摘要：
Color uniformity over a wide range of viewing positions for mid-power packages is achieved by adjusting the configuration (804d) of LEDs within a given LED package (812). In particular, the LEDs (802) within a given package can be configured such that the area (829) occupied by LEDs when the packages are superimposed is substantially larger than the area (831) of the superimposition that is unoccupied by the LEDs to significantly enhance the color uniformity of the system. In addition, the LED dies or chips within a given LED package can also be arranged asymmetrically to improve the color uniformity of the system.
摘要（中）：
通过调整给定LED封装（812）内的LED的配置（804d）可实现中功率封装的宽范围的观察位置的颜色均匀性。 特别地，给定封装内的LED（802）可被配置为使得当封装叠加时由LED占据的区域（829）基本上大于由LED未占据的重叠区域（831） 增强系统的颜色均匀性。 此外，LED管芯或给定LED封装中的芯片也可以不对称地布置以改善系统的颜色均匀性。
