摘要： 照明工程质量是隧道照明领域研究的重点之一。考虑人眼视网膜不同区域分辨能力的差异性，利用室内隧道缩尺模型，根据不同视觉范围划分测点区域，测量各测点处的目标亮度和背景亮度，修正并计算STV值，得到中央逆光照明参数对不同视觉范围内的STV值的影响规律。结果表明：①逆光照明角度30°时，中央视觉和周边视觉下的STV值都最大；②随着布灯间距增大，中央视觉下的STV值先增后减，周边视觉下的STV值逐渐减小；③高漫反射率侧壁材料略比瓷砖侧壁下的STV值小；④中央视觉范围比周边视觉范围内的视看环境好，提高周边视觉下的可见度水平具有重要作用。提出了小目标可见度的修正模型，为隧道照明质量设计和评价提供了新思路。

Abstract: The quality of lighting engineering is one of the focuses of the research in the field of tunnel lighting. Considering the differences in the resolving power of different regions of the human retina, the scale model of indoor tunnel was used to divide the measuring point area according to different visual ranges. The target brightness and background brightness at each measuring point were measured, and the STV value was corrected and calculated. The influence of central backlight illumination parameters on STV values in different visual ranges was obtained. The results show that: ① When the backlighting angle is 30°, the STV value both under foveal vision and peripheral vision is the largest; ② As the distance between lights increases, the STV value in the foveal vision first increases and then decreases, while the STV value in the peripheral vision gradually decreases; ③ The high diffuse reflectivity sidewall material slightly lowers the STV value, compared with the tile; ④The visual environment under foveal vision is better than that under peripheral vision, and it plays an important role in improving the visibility level of peripheral vision. The modified model of the visibility of small target was proposed, which provided a new idea for the design and evaluation of tunnel lighting quality.
