In the traditional system of intelligent building, including integrated wiring, computer network, security, building automation system and other subsystems. But in recent years, with the development of economy and the progress of science and technology, people have put forward higher requirements to the energy saving and scientific management of the lighting lamps. In the building boom, the builders are aware of the importance of intelligent lighting. The use of lighting control system, but also reflects its advantages in energy saving and management, improve the scientific management level of building blocks. Energy saving is the biggest advantage of the lighting control system. After the intelligent lighting control system, we can according to the different situations, different people flow, for the time, the work mode of the subdivision, the unnecessary lighting to turn off, when the need to automatically open. At the same time, the system can make full use of natural light, automatically adjust the indoor illumination. Control system to achieve a variety of different working conditions of the work mode, in order to ensure the necessary lighting at the same time, effectively reduce the work time of the lamps, save the unnecessary energy expenses, but also to extend the lamp life. Paper. A good working environment is a necessary condition for improving work efficiency. Reasonable selection of light source, lamps and lighting control system performance, can improve the quality of lighting. Intelligent lighting control system has two kinds of control method of switch and dimming. It can effectively control the average illumination value of all kinds of illumination, so as to improve the uniformity of illumination. At the same time, the system can according to different time periods, peoples different needs, automatic adjustment of
