Study On Energy Saving Technology Of Building Electrical Lighting

At present, various countries in the world pay particular attention to development andapplication of building energy consumption and energy saving technology. In China buildingenergy consumption is on the increase along with the rapid development of constructionindustry, among which electric lighting energy significantly accounts for14%. Therefore, it’san important way to make full use of energy-saving technology of building lighting forChinese construction industry to develop real low-carbon and green modern buildings.Focusing on reducing energy consumption of building lighting and achieving energysaving, this article’s research content including following several aspects.1. Comb basic concepts of building electric lighting: With the clue of energy-savinglighting, we analyze the characteristics of various electric light sources and the features of fivetypes of luminaries and point out their applications. Secondly, we expound that thecomprehensive evaluation of energy efficiency of electric light is based on two dimensions ofluminous efficiency and lifetime, and higher the value, better the energy efficiency. Then thearticle focuses on the density value of illumination, an important evaluation of energy savingof building lighting, and the value of a room should be less than the required standard. Finally,by in-depth analysis of three kinds of illumination calculation method—utilization factormethod, point-by-point method and unit capacity method, designers are expected to choosethe correct illumination calculation method, complete lighting layout more scientific andachieve reasonable energy saving.2. Systematically study energy-saving technology of building lighting: This is the main partof this article. Building electrical lighting can achieve energy saving in four aspects. The firstis the selection of lighting equipment. We should choose high-efficiency electric light andlamps and energy-saving lighting accessories to make efficient use of energy. The second is toimprove the effect of light distribution. Analyzing the utilization factor method, we canoptimize light distribution and achieve energy-saving lighting through reducing obscurationcoefficient, improving utilization factor of lamps and combining with various lighting formsreasonably. The third is reducing power consumption by adopting advanced intelligent control system of lighting and control technologies of natural light. The fourth is to optimize thepower supply scheme of lighting. By reasonably laying the copper wire, setting the power inthe centers of loads and distributing three-phase load more balanced, the purpose ofenergy-saving lighting can be achieved.3. Construction illumination energy saving case analysis: This is the theory confirmationpart of this article. On the premise of applying electric lighting energy saving technologytheory research of the third chapter, firstly, designing the science and feasible energyconservation illumination plan based on the illumination need of the train station; then givingan example analysis of the new train station illumination design which has verified theelectric lighting energy saving technology theory research of this paper is feasible, and can bepromoted to use.The purpose of this issue research is to reduce energy consumption in the electric lightingsystem as much as possible by application of lighting energy saving technology, and toprovide comfortable and healthy, as well as energy conservation and environmental protectionlighting environment for people in the modern buildings, on the premise of ensuring thenormal operation of buildings.
