Abstract
The utility model relates to a delayed lighting switch for controlling lighting fixtures. The utility model is composed of a connecting key on a panel, a base, and a control circuit. The control circuit is composed of a full-wave rectification bridge, a silicon controlled rectifier, a capacitor, a resistor, and a switch. The control electrodes of the silicon controlled rectifier is connected with the switch and the capacitor via the resistor, the negative electrode and the positive electrode of the silicon controlled rectifier are respectively connected with the two output endd of the full-wave rectification bridge, the control electrode and the other end of the capacitor are connected with a common end, and an electrical lamp is installed at the input end of the full-wave rectification bridge. The utility model has the advantages of simple structure, convenient operation and long service life. The generalization and application prospect of the utility model is good.
Description
Lighting switch is put out in prolonging that the utility model relates to use in a kind of daily life.
Switch is the control lighting, as bulb, fluorescent lamps etc. leave and close requisite, and the bulb switch of usefulness is mechanical key switch and pulling switch at present, all be to be contained on the wall, its structure is by panel, base and button, binding post constitutes, the switch of this version, after switch disconnects, lighting extinguishes at once thereupon, and the people need withdraw from a room in the dark or go to bed and go to bed, and feels very inconvenient, and the Kai Heguan of this structure, life-span to lighting makes a strong impact, because of mechanical open and close light fixture extinguished and light, its transient current is very big, easily burn bulb or fluorescent tube, burning out of many bulbs all is to close, take place when turning on light, in case light fixture burns out, more life brings not side.
The purpose of this utility model provides a kind ofly novel opened and closes prolonging of usefulness for the control light fixture and put out lighting switch.
The purpose of this utility model is achieved like this, existing mechanical switch is structurally transformed, promptly adorn one and prolong and put out circuit on two binding posts of mechanical switch, light fixture connects and prolongs the output that puts out circuit, prolongs to put out circuit and be made of full-wave rectification bridge and controllable silicon and resistance capacitance.
Its novel structure of the utility model, easy to use, light fixture such as bulb, fluorescent tube long service life, application prospect light.
Below in conjunction with accompanying drawing structure of the present utility model is elaborated.The accompanying drawing example is a wall type structure.
Fig. 1 is the front view of the utility model structure.
Fig. 2 is a lateral plan of the present utility model.
Fig. 3 is a rearview of the present utility model.
Fig. 4 is control circuit figure of the present utility model.
Shown in Fig. 1-3, its structure of the utility model is, be equipped with switch key 2 in the middle of the panel 1, there is fixing hole 3 on button 2 both sides, base 4 is equipped with in panel 1 back, circuit board 5 is housed on the base 4, binding post 6 is arranged on the circuit board 5 and prolong and put out control circuit, and is furnished with circuit board fixed screw 7, said prolonging put out control circuit and forms full-wave rectification bridge by diode D1-D4, and the control utmost point of controllable silicon SCR connects K switch and capacitor C through resistance R, and the negative electrode of one-way SCR and anode connect two outputs of full-wave rectification bridge respectively, the termination common port (ground wire) in addition of the control utmost point and capacitor C, electric light H is contained on the input of full-wave rectification bridge.
Exemplary of circuit shown in Figure 4 is, diode D1-D5 is the IN4007 type, and controllable silicon SCR is 1A/400V, and resistance R is 200K, and capacitor C is 220 μ f/25V.
Working condition of the present utility model is, K switch closure when turning on light, and the unidirectional controlled SCR conducting that is triggered, bulb H lights, and for illumination, simultaneously, alternating current is after the full-wave rectification bridge rectification that diode D1-D4 constitutes, by diode D5 with open and produce K and charge to capacitor C; When turning off the light, K switch disconnects, and the power supply on the capacitor C continues to push away to unidirectional controllable silicon S CR through resistance R holds conducting, and electric light H continues bright.After after a while (delay time), the discharging current on the capacitor C is less than the trigger current of unidirectional controllable silicon S CR, and when the alternating current zero passage, controllable silicon turn-offs, and electric light H is cut off, and electric light extinguishes, the not power consumption of time-delay stage circuit itself.As change the value of resistance R or capacitor C, just can change electric light prolong the time of putting out, the utility model can be used for pulling switch, switch on wall or push switch etc., the visual different situations of user are selected for use.
The utlity model has following characteristics:
(1) this switch is the same with regular tap, only has two terminals, and does not have the branch of fire, zero line, Easy to install and use, need not change original wiring method, can exchange with existing switch.
(2) this switch is behind lights, and its off-state resistance is infinitely great, and itself no longer consumes electricity Can, can regard it like a passive device as.
(3) time of putting out that prolongs of this switch can be produced 10 seconds-5 minutes differences according to user's needs Prolong the switch of the time of putting out, and can control the multiple lamp tool, solved present some electronic switch and used The shortcoming that property is single.
(4) produce that this switching technique is simple, cost is low, and avoid using transformer and relay.Under the situation that does not change existing machinery formula switch external form, structure, install time delay device additional and get final product.
Claims (2)
1, a kind of prolonging put out lighting switch, be in the middle of panel (1), to be equipped with switch key (2), there is fixing hole (3) on the button both sides, base (4) is equipped with in panel (1) back, it is characterized in that being equipped with on the base (4) circuit board (5), binding post (6) is housed on the circuit board (5) and prolongs and put out control circuit, said prolonging put out control circuit and forms full-wave rectification bridge by diode D1--D4, the control utmost point of controllable silicon SCR connects K switch and capacitor C through resistance R, the negative electrode of one-way SCR and anode connect two outputs of full-wave rectification bridge respectively, the termination common port in addition of the control utmost point and capacitor C, electric light H is contained in the input of full-wave rectification.
2, according to claim 1 prolonging put out lighting switch, it is characterized in that said resistance R and capacitor C are variable.
