查询词典 led

My first idea is making LED to work like a frequency strobe, so the output capacity is removed in the first schematic. Unfortunately it won't work, or I can say it works but not usable. The LED is half brightness in this situation.

其实要让这个电路运作并不一定需要这个稳压电容，原本也希望将它移除让LED以频闪方式运作，但不知是频率太高还是Duty Cycle太短，这种情况下LED亮度大约会减少一半，没有实用价值。
