Study On The Measures To Improve The Quality Of Lighting In Building Electrical System

As an important part of the building electrical system, lighting engineering plays an important role in the full playing functions of architecture. With the improvement of economic level and electrical lighting technology, people’s requirements of building electrical lighting quality are also getting higher and higher. Improving lighting quality is not only to meet the needs of visual work, improving people’s work and study efficiency, but also to provide people with a comfortable lighting environment, which is conducive to people’s physical and mental health.In order to achieve good lighting effect, in this paper, improving the lighting quality of building electrical system as the subject, the main research contents include the following aspects:(1)Combing the basic theory of electrical lighting technology and lighting quality. Firstly, the theory of the measurement of the light in the electric lighting is analyzed, which lays the foundation for the evaluation of the quality of lighting; Secondly, analyzes the elements of lighting quality evaluation, high quality lighting must meet the environmental impact of lighting quality elements needs; Then, the types of electric light source and the characteristics of different electric light sources are introduced; Finally, the effects of voltage deviation, voltage fluctuation and flicker, inter harmonics on the quality of lighting are analyzed.(2)The measures to improve lighting quality in building electrical design are studied, including five parts: firstly, reasonable application of light sources and lamps. Different light sources can meet the different needs of different environments for light, lamps can control the distribution of light in space, suitable lighting accessories can ensure the output of light stability. Secondly, ensure the quality of the lighting layout design. According to different lighting functions to select different lighting methods, as well as the appropriate lighting layout; Thirdly, choose the best control methods. Including manual control, automatic control and intelligent control, to provide efficient, convenient and comfortable lighting experience; Fourthly, the use of natural light. Human is from nature, the sunlight is the best light source, while combing the natural lighting and the artificial lighting, to provide a good lighting environment; Fifthly, through the optimization of lighting power supply design, reactive power compensation and harmonic control, reduce the impact of power quality on the lighting, to improve the quality of lighting.(3) The case analysis of improving the quality of Library lighting, combining theory with practice. According to the needs of the library lighting, take the measures of improving the lighting quality in the third chapter as the basis to analyse the design of the lighting of the library. Through the lighting software DIALux simulation, providing a better alternative for the library lighting.Through the research and case analysis of this topic, applying improving lighting quality measures to each link of the lighting design, and combining the idea of green lighting with improving lighting quality measures, to create a good lighting quality of modern lighting.
