The urban leisure plaza is mainly dominated by lawns, generally decorated with various flowers and trees or with rockeries, pools, paths, sculptures and other shapes, creating a flourishing natural taste. Such squares are important behavioral places for residents' urban life, including garden squares, cultural squares, water squares, and public activity spaces set up in front of residential areas and public buildings. The buildings and environmental facilities of the square are required to have high artistic value.
The lighting design of the urban leisure plaza should be suitable for the physiological requirements, safety requirements and communication requirements of tourists. This type of square is mainly located in the commercial downtown area or urban residential area. The function is mainly to facilitate people to rest and entertain. The facilities are relatively complex, such as houses, frame structures, corridors, scaffolding, rockeries, pools, fountains , flower ponds, green spaces, sports and leisure facilities, stone benches, etc. Therefore, the lighting design of urban leisure plazas should meet the following requirements:
(1) Make people feel relaxed, comfortable and casual, and can concentrate on the place to avoid uncomfortable glare.
(2) Meet the requirements for detecting obstacles.
(3) Satisfying the brightness of the visual orientation, the illumination of the signs and signs in the square can be slightly increased to help people who are not familiar with the surrounding environment to determine the direction.
(4) From the perspective of safety and communication, it is necessary to ensure that the face of others or the characteristics of others can be recognized within a range of about 10m.
