Description

Electrodelay system of lamplight

The utility model is the improvement to the electronic exciter lamp delayer.

Known light delayer adopts electromagnetic relay more, its complex structure, consumed power are many, volume is big, and even the cost height is some bidirectional triode thyristor delayer, though structure is simplified to some extent, volume reduces to some extent, and cost decreases, if but as the houselights delayer, still seeming, complex structure, volume are big, the cost height.

The purpose of this utility model provide a kind of be used for houselights time-delay but also can be used as the houselights delayer that regular tap uses, simple in structure, that volume is little and cost is low in case of necessity.

Accompanying drawing 1 of the present utility model is the schematic diagram of above-mentioned houselights delayer, the housing of 1 expression delayer, the button on the 2 expression delayer housings.Accompanying drawing 2 is delay circuit figure.

Below houselights delayer of the present utility model is described in detail.

This light delayer is by delayer housing 1, button 2 on the delayer housing, delay switch circuit of electronic exciter lamp in the delayer housing is formed, said delay switch circuit of electronic exciter lamp is formed by connecting by following seven parts: 1. pure resistive lighting load XL, 2. logical live stream is not more than the controllable silicon ST1 of 1 peace, 3. elastic button switch plate S1,4. by diode D1, D2, D3, the bridge rectifier that D4 forms, 5. by push-button switch S1, diode D5, the charging circuit that capacitor C 1 is formed, 6. by push-button switch S1, diode D5, the circuits for triggering that resistance R 2 is formed are 7. by capacitor C 1, the time-delay discharge trigger circuit that resistance R 2 is formed.The anode of above-mentioned controllable silicon ST1 and negative electrode two ends also can the indicator light circuits of being made up of light-emitting diode D6 and resistance R 1 in parallel.In addition: but before the bridge rectifier of delayer parallel manipulator formula contact switch also, if this switch is switched on, then delay circuit is not worked, if switch is disconnected, then delay circuit is activated, as seen if increased this mechanical contact switch on delayer, then delayer can be used as common switch use.

Above-mentioned delay switch circuit of electronic exciter lamp, lay arbitrarily its position in the delayer housing, but elastic button switch plate S1 wherein then designated with the delayer housing on button 2 become light contact elasticity and be connected, make by button 2 to be the work of may command delay circuit.1 outer wall with button 2 of housing becomes sliding connection, in fact, housing role therein mainly is to be used to lay delay circuit and button 2 is relied on thereon, if also include mechanical contact switch in the delay circuit, also can be located at switch on the delayer shell certainly.

The shell 1 of above-mentioned delayer can be designed to have outer casing base and shell cover, and makes base and shell become movable to be connected, so that lay and dismantle the delay circuit in the shell, or the like.Certainly, if necessary, shell also can be designed to a closure casing or other shapes.

Below the delay switch circuit of electronic exciter lamp in the delayer housing is discussed in detail,

1. known electronic delay switch circuit, no matter it is relay system or bidirectional triode thyristor formula, only because of carrying out the components and parts (relay of open and close, bidirectional triode thyristor) difference is equipped with different triggering loops and forms, although the bidirectional triode thyristor formula is advanced to some extent than relay system, their design philosophy all is principle with general.Promptly, only need to carry out in the proper transformation circuit components and parts and suitably adjust the parameter that triggers individual elements in the loop within the specific limits to the circuit of different capacity scope, but circuit operate as normal still, though the circuit widespread usage face that designs like this is comparatively broad.But for some concrete use as being used as domestic lighting light delay switch, volume is big just these circuit seem, cost is too high, and the sense of wasting one's talent on a petty job is arranged.And in fact in people's daily life great majority use little wattage bulb, what particularly be not more than 60 watts of power bulbs accounts for more than 90% of total consumption at least, utility model is exactly at people's bulb used in everyday, the overwhelming majority particularly is not more than this situation of 60W targetedly for little wattage, specific design goes out small-power, and the bulb illumination time-delay is specialized circuit, oversimplify, cost reduces greatly.Volume microminiaturization is so that make delay switch.

2. particularly be not more than the bulb of 60W for little wattage, 1 ampere controllable silicon just can bear its load, because its needed triggering power that is triggered of controllable silicon of 1 peace is very small, so that the energy that the time-delay of low capacity electric capacity discharges, add the ingenious connection of circuit, just can trigger 1 peace controllable silicon.One of major technique means of being taked in the utility model are exactly to utilize resistance R 2, and the loop that capacitor C 1 is formed is the time-delay discharge loop, also are that the controllable silicon time-delay triggers the loop, make circuit greatly simple thereby save a triggering loop.Major technology means the most in Here it is the utility model.It two is that charge and discharge capacitance C1 is connected between the silicon controlled control utmost point and the negative electrode, because controllable silicon is when being triggered conducting, there is pincers to draw the position effect between A point and the negative electrode, filling, the discharge capacity limit is pulled below 1.3V, thereby make the 220V input voltage through D1-D4 and D5 rectification, directly be charged on the capacitor C 1 after the isolation, both can make capacitor C 1 miniaturization, can reduce by a step-down charge circuit again simultaneously, circuit is further simplified, two less important slightly characteristics in addition of utility model are,, one, this invention is provided with the indicator light indication, is indicating not when bulb is lighted, when bulb extinguished, indicator light.Thereby make things convenient for use night, two, the push-button system of this invention is to adopt a tiny soft-touch type microswitch, makes this invention volume more tiny.

The course of work of the circuit of utility model is: when pressing touch switch, the dc pulse electricity that comes out through D1～D4 rectification is triggered to capacitor C 1 charging controllable silicon (bidirectional triode thyristor or one-way SCR) when being charged to certain value through D5, and bulb is luminous.Release button, capacitor C 1 just provides triggering power by resistance R 2 to controllable silicon, make controllable silicon keep conducting (from press button to time that controllable silicon is triggered less than 1/100 second.) controllable silicon ends when the electric capacity both end voltage is reduced to 0.3 volt, bulb extinguishes, so C1 delayed time the time of turning off the light exactly from 1.3 volts of times that drop to 0.3 volt of discharging, the parameter value that changes C1, R2 just can change delay time.The effect of D5 is to guarantee that C1 can be charged near 1.3 volts.D6, R1 constitute pilot lamp loop, and (bulb not) indicator light when controllable silicon triggers, when controllable silicon conducting (bulb) the indicator light D6 that is triggered extinguishes.Because the connecting mode of circuit causes no matter ST is unidirectional controlled or bidirectional triode thyristor, all the positive half cycle of a conducting need add the rectification of D1-D4 bridge, guarantees by bulb it is sinusoidal ac, makes bulb normally luminous.Silicon controlled by principle be when capacitor C 1 discharge into 0.3 volt following and at this moment the major loop dc pulse moving voltage make near zero point by the silicon controlled electric current less than the silicon controlled extinction current, controllable silicon just begins to be turned off.

3. the utility model embodiment, as shown in drawings, if it is that 15W bulb D1, D2, D3, D4, D5 are diode 4004 that each parameter is selected following XY, R1 is that 330K Ω R2 is 150K Ω, and C1 is 220 μ f/10V, and ST1 is that S6370 is 40 seconds when then delaying time, when changing different R2, C1 or ST1, XL just has different delay times, so can cause a series of delay switch.

4. owing to the utility model is particularly to be not more than 60 watts for lighting bulb to design, add the ingenious connection on the circuit, thereby circuit is simplified greatly, manufacturing process is simpler, cost is lower, only have below 1/3 of known delay switch cost, it is very tiny to add upper volume, to promoting the use of the general light switch more known delay switch that gets on widely prospect is arranged.
