Description
The utility model relates to electronic switching technology, is specially the light-controlled electronic switching technique, and international Patent classificating number intends being HO5B37/00 and H03K 17/00.
Illumination, it is bright that particularly public lighting Ying Ri puts out night, with saves energy, now generally uses labor management, very uneconomical.People attempt to change this state, utilize certain day to put out bright switching technique at night automatically, and are artificial to replace, and reach the economic purpose of economize on electricity.But it is as if not ideal.Problem mainly is Changes in weather (as dark clouds sleet), jamming light source, (thunderous, electric, veiling glare) and critical flicker.Reported a kind of " solar energy self-control road lamp switch " utilization " solar cell is powered to an electric-controlled switch " for No. 94202282 as Chinese patent, " sun has electric current to flow through when sufficient " is with the break-make of control switch.Obviously, the cloudy day rains, and cloudy have a mist, and normal weather phenomenon such as the snowfall of blowing all might make this switch produce misoperation, does not reach the purpose of asking; " stray light and non-stray light (natural daylight) " discerned in and for example a kind of " anti-interference light-operated power down switch " utilization of No. 90223697, Chinese patent report light-sensitive element and the guider or the light spacer of two above different directions or diverse location " three or ".This technology still adopts conventional light-operated switch, itself there is no improvement switch, just increased the identifier of stray light and non-stray light, but the light-sensitive element of this identifier-technologies is many, the installation site is very key again, whether " direction " and " position " of design has adapted to the sunlight of several irregular jamming light source and week day operation, doubtful.A kind of " simulating time-control switching unit the sunshine of intelligence " of No. 94235873 reports of Chinese patent for another example, the keying that utilizes " function of perpetual calendar is to realize simulating of counterglow " to come control switch.Though this technology has been kept away the complexity (as critical flicker etc.) of natural daylight control, can not be subjected to the influence of stray light, its versatility is bad.Because sunshine, situation very all can influence sunshine in complexity, longitude, latitude, Plain, mountain area etc., single software " simulates " and gets up very difficultly, use to adjust also non-easy thing, if various software more complicates the issue, it is unfavorable to promote; On the other hand this specification requirement computer arranged, simulate software, the general all no components and parts of light-operated switch such as UPS uninterrupted power supply, clock, keyboard, cost is high, the operative employee uses, the equal difficulty of maintenance, promotes the use of unfavorablely also to be difficult for.
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, with low cost, strong interference immunity, and no critical flicker, light-operated some adjustable range is big, the electronic switch of the natural daylight control of contactless control.
The purpose of this utility model is realized by following technology: a kind of electronic switch of natural daylight control, comprise panel 7, bonnet 9 and wiring board 8, it is characterized in that the circuit connection on the wiring board 8 is followed successively by power circuit 1, photoelectric switching circuit 2, antihunt circuit 3, comparison circuit 4, shaping circuit 5 and executive circuit 6; Described power circuit 1 is a capacitance decompression halfwave rectifier power circuit 1; Photoelectric switching circuit 2 is regulated resistance R by photodiode 2CU and light-operated point
wBe composed in series; Antihunt circuit is by resistance R
2And capacitor C
3Form resistance R
2One end links to each other with the negative pole of photodiode 2CU, and the other end inserts triode T in the comparison circuit 4
1Base stage, comparison circuit 4 is by triode T
1, T
2The multiple tube emitter output circuit of forming, triode T
2Emitter-base bandgap grading insert triode T in the shaping circuit 5
3Base stage; Shaping circuit 5 is by triode T
3, T
4The flip-flop circuit of forming 5, and by triode T
4Collector electrode insert diode D in the executive circuit 6
3Positive pole, executive circuit 6 be by triode T
5, T
6The multiple tube collector plate power supply of forming can be sent out the output circuit 6 of bidirectional triode thyristor BCR; Meet load L between the first anode of bidirectional triode thyristor BCR and the N of the power supply end, the second plate of bidirectional triode thyristor BCR connects the L end of power supply.
By technical solutions of the utility model as can be seen, it has only used the most frequently used electronic devices and components such as a spot of electric capacity, resistance, two, triode, obviously has the feature of (even only have some prior art scheme hundreds of times/) simple in structure, with low cost; Design simple antihunt circuit, utilized the delay of capacitor charge and discharge performance, can effectively realize the strong characteristics of anti-veiling glare interference; Designed emitter-base bandgap grading coupling bistable state shaping circuit, can accelerate the upset of state, thereby avoid critical flicker; Adjust light-operated some adjusting resistance R in the simple photoelectric switching circuit
wResistance, can realize light-operated bigger adjustable range, to be suitable for the needs of different situations; Natural daylight is as the control light source, and photodiode 2CU can realize the contactless control of electronic switch as photo-electric conversion element.
Experiment shows that light-operated some adjustable range of the present utility model can be from very black to very bright, and adjusts easyly, is suitable for the requirement of different weather and season and different condition; Threshold variations flicker free phenomenon, the utility model switch and being failure to actuate under continuous 10 seconds strong illumination, be enough to avoid veiling glares such as car light, flash of light, thunder and lightning to disturb, being applicable to variously needs daytime and puts out bright public lighting occasion at night, locates as unattended automatic switch as street lamp, navigation light, neon light, advertising lamp, decorative lamp plant area, warehouse, square etc.
Below in conjunction with embodiment and accompanying drawing thereof in detail the utility model is described in detail:
Fig. 1 is that circuit of the present utility model is formed schematic diagram;
Fig. 2 is a line principle schematic diagram of the present utility model;
Fig. 3 is a surface structure schematic diagram of the present utility model;
That power circuit 1 of the present utility model adopts is capacitor step-down half-wave rectifying circuit 1 (referring to Fig. 1), and specific design is: capacitor C
1And resistance R
1After, a termination exchanges the N end of 220 volts of power supplys, and the negative terminal of another termination voltage-stabiliser tube 2CW, the anode of voltage-stabiliser tube 2CW then connect the L end of power supply; Connect the anode of diode D by the negative terminal of voltage-stabiliser tube 2CW, connect capacitor C again
2Anode after, the L in telegram in reply source end.Exchange 220 volts, through capacitor C
1Step-down, after the voltage stabilizing of voltage-stabiliser tube 2CW amplitude limit, output voltage is stored in capacitor C
2In, capacitor C
2Both end voltage be output DC source voltage, design parameter is a 7-15 volt.This direct voltage is used for each follow-up circuit, and has played the governor circuit buffer action as control voltage, in order to avoid element decreases part.
In sum, the utility model entire circuit course of work can followingly be represented (e, b, c represent emitter-base bandgap grading, base stage, the collector electrode of triode Ti respectively, and i then shows the sequence number of triode): when natural light brightness weakens and is lower than light-operated of setting,
, T
2Conducting → T
