The invention discloses an off-grid complementary green smart illumination system, which utilizes sunlight instead of relying on mains supply. During daytime, illumination primarily depends on a sunlight collection and optic fiber introduction illumination sub-system, and when there is insufficient sunlight or it is a rainy day or at night, illumination is supplemented by a photovoltaic off-grid illumination sub-system. The process of supplementary lighting is fully and automatically realized by an automatic light measuring adjustment sub-system so as to achieve a constant indoor illumination. At the same time, an integrated control sub-system monitors the performance parameters of each sub-system at appropriate time in order to provide basis for decision makers to make in-time and accurate decisions. The illumination system herein mainly includes a sunlight collection and optical fiber illumination sub-system 1, a photovoltaic off-grid illumination sub-system 2, an automatic light measuring adjustment sub-system 3, and an integrated control sub-system 4. When there is sufficient sun light intensity outdoor, illumination is provided independently by the sub-system 1, and meanwhile the sub-system 2 implements the function of energy storage. And when there is insufficient sunlight intensity, supplementary lighting is delivered by the sub-system 2. The collection sunlight photovoltaic state parameter of the sub-system 1, the energy storage state parameter of the sub-system 2 and the light measuring and adjustment light state parameters of the sub-system 3 is real-time on-line monitored by the sub-system 4, thus providing a reliable basis for the decision makers.
