Urban night lighting has received more and more attention from all walks of life and plays a very important role in daily life. Led city lighting project lighting enriches and beautifies the city's nighttime landscape, reflecting the comprehensive level of urban economic and cultural development, which stimulated consumption to a certain extent and stimulated economic demand.

Outdoor lighting fixtures should have reasonable planning. Its planning and design should be clear and orderly, and it can reflect the lighting order of the whole city on a macroscopic level. Led city lighting engineering lighting organically combines various lighting elements such as buildings, commercial streets, parks and plazas to make our urban night landscape a beautiful picture.

Led city lighting engineering lighting energy-saving, ecological, sustainable development has been more and more people's attention. Saving energy, improving lighting quality, reducing glare and light pollution, and protecting the environment are all important aspects of urban lighting development and construction in the future.

The bridge is an important and convenient traffic artery in the city. The LED landscape lighting project is designed to illuminate the lamps through different lightings, showing the majestic appearance of the bridge and decorating the night sky of the city.

Outdoor lighting manufacturers, first of all to determine the location of the lighting, lighting the spacing and height of the lighting settings, directly affect the actual effect of the lighting of the bridge and the difficulty of maintenance management. If the luminaires on both sides of the bridge are too high, the radiation radiation and reflection effect are not obvious. At the same time, if the position of the illuminating luminaire is too high, the luminaire is easy to receive external damage, and the safety hazard and operation and maintenance costs are increased. The led landscape lighting project is mainly to highlight the shape of the bridge and achieve the purpose of beautifying the city at night.

The original intention of nighttime outdoor lighting fixtures is to continue the prosperous landscape of the city during the night, and to use the reasonable configuration of neon light to show the bustling scene at night. The building during the day is illuminated by a full range of continuous solar spectrum light to form a first contour. In the evening, the artificial lighting mix, mostly from the bottom up, is constructed as the second contour of the architectural landscape, creating a landscape that is different from the daytime landscape.

Therefore, we must first form a continuous lighting landscape, the lighting through planning and control, reflecting the street's own characteristics, street lights, advertising light boxes, light bridges arranged neatly, along the street building lighting continuous and climax, and in a series of continuous The changes have caused the entire street to rise to a large scale of circular art works, which gives viewers a strong sense of beauty.

The general lighting design of the street should start from the following aspects:

(1) Determine the key areas of the light and form multiple lighting orgasms in the longitudinal direction;

(2) Multi-layer light distribution of the constituent elements, forming a omnidirectional, horizontally up-and-down lighting effect in the lateral direction;

(3) The lighting configuration adopts dynamic and static combination;

(4) Pay attention to the embodiment of urban characteristics.
