The touch-type electronic time-delay energy-saving switch disclosed by the utility model is convenient for installation and use, long in service life and obvious in energy-saving effect.
Description
Technical field
The utility model relates to the electronic switch field, relates in particular to a kind of touch type electronic time-delay power down switch.
Background technology
That the electronic delay power down switch mainly is divided into is touch, three kinds of push button harmony touch type electronic standards.
In the prior art, a kind of acoustic control delay switch is arranged, this switch is installed in some corridors or the first-class public place of sub-district road usually, illumination when satisfying our stair activity or walking and the requirement of saving management for infrastructure fee.The principle of this switch be just can conducting under the situation that sound meets certain requirements to light bulb; Promptly when sound decibel number reaches the triggering requirement; Audio-switch will conducting to light bulb; So just can't avoid unintentionally the sounds trigger switch conduction to light bulb, cause waste of electric energy.
In the current techniques, no matter be audio-switch or sonic-opticalcon trolled switch, switch is all connected with bulb, and switch needs faint electric current when work, and this electric current will flow through bulb.This faint electric current can not be lighted incandescent lamp, if but select the present national electricity-saving lamp of recommending, LED lamp etc. for use, because the power of this electricity-saving lamp or LED lamp is less, this faint electric current can make electricity-saving lamp or the flicker of LED lamp or light.Therefore this switching technique is not suitable for electricity-saving lamp or LED lamp.
In the current techniques, also have the main control part of part audio-switch to adopt relay, but relay can receive the influence of factors such as mechanical performance, useful life is shorter, and cost is higher, and noise is bigger, thereby can not get promoting.
The utility model content
The purpose of the utility model is to solve the deficiency that exists in the above background technology, the timing automatic that this touch type electronic delay switch is suitable for stair and the passageway lamp of dormitory building, office building turn off the light control or toilet occasion; The touch type electronic time-delay power down switch that a kind of cost that provides is low and energy-conservation.
For realizing above purpose, the technical scheme that the utility model adopts: a kind of touch type electronic time-delay power down switch, it is characterized in that: it is by DC power supply circuit, delay circuit, integrated being welded on the circuit board of this three partial circuit of control circuit; Described DC power supply circuit is mainly by integrated being welded on the circuit board such as diode rectifier bridge, capacitor, voltage-stabiliser tube and dropping resistors; Described control circuit is mainly by integrated being welded on the circuit board such as NAND gate and bidirectional triode thyristors; Described delay circuit is mainly by charging capacitor and discharge resistance is integrated is welded on the circuit board.
Wherein said controllable silicon should select for use reverse breakdown voltage to be not less than the two-way silicon of 400V, like series such as BCR1AB, 3CTS1A-D.
The beneficial effect of the utility model: the touch type electronic time-delay power down switch of the utility model production has obvious energy-saving effect with respect to traditional switch; Because this touch type electronic time-delay power down switch is by DC power supply circuit, delay circuit, integrated being welded on the circuit board of this three partial circuit of control circuit, degree of integration is high, has obviously reduced production cost; Because this touch type electronic time-delay power down switch is suitable for the timing automatic of stair and the passageway lamp of dormitory building, office building turn off the light control or toilet occasion; Thereby it is applied widely, easy to install and use; The long service life of the utility model.
Description of drawings
Fig. 1 is the utility model circuit theory sketch map.
Embodiment
Below in conjunction with a preferred embodiment and accompanying drawing the utility model is described further, to help understanding the utility model content.
The operation principle of the utility model: the basic principle structure of the energy-conservation delay switch of touch type electronic is made up of DC power supply circuit, delay circuit, this three part of control circuit.
Specifically as shown in Figure 1: as form bridge rectifier by D1-D4, and through dropping resistor R1, LED display lamp D5, capacitor C1 etc., voltage stabilizing to go out the direct voltage of about 4.5V, as the supply power voltage of 555 integrated circuits.This moment, LED lamp D5 was luminous, and switch is convenient to seek night in the indicator cock position.
555 integrated circuits and R4, C2, R3 etc. form a monostable time delay circuit.The terminal sheet metal M of R3 is close to the panel button of lamp switch, and nobody pushes at ordinary times, the non-inductive signal of M, and 555 integrated circuits are in reset mode, and promptly output 3 pin are low level; When people's push switch, the induced signal of human body adds trigger end 2 pin that cause 555 integrated circuits through R3, makes 555 set, and promptly output is transmitted high potential, triggers bidirectional triode thyristor, thereby lamp is lighted, be i.e. time-delay beginning.
The time-delay of 555 integrated circuit monostable circuits, promptly the temporarily steady time of monostable circuit is: t=1.1R4*C2
The temporarily steady time of diagram parameter is about 100 seconds.Regulate the time constant of R4, C2, can change the bright duration of lamp.After 100 seconds, the people leaves, and lamp extinguishes automatically, and energy-conservation economize on electricity is convenient for people to the walking at night again.
More than touch type electronic that the utility model provided time-delay power down switch has been carried out detailed introduction; Used concrete example among this paper the principle and the execution mode of the utility model are set forth, the explanation of above embodiment just is used to help to understand the method and the core concept thereof of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
