摘要
LED发光亮度由驱动电流决定,驱动电流稳定与否直接影响LED发光亮度,本文通过设计一种基于单片机数字控制的驱动电路,经试验证明,该电路使用可靠,并给出了具体的试验波形。
Light-output of LED is decided by driving current. The stability of driving current has directly influence on light-output. In this paper, a digital controlling circuit in designed based on a micro-chips. It is proved stable by test. The experimental waveform is also given.
