Fault Tolerant Control of Large LED Systems,solid-state lighting (SSL) systems. A failed LED may significantly reduce the overall illumination level, and destroy the uniform illumination distribution achieved by a nominal system. The main challenge in diagnosing LED degradations lies in the usually unsatisfactory observability in a large LED
