The timing switching-off control device is composed of a rectifying filter circuit, a delay switch circuit and a triggering switch circuit. The utility model can be widely used in public places such as dwelling houses, public housings, office buildings, the corridors of hotels, passageways, etc. to achieve the purposes of illumination, the timing closure of electric lamps and power saving.
Description
The utility model relates to a kind of lamp holder with the timing shutoff device.
The on and off that are installed in the electric light of public place (as the corridor in public housing) at present are opening and closing and realize by the switch in the circuit.The on and off that realize electric light by the one group of switch that is located at different floors are also arranged, the installation complex circuit of this method, switch doubles, and the on and off of electric light also will be moved corresponding switch at different floors by the user and be realized, and are very inconvenient.
The purpose of this utility model is to provide a kind of easy to use, and the energy timing automatic is closed the lamp holder of the band timing shutoff device of electric light, and it can replace traditional lamp holder to be installed in the public place use.
The purpose of this utility model is achieved in that the lamp holder of band timing shutoff device comprises body, bulb socket and bulb inlet wire terminals, it is characterized in that also being provided with in the bulb socket regularly shutoff control unit, also be provided with control button terminals and electric power incoming line terminals in the bottom of bulb socket, regularly shutoff control unit is by current rectifying and wave filtering circuit, and delay switch circuit and trigger switch circuit are formed.
The utility model is simple in structure, cost is low, regularly shutoff device can be directly installed in the bulb socket of traditional straight type lamp holder and oblique type lamp holder, the installation method of the lamp holder of band timing shutoff device is also identical with conventional method, only needs to push the button during use, and electric light will brighten, when arriving time of delay, electric light just extinguishes automatically, and both convenient the use saved electricity consumption again.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the electrical schematic diagram of timing shutoff control unit of the present utility model.
Describe CONSTRUCTED SPECIFICATION of the present utility model and working condition in detail below in conjunction with accompanying drawing.
The utility model comprises lamp water body 1 and bulb socket 6, and the bottom of body 1 is provided with bulb inlet wire terminals 2, and the bottom of bulb socket 6 is provided with regularly shutoff control unit 3, and the terminals 5 and the electric power incoming line that also are provided with control button AN in the bottom of bulb socket 6 connect end 4.Regularly shutoff control unit 3 is by current rectifying and wave filtering circuit, and delay switch circuit and trigger switch circuit are formed.Described current rectifying and wave filtering circuit is by diode D1, and resistance R 1 and capacitor C 1 are formed, and the negative terminal of diode D1 links to each other with an end of resistance R 1, and the other end of R1 links to each other with capacitor C, the other end ground connection of C1; Described delay switch circuit is by resistance R 2, R3, R4, capacitor C 2, voltage stabilizing didoe DW and triode BG form, the end of resistance R 2, R3 and R1 links to each other, resistance R 2 other ends link to each other with an end of capacitor C 2, the base stage of triode BG, and the end of resistance R 3 and R4 links to each other with the collector electrode of triode BG, and the other end of resistance R 4 links to each other with the emitter of triode BG, and link to each other the positive ending grounding of voltage stabilizing didoe DW with the negative terminal of voltage stabilizing didoe DW again; Described trigger switch circuit is by two-way trigger tube D2, capacitor C 3, resistance R 5 and bidirectional triode thyristor SCR form, the end of two-way trigger tube D2 and capacitor C 3, resistance R 4 links to each other, and the other end of two-way trigger tube D2 links to each other with the control utmost point of bidirectional triode thyristor SCR and the end of R5, the end ground connection of bidirectional triode thyristor SCR, other end D links to each other with bulb inlet wire terminals 2 one ends, and the other end of resistance R 5 links to each other with the anode of diode D1 and the other end of bulb end of incoming cables 2; Two terminals 5 of described control button AN are drawn from two end a, the b of capacitor C 2 respectively.Control button AN is installed in the user desired position, two lead-out wires of control button AN are received control button terminals 5, electric power incoming line terminals 4 link to each other with C, E in the timing shutoff control unit 3 respectively, 220 volts of alternating currents are directly received electric power incoming line terminals 4, and electric light is installed in the body 1.After the user pressed button AN, capacitor C 2 discharges made the base stage above earth potential vanishing of triode BG, and triode BG ends, and its collector potential raises, and makes two-way trigger tube D2 conducting, and also conducting of bidirectional triode thyristor SCR is at this moment lighted electric light W; After the user bleeds off control button AN, power supply is by diode D1, resistance R 1, R2 are to capacitor C 2 chargings, when the magnitude of voltage of capacitor C 2 reaches voltage stabilizing value (about 9.5 volts) greater than voltage-stabiliser tube DW, triode BG conducting, the BG collector potential descends, when dropping to the conducting voltage that is lower than two-way trigger tube D2, bidirectional triode thyristor SCR ends, and at this moment electric light W just extinguishes.The charging interval of capacitor C 2 is the bright delay time of electric light W, its time length depends primarily on the numerical value of resistance R 2 and capacitor C 2, R2 is 2.7M Ω (or 2.4M Ω) in this example, C2 is 100 μ F, and the bright time of electric light W is about 90 ± 15 seconds, because the power consumption of timing shutoff control unit 3 is less than 0.1 watt, so do not influence the brightness of electric light, only realized just reaching illumination by a button, and the purpose extinguished automatically of electric light.According to the above course of work, can also be with the regularly lamp holder of shutoff device with one, draw two leads from its bulb inlet wire terminals 2, some electric lights (but gross power is less than 75 watts) respectively in parallel more just can realize that a control button AN controls the purpose of many electric lights; Also can realize the purpose of an electric light of a plurality of control button controls by the method for many control buttons in parallel at control button AN terminals 5 places.
In the former place that the conventional lights head is housed, can separately timing shutoff control unit 3 of the present utility model be installed in the capsule, method of attachment according to Fig. 2 is connected on the lamp holder, replaces original switch with button, can realize regularly closing the effect of electric light equally.
The utility model can be widely used in public places such as the corridor, corridor in dwelling house public housing, office, hotel, reaches the purpose that electricity consumption was regularly closed and saved to illumination, electric light.
