The semiconductor switch has the problem of service life and failure. Once the pulse controls the semiconductor switch element to pass through, all the energy stored in the high-voltage energy storage capacitor group will be released through the flash lamp. Due to the huge energy, it greatly exceeds the stress it can withstand, and the light emits maximum energy. The strong light will burn the skin of the human body and even explode and harm the human body. Therefore, the existing intense pulsed light generating device for medical cosmetology is not safe enough.

After adjusting to a suitable voltage, the CPU computer control module sends a trigger to the trigger. The signal causes the second energy storage capacitor group to discharge through the flash lamp.

所述的触发器为内触发。The trigger is an internal trigger.

所述的升压模块、储能电容组、触发器、隔离变压模块、第二储能电容组、电压检测模块和反馈电压调节模块各有两套,分别接受CPU计算机控制模块的控制。There are two sets of the boosting module, energy storage capacitor group, trigger, isolation transformer module, second energy storage capacitor group, voltage detection module and feedback voltage adjustment module, respectively, which are controlled by the CPU computer control module.

所述的闪光灯由两个串连并排排列的灯管组成。The flashlight is composed of two lamp tubes arranged side by side in series.

在采用了上述技术方案后,由于去掉了脉冲控制开关,能量来源取决于第二储能电容组的电容容量及充电电压的高低,而第二储能电容组的电容容量是固定的,因此输出能量取决于充电电压,而充电电压是取自于能量控制库内的已经设定的安全电压,从而使释放出的能量受限于安全能量内,解决了现有的医疗美容用强脉冲光发生装置不够安全的技术问题。After adopting the above technical scheme, since the pulse control switch is removed, the energy source depends on the capacity of the second energy storage capacitor group and the level of charging voltage, and the capacity of the second energy storage capacitor group is fixed, so the output The energy depends on the charging voltage, and the charging voltage is taken from the safety voltage that has been set in the energy control library, so that the released energy is limited to the safe energy, which solves the problem of the current generation of intense pulsed light for medical cosmetology. Technical problems with insufficient security of the device.
