A criterion for considering the demeanor of a city and the actual effect of adsorption is the pros and cons of its outdoor city lighting. Lighting manufacturers’ overall considerations for the lighting design of engineering buildings are: Observation orientation: Engineering buildings are likely to be inspected from each different orientation, but generally, before the design plan is gradually developed, everyone will first clarify a special one. Position as the key observation position. Distance: The distance that ordinary people are likely to look at. Too far away will endanger the quality of the viewing image of the opposite appearance of the person, and it will also endanger the decision-making of the level of sunlight exposure.

The basic construction of urban night scene lighting has also caused the government's attention. However, everyone should be sober to see that with the enthusiasm for the infrastructure construction of landscape lighting throughout the country, the infrastructure of landscape lighting in some cities has exceeded the level of local social and economic development trends and the endurance of the financial bureau. It consumes resources, electricity and energy, and even endangers the appearance of the city and the natural environment.

The basic construction of the garden landscape should be based on the local development trend level and the urban functional zoning. It should be based on the time conditions and within the limits. The basic construction of the lighting fixtures to ensure the safety of the city operation, etc., should enhance the landscape lighting design from the root. Plan level, improve quality supervision, prevent extravagance and waste, further strengthen the management method of urban night scene lighting, and improve the level of urban specialization and lean management.

Lighting manufacturers need to constantly refer to the surrounding environment and the situation: the boundary line of light and dark between the surrounding environment and the situation will endanger the requirements of the actors on the light source. If the peripheral light source is dark, there must be sufficient light source to light up the subject, if the peripheral light source is brighter, it must be sufficiently elevated to highlight the subject. In addition to the surrounding environment of the engineering building, the raw materials of the exterior wall of the building are also one of the elements that harm the actual effect of the lighting fixture.

In essence, raw materials with rough surfaces such as concrete, sandstone, ceramic tiles, etc., have good results after direct lighting effects. Raw materials with smooth surfaces such as aluminum profiles, stainless steel plates, and laminated glass will cause total reflection, not only light refraction. The actual effect is not significant, and it will also cause environmental pollution. This situation, especially the laminated glass on the reflective surface, is very serious and cannot be ignored. Shiliyangchang, the nightlife culture of modern people, are all the highlights of the outdoor city lighting, and it is filled with prosperous scenery.
