Light pollution involves the usage of sources of artificial lights for brightening the night sky, which is scattered into the environment. Artificial lighting is possibly the greatest success of humans and has to turn out to be an essential part of the urban surroundings [1,2]. Light pollution has been considered to be the most speedily growing variation to the surroundings. It was supposed that artificial light offers security and enhances visibility but a large section of lighting does neither. Lighting which is overused, misdirected, or else conspicuous is mainly pollution. Artificial lighting is considered to be the latest form of pollution. So, this issue is attracting extensive attention. During the last few decades, fast industrialization and urbanization lead to the extensive usage of artificial light. This has significantly altered the nightscapes, although their harmful impacts are over and over again ignored.

Another SLS application area discussed in the literature can generally be defined as outdoor illumination, where a strong focus has been directed towards street lighting. By considering different weather and external light conditions as well as reflective properties of road surfaces and surroundings, light quality and visibility are two of the most important factors in street lighting research. In addition to external factors, the correct selection of lighting components, such as luminaires, in combination with factors such as light spot mounting height, optimal luminaire spacing, and road surface properties is important (Yoomak and Ngaopitakkul 2018; Markvica, Richter, and Lenz 2019). Lighting systems can adapt the illumination level to provide better overall visual and comfort performance based on current conditions. By considering these external factors, adjustments enable energy savings (Abdullah et al. 2019). Furthermore, energy consumption can be reduced by turning street lamps on when motion is detected. Sensor-based lighting systems are, therefore, able to save energy and adjust the brightness automatically to the given conditions (Maithili et al. 2017). Another benefit of light reduction includes reduced light pollution, which makes an important contribution to ecological sustainability (Gutierrez-Escolar et al. 2017).

The National Lighting Product Information Program is more specific and defines light pollution as an unwanted consequence of outdoor lighting and includes effects such as sky glow, light trespass, and glare (Lighting Research Center 2007). Some national regulations as in Spain (Ministry of Industry, Tourism and Trade of Spain 2008) or state laws in the United States (Schultz 2016) are more in line with those of the Lighting Research Center.
