摘要： A red phosphor of the present invention is excellent in absorption in blue region and has wide emission spectrums in order to be applied in blue LED chips and can make high quality white light with high color rendering when the red phosphor is mixed with green phosphor. In addition, the red phosphor has approximately 400-500K of CCT (Correlated Color Temperature) so that the red phosphor can make warmer white light than blue LED / yellow phosphor based white light device. Thus, the application of EuSi2O2N2 red phosphor in white light device solves weakness of low color rendering of the blue LED / yellow phosphor based white light and prepares to have competitiveness by processing low price mass production.
摘要翻译：本发明的红色荧光体在蓝色区域的吸收性优异，并且具有宽的发光光谱，以便应用于蓝色LED芯片中，并且当红色荧光体与绿色荧光体混合时可以制造具有高显色性的高品质白色光。此外，红色荧光体具有大约400-500K的CCT（相关色温），使得红色荧光体可以比蓝色LED /黄色荧光体基白光装置更暖白光。因此，EuSi2O2N2红色荧光粉在白光装置中的应用解决了蓝色LED /黄色荧光粉基白光的低色彩缺陷，并通过加工低价批量生产准备了竞争力。
