Refer to Fig. 3 to 5, Fig. 3 is the structural representation of another execution mode of electric ballast of the present invention, and Fig. 4 is the structural representation of the stepless knob shown in Fig. 3, and Fig. 5 is the circuit diagram that the driver module shown in Fig. 3 is connected with stepless knob.In present embodiment, electric ballast comprises stepless knob 310, driver module 320 and display module 330.Stepless knob 310 is basic identical with stepless knob and driver module in a upper execution mode with driver module 320.
More optimally, driver module 320 comprises testing circuit 321, control circuit 322 and the drive circuit 323 of order electrical connection, and testing circuit 321 is electrically connected with stepless knob 310, and control circuit 322 is electrically connected with display module 330, and drive circuit 323 is electrically connected with external light source (not shown).Wherein, the command signal that testing circuit 321 produces for detection of described stepless knob 310 rotates, and export described control circuit 322 to.In present embodiment, the control circuit 322 of driver module 320 is a microcontroller 322.Control circuit 322 is determined the speed of rotation of stepless knob 310 for rotating according to described stepless knob 310 command signal producing, and then according to the speed of rotation of described stepless knob 310, adjust the output to the power output of external light source, and to described drive circuit 323 transmit power command, the power instruction of drive circuit 323 for sending according to described control circuit 322, the power output to described external light source output after described control circuit 322 regulates.Meanwhile, performance number after adjusting is sent to display module 330 by control circuit 322, so that display module 330 shows the power output of current driver circuit 323 in real time.
In conjunction with Fig. 6 and Fig. 7, Fig. 6 is the turn clockwise waveform schematic diagram of period 1 signal of telecommunication combination of output of the rotating mechanism of stepless knob in Fig. 4, and Fig. 7 is the waveform schematic diagram that in Fig. 4, the rotating mechanism of stepless knob is rotated counterclockwise signal of telecommunication combination second round of output.In the time that the rotating mechanism 311 of stepless knob 310 rotates, the first pin 312 is exported period 1 signal of telecommunication a to described testing circuit 321, the second pin 313 is exported signal of telecommunication b second round to described testing circuit 321, and described period 1 signal of telecommunication a is identical with the cycle of signal of telecommunication b second round.Period 1 signal of telecommunication a and second round signal of telecommunication b composition combination can be following four kinds of level states: the first state 1, period 1 signal of telecommunication a be the low level signal of telecommunication and second round signal of telecommunication b be the high level signal of telecommunication; The second state 2, period 1 signal of telecommunication a and second round signal of telecommunication b be all the low level signal of telecommunication; The third state 3, period 1 signal of telecommunication a be the high level signal of telecommunication and second round signal of telecommunication b be the low level signal of telecommunication; The 4th state 4, period 1 signal of telecommunication a and second round signal of telecommunication b be all the high level signal of telecommunication.Described rotating mechanism 311 is in the time turning clockwise, export described period 1 signal of telecommunication a, signal of telecommunication b composition period 1 signal of telecommunication combination second round (as shown in Figure 6), the level state of described period 1 signal of telecommunication combination is 1,2,3,4 according to temporal order circulation.Described rotating mechanism 311 is in the time being rotated counterclockwise, export described period 1 signal of telecommunication a, signal of telecommunication b composition signal of telecommunication second round combination second round (as shown in Figure 7), the level state of described signal of telecommunication combination second round is 4,3,2,1 according to temporal order circulation.A circulation of described signal of telecommunication combination first/second round is one-period.
Meanwhile, the first pin 312 of stepless knob 310 produces respectively with the second pin 313 period 1 signal of telecommunication a, the second round cycle of signal of telecommunication b is relevant with the speed of rotation of stepless knob 310.When the rotating mechanism 311 of stepless knob 310 rotates sooner, period 1 signal of telecommunication a, the second round cycle of signal of telecommunication b is less, when the rotating mechanism 311 of stepless knob 310 rotates slowlyer, period 1 signal of telecommunication a, the second round cycle of signal of telecommunication b is larger.Be the cycle that stepless knob 310 rotations produce signal of telecommunication combination first/second round to become large with the increase of the speed of rotation.It should be noted that, in the present invention, the cycle of first, second periodic electric signal of stepless knob and the speed of rotation are also first not only above-mentioned proportional relationship, in the execution mode of other stepless knobs of use, can be for the cycle of first, second periodic electric signal diminishes with the increase of the speed of rotation of stepless knob, therefore the relation between the speed of rotation of the cycle to first, second periodic electric signal and stepless knob is not done unique restriction.
The signal of telecommunication combination first/second round that 310 rotations of stepless knob produce exports the testing circuit 321 of driver module 320 to as command signal, testing circuit 321 detect stepless knob 310 generation command signal and export control circuit 322 to.
Particularly, control circuit 322 obtained the speed of rotation of stepless knob 310 every the default very first time, periodically to determine the rate of change of the power exported of current driver circuit 323, and then within each default very first time, regulate the power output of drive circuit 323 according to the rate of change of power output within the current default very first time.Further particularly, control circuit 322 is every the default very first time, the periodicity of the statistics described command signal that described testing circuit 321 detects within default the second time, the cycle of the command signal producing due to stepless knob 310 increases and becomes large with the speed of rotation of stepless knob 310, therefore can reflect the cycle variation of described command signal within the default very first time according to the periodicity of command signal in default the second time, and then symbolize the speed of rotation of described stepless knob 310 within the current default very first time.Control circuit 322 obtains the rate of change of described power output within the described current default very first time according to the periodicity of the speed of rotation in the described sign current preset very first time and default the first mapping relations, with the basis power output that the rate of change of power output regulates described drive circuit 323 to provide to external light source within the described current preset very first time within the described current default very first time.Wherein, the default very first time is greater than or equal to default the second time.
In present embodiment, control circuit 322 is at the local first mapping relations table of preserving of electric ballast, for example, described default the first mapping relations are specially: when the described command signal periodicity within described default the second time is less than or equal to default the first numerical value, the rate of change of described power output is V
p1; When described command signal periodicity within described default the second time is greater than default the first numerical value and is less than default second value, the rate of change of described power output is V
p2; When described command signal periodicity within described default the second time is greater than default second value, the rate of change of described power output is V
p3; Wherein, V
p1, V
p2, V
p3be respectively different numerical value, V
p1, V
p2, V
p3magnitude relationship for order increase progressively.Certainly, in other embodiments, default the first mapping relations can also be the rate of change V that presets described command signal periodicity K and power output in the second time described
pfor proportional relationship is V
p=KN, wherein, N is a positive count.Further, in other embodiments, the rate of change V of described command signal periodicity K and power output within described default the second time
wcan also be set to inversely prroportional relationship, within described default the second time, described command signal periodicity K is more, and the speed of rotation that characterizes stepless knob is larger.In addition, the first mapping relations are not limited to the mapping relations between interior command signal periodicity of default the second time and power output rate of change, can also be the mapping relations between cycle size and the power output rate of change of command signal, control circuit obtains the cycle size of command signal by the level state 1,2,3,4 that detects command signal, and then can be determined the rate of change of power output by above-mentioned mapping relations.Therefore the first mapping relations in the application can be set as reflecting any mapping relations of the relation between the rate of change of the stepless knob speed of rotation and power output as the case may be.
For better explanation the application electric ballast, further describe for example, the current power to external light source output of drive circuit 323 is 1000W, now user's rotating mechanism 311 of stepless knob 310 that turns clockwise, testing circuit 321 detects the command signal that stepless knob 310 produces and exports control circuit 322 to, it is period 1 signal of telecommunication combination that control circuit 322 is judged the command signal that stepless knob 310 produces, and is defined as increasing power output.Meanwhile, control circuit 322 obtains the speed of rotation of stepless knob 310 for 5 seconds every the default very first time.In control circuit 322 rotate at stepless knob 310 first 5 seconds statistics wherein in default 1 second the second time the periodicity K of command signal be 31, according to being pre-stored in the first local mapping relations, when K<=20, the rate of change of power output is V
p1=10W/S; When 20<K<40, the rate of change of described power output is V
p2=20W/S; In the time of K>=40, the rate of change of described power output is V
p3=50W/S, control circuit 322 determines that the rate of change of power output in first 5 seconds is V
p2=20W/S, it is control circuit 322 regulated drive circuit 323 in first 5 seconds power output with the rate of change of 20 watts of increases per second, the also current power output of display driver circuit 323 per second of display module 330 simultaneously, as first second 1020W, the 5th second 1100W of second second 1040W.......In stepless knob 310 rotations, after first 5 seconds, the power output of drive circuit 323 is 1000+20*5=1100W.In like manner, at second in 5 seconds, control circuit 322 is determined the rate of change second power output in 5 seconds as aforesaid way, so analogize, until stepless knob 310 stops the rotation, when testing circuit 321 can't detect the command signal of stepless knob 310 rotation generations, control circuit 322 makes drive circuit 323 keep current power output.
It should be noted that, above-mentioned default first, second time and default the first mapping relations can be electronic ballast system default setting, also can be arranged the input of specific input module in advance by user, in this no limit.
In addition, control circuit in the present invention also may not only limit in the time that stepless knob turns clockwise, increase power output, in the time that stepless knob is rotated counterclockwise, reduce power output, in other embodiments, control circuit also can, in the time that stepless knob turns clockwise, reduce power output, in the time that stepless knob is rotated counterclockwise, increase power output, therefore also do not do unique restriction at this.
