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.
