Modelling of lighting in urban parks for investigation of environmental impacts

The urban parks are representing the nature in urban space. Residents visit these parks for the purpose of relaxation, recreation, or free time activities. Urban parks help them with enjoying this time with their content like trees or bushes that provide shade, grass areas, flowers or small animals which take place in these parks. At night, these parks are illuminated and often the lighting can not only illuminate benches or sidewalks, but also the whole trees and other parts of park. Does this light have an environmental impact on the urban park? By modelling the lighting in urban parks, we can simulate situations in which we illuminate directly content of a park, like trees. By creating multiple simulations, we can choose which kind of lights and their light sources, and which kind of overall light system, have a greater or lesser impact on the urban park.
