室外照明可能是光污染这一不良现象的根源。过多的光污染会产生后果：它会冲淡夜空中的星光，干扰天文研究，破坏生态系统，对健康产生不利影响，最后浪费能源。光污染的大小主要取决于光源的类型（光谱功率分布）和灯具强度分布曲线。还有其周围表面的位置和反射特性，例如建筑物的墙壁、沥青、草地等都很重要。本文对公园巷弄光污染量的描述因素进行了分析。公园路径的模型由专业照明设计软件完成，其中有树木、灌木、长凳和草地路径，由此类应用中使用的典型照明灯具进行照明。对用于给定公园小巷照明的蛋白石球型灯具中使用的 MH、HPS、LED 暖光灯和 LED 冷光灯进行了光污染系数的计算。考虑了景观色彩的季节变化和季节性植被的数量。根据我们的计算，景观区域的光污染量与一年中的季节有很强的相关性。此外，每个季节的这种效果取决于灯的类型。
Outdoor lighting can be a source of undesirable phenomena known as light pollution. Too much of light pollution has consequences: it washes out starlight in the night sky, interferes with astronomical research, disrupts ecosystems, has adverse health effects and finally energy is wasted. The amount of light pollution mostly depends on the type of light source (it's spectral power distribution) and the luminaire intensity distribution curve. Also the placement and the reflective properties of the surface around it e.g. the walls of buildings, asphalt, grass, etc. are important. In this paper the analysis of factors describing amount of light pollution in the park alleys was carried out. The model of park path, with trees, shrubs, benches and grassy paths, illuminated by typical lighting luminaires, used in such applications, was done by professional lighting design software. Computations of light pollutions factors were done for MH, HPS, LED warm light and LED cold light lamps used in opal sphere type luminaires, used for the lighting of given park alley. The seasonal variation of landscape color and the amount of seasonal vegetation was taken under consideration. According to our calculations the amount of light pollution in landscape areas has a strong correlation with the season of the year. Additionally this effect, for each season, depends on the lamp's type.
