Abstract
A nighttime sound control lamp for domestic use is composed of a sound control pulse trigger module, a monostabillity time-delay module, a drive amplifier module and electric lamp. The invention can save electricity and solve the problem of rattled search for lamp switch when emergent accident occur at night.
Description
Technical field
The present invention relates to lighting device, be specially a kind of household acoustic control lamp used at night.
Background technology
Acoustic control lamp is applied to the public arena more, and seldom is used for family expenses, as going to toilet night, when needing illumination, needs to seek light switch, and uses the time of electric light not long during going to toilet, and need finish in two steps, opens and closes light switch, not enough hommization.
Summary of the invention
Technical problem solved by the invention is to provide a kind of household acoustic control lamp used at night, and this acoustic control lamp opens and closes automatically from kinetic energy, and is easy to use.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of household acoustic control lamp used at night comprises an electric light, it is characterized in that, described lighting circuit connects one and drives amplification module, and described driving amplification module circuit connects a monostable time delay module, and described monostable time delay modular circuit connects an acoustic control pulse-triggered module.
Operation principle of the present invention is as follows: the sound signal that transmits in the acoustic control pulse-triggered module contact environment, acoustic control this moment pulse-triggered module produces a trigger current, and trigger current passed to the monostable time delay module, the monostable time delay module prolongs current signal, and send the driving amplification module to, the driving amplification module amplifies electric current and passes to electric light, and electric light is shinny.
Beneficial effect: the electrical energy saving of the present invention's energy can solve people will seek lamp switch earlier in flurried when tackling emergency case night trouble.
Description of drawings
Fig. 1 is a circuit diagram of the present invention;
Fig. 2 is a circuit composition frame chart of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1 and Figure 2, a kind of household acoustic control lamp used at night is made up of an acoustic control pulsed triggering circuit, monostable time delay circuit, driving amplifying circuit and an electric light four parts.The acoustic control pulsed triggering circuit is made up of piezoelectric ceramic piece B, transistor VT1, resistor R 1 and R2.The acoustic control pulsed triggering circuit is accepted acoustic signals, and is converted into corresponding ultra-weak electronic signal to trigger the effect that entire circuit starts; The monostable time delay circuit works the time lengthening that makes lamp bright; Driving amplifying circuit plays amplification signal to make bulb reach rated voltage luminous.Household acoustic control lamp used at night is at ordinary times by 3 joint 1.5v powered battery.During use, only need the closed mains switch SA of user, circuit enters energising and treats operating state.At this moment, the biasing resistor R1 resistance of transistor VT1 is bigger, VT1 is in incomplete conducting state (being tending towards cut-off state), time-base integrated circuit A electronegative potential trigger end the 2nd pin that is attached thereto is in high level, monostable circuit is in stable state, and the 7th, 1 pin of A is passed through by the triode short circuit of the inner conducting of A, the 3rd pin output low level of A in capacitor C two ends, VT2, VT3 all do not have bias current and end, and lamp H is not luminous.
When piezoelectric ceramic piece B receives acoustic signals, be converted into corresponding ultra-weak electronic signal.The positive half cycle of this signal is after transistor VT1 amplifies, from its collector electrode output negative pulse signal of telecommunication, the 2nd pin of time-base integrated circuit A promptly obtains the low level triggering signal that moment is lower than 1/3VDD=1.5V, the monostable circuit that A is formed is subjected to trigger and enters temporary stable state (state of promptly delaying time), the 3rd pin output high level signal of A, VT2 obtains suitable bias current conducting, and VT3 enters complete saturation conduction state, and light is sent in lampet H energising.
Along with the 3rd pin of A becomes high level, the triode of the inner conducting of A ends, and has removed the short circuit to capacitor C, and battery G promptly begins charging by resistance R 3 to capacitor C.When C two ends charging voltage (being high potential trigger end the 6th pin current potential of A) when reaching 2/3VDD=3V, stable state is replied in the monostable circuit upset, the conducting again of the inner triode of A, C is by the 7th, the 1 pin discharge of A and by short circuit once more, the 3rd pin of A is output low level again, cause transistor VT2, VT3 to lose bias current and end, lampet H outage is extinguished automatically.
If the user handles thing and finishes and will turn off the light in advance, can the 3rd pin output high level, the H of A luminous during, press reset button switch S B, then forced resetting end the 4th pin of A will ground connection, monostable circuit promptly is forced to reset, the 3rd pin output low level of A, and H extinguishes immediately.
