Development of Warm White LED on Near UV LED Excitation Phosphor [PDF]
, 2016 由于白光LED具有节能、减排等诸多优点，白光LED固态照明是目前各个国家和地区都在积极推动的技术和产业。但常规的白光LED光谱偏离太阳光谱，损伤人眼，不适合于室内照明。采用近紫外光激发三基色荧光粉制备暖白光LED是解决本难题的最佳方案。与蓝光LED激发荧光粉制作白光LED技术方案相比，采用紫外或近紫外LED激发三基色荧光粉制作的暖白光LED，其发光光谱的质量只与荧光粉配比相关，紫外LED本身不参与可见光光谱的发光，因此白光光谱的均匀性和一致性可以得到保证 ...
