摘要： Embodiments of the present invention are directed toward white light illumination systems (so called "white LEDs") that comprise a multi-chip excitation source and a phosphor package. In a two-chip source, the two LEDs may be UV-emitting and blue emitting, or blue-emitting and green-emitting. The phosphor package is configured to emit photoluminescence in wavelengths ranging from about 440 nm to about 700 nm upon co-excitation from the first and second radiation sources. The photoluminescence emitted by the phosphors is at least 40 percent of the total power in the white light illumination, and the portion of the total power in the white light illumination contributed by the first and second radiation sources (LEDs) is less than about 60 percent. This ratio can vary in alternative embodiments, and includes 50/50, 60/40, 70/30, and 80/20, respectively. The white light illumination emitted by the system has in one embodiment a color rendering index (CRI) greater than about 90.

摘要翻译：本发明的实施例针对包括多芯片激励源和磷光体封装的白光照明系统（所谓的“白色LED”）。在双芯片源中，两个LED可以是紫外发射和蓝色发射，或蓝色发射和绿色发射。磷光体封装被配置为在从第一和第二辐射源共同激发时发射范围从约440nm到约700nm的波长的光致发光。由荧光体发射的光致发光是白光照明中总功率的至少40％，并且由第一和第二辐射源（LED）贡献的白光照明中的总功率部分小于约60％。该比率可以在替代实施例中变化，并且分别包括50 / 50,60 / 40,70 / 30和80/20。在一个实施例中，由系统发射的白光照明具有大于约90的显色指数（CRI）。
