LED光源在薄透镜焦距测定实验中的应用

摘要

In the thin-lens focal length measurement experiment, after using the improved LED flashlights as the new experimental optical sources, the effect is not only better than that of using the original incandescent light source, but also consistent with energy conservation, environmental protection, and low-carbon economy.%在薄透镜焦距测定实验中,使用改装后的超亮LED(发光二极管)灯作为新的实验用光源,不仅实验效果明显优于原有白炽灯光源,而且符合节能、环保,低碳经济的要求.
