Artificial lighting by means of street lights, illuminated buildings, floodlights and neon signs have an effect on humans, animals and plants and too often interfere with the foraging and reproduction of many insects and other species.

Lighting management and intelligent control are important tools for limiting immissions of light and increasing the efficiency of lighting. In a survey conducted by the professional journal Licht“ in August 2021, 24 percent of readers stated that there was a high potential for more sustainability in modern control technology.
