Embodiment
Below in conjunction with accompanying drawing execution mode of the present invention is done further explanation.
As shown in Figure 2, present embodiment provides a kind of method through button execution brightness regulation, and this method is based on sending the brightness that the signal of controlling light-source brightness is controlled light source through control unit to drive circuit, and specifically this method comprises:
A. at first, the brightness of control unit control Driver Circuit driving light source is by secretly gradually changing to bright, after the maximum that arrives brightness, again by bright to secretly gradually changing.Be specially: in control unit, solidify a program, the corresponding driving light source of this program according to earlier by secretly gradually to bright, and then by the bright control signal that changes to dark state work gradually; Opening the switch of control Driver Circuit break-make first, make controller start working, the drive circuit conducting; Control unit control light source driving circuit driving light source is according to by secretly gradually to bright; And then change to dark state work gradually by bright, before switch broke off, said light source was still according to the variation that moves in circles of above-mentioned order; When switch breaks off, stop to change.Said control signal is a pwm control signal.
B. judge whether control unit receives by the detected low level input of testing circuit, if, execution in step C; If not, then control unit continue the brightness of control Driver Circuit driving light source by secretly to bright or by bright to secretly gradually changing;
C. when detecting the low level input, of short duration power supply circuits continue to the control unit power supply, and control unit will be kept in the volatile memory cell with the corresponding luminance state information of current light source brightness; Judge whether control unit receives by the detected high level input of testing circuit; If then continue to judge the luminance state information of in volatile memory cell, whether preserving; If do not preserve luminance state information, then control unit continue the brightness of control Driver Circuit driving light source by secretly to bright or by bright to secretly gradually changing, and return step B; If preserve luminance state information, then execution in step D; If control unit does not receive by the detected high level input of testing circuit, then execution in step F;
D. control unit control Driver Circuit driving light source is according to the corresponding brightness work of the luminance state information of being preserved; Judge that whether control unit receives by the detected low level input of testing circuit, if there is not the low level input, then continues the control Driver Circuit driving light source according to the corresponding brightness work of the luminance state information of being preserved; If the low level input is arranged, then control unit is removed and is kept at the luminance state information in the volatile memory cell, execution in step E;
E. judge whether control unit receives by the detected high level input of testing circuit, if do not have low level input, then execution in step F; If the low level input is arranged, then returns execution in step A;
F. carry out and wait for cyclic program, end;
Be specially: when in light source works during at the described state of A step; Cut-off switch, then drive circuit and control unit have lost the power supply that is provided by switch, but of short duration power supply circuits continue as control unit electric energy are provided; Continue Drive and Control Circuit work; Control circuit obtains the make-and-break signal of switch through the voltage signal of the detected switching circuit of testing circuit, and after control circuit knew that switch breaks off, control circuit obtained switching circuit from being conducting to the time of breaking off operation; And from program curing, find out the light-source brightness state information of switch-off instant according to this time, and with this luminance state information stores in the volatile memory cell of control unit.Of short duration power supply circuits can offer and decide discharge time of energy-storage travelling wave tube of the of short duration power supply circuits of basis of time of control circuit electric weight, and this energy-storage travelling wave tube can be inductance, electric capacity or battery.
After control circuit gets up the luminance state information stores; Just waiting for the closed once more of switch; If it is closed to have consumed the back at of short duration power supply circuits electric weight; Then the luminance state information of storage disappears, and will return steps A so, and control circuit control Driver Circuit driving light source is according to the described state variation of steps A.If the luminance state information of storage has not existed, this is illustrated in does not have switch closure before of short duration power supply circuits electric weight exhausts, then control unit continue the brightness of control Driver Circuit driving light source by secretly to bright or by bright to secretly gradually changing; If control unit does not receive by the detected high level input of testing circuit, wait for that then of short duration power supply circuits electric weight exhausts the finishing control flow process; If exhaust preceding closure at of short duration power supply circuits electric weight, then the luminance state information of storage still exists, and then control circuit control Driver Circuit driving light source is according to the corresponding brightness work of the luminance state information of being preserved.
Next, judge that whether control unit receives by the detected low level input of testing circuit, if there is not the low level input, then continues the control Driver Circuit driving light source according to the corresponding brightness work of the luminance state information of being preserved; If the low level input is arranged; Then control unit is removed and is kept at the luminance state information in the volatile memory cell, judges whether control unit receives by the detected high level input of testing circuit, if there is not the low level input; Wait for that then of short duration power supply circuits electric weight exhausts the finishing control flow process; If the low level input is arranged, then returns execution in step A;
So the advantage of design is, if people have missed optimal brightness when selecting brightness, can also switch turned off and opens rapidly, reselects, and need not to wait for, has improved the convenience of light modulation.
Need to prove: after switch broke off, drive circuit broke off, and stops to light source power supply; Because each light modulation all need be broken off switch, make light source all stop power supply, if light source does not have other power supply circuits that it is supplied power; Light source is extinguished; If light source is extinguished at every turn, make troubles then can for work and life, and frequent increasing along with the switch number of times; Will certainly reduce greatly the useful life of light source, so need the design energy-storage travelling wave tube to break off the back at switch light source carried out of short duration power supply.As shown in Figure 1; Comprise of short duration power supply circuits in the device, comprise electrochemical capacitor, be connected with drive circuit with control unit; Under off-position, can in a period of time, keep the data in the volatile memory cell in the control unit for control unit and the of short duration power supply of drive circuit; Behind switch closure, again of short duration power supply circuits are charged, more excellent energy-storage travelling wave tube is electric capacity or inductance.Owing to designed of short duration power supply circuits light source is continued power supply; Even make the moment of light source at cut-off switch; Also continue the same brightness of maintenance, promptly the electric current of light source and magnitude of voltage remain unchanged, so be in light and shade graded state and break off moment at drive circuit at light source; The electric current of drive circuit output was or/and magnitude of voltage when control circuit can obtain the drive circuit disconnection; Described electric current is or/and the luminance state of the light source that magnitude of voltage is corresponding drive circuit when breaking off or/and magnitude of voltage temporarily stores, promptly has been equivalent to store the light-source brightness state information when drive circuit breaks off with this electric current.
The circuit structure of of short duration power supply circuits is as shown in Figure 3, comprises 100 Europe resistance R 1, the resistance R 2 in 220K Europe, and the resistance R 3 in 30K Europe, the electrochemical capacitor C2 of 0.47uF has illustrated the annexation of each element among Fig. 3.The power-on time of of short duration power supply circuits has different designs according to concrete condition, and scope is probably about 2 to 10 seconds.
As shown in Figure 1, also comprised testing circuit in the device, the circuit structure of testing circuit is as shown in Figure 4; Testing circuit is by capacitor C 1, C2, and diode D and resistance R 1, R2 form, wherein; The end ground connection of C1 and C2; The other end of C2 is connected with the positive pole of diode D, is connected with resistance R 1 between the negative pole of the other end of C1 and diode D, and the two ends of C1 are parallel with resistance R 2; Capacitor C 1 is connected with control unit with the public connecting end of resistance R 1, and capacitor C 2 is connected with switch with the link of diode D negative pole.
