全光谱LED具有光谱和太阳光可见光光谱相似度高、色彩饱和度和保真度高、显色指数接近100且无蓝光危害等优点,被认为是未来半导体照明技术的一个主流方向。本文从全光谱LED的概念和特性着手,简述了全光谱LED方案相较于传统方案的优越性;阐述了目前主流的全光谱LED方案及存在的问题;最后,分别从新型荧光粉的开发和多基色全光谱的合成两个方面介绍了研究者们关于完善光谱和简化流程所做的工作,并对未来全光谱LED的应用做出了设想。
Full-spectrum LED has the advantages of high spectral similarity with the visible spectrum of sunlight
high color saturation and fidelity
close to 100 color rendering index and no blue light hazard
and is considered as a mainstream direction of semiconductor lighting technology in the future. Starting from the concept and characteristics of full-spectrum LED
this paper describes the advantages of full-spectrum LED scheme compared with the traditional scheme. The mainstream full-spectrum LED schemes and existing problems are described. Finally
the work done by the researchers in perfecting the spectrum and simplifying the process is introduced from two aspects of the development of new phosphors and the synthesis of multi-color full spectrum. And the application of full spectrum LED in the future is envisaged.
