LED阵列光源应用于几何光学实验

摘要

A monochromatic and a high power-white light LED array light sources were made,which were used for geometrical optical experiment. For measuring the focal length of lens,LED light sources could be the unifi-cation of both the light source and the object screen. The image effect was better,and the LED light sources were cheap and power-saving.%设计并制作了单色LED、高功率白光LED阵列光源及配套电源，将其应用于普通物理几何光学实验中。在透镜焦距测量实验中，实现了光源和物屏的结合，成像效果好，光源稳定、可调，相比于卤钨灯光源，成本低，且环保、节能，散热小。
