The utility model brings convenience to life, and saves electric energy.

Description

Electricity-saving lighting installation

The utility model relates to a kind of economize on electricity lighting device.

In daily life, people often need feel about in the dark at night and turn on electric light, cause altar lamp because of forgetting to turn off the light sometimes after lamp is opened, and this common illuminating lamp uses not only inconvenience but also takes.

In order to change this situation, people have designed many battery saving arrangements, and common measure is to insert a delay switch that is subjected to artificial control between power supply and lamp, are turned on light by triggering such as people's clapping or whistle, extinguish automatically after the delay of certain hour.The shortcoming of this class device is: still must artificially control, even and turn on light people from back also do not leave, after the delay of certain hour, also to extinguish automatically, in use cause new trouble on the contrary.

The utility model is to launch the ultrasonic wave signal with a kind of ultrasonic device, when arriving, the people causes hyperacoustic Doppler effect, control the Push And Release of illuminating lamp by reception and testing circuit, lamp is bright when reaching the someone and arrive with this, the effect of just extinguishing after the people walks, so not only make people feel convenient and comfortable, improved the quality of life, and power savings also is best.

Because the consistency of ultrasonic device performance parameter is relatively poor, in use, will make the control range of product inconsistent as not solving, qualification rate reduces.

The purpose of this utility model is the inconsistent problem of performance parameter that solves ultrasonic device, designs a kind of economize on electricity lighting device that is suitable for suitability for industrialized production.

The utility model has been realized above-mentioned purpose by following technical measures: it is made of lower pressure rectifier circuit, oscillation drive circuit, emission ultrasonic transducer, reception ultrasonic transducer, amplifying circuit (1), detecting circuit, automatic gain control circuit, amplifying circuit (2), monostable trigger-action circuit, light-operated circuit, relay, cabinet and illuminating lamp.It is characterized in that: 1, inductive element is arranged in oscillation drive circuit, the oscillating voltage that drives the emission ultrasonic transducer is improved, come the relatively poor transducer of indivedual performance parameters is compensated to increase transmitting power.2, in detecting circuit and amplifying circuit, automatic gain control circuit is arranged, to suppress the too high performance parameter of individual transducers.Its operation principle is: the supersonic oscillations voltage of the oscillation drive circuit output crest voltage of inductive element greater than the oscillation drive circuit direct-current working volts is arranged, drive the emission ultrasonic transducer and launch the ultrasonic wave signal, fixing arriving with the various reflected by objects that move in diffraction and Be Controlled scope receives ultrasonic transducer, convert the signal of telecommunication to after amplifying circuit amplifies, again through the detecting circuit detection, the Doppler signal that detects direct voltage and produce by the mobile object reflection, direct voltage is tending towards constant after automatic gain control circuit control; Doppler signal triggers monostable trigger-action circuit again and drives relay connection lighting lamp power after amplifying, wherein monostable trigger-action circuit is quit work by again the daytime that is controlled at of light-operated circuit.

Below by accompanying drawing the utility model is further specified:

Fig. 2 electrical schematic diagram

Fig. 3 stereogram

In Fig. 2, the lower pressure rectifier circuit of being made up of B1, D5-8, C11, IC5 becomes alternating current 220V into direct voltage, through the stable complete machine operating voltage of 3 pin output of circuit of three-terminal voltage-stabilizing integrated IC5.

Form oscillation drive circuit, output ultrasonic wave oscillating voltage by IC4, C10, R10, D4, L1, drive emission ultrasonic transducer T40 emission ultrasonic signal, because the induced potential of L11, make the oscillating voltage peak value that drives T40 be higher than the direct voltage of supplying with oscillation drive circuit, come the relatively poor transducer of indivedual performance parameters is compensated with the transmitting power that increases T40.

Being received ultrasonic transducer R40 after the various objects fixing and that move of T40 ultrasonic waves transmitted signal in diffraction and Be Controlled scope reflect receives, after converting electric signal to, arrive by IC1 through C1, R1, C2, the amplifying circuit (1) that R4 forms amplifies, amplify after C3 arrives by D1, D2, the detecting circuit that C4 forms carries out detection, the Doppler signal that after detection, obtains a direct voltage and produce by the mobile object reflection, this direct voltage is via R2, R3, C5, the control of the automatic gain control circuit that Q1 forms and be tending towards constant suppresses the too high transducer of indivedual performance parameters with this; Doppler signal amplifies to the amplifying circuit of being made up of IC2, R5, R6, C7, C8, D3, Q2 (2) through C6, triggers the monostable trigger-action circuit of being made up of IC3, R7, C9, drives the power supply that relay J is connected illuminating lamp W.4 pin of IC3 are subjected to the light-operated circuit control of R8 and photo resistance R9 composition again in the monostable trigger-action circuit, and monostable trigger-action circuit is quit work by day.

Among Fig. 3,1 is casing, emission ultrasonic transducer 2 is arranged on the panel and receive ultrasonic transducer 3,4 to be photo resistance, and 5 is indicator light.The input and the civil power 220V of economize on electricity lighting device join, output termination illuminating lamp.

Be not difficult to find out that from above narration the utility model is actually the economize on electricity lighting device that the principle of utilization radar and sonar is controlled, its function is novel unique, and simple for structure, with low cost.Its suitable a lot of occasion such as entrance hall, passageway, corridor, stair, public lavatory that are installed in.The people turns on light automatically, turns off the light automatically again after the people walks, and both having avoided feels about in the dark changes the trouble of pass, has avoided the waste that forgetting turns off the light causes again.With driveing with the pass, the automation of height and novelty were brought both can for people's life and greatly facilitated and enjoyment, obtained best power savings again.Therefore, the utility model will be to be subjected to the novel power saving lighting device that people like.
