The method of urban night lighting The urban night outdoor light environment achieves its design effect through colorful lights. Urban night lighting can generally be divided into two types: general lighting and partial accent lighting. Ordinary lighting is set to meet the needs of pedestrian walking at night, and the lighting fixtures are evenly distributed over the urban roads and plazas, and the requirements for the luminaires are not high. In addition to meeting general requirements, local key lighting in the city is still artistic and ornamental. Such as the famous Shanghai Bund and Nanjing Road, the radiant neon lights have become the symbol of Shanghai Everbright City, and it is the place for Shanghai people and tourists to shop leisurely at night. The key lighting design areas usually include urban centers, important urban squares, important urban streets, and important urban buildings.

To increase the luminous efficiency of incandescent lamps, halogen lamps are used to form tungsten halogen lamps. Another type of luminaire is made using the principle of gas discharge luminescence. Such as fluorescent lamps, fluorescent high pressure sodium lamps, and the like. Among them, high-pressure sodium lamps and low-pressure sodium lamps are suitable for street lighting, and xenon lamps are suitable for large-area lighting such as squares.
