Abstract: To improve the control methods and energy-saving effect of apron floodlighting, DIALux software is used to establish a front-type multi-position apron illumination simulation analysis model in this paper. Firstly, by comparing the differences in lighting effects between combinations of two high-mast lights and single-sided lighting, the illuminance compliance rate is introduced as a supplementary basis for lighting evaluation. Then, the control variable method is applied to analyze the parameters of the high-mast light′s elevation angle θT, pointing angle θO and number of lights. The basic process of energy-saving design for floodlighting is illustrated through practical cases. The research results indicate that relying solely on a single high-mast light cannot meet the illumination requirements of Class C parking positions. Using a combination of two high-mast lights for illumination can bal－ ance the needs of illumination, uniformity, and illumination compliance rate. The θT should be≥45° and the θO should not be too large. According to the regulation of a minimum illumination of 10 lx at the apron during nonflight service hours, a multi-base high-mast light combination lighting scheme is proposed for different apron op－ erating states. The general expression and quantitative results of the energy-saving rate of floodlighting are de－ rived, which can provide theoretical guidance and planning suggestions for the design of apron floodlighting com－ binations at new airports and improve the energy-saving level of apron floodlighting.
