In many lighting applications at the lux level, full coverage of the target surface, uniformity, and glare are important requirements. In the case of LEDs, luminaire optical output depends upon the source of luminous flux, radiation spatial distribution, geometry of the LED array, and source-to-target distance. One has to optimize these parameters to fulfill the needs of the application and to have an efficient LED luminaire. This paper discusses the interdependencies of these parameters. The optimization of a ring LED source configuration is demonstrated for an application of uniform illumination of a plane surface with minimum source flux and with no glare.
在许多勒克斯级别的照明应用中，目标表面的全面覆盖、均匀性和眩光都是重要的要求。对于发光二极管（LED）而言，灯具的光输出取决于光通量的来源、辐射空间分布、LED阵列的几何形状以及光源到目标的距离。必须优化这些参数以满足应用需求并拥有高效的LED灯具。本文讨论了这些参数之间的相互依存关系。针对平面均匀照明应用，在源通量最小且无眩光的情况下，展示了环形LED光源配置的优化。
