Description

Automatic delay lamp switch controlled by sound and light

The utility model belongs to lamp switch, particularly the automatic time delay lamp switch of voice signal and surround lighting control.

Present corridor, corridor and other public place, generally the luminous lamp switch of An Zhuaning mainly contains two kinds, and a kind of is single connection plane switch, promptly by lamp of a switch control.The position that this switch is installed can only be fixed on the top or the bottom of a place such as corridor, corridor a certain first-class, and need people's action could work, use is inconvenience extremely.Another kind is a ganged switch, promptly removes to control a lamp by two single-pole double-throw switch (SPDT)s by the connection of circuit.This switch generally is installed in the upper and lower position of corridor, or the two in corridor, and the action of arbitrary switch can both use controlled lamp to open or close.The result of use of this switch is better, and shortcoming is that complexity of circuit is installed, and simultaneously, this switch still needs people's action to work, and uses still inconvenient.Owing to these reasons, the public place uses the illuminating lamp of this class switch often to be in state all night kept burning day and night, has both wasted electric energy, and the life-span of bulb is shortened greatly, and therefore, the structure of this class switch and control mode need be improved.

Task of the present utility model is, improves the structure and the working method of this class switch, makes novel switched state that can automatic control lamp, reaches conveniently and installs and uses, the purpose of avoiding waste of energy and prolonging bulb life.

Structure and working method that the acousto-optic control automatic time delay lamp switch that claim 1 proposed is possessed have been finished this task.

A kind of acousto-optic control automatic time delay lamp switch is characterized in that shell makes with insulating material such as phenolic resins, in adorn a circuit board.Two holes are arranged on the shell, be used for installing the element that receives voice signal and ambient light signal.Lead is drawn at the shell two ends, a termination AC power, the controlled lamp of another termination.Circuit board is made up of voice signal receiving circuit, surround lighting receiving circuit, triggering delay control circuit, thyristor switch and several parts of power supply step-down rectifying circuit.Its annexation is such, the voice signal receiving circuit becomes the electric pulse input with voice signal and triggers delay control circuit, the surround lighting receiving circuit is transformed to the signal of telecommunication with ambient light illumination, is connected on the input that triggers delay control circuit, is used to change trigger sensitivity; The system that connects that the output of triggering delay control circuit is connected on thyristor extremely goes up, thyristor and controlled lamp series connection are on AC power, and the power supply step-down rectifying circuit AC power of will throwing light on is transformed to low-voltage DC and gives sound light control circuit and trigger delay control circuit operating voltage is provided.

The voice signal receiving circuit is made up of microtelephone and related elements, the faint extraneous sound can be transformed to electric impulse signal, play trigger late-class circuit effect, the surround lighting receiving circuit is by light-sensitive element such as photodiode, photosensitive triode or photo resistance are formed.Because it is connected between the input and dc power anode end that triggers delay control circuit, therefore, its internal resistance changes will directly influence the current potential that triggers the delay control circuit input.And the height of this current potential has determined to trigger the trigger sensitivity of delay control circuit, and current potential is high more, and trigger sensitivity is low more.When ambient light illumination was strong, the internal resistance of light-sensitive element was less, made the current potential that triggers the delay control circuit input higher, thereby greatly reduced trigger sensitivity.Even at this moment voice signal is arranged, circuit can not be triggered yet.When ambient light illumination weakens to a certain degree the time, the light-sensitive element internal resistance increases, and the current potential that triggers the delay control circuit input reduces, and trigger sensitivity improves.At this moment if any voice signal, circuit just is triggered, the thyristor conducting, and bulb is lighted.Between the bulb light emission period.The current potential height that triggers the delay control circuit input is with inoperative, and the length of delay time only by the circuit parameter decision, has so just guaranteed that light-sensitive element receives only a little less than the environmental light intensity, and do not received the illumination of controlled lamp.

Trigger delay control circuit and be made up of integrated circuit and related elements, it has an input, an output and a time delay process.The length of delay time can be adjusted in the scope at tens minutes by the numerical value decision of the resistance capacitance of time delay process.

Be connected on the thyristor that triggers the delay circuit output,, directly be switched on or switched off the power supply of lamp as noncontacting switch.In order to prolong bulb life, generally select unidirectional thyristor for use, when making bulb luminous, only obtain the rated power of half approximately, luminosity is lower than normal brightness, and bulb life is prolonged greatly.When being necessary, also bidirectional thyristor can be selected for use, normal brightness can be reached when bulb is luminous.

The utlity model has characteristics such as reliability height, economize on electricity is practical, installation is simple, easy to use.It all is made up of electronic component, does not have the mechanical organ of ordinary lamps switch, does not therefore have wearing and tearing, anti-vibration, has very high reliability.Because its working method, make controlled corridor lamp realize that do not work daytime, there is the people bright during night, the people crosses from the process of putting out, greatly avoided waste of electric energy, and prolonged useful life of bulb, compare with present ubiquitous altar lamp, but saves energy and bulb expense reach more than 90 percent.Its installation is also very simple, only needs to be connected in series in existing bulb circuit to get final product, because light-operated circuit receives only the power of surround lighting, does not play use after lamp is bright, and therefore, the position that it is installed also can be selected arbitrarily.Generally be screwed near controlled lamp, need do not avoid the illumination of controlled lamp.To the place of new installation illuminating lamp, the utility model can be made into the structure of switch and lamp holder one, promptly becomes acousto-optic control automatic time delay lamp holder.It is different with the connected mode of controlled lamp that difference between them only is, acousto-optic control Auto-delay switch is connected with controlled lamp with lead, the quantity of controlled lamp is not limit, and acousto-optic control automatic time delay lamp holder is connected as a single entity control circuit and lamp holder, only controls a lamp during use.Because the utility model triggers with voice signal, the people is arranged through out-of-date night, footsteps or slight applause can make lamp light automatically, and people's time-delay later extinguishes, and the action that need choose is not turned on light and turned off the light, and therefore, brings great convenience to people.
