摘　　要：脉冲调制的超高亮度白光LED制伏器采用功率型白光LED模组集成化封装并配合高效光学镜头,在频率0～100Hz范围、占空比0～100%可调的脉冲驱动系统的驱动下,来实现满足LED制伏器要求的高功率超高亮度脉冲调制白光LED光源,可以在使用者安全距离以外(5 m以上)远处达到大于105 lx的照度,超过太阳光在地球表面104 lx～105 lx的辐照强度,光斑半径10 cm左右。高亮度光斑配合低于人眼能分辨的频率(25 Hz),能使人眩晕或者暂时失明而失去抵抗力。该系统可实现小型化,作为非致命武器,军用和警用。Super high bright white LED incapacitator,which is driven by pulse modulation system with frequency ranging from 0 to 100 Hz and duty ratio between 0~100%,is realized by integrating a group power white LEDs and efficient lens.The device can produce a light spot with a radius around 10 cm beyond the safe distance（more than 5 m）brighter than 105lx,surpassing 104 lx^105 lx,the light from the sun on the earth.High bright light source glitter at a frequency below 25 Hz,which can be distinguished by human eyes,will make people dizzy or blind temporarily.Thus,this device can be miniaturized as a new weapon to equip the military and police.
