| 摘 要： | 以发光二极管(LED)为核心的半导体照明光源成为世界公认的第三代照明光源.通常基于蓝光LED抽运黄色荧光粉产生白光的方案,因荧光粉的斯托克斯位移和宽光谱,其具有产业化价值的发光效率上升范围受到极大限制.另外,传统封装LED因其朗伯型发光分布和超高亮度会造成严重的眩光以及光分布难以满足照明应用要求从而导致光污染、光浪费,...

| Abstract: | Solid state lighting sources based on white light emitting diodes(LEDs) are considered as the third generation lighting sources.Generally,white light is generated by combination of the blue LEDs and yellow phosphor with the Stokes shift and wide-band emission(PC LEDs),which limits the maximum luminous efficacy with industrialization value.In addition,traditional packaged LEDs cannot be directly used in lighting with high efficiency,perfect lighting effect and low glare because of their Lambertian radiation ... |
