Followingly the utility model is further specified with reference to accompanying drawing

Fig. 1 is rectifying and wave-filtering+6V voltage stabilizing circuit, and for the control circuit of Fig. 2, Fig. 3 provides D.C. regulated power supply, Fig. 1 is that common circuit does not repeat them here.

Fig. 2 is preposition amplification and pulse shaping circuit, its effect is that the infrared encoded signal that any remote controller sends is amplified, produce a pulse signal, trigger IC4 and the IC5 of Fig. 3 simultaneously, make IC4 demonstrate the luminosity of light modulation speed controller, the state of speed with numeral 1,2,3,4,5,6,7,8,9, also make photoelectrical coupler light-adjusting and speed-adjusting circuit produce corresponding with it luminosity, speed under Q0, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, the Q9 output signal of IC5 drive, the entire work process of this circuit sees the oscillogram of Fig. 4 for details.

When this circuit sent electricity, 2 of IC2 exported the voltage of an about 0.7V, and charged to C7 through R2, very fast C7 positive pole just is charged to about 0.6V, triode Q1 becomes conducting by ending, and 2 pin of IC3 are by high level 6V step-down level 0V, and output 3 pin of IC3:A NAND gate also become high level by low level; Because charge circuit+6V---R4---C8---VSS charging is slower, send pass through 1.1R4C8 ≈ 0.5S approximately behind the electricity after, the anodal putting high level voltage V that just is charged to 6 pin of IC3 of C8 _1H(about 4V), the output counter-rotating of IC3:B NAND gate becomes low level by high level, so after sending electricity, light-emitting diode D7 is approximately through just being gone out by bright change behind the 0.5S.The C9 of Fig. 3, R6 are the reset circuits that IC4, IC5 misoperation add when preventing to send electricity, make when sending electricity, the output LED charactron of IC4 shows " 0 ", the output Q0 of IC5 is a high level, because Q0 is unsettled, photoelectricity coupling light modulation, the output of speed regulator no-voltage, expression is the halted state of light modulation, speed governing at this moment, at the reset circuit reseting period, by Infrared remote controller is to produce light modulation, speed governing action, have only after 1.1R6C9 ≈ 3.6S resetting time, just play light modulation, speed governing effect by Infrared remote controller.

When after resetting time, aim at this circuit by Infrared remote controller, Infrared remote controller can be sent a series of code signal, and the width t2 of a general group coding signal is 5ms, former and later two code signals t3 at interval are generally 35ms, and the cycle of code signal is all less than 100ms (generally about 40ms).When infrared receiving diode receives the infrared remote-controlled signal of any household electrical appliance, no matter this code signal waveform of 2 pin of IC2 output how, each group coding signal of dissimilar Infrared remote controller emission is that the pulse duration difference or the pulse number of high-low level is variant, the centre of each group coding signal always has a high level pulse width little, the signal that the low level pulse width is big, then should organize signal through R2, behind the C7 shaping filter, the B pin voltage of Q1 is lower than 0.6V (seeing that the Q1-B oscillogram 1.), even the B pin of Q1 can not get the moment direct voltage less than 0.6V in this group coding signal, after this group signal ended, the B pin of Q1 also can obtain a moment direct voltage less than 0.6V (seeing that the Q1-B oscillogram 2.), triode Q1 is become by conducting to be ended, 2 pin of IC3 become high level by low level, the counter-rotating of IC3:A NAND gate, the 3 pin output of IC3 becomes low level by high level; C8 discharges rapidly through D6, the 6 pin voltages of IC3 become 0.6V by high level, the counter-rotating of IC3:B NAND gate, and it is exported 4 pin and becomes high level by low level, this gives 1 pin of IC4 and 14 pin of IC5 by the rising edge that low level becomes high level, is used for triggering IC4 and IC5 and carries out the digital display light-adjusting and speed-adjusting.Because the only several milliseconds of the width of each group coding signal, even the B pin of Q1 occurs repeatedly＜the moment direct voltage of 0.6V, 2 pin of IC3 become high level by low level again, the 3 pin output high level step-down level of IC3, again and again, (less than several milliseconds) can't make capacitor C 8 charge to high-level input voltage V between 3 pin of IC3 output high period _1H(4V), because C8 will be charged to 4V, need through about 0.5S, even hand is pinned remote controller and is sent a string code signal always, because the time interval of each group, also in 100ms, reason was the same, even 3 pin of IC3 are also repeatedly exported high level, the time of this 100ms also can't make capacitor C 8 be charged to 4V, and 4 pin of interior IC3 are always exported high level during this period of time.Promptly no matter can make the B pin of Q1 moment direct voltage occur repeatedly less than 0.6V by how long producing continuous time of an Infrared remote controller an a string code signal or a group coding signal, all because 3 pin of IC3 are exported the time of high level (less than the width of each group coding signal or the blanking time between group and the group, generally all less than 100ms) be charged to time (0.5S) of 4V by 0.6V much smaller than C8, make 6 pin of IC3 can't reach high-level input voltage (4V), the 4 pin output of IC3:B can't be reversed, and 4 pin of IC3 can only be exported one and effectively trigger IC4, the rising edge of a pulse of IC5.

The clock diablement pin 2 pin ground connection of the IC4 of Fig. 3, lantern test pin 14 pin are ground connection also, make IC4 carry out decimal system counting, the tripod of IC4 connects+the 6V power supply, makes " 0 " state output of IC4 show " 0 ", rather than blank, make the people come into plain view just know it is " pass " state.The 13 pin clock diablement ends of IC5 are ground connection all, IC5 also is connected into decimal system decoding output counter makes IC4 corresponding with IC5 output, the clock trigger signal of 1 pin of IC4 and 14 pin of IC5 is all from the 4 pin output pulse signal CLK of Fig. 2 IC3:B, IC4, IC5 is the rising edge trigger action, the 15 pin preset signals of 15 pin of cmos circuit IC4 and IC5 are all by C9, the reset circuit that R6 forms is realized, zero clearing resets when making power on circuitry, all zero setting of IC4 and IC5, IC4 is output as " 0 " state, show by 7 sections LED charactrons, and the Q0 of IC5 output high level (6V), other output output low level, because of the Q0 output of IC5 unsettled, do not connect photoelectricity coupling light modulation speed controller, the light modulation speed controller output voltage is 0V, so LED demonstration " 0 ", corresponding to " pass " state of light modulation speed controller.After IC4, IC5 finish and reset, promptly produce a rising edge trigger impulse CLK by an Infrared remote controller, so IC4 and IC5 meeting synchronization action under the driving of identical clock signal clk, show " 1 ", corresponding to Q1 is high level, this high level makes 1 grade of voltage of light modulation speed controller output after the coupling of R7 current limliting photoelectricity; Whenever by a remote controller, produce a CLK trigger impulse later on, IC4 and IC5 move once simultaneously, 2 grades of voltages of output when showing " 2 ", " 3 "---3 grades, " 4 "---4 grades, " 5 "---5 grades, " 6 "---6 grades, " 7 "---7 grades, " 8 "---8 grades, " 9 "---9 grades, " 0 "---close, move in circles.Fig. 3 circuit photoelectricity coupling light modulation, utilize D8 in the alignment circuit---the unilateral conduction of D17 diode makes Q0, Q1, Q2, Q3, Q4, Q5, Q6, Q7, Q8, isolate mutually between the Q9, D18 both can make hypotensive effect, can work as the indicator light of receiving infrared signal again uses, the output voltage of bidirectional triode thyristor SCR1 is between 220～40V AC between current-limiting resistance R7-R16 value 0.2～1.3K, resistance R 18 is parallel on the light resistance R17, can play the effect of regulated output voltage, capacitor C 10 plays dividing potential drop phase shift effect, and resistance R 19 and bidirectional trigger diode DIAC play current limliting and trigger action.XS is for connecting light modulation, the speed governing socket of pendent lamp or ceiling fan, and the resistance on the schematic diagram, electric capacity are except that indicating especially, and all the other resistance are selected the resistance of 0.5w for use, and electric capacity is selected the withstand voltage electric capacity of 50V for use.
