Abstract
The utility model relates to an optical-control delay on-off switch, comprising a light-sensitive schmitt circuit, a delay circuit and a controlled silicon triggering circuit. The delay circuit is triggered to delay by the light-sensitive schmitt circuit, and the controlled silicon triggering circuit is driven by the output of the delay circuit. The controlled silicon triggering circuit is used to control the on-off state of the controlled silicon. The optical-control delay on-off switch also comprises an interrupting delay circuit which can interrupt the delay of the delay circuit. The utility model has the advantages of simple circuit, complete function and convenient installation and use.
Description
The utility model relates to electronic switch, particularly light-operated timing closing switch.
Existing various light-operated delay switchs, but these switches can't move the use inconvenience before the time-delay of setting finishes.
The purpose of this utility model provides a kind of light-operated delay switch, and it has the function of interrupting time-delay, can artificially interrupt time-delay in the occasion that does not need normal time-delay, and switch is moved in advance, uses convenient.The utility model has been added the interruption delay function in light-operated delay switch, make light-operated delay switch function more complete, and in addition, circuit of the present utility model is simple, with low cost, and is special because it is connected in series use with power consumption equipment, and it is convenient especially to install and use.
Below referring to Fig. 1 in detail the utility model is described in detail, Fig. 1 is an electrical schematic diagram of the present utility model.
As shown in Figure 1, this optical controlled switch can be divided into four parts: (1) diode D1, D2, voltage-stabiliser tube D3, resistance R 1 and capacitor C 1 consist of the resistance voltage-dropping power supply circuit, for other circuit part provides operating voltage, and (2) photo resistance MG, triode BG4, BG5 etc. consist of photosensitive Schmidt circuit, (3) triode BG1, and resistance R 4, R5 and capacitor C 2 etc. consist of delay circuit, (4) triode BG2, resistance R 2, R3 and capacitor C 3 etc. consist of thyristor gating circuit. BG1 is field-effect transistor. Triode BG4 and BG5 cascade, photo resistance MGConsist of a branch road with resistance R 10, the base stage of BG5 is through resistance and MG, R10 tie point connect, the base stage of triode BG1 is connected to the colelctor electrode of BG4 through a diode; The base stage of triode BG2 is connected to the source electrode of triode BG1 through resistance.
The circuit working principle is as follows.When light is very strong, M
GResistance is very little, and C point current potential is near about 7.0 volts of supply voltage, and BG4 collector electrode output high level charges to C2 by D4, makes the BG1 saturation conduction, and BG2 is saturation conduction also, and a point is a zero level, controllable silicon SCR triggerless electric current and ending.
When the light deepening, C point current potential reduces, the upset of circuit such as photosensitive Shi Mi, and BG4 collector electrode output electronegative potential is because the field-effect transistor input resistance is up to 10
9～10
15The order of magnitude, so grid current is very little, also because of the unidirectional conduction of D4, so the C2 both end voltage can be kept for a long time, this moment, bulb did not still work.After about 0.5～1 hour, the voltage on the C2 descends gradually, makes BG1 also carry out the transition to magnifying state from saturation conduction, and trigger current increases gradually, and the controllable silicon SCR angle of flow increases.BG1 ends when C2 voltage is lower than the BG1 cut-in voltage, and d point current potential is zero, and BG2 ends fully, and the SCR angle of flow reaches maximum, and bulb reaches high-high brightness.When ambient light brightened, lamp extinguished automatically.
Copper sheet M1, resistance R 12, triode BG3 form the time-delay interrupt circuit, and the collector electrode of BG3 is connected to the grid of BG1, grounded emitter, the end of base stage connecting resistance R12.When hand touched M1, the induced signal of human body made BG3 moment conducting by R12, and capacitor C 2 causes BG1, BG2 to end by the BG3 discharge, and the SCR conducting makes lamp bright, has interrupted above-mentioned time-delay.
If connect 1M resistance at a, b point-to-point transmission, because the result of positive feedback, circuit is not to make lamp light gradually but light rapidly after time-delay in 0.5～1 hour.
