    • The invention relates to phosphor-conversion (PC) sources of white light, which are composed of at least two groups of emitters, such as blue electroluminescent light-emitting diodes (LEDs) and wide-band (WB) or narrow-band (NB) phosphors that partially absorb and convert the flux generated by the LEDs to other wavelengths, and to improving the quality of the white light emitted by such light sources. In particular, embodiments of the present invention describe new 3-4 component combinations of peak wavelengths and bandwidths for white PC LEDs with partial conversion. These combinations are used to provide spectral power distributions that enable lighting with a considerable portion of a high number of spectrophotometrically calibrated colors rendered almost indistinguishably from a blackbody radiator or daylight illuminant, and which differ from distributions optimized using standard color-rendering assessment procedures based on a small number of test samples.
    • 本发明涉及白光的磷光体转换(PC)源,其由至少两组发射体组成,例如蓝色电致发光发光二极管(LED)和宽带(WB)或窄带(NB) )荧光体,其部分地吸收并将由LED产生的光束转换成其它波长,并且改善由这种光源发射的白光的质量。 具体地,本发明的实施例描述了具有部分转换的白色PC LED的新的峰值波长和带宽的3-4组分组合。 这些组合用于提供光谱功率分布,使光照相当大部分的分光光度学校准颜色与黑体散热器或日光照明器几乎无差别地渲染,并且与使用基于以下的标准显色评估程序优化的分布不同: 少量测试样品。
