Embodiment
As shown in Figure 1, this electric ballast is by rectification circuit, electronic ballast circuit, and voltage stabilizing circuit, control circuit, current foldback circuit, low-pass filter circuit, receiving circuit and radiating circuit are formed.Rectification circuit, electronic ballast circuit, control circuit and current foldback circuit constitute an electric loop, are controlled the break-make in this loop by control circuit.
Civil power is through rectification circuit, rectification goes out dc pulse moving voltage, send electronic ballast circuit and voltage stabilizing circuit respectively, the output of voltage stabilizing circuit connects control circuit and receiving circuit, for control circuit and receiving circuit provide D.C. regulated power supply, the output of receiving circuit connects the low-pass filtering road, and low-pass filter circuit is used for filtering household appliance remote control signal and extraneous noise signal.When receiving circuit was received the control signal of radiating circuit transmission, signal process low pass filtered circuit is trigger control circuit then, makes the control loop conducting that originally ended, thus the circuit closed of control electronic ballast circuit, and fluorescent lamp is bright.When receiving circuit is received the signal of radiating circuit transmission again, the control circuit upset, control loop ends, and makes the electronic ballast circuit loop disconnect, and fluorescent lamp extinguishes.The just corresponding conducting of the every emission pulsatile once of radiating circuit signal, control circuit or by once.
Figure 2 shows that pulse radiating circuit schematic diagram, this circuit constitutes an astable multivibrator.
Power supply GB powers 4 pin and 8 pin that voltage is added to time-base circuit 555 by K switch 1 to it.Supply voltage is added to 2 pin and 6 pin of time-base circuit 555 through R2, receives 7 pin through R1 again, 5 pin other end ground connection of C1 one termination time- base circuit 555, and 6 pin of C2 one termination base circuit 555 and the 2 pin other ends are ground connection also.Output 3 pin of time-base circuit 555 constitute launching circuit through R3 and VD1 one end ground connection.
Select the frequency of oscillation of multivibrator identical with the frequency, demodulation frequency of infrared receiving terminal.Whenever press K switch 1 one time, the astable multivibrator starting oscillation, oscillating impulse is launched by infrared transmitting tube VD1 after resistance R 3 current limlitings.
Fig. 3 receives and the control circuit schematic diagram for electric ballast, and wherein a end connects the earth terminal in electric ballast loop; B end connects the rectification circuit anode end, for receiving and control circuit provides power supply; C termination power ground.
1 pin by integrated infrared receiving terminal PH connects by R5, and the low pass that C4 constitutes is considered wave circuit and formed receiving element; Integrated circuit T is a double D trigger, and its output 13 pin are through the control utmost point G of resistance R 7 connection one-way SCR VS, and through capacitor C 8 connection power supply ground, this part is formed control unit; The common port of the one end connection voltage stabilizing didoe D1 of resistance R 4 and capacitor C 3, C7 parallel circuits, the other end earthing potential of this parallel circuits, the circuit output end of pressure-stabilizing that this part constitutes is connected to 5,14 pin of integrated circuit T and 2 pin of PH, for T and PH provide power supply.Integrated circuit T is connected into a monostable circuit and a bistable circuit respectively, and monostable circuit is carried out the pulse stretching shaping to triggering signal, and bistable circuit is used for driving one-way SCR VS.
When infrared receiving terminal PH receives the infrared pulse signal identical with self frequency, demodulation frequency, 1 pin of infrared receiving terminal PH will produce the negative pulse of a saltus step, undersuing is through low-pass filter circuit, filter out high-frequency signal and interference signal and pass through the integrating effect of capacitor C 5 again, producing a negative spike triggering monostable circuit makes the monostable circuit upset enter transient state, output 1 pin of integrated circuit T is a high level by original low transition, this high level charges to C6 through R8, making 4 pin is that the R8 terminal potential rises, when rising to reset level, monostable circuit resets, and 1 pin recovers low level.So when receiving infrared remote-controlled signal, 1 pin is just exported the positive pulse of a fixed width, this positive pulse will directly be added to 11 pin, make the bistable circuit upset once, its output Q i.e. 13 pin level just changes once, and when 13 pin were high level, the control utmost point G of one-way SCR VS obtained the forward trigger current and conducting by R7, the electronic ballast circuit loop is connected, and can light fluorescent tube.When infrared receiving terminal PH receives infrared pulse signal again, make the bistable circuit upset once, 13 pin output low levels, one-way SCR VS loses trigger current, turn-offs when the alternating current zero passage, and the electronic ballast circuit loop disconnects, and fluorescent lamp extinguishes.Therefore, whenever press the action that No. a time remote controller just can be realized " opening ", " pass " fluorescent lamp.
Semistor RT is connected between silicon controlled negative electrode K and the earth potential as current foldback circuit, plays the effect of overcurrent protection.When " lamp does not start " abnormality takes place; the electric ballast loop current increases; this moment, thermistor RT uprushed above Curie-point temperature because of the overcurrent temperature of being heated; resistance increases; the voltage major part is fallen on the PTC element; power tube just can not vibrate, and quits work, thereby has protected electric ballast.At the controllable silicon two ends, promptly anode A and negative electrode K go up and are connected to K switch 2, can stir functional shielding K switch 2 closures, close distant control function, just can work as general electric ballast and use, but still have overcurrent protection function.
Referring to Fig. 4, spherical male lens 1 are installed in infrared receiving terminal PH front at ballast, are inlaid on the housing 3 of ballast, and spherical male lens 1 can increase the receiving range that receives head, can remedy and receive the little shortcoming of a receiving angle, allow the user carry out remote control in a plurality of angles.Between spherical male lens 1 and infrared receiving terminal PH, also have a red filter plate 2, be used to filter out the color of other wavelength, only permitted redness and pass through, further improved the antijamming capability of circuit.
The infrared mode remote control is adopted in this product remote control.Utilize its directivity, the direction that the remote controller aligning receives during use gets final product, and can avoid misoperation.Remote control switch adopts a some flowing mode, and therefore circuit no power at ordinary times, but the time that each crawl only the needs 1-2 second break-make of trigger control circuit just also be extremely power saving.Element adopts surface mount elements and button electricity Duo, and remote controller can be accomplished very little, makes ornament and be attractive in appearancely conveniently to carry again.If the user does not need distant control function, also can stir the functional shielding switch, close distant control function, just can work as general electric ballast and use, and have overcurrent protection function.
The utility model can be widely used in places such as family, office, has to install easily, and is easy to use, the reliability advantages of higher.
