What does engineering lighting mean?

The construction of urban lighting project is a systematic project, which should be planned in a unified way according to the design principles, so that the landscape lighting of buildings can be organically combined.

1. Environmental protection principles. There are various forms of lamps in urban lighting projects, and the selection of light sources and lamps should be consistent with the environmental style around the site, so that lamps can have the functions of lighting at night and decorating the environment.

Second, the principle of safety. There are many safety accidents caused by night lighting in cities all over the country. Therefore, the design of urban lighting engineering should be equipped with grounding system and leakage protection to ensure the safety of electrical construction. Then there is the principle of rationality. The design of urban lighting engineering should conform to the characteristics of the surrounding environment, and the lighting brightness at night should be moderate to avoid blind spots and light pollution.

Iii. Lighting design of urban roads: High-pressure sodium lamps or high-pressure mercury lamps are used for road lighting in major cities in China. The former has the characteristics of long life, high light efficiency and energy saving. High-pressure sodium lamps should be the first choice for future and future road lighting projects, so as to improve the lighting level of main roads and strengthen the management and control of urban lighting projects.

Fourth, the urban business district is the focus of the urban landscape. The design of commercial lighting should consider the combination of accent lighting and ordinary lighting, realize the diversification of lighting forms, highlight and render the characteristics of urban commercial buildings, and realize energy-saving lighting. Secondly, the facade lighting design of street view landscape should be strictly regulated in the design of lighting engineering to reduce light pollution. Designers should choose suitable lamps and light sources according to the surrounding environment, outline, surface materials and owner's vision of the building, so as to show the three-dimensional sense and modeling of the building while giving people a good feeling and reducing the negative effects of urban lighting engineering.
