| 摘 要： | 针对当前半导体光源的不稳定性，文章对现有的稳压电源进行改进，推出了一种用于光电实验中驱动半导体光源的高精度驱动电源，驱动电流调节范围为0—100mA，LED数码显示当前电流，电流波动达到极限（最后一位数字跳动1）。采用这种恒流源驱动，直接从驱动源上读取电流值，实验不仅方便直观，并且实验数据的一致性也可以得到保障，从根本上提高了半导体光源的精度和稳定性。

| Abstract: | With regard to instability of semiconductor source, this paper advances a high precision driver for LED or LD used in optoeleetronic experiment for improvement, the driver can provide 0 to 100mA DC, and expressed by a digital LED indicator The noise current is below a digit. This not only makes experiments convenient and direct but also keeps the experiment results stable. Therefore improves fundamentally the precision and stability of semiconductor optical source. |
