摘　　要：LED(Light Emitting Diode发光二极管)正在快速进入光源领域,开始逐步取代各类传统光源。采用5W以上的大功率LED构成频闪光源,不仅可以完全替代汞灯频闪光源的功能,而且驱动电路还可以大大简化。它还具有发光效率高、体积小、价格低和使用寿命长等优点,这使频闪光源的应用前景更为广阔。LEDs are rapidly entering the field of lighting, and they begin to gradually replace all types of traditional light source. The stroboscopic light source made of high-power LEDs （higher than 5W） not only can replace the mercury stroboscopic light source, but also can greatly simplify the drive circuit. They have many advantages such as high luminous efficacy, small size, low price, long using life, and so on. In a word, the stroboscopic light source made of high-power LEDs must have a bright future
