基于辨识效果的地下车库照明质量评价指标研究

为了保证在地下车库光环境中快速识别他人行为并做出反应,提高使用者的舒适感与安全感,针对目前车库照明标准中评价指标的不足,采用实测与主观评价相结合的实验方法,对重庆大学B区地下车库光环境进行了调研。对实测数据与评价结果进行分析,运用Facereader软件进行验证,参考国内外室外照明相关标准值,从辨识行人效果的角度,提出了半柱面照度是评价车库照明质量的重要指标,完善了立体感评价指标的适用范围,建议地下车库设计中应考虑半柱面照度与立体感指标,且半柱面照度应不小于6.5 lx,立体感指标应不小于0.75的标准值,以达到基于舒适感与安全感的防侵犯照明。该研究成果也对类似的昏暗室内公共空间的照明质量评价具有重要的借鉴意义。

Research on quality evaluation index of underground garage lighting based on identification

In order to ensure the rapid recognition of other people''s behaviors in underground garage and to improve user''s sense of security and comfort, the experimental methods combining actual measurement and subjective evaluation are adopted for the inadequacies of the evaluation indicators in the current garage lighting standards and to investigate the light environment of the underground garage in Area B of Chongqing University. By analyzing measured data and evaluation results, Facereader software is used for verification. With referring to the standard values of outdoor lighting, from the perspective of identifying other people actions, it''s presented semi-cylindrical illumination is a main indicator for evaluating garage lighting, and the scope of application of stereoscopic indicators is summarized. It is suggested that the semi-cylindrical illumination and stereoscopic indicators should be considered in the design of underground garage. The scope of application of the index suggests that the underground garage semi-cylindrical illumination should be no less than 6.5 lx, and the stereoscopic indicator should be no less 0.75 to achieve safe anti-infringement lighting. The research also haves important reference significance for the evaluation of lighting quality in similar dark indoor public spaces.
