Description
The utility model belongs to a kind of AC power remote control switch control circuit in the semiconductor electronic industry.
Remote control switch in the market is broadly divided into radio remote switch; Infrared telecontrol switch; Inferior ultra-sonic remote control switch.Because the communication media difference that this switch uses also just has different shortcomings, wherein most importantly the quantity of these remote control circuits institute energy remote control switch is limited.If want remote control two-way or tens road above switches, just need to increase volume, improve cost.And these remote control switches also have a defective to be exactly in use: phase mutual interference easily.The meeting interfering TV that has in use of wireless remotecontrol wherein.Infrared switch mostly uses is that controller is made in remote control on the TV.Just having caused of having like this used can not be with television identical the time.And inferior supersonic switch can send ear-piercing noise in use, and is interfered easily, thereby produces wrong on-off phenomenon, brings unnecessary trouble to the people.Also has a kind of the two poles of the earth soft-touch control in addition, though stability is good, be difficult for being interfered, but that it must touch with hand is could switching circuit very inconvenient, and laser remote-controlled switch has added laser remote-controlled on the basis of this two poles of the earth soft-touch control and succeed in developing.
Develop the laser remote-controlled purpose of this utility model and have two kinds: the first, both solved existing various types of remote control switch problem of remote control two-way or tens road above switches simultaneously, solved the shortcoming that the two poles of the earth soft-touch control can not carry out remote control again.Maximum purpose of the present utility model with regard to provided a kind of in a space with a miniature laser reflector can remote control switch be the incalculability restriction, and can the phase mutual interference.The second, it has utilized a kind of volume small, can be placed on the key chain, and have the joyful again generating laser of multiple use to make the reflector of this remote control switch, it is motionless so just to allow the people do, and comes the switch of all electrical equipment in the remote control man with a miniature transmitter.
The utility model adopts technical scheme as described below for achieving the above object:
Laser remote-controlled switch receives control switch by a generating laser and remote control and forms.Generating laser is exactly the portable semiconductor laser of selling in the market of adorning 3 joint button cells.Remote control receives control switch and is made up of power input, power output end, a current rectifying and wave filtering circuit and a control circuit, current rectifying and wave filtering circuit is formed current rectifying and wave filtering circuit output DC source by two diodes, a zener diode and an electrochemical capacitor; Control circuit by a bidirectional triode thyristor and one by integrated package 555, two photo resistance that parameter equates, an electric capacity, a current-limiting resistance and the light-operated bistable circuit that light-emitting diode is formed, two parameters equate to be connected on after photo resistance is connected the two ends of the DC power supply of current rectifying and wave filtering circuit output, after connecting together, the 2nd pin of integrated package 555 and the 6th pin be connected on the line between two photo resistance, the 3rd pin of integrated package 555 is connected on the control end of bidirectional triode thyristor after as control output end series connection upper flow resistance and light-emitting diode, and bidirectional triode thyristor is connected on the front end of laser remote-controlled Switching Power Supply output.
Luminous point with generating laser shines two photo resistance respectively, can make the 3 pin output high potential or the electronegative potential of integrated package 555, thereby the conducting of control bidirectional triode thyristor or end can realize unlatching, the closure of laser remote-controlled switch.
The laser remote-controlled switch that adopts the foregoing circuit principle to make, concentrate because the laser spots that generating laser sends is bright, therefore in a space, utilize a generating laser with regard to the numerous switch of may command, its novel structure, circuit is simple, working stability is reliable, with low cost, be a kind of convenient and practical novel remote control switch.
