Abstract：With the economical development and scientific advance, the buildings equipped with intelligent facility emerge one after another. Building new schoolhouses has become a fever for most schools. Lightening is more important for the intelligent building of school than for commercial building.
This research takes the lightening in school library as the object (square: 12*9 square meters, the regulated working time every day:8:00-22:00). By the comparison with the manually- controlled traditional light, the research puts forward the plan of intelligent lightening control, designs specific examples as well as provides their applications. For the large library with many control points and requirements for a certain lightening, the C-BUS based intelligent lightening control is available as it can automatically adjusts the light to the most ideal level for work, according to different lightening places and zones. For the library in small scale, the PLC based intelligent lightening can be applied to automatically control light, and relatively speaking, it saves the investment in short term. Meanwhile, from the conservation of the energy and according to the lights with varied lightening way in different places, respectively calculating their lightening charges draws a conclusion: intelligent lightening can save electric energy more effectively.
