Urban lighting engineering not only looks good with more lights, but also represents the economic level of a region and can stimulate and drive urban economic development. Currently, governments in various cities also attach great importance to urban lighting work, considering its construction as an important measure to improve and beautify the urban environment, and the government provides fixed funds every year to subsidize lighting costs.However, today's urban lighting projects have evolved from simply pursuing brightness to pursuing artistic and scientific brightness. Although the lighting schemes for these three bridges in Shanghai were customized by the Shanghai Municipal Government, in practice, many lighting projects such as buildings, parks, and squares are designed and constructed by professional advertising companies or lighting engineering companies that undertake lighting projects.

Urban lighting engineering can be divided into several categories, including road landscape lighting, garden and square lighting, architectural landscape lighting, and decorative lighting lighting. The first three are large-scale engineering projects, and there are many factors that need to be considered in design and construction, such as the overall development positioning of the city, the specific functions of roads, the lighting effects presented by buildings and buildings, and overall energy consumption. Decorative lighting mainly serves a decorative purpose, enhancing the atmosphere and achieving interaction.

Lighting engineering is actually a highly technical task, which involves designing a visually appealing effect. It must consider many aspects such as lamp type, power, lamp position, projection direction, and calculation data. So, during the design process, it is necessary to calculate the brightness distribution of the lighting and draw a lighting effect diagram based on the on-site situation and years of experience, so that the effect diagram can be presented close to the real effect.

Nowadays, lighting projects in the suburbs of many big cities and third - and fourth tier cities cannot be so professional, especially when encountering some less professional contracting companies. Many projects involve combining various lights such as simple color digital tubes, projection lights, and cross lights, and using the number of lights to achieve brightness. This leads to many cities having no aesthetic or almost identical lighting, and even causes resource waste. So, when choosing a lighting engineering supplier, it is important to consider their strength and past project operation experience. It is important to check their actual case effects and not just believe in the provided design renderings. As future urban lighting projects shift from requiring "brightness" to requiring "beauty", the layout of urban lighting projects will also become more scientific, and higher requirements will be placed on design and construction parties. Therefore, in order for advertising companies engaged in related businesses to maintain a strong advantage among numerous competitors, in addition to continuously developing lighting solutions, they also need to master more relevant technical knowledge and provide suitable and scientific lighting solutions after considering various situations comprehensively.
