplifier, can change amplifier gain by the resistance R of adjusting 1,3 pin or 14,16 pin, 10,11 pin are the control output end, can control bidirectional triode thyristor K respectively, 13 pin are power positive end, 5 pin are power supply negative terminal, its operation principle is: the infrared ray that the human body that moves sends gathers on the pyroelectric infrared sensor PIR through Fresnel Lenses 2, pyroelectric infrared sensor PIR output just produces a signal of telecommunication, through amplify, light-operated, time-delay and driving, make illuminating lamp light automatically or extinguish automatically.

Claims

1, a kind of pyroelectric infrared-sensing lamp, it comprises lampshade, chassis and illuminating lamp, it is characterized in that on lampshade, opening a through hole, in through hole, be provided with Fresnel Lenses, Fresnel Lenses gathers the infrared ray that receives on the pyroelectric infrared sensor, the lower end of Fresnel Lenses is connected with the adjustable column of band spring, and pyroelectric infrared sensor links to each other with the pyroelectric infrared-sensing controller.
