LED ARRAY WITH IMPROVED COLOR AND FLUX CONSISTENCY

摘要

A compound light source and method for making the same are disclosed. The compound light source is constructed from a plurality of component light sources and a method for constructing the same. The compound light source is characterized by an output spectral measure that lies within a spectral measure design range and an average light intensity per component light source that lies within an output intensity design range. The plurality of component light sources includes light source whose spectral measure and output intensity lie outside the ranges. The component light sources are chosen from a number of predetermined groups obtained by sorting the component light sources with respect to the spectral measure and output intensity of each source such that compound light, source has a spectral measure and output intensity that lies within the corresponding design ranges.
