Description

Energy saving and timing lamp socket controlled by sound or light

The utility model relates to a kind of time-delay lamp holder.

In today of energy deficiency, saves energy is significant.Be to solve " altar lamp " problem that the public place exists, some have developed the time delayed turn-off switch, but that the static state of these switches is kept dynamo-electric stream is bigger, more effectively saves energy.

The purpose of this utility model provides a kind of time-delay lamp holder that is subjected to the control of light harmony, under the environment that light becomes clear, the acoustic control part of lamp holder is not worked, it not only makes keeps the greatly minimizing of dynamo-electric stream, also can prevent from when light is bright, to light the situation appearance of bulb, so just further save power consumption owing to the acoustic control effect.

The purpose of this utility model is achieved in that the energy-conservation time-delay lamp holder of photoacoustic dual-controlled is made of last lamp holder, following socket and control circuit.Said control circuit is made up of pick-up, photo resistance, rectifier, special-purpose thick film integrated circuit, monostable trigger and transistor.Wherein: said pick-up connects said transistorized base stage, this transistorized collector electrode output connects the set end of said monostable trigger through acoustic pressure adjusting resistance and differential circuit, the output one tunnel of this monostable trigger connects the triggering input of said thick film circuit, another road connects the reset terminal of said monostable trigger through delay circuit, the output of said rectifier connects the power input of said thick film circuit, said photo resistance connects the control input end of said thick film circuit, the dc power output end of said thick film circuit connects said monostable trigger and transistorized power end, and the ac power output of said thick film circuit connects said socket down.

Thick film circuit has or not DC power supply output to be controlled by photo resistance.When light was bright, thick film circuit did not have direct current output, and the acoustic control part is not worked, and at this moment no matter had or not sound control signal, and thick film circuit all can make lamp holder not have the output of AC load voltage because of not triggering input.Only under the condition of dim light, thick film circuit just has DC power supply output, at this moment if there is sound to be searched by pick-up, this signal just produces pulse by differential circuit after transistor amplifies, trigger monostable trigger, after thick film circuit is received the triggering signal of monostable trigger, just, the bulb that is connected on down socket is lighted from its ac power output output AC power source.After delay circuit produced one section time-delay, delay circuit resetted monostable trigger again, so thick film circuit does not have alternating voltage output, bulb extinguishes.

The utility model utilizes the light-operated effect of photo resistance, the power supply that when light is bright, cuts off the acoustic control part, not only reduced to keep dynamo-electric stream greatly, also can prevent from when light is bright, to light the situation appearance of bulb, thereby have tangible power savings because of the acoustic control effect.

Below in conjunction with drawings and Examples the utility model is described in detail.

Fig. 1 is an outline drawing of the present utility model; Fig. 2 is the control circuit schematic diagram.

The utility model is by the last lamp holder 1 shown in the figure, down socket 2 and the control circuit that is contained in the lamp holder constitute.Control circuit among Fig. 2 is that special-purpose thick film integrated circuit 8, monostable trigger 9 and the transistor 10 of WNHM formed by pick-up 3, photo resistance 4, full-bridge rectifier 7, model.Comprise noncontacting switch, direct current output, photo-electric control, work indication in the special-purpose thick film integrated circuit 8, trigger unit such as input, monostable trigger 9 is made of rest-set flip-flop.Wherein: power input 1,7 pin of special-purpose thick film integrated circuit 8 connect the output of full-bridge rectifier 7, light-operated pin 3 and 4 connects photo resistance 4, indication pin 5,6 connects the light-emitting diode 6 that this lamp holder of indication position is used, dc output end 9,7 pin are as the power end of steady trigger 9 of the power supply order of acoustic control partial circuit and transistor 10,

ac output end

2,12 pin connect with following socket 2, are used to connect the load bulb.Pick-up 3 is connected on the base stage input circuit of transistor 10, the collector electrode output of transistor 10 is regulated resistance 5 through acoustic pressure and is connect RC differentiator, the S set end of the steady trigger 9 of output order of this differential circuit, the Q output one tunnel of monostable trigger 9 connects the triggering input 8 of special-purpose thick film integrated circuit 8 through resistance, another road connects rc-delay circuit, the R reset terminal of the steady trigger 9 of the output of this delay circuit (taking from electric capacity) order.

Have four windows on the last lamp holder 1, pick-up 3, photo resistance 4, acoustic pressure regulate resistance 5 and light-emitting diode 6 exposes from these windows.

Narrate its operation principle below:

When light became clear, the photo resistance resistance diminished, and thick film circuit does not have DC power supply output, and acoustic control does not at this moment partly have electricity and do not work, and so no matter have or not sound control signal, thick film circuit all can not get triggering input signal, and lamp holder does not have AC load voltage and exports.

Under the situation of dim light, the resistance of photo resistance 4 increases, and thick film circuit 8 just has DC power supply to export, make acoustic control partly electric work.At this moment if there is sound to be searched by pick-up 3, this signal just amplifies through transistor 10, and produces pulse by differential circuit, with monostable trigger 9 set, so thick film circuit 8 is triggered by monostable trigger 9, and light by the bulb that its ac power output will be connected on down socket 2.Meanwhile, DC power supply is charged to delay circuit through the Q of monostable trigger 9 output, through after a while, reset input during threshold value when what the current potential on the electric capacity in the delay circuit was charged to monostable trigger 9, monostable trigger is reset again, so special-purpose thick film integrated circuit 8 cuts off its alternating voltage output again, and the load bulb is extinguished.

In the foregoing circuit because of adopting rest-set flip-flop, reception be pulse signal, during bulb is lighted in, because of trigger is set, so the sound control signal that pick-up is searched can not make rest-set flip-flop trigger once more, also i.e. sound control signal conductively-closed at this moment.But in actual applications, often have and whenever send sound control signal and wish that just bulb lights the requirement of a period of time, can pick out a transistor 11 from the collector electrode of transistor 10, with the reset terminal of the steady trigger 9 of collector electrode order of transistor 11, grounded emitter for this reason.Like this during bulb is lighted, if receive sound control signal again, this signal will make transistor 11 conductings by transistor 10, thereby the charge discharging resisting of being deposited on the electric capacity in the delay circuit is fallen, so circuit is trigger again, make bulb continue to light one section delay time.
