Electric Lighting Energy-saving Research Based On Subway Station

In today’s rapid development of human society, as one of quick traffic forms with large volume, the subway has maintained a rapid development momentum. The quantity of subway stations along the line increases gradually, so their lighting power consumption is also increasing. At the same time, most of lighting loads are long-term working loads. It will continue to form large amounts of electric energy loss. If not being controlled, the regional electric power waste caused by it will be considerable. Aimed at the status quo, this article researches electric lighting energy-saving of subway station, aims to analyze power consumption, promote energy-saving measures, realize maximum level of low carbon and environmental protection in lighting system.Through consulting a large number of materials, carefully reading related technical terms, the basic theory of electric lighting which is closely related to lighting energy-saving of subway station is analyzed, with study of practical significance of illumination and LPD, instruction of parameters in illumination calculation formula, influence factors of lighting quality and scientific settings of electric lighting in detail. At the same time, with specific subway station as an example, using the method such as research and analysis, data measurement, scheme comparison, modeling and simulation based on lighting design software DIALux, the effective way of electric lighting energy saving for subway station is discussed, and its application in actual engineering is investigated.Through analysis and research, from perspectives of reasonable selection of light-source and lamps and their attachment, full use of natural light, introduction of intelligent lighting system, scientific light distribution and electric power distribution, the effective energy-saving of the electric lighting system for subway station can be realized.The results of this paper’s research can provide effective measures of subway station electric lighting energy-saving, achieving the reduction of power consumption. On the other hand, as a part of the building lighting energy-saving system, it has certain guiding significance for the study of building lighting energy-saving.
