Off-grid complementary green smart illumination system

Abstract

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.

Problems solved by technology

At present, there are two main ways to apply solar energy to lighting: one is photovoltaic power generation lighting, and the way of energy conversion is "light-electricity-light". The technology is basically mature, but the energy loss is large and the manufacturing cost is high.

The second is to directly collect sunlight for lighting, which avoids the "light-electricity-light" conversion link and improves efficiency. However, due to the erratic sunlight, the indoor light intensity fluctuates. In addition, sunlight cannot be stored. Unable to solve the problem of weak sunlight or indoor lighting in rainy days and nights

Due to the dependence on mains power, this supplementary light system has the disadvantage of not working without mains power, so it cannot be applied to remote areas without mains power
