摘要
通过在实验室建立大自然的雾霾模拟环境,本文研究了在雾(液态)和霾(固态)环境下,LED灯具、金卤灯以及钠灯三种典型户外光源灯具的透射率,从而得出在不同浓度的雾以及不同程度的霾中各种光源的穿透性,对道路照明设计有一定的参考价值。
With the rapid development of industrialization,pollutant from industry and automobile has a big influence on the air quality of cities. With the high humidity caused by the urban microclimate,the visibility is greatly reduced due to the hazy weather formed by the accumulation of pollutant and vapor. In this paper,a hazy simulation environment is established to measure the transmittance of LED lamps,metal halide lamps and sodium lamps. First,we studied their transmittance under the fog condition（ liquid） as well as the haze condition（ solid）. Then,the comparison among transmittance of light sources under different hazy environment is shown. The results are useful to the road lighting design.
