The Intelligent Lighting Control Model Reserch Based On Architectural Light Environment

With the increasing acceleration of urbanization, architectural light environment is demanding higher and higher, and building energy consumption is also increasing day by day. Our lighting electricity accounts for about 20% of the total electricity in the whole society, and for a long time,intelligent lighting combined with natural lighting has been ignored in the domestic, most of the building lighting still use manual control mode. Therefore, reasonable and effective use of natural light to reduce the lighting electricity consumption, and implement green lighting is an important way to achieve energy conservation.In view of this circumstance, this topic is about the research of building light environment. First of all, the building light environment including the research and analysis of natural light environment and artificial light environment, and proposed the full use of natural lighting and artificial lighting with the combined strategies to meet the needs of building light environment.Second using Ecotect software established the research object, studied the ability of its natural daylight, mainly analyzes the orientation, size, window wall and other factors of different season which affect natural lighting, then simulate the daylight of the different seasons of the research object, and combined with different ways of artificial lighting and give the analysis results.Finally on the basis of the existing intelligent lighting control system, in view of the natural lighting model characteristics such as accuracy, coupling, nonlinear, using the fuzzy control combined with particle swarm optimization(PSO) algorithm to model, with natural lighting and illumination difference in the value is converted to the corresponding voltage value as input, the voltage of artificial light adjustment, to artificial light source output voltage and the adjustment of the shutter as the output model.So it will realize intelligent control of interior lighting environment on the premiseof adapting the human rhythm according to interior natural lighting level.Fuzzy theory is used to model, and control the lights output and shutter automatically based on the interior illuminance level in a typical office room. Demonstrated by MATLAB simulation results,this method Can save energy significantly,and improve working environment and efficiency.
