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.
