模拟雾环境下视觉可见度实验研究

摘要

In the hazy weather , the real illuminance generated by outdoor lighting facilities is much lower than the theoretical value.Thus, it’s necessary for us to conduct researches on how does fog influence human’ s visibility.The experiment builds artificial fog in laboratory and researchers try to find the relationship between fog density and visibility .%各类室外照明设施在雾霾等恶劣气象条件下，实际产生的照度值可能远低于理论计算值。为确保实际照明效果满足相关标准的要求，有必要开展恶劣气象条件下目标可见度的相关研究。本文在实验室条件下人工造雾，研究不同雾浓度下视觉可见度的下降情况，从而为道路照明设计提供参考。
