White LED-based Solid State Lighting Using Phosphors as Spectral Converters

Keywords： white LED , colorimetry , luminescence physics , phosphors , rare earths

近20年来,基于荧光粉光转换的固态照明技术得到了迅速发展.本文试图从一些常见的概念出发,对照明光的评价标准、荧光粉的发光物理,以及光转换设计这几方面进行简要的阐述.这些相关知识的理解无疑会促进白光LED的研发和进一步推广.

Since the mid-1990s,phosphors have played a key role in the emerging solid state lighting field.This paper presents a brief review on several key aspects,involving the evaluation criterion of general illumination quantify,the basic knowledge of luminescence physics in phosphors,and the approaches to design phosphor-converted white LED (light-emitting diodes).Further understanding of these key aspects will certainly promote the research and development of white LED illumination.
