More optimally, driver module 320 comprises testing circuit 321, control circuit 322 and the drive circuit 323 that order is electrically connected, and testing circuit 321 is electrically connected with stepless knob 310, control circuit 322 is electrically connected with display module 330, and drive circuit 323 is electrically connected with external light source (not shown).Wherein, testing circuit 321 rotates and the command signal produced for detecting described stepless knob 310, and exports described control circuit 322 to.In present embodiment, the control circuit 322 of driver module 320 is a microcontroller 322.The command signal that control circuit 322 produces for rotating according to described stepless knob 310 determines the speed of rotation of stepless knob 310, 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, exports the power output after described control circuit 322 regulates to described external light source.Meanwhile, performance number after adjustment is sent to display module 330 by control circuit 322, with the power output making display module 330 show current driver circuit 323 in real time.
Stepless knob 310 in present embodiment is specifically described, stepless knob 310 comprises the rotating mechanism 311 for Linear Rotation, and stepless knob 310 also comprises the first pin 312, second pin 313, three-prong 314, the 4th pin 315 and the 5th pin 316.Wherein, three-prong 314, the 4th pin 315 and the 5th pin 316 are for ground connection.Described first pin 312, second pin 313 is electrically connected with the testing circuit 321 of driver module 320 respectively, and be connected with two input and output (IO) ports of control circuit 322, to export the signal of telecommunication to control circuit 322 respectively to testing circuit 321 respectively by testing circuit 321.
Composition graphs 6 and Fig. 7, Fig. 6 is that the rotating mechanism of stepless knob in Fig. 4 turns clockwise the waveform schematic diagram of the period 1 signal of telecommunication combination exported, and Fig. 7 is the waveform schematic diagram that the rotating mechanism of stepless knob in Fig. 4 is rotated counterclockwise signal of telecommunication combination second round of output.When the rotating mechanism 311 of stepless knob 310 rotates, first pin 312 exports period 1 signal of telecommunication a to described testing circuit 321, second pin 313 exports 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 form 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; 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; 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 when 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 when 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.The signal of telecommunication combined a circulation and was one-period described first/second round.
Meanwhile, stepless knob 310 the first pin 312 and the period 1 signal of telecommunication a that the second pin 313 produces respectively, second round signal of telecommunication b cycle relevant with the speed of rotation of stepless knob 310.When the rotating mechanism 311 of stepless knob 310 rotates faster, period 1 signal of telecommunication a, second round signal of telecommunication b cycle less, when the rotating mechanism 311 of stepless knob 310 rotates slower, period 1 signal of telecommunication a, second round signal of telecommunication b cycle larger.Namely stepless knob 310 rotate the generation signal of telecommunication first/second round combination cycle become large with the increase of the speed of rotation.It should be noted that, cycle of first, second periodic electric signal of stepless knob and the speed of rotation in the present invention be first not only above-mentioned proportional relationship, in the execution mode using other stepless knobs, can diminish with the increase of the speed of rotation of stepless knob for the cycle of first, second periodic electric signal, therefore unique restriction is not done to the relation between the cycle of first, second periodic electric signal and the speed of rotation of stepless knob.
Stepless knob 310 rotates the signal of telecommunication combination first/second round produced exports driver module 320 to testing circuit 321 as command signal, and testing circuit 321 detects the command signal of the generation of stepless knob 310 and exports control circuit 322 to.
Control circuit 322 is according to the circular order of the level state of command signal, judge described command signal be first or second round the signal of telecommunication combination, when described command signal is period 1 signal of telecommunication combination, drive circuit 323 is made to increase power output to light source, when described command signal is signal of telecommunication combination second round, drive circuit 323 is made to reduce power output to light source, and add up the periodicity of described command signal, to determine the speed of rotation of stepless knob 310, and then determine the rate of change of described drive circuit 323 power output.
Particularly, the speed of rotation of control circuit 322 every the default very first time to stepless knob 310 obtains, periodically to determine the rate of change of the power that current driver circuit 323 exports, 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, add up the periodicity of the described command signal that described testing circuit 321 detects within second time of presetting, because the cycle of the command signal of stepless knob 310 generation becomes large with the speed of rotation increase of stepless knob 310, therefore the mechanical periodicity of described command signal within the default very first time can be reflected according to the periodicity of command signal in second time of presetting, and then symbolize the speed of rotation of described stepless knob 310 within the current default very first time.Control circuit 322 is according to the periodicity of the speed of rotation in the described sign current preset very first time and preset the first mapping relations and obtain the rate of change of described power output within the described current default very first time, to regulate the described drive circuit 323 externally power output that provides of light source according to the rate of change of power output 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 second time.
In present embodiment, control circuit 322 preserves the first mapping relations table in electric ballast this locality, such as, described first mapping relations of presetting are specially: when the described described command signal periodicity preset in the second time is less than or equal to default first numerical value, the rate of change of described power output is V
p1; When the described described command signal periodicity preset in the second time is greater than default first numerical value and is less than default second value, the rate of change of described power output is V
p2; When the described described command signal periodicity preset in 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 be sequentially.Certainly, in other embodiments, presetting the first mapping relations can also be at the described rate of change V presetting described command signal periodicity K and power output in the second time
pfor proportional relationship and V
p=K N, wherein, N is a positive count.Further, in other embodiments, at the described rate of change V presetting described command signal periodicity K and power output in the second time
wcan also be set to inversely prroportional relationship, namely within described default second time, described command signal periodicity K is more, and the speed of rotation namely characterizing stepless knob is larger.In addition, first mapping relations are not limited to the mapping relations in default second time between command signal periodicity and power output rate of change, can also be the mapping relations between the cycle size of command signal and power output rate of change, control circuit obtains the cycle size of command signal by the level state 1,2,3,4 detecting 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 any mapping relations of the relation reflected between the rate of change of the stepless knob speed of rotation and power output as the case may be.
For the application's electric ballast is better described, further citing is described, the power that the current externally light source of drive circuit 323 exports is 1000W, now user turns clockwise the rotating mechanism 311 of stepless knob 310, testing circuit 321 detects the command signal that stepless knob 310 produces and exports control circuit 322 to, control circuit 322 judges that the command signal that stepless knob 310 produces is period 1 signal of telecommunication combination, be then defined as increasing power output.Meanwhile, that is control circuit 322 obtains the speed of rotation of stepless knob 310 for 5 seconds every the default very first time.Control circuit 322 first of rotating at stepless knob 310 add up in 5 seconds the second time of wherein presetting that is in 1 second the periodicity K of command signal be 31, according to being pre-stored in the first local mapping relations, during K<=20, the rate of change of power output is V
p1=10W/S; During 20<K<40, the rate of change of described power output is V
p2=20W/S; When K>=40, the rate of change of described power output is V
p3=50W/S, control circuit 322 determines that at first rate of change of power output in 5 seconds be V
p2=20W/S, namely control circuit 322 regulates the power output of drive circuit 323 in 5 seconds with the rate of change of increase per second 20 watts at first, the simultaneously current power output of display module 330 also display driver circuit 323 per second, as first second 1020W, second second 1040W ... 5th second 1100W.Rotate first after 5 seconds at stepless knob 310, the power output of drive circuit 323 is 1000+20*5=1100W.In like manner, at second in 5 seconds, control circuit 322 such as aforesaid way determines the rate of change second power output in 5 seconds, so analogize, until stepless knob 310 stops the rotation, when testing circuit 321 can't detect the command signal of stepless knob 310 rotation generation, the power output that control circuit 322 makes drive circuit 323 keep current.
