Because the power and the electric current of the laser instrument in the laser beautifying machine are non-linear relations, the power that the power ratio that hour goes out at electric current goes out when electric current is big is little.Before the present invention made, laser instrument bright dipping principle as shown in Figure 1.Electronic control circuit is according to setting power, by fixed dutycycle, goes out a pulse current and is added to laser controller, opens laser signal if laser controller is received electronic control circuit, just instructs the laser instrument bright dipping, wholely goes out photoreduction process and finishes.This by fixed dutycycle, go out the method that a pulse current is added to laser controller, lasing efficiency is not high, and laser instrument not necessarily is operated in optimum state.
Summary of the invention
The purpose of this invention is to provide a kind of can the change dutycycle of pulsating current, thereby make laser instrument be operated in the control system of the laser efficiency of laser beautifying machine of optimum state at any time according to setting power; Purpose of the present invention also provides the control method of the control system of laser efficiency of laser beautifying machine.
In order to achieve the above object, the present invention has following technical scheme:
The control system of a kind of laser efficiency of laser beautifying machine of the present invention, comprise laser controller, the laser instrument that is connected with laser controller, the microprocessor that also comprises the electric current occupancy controller, is used to control the electric current dutycycle and sends switching signal, wherein, microprocessor is connected with laser controller, electric current occupancy controller respectively.
The control method of the control system of a kind of laser efficiency of laser beautifying machine of the present invention has following steps:
1) according to laser instrument bright dipping needs pulse current, microprocessor internal stores best power and pulse current dutycycle correspondence table;
2) microprocessor draws the pulse current dutycycle according to the power method of tabling look-up that the user sets;
3) utilize microprocessor internal PWM Modulation Pulse Current to the electric current occupancy controller, the electric current occupancy controller changes the pulse current dutycycle according to microprocessor signals, and the output pulse current obtains driving signal;
4) the electric current occupancy controller is given laser controller this pulse current then, and simultaneously, microprocessor sends switching signal and gives laser controller, and laser controller goes out laser to signal laser.
Owing to taked above technical scheme, the invention has the advantages that:
(1) with original laser beautifying machine ratio, improved efficient with the control system of laser optimum efficiency of the present invention, saved the energy, and guaranteed to make laser instrument be operated in the state of optimum efficiency at any time.(2) because with under the constant power, electric current is little, thus improved laser life-span, thus improved the economic benefit of user.
