Description
Technical field
The utility model relates to field of light fittings, more particularly, and the particularly intelligent light-controlled night-light of one.
Background technology
In indoor, people generally use the light fixtures such as desk lamp, desk lamp and wall lamp, and to save electric energy, existing ordinary lamp and lantern only has king light and governor circuit usually, the light on and off of king light are the switch control rule by governor circuit, the bright dark degree controlling king light by slide switch also had.
Light-operated night-light of the prior art is mainly realized by photo resistance, and the resistance namely by changing photo resistance controls the Kai Heguan of night-light, and in dark conditions, the resistance of photo resistance is very high; When being subject to illumination and optical radiation energy is enough large, electronics in light-guide material forbidden band is subject to the photon excitation that energy is greater than its energy gap Δ Eg, cross forbidden band by valence band and transit to conduction band, the electronics of its conduction band and the hole of valence band are increased, and resistivity diminishes; Thus the function that realization is opened and closed.
But light-operated night-light of the prior art also has problems: that is, when light fixture in the dark time it is in darker state; But when people have matter of urgency to need to process, this light fixture can not be lighted at once.Therefore, be necessary to improve existing light-operated night-light.
Utility model content
The purpose of this utility model is to provide a kind of intelligent light-controlled night-light in case of emergency can lighted rapidly.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of intelligent light-controlled night-light, comprise connect successively power supply, photo resistance, main circuit and light fixture, the on-off circuit in parallel with photo resistance, and be connected with on-off circuit and for the sound detection circuit of gauge tap circuit turn-on or closedown.
Preferably, described on-off circuit comprises relay and triode, the main contact parallel of described relay is at the two ends of photo resistance, main coil one end of described relay is connected with+12V power supply, the other end is connected with the colelctor electrode of triode, the grounded emitter of described triode, its base stage is connected with sound detection circuit.
Preferably, described sound detection circuit comprises interconnective sound transducer and A/D converter, and the output of described A/D converter is also connected with the base stage of triode.
Compared with prior art, the utility model has the advantage of: the utility model adopts photo resistance to control light fixture on the one hand, the dark bright degree of light fixture can be controlled according to different environment, save electric energy, the size that another aspect detects sound by sound detection circuit comes gauge tap circuit turn-on or closedown, when sound is larger (by sending larger sound during emergency), on-off circuit conducting, power supply is directly connected with main circuit, and then light light fixture, when voiceless sound, on-off circuit cuts out, normal employing photo resistance controls light fixture.

Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection domain of the present utility model.
Consult shown in Fig. 1, the utility model provides a kind of intelligent light-controlled night-light, comprise connect successively power supply 1, photo resistance 2, main circuit 3 and light fixture 4, the on-off circuit in parallel with photo resistance 2, and be connected with on-off circuit and for the sound detection circuit of gauge tap circuit turn-on or closedown.
In the utility model, described on-off circuit comprises relay 5 and triode 6, the main contact parallel of described relay 5 is at the two ends of photo resistance 2, main coil one end of described relay 5 is connected with+12V power supply, the other end is connected with the colelctor electrode of triode 6, the grounded emitter of described triode 6, its base stage is connected with sound detection circuit.
In the utility model, described sound detection circuit comprises interconnective sound transducer 8 and A/D converter 7, and the output of described A/D converter 7 is also connected with the base stage of triode 6.When sound transducer 8 detects voice signal, transmit signals in A/D converter 7 and carry out analog-to-digital conversion, then export the base stage of triode 6 to.
Concrete, the principle of described sound detection circuit gauge tap circuit is: when voice signal is large, A/D converter 7 continues to export the base stage of high level signal to triode 6, now triode 6 conducting, relay 5 closes, power supply 1 walk around photo resistance 2 directly with main circuit 3, and then rapid conducting light fixture 4; And when voice signal is less, A/D converter 7 continues the base stage of output low level signal to triode 6, and now triode 6 turns off, and relay 5 disconnects, power supply 1 needs to be connected with main circuit 3 by photo resistance 2, namely needs to control light fixture 4 according to bright environment.
The operation principle of intelligent light-controlled night-light of the present utility model is: adopt photo resistance 2 to control light fixture 4, can control the dark bright degree of light fixture according to different environment, in dark conditions, the resistance of photo resistance is very high; When being subject to illumination and optical radiation energy is enough large, electronics in light-guide material forbidden band is subject to the photon excitation that energy is greater than its energy gap Δ Eg, cross forbidden band by valence band and transit to conduction band, the electronics of its conduction band and the hole of valence band are increased, and resistivity diminishes; Thus the function that realization is opened and closed, save electric energy; Simultaneously, the size that the utility model also detects sound by sound detection circuit comes gauge tap circuit turn-on or closedown, when sound is larger (by sending larger sound during emergency), on-off circuit conducting, power supply is directly connected with main circuit, and then light light fixture, when voiceless sound, on-off circuit cuts out, and normal employing photo resistance controls light fixture.
Although describe embodiment of the present utility model by reference to the accompanying drawings; but patent owner can make various distortion or amendment within the scope of the appended claims; as long as be no more than the protection domain described by claim of the present utility model, all should within protection domain of the present utility model.
