摘　　要：物理实验中使用的光源通常有白炽灯、纳光灯、低压汞灯和氦氖激光器等，它们统属于气体光源。近年来，LED、LD构成的半导体光源，在各个领域被广泛应用。笔者对LED、LD光源在物理实验中取代传统的气体光源进行探索和尝试，并取得有益的经验。实践证明，由于LED、LD光源构造的特殊性，实验效果往往更优于气体光源。The lamp-house of the mercurial lamp and He-Ne laser. physics experimentation includes incandescent lamp, sodium lamp, Due to LED, LD＇ s technology has progressed, the scopes of lamphouse are taking place are taking place a huge change. LED, LD＇ s lamp-house has entered into market of experiment for high illuminant efficiency, small volume, long life and low price, it will replace traditional lamp-house. The article introduce characteristic of Semiconductor lamp-house, and then we discuss the application in experiment scopes.
