In the lighting industry, from time to time will hear the "professional" voice of some professional outsiders. Most of them are evaluations of lighting quality, such as light pollution, glare and other terms are more catchy, but really have to ask the bottom, many people do not have an accurate definition of these professional terms, but personally feel:
Really shaking, light pollution!
Colorful, light pollution!
Too bright, light pollution
If you don't do anything, you will get some colorful light pollution!
If you only rely on personal senses to judge things that you are not familiar with, you will be biased. In fact, there are standard differences in light pollution in the world. Generally, light pollution is generally divided into three categories, namely, white light pollution, artificial daylight and color light pollution. Each category has a subdivision standard identification standard. In view of the limited space, it will not be introduced one by one.
And those light pollution often use media architecture as a carrier. In this issue, Mr. Chang Zhigang will give us a deep analysis of the concept of media architecture and light pollution.
1. Night light environment and media building
The evaluation of media architecture is very different, and the evaluation angle should be comprehensive.
It is a real phenomenon that media organizations are mixed. But this may be more in the field of designers, especially in China, and more is that the lighting industry is paying attention to this matter, so it cannot be said in general terms. Last year's 11th G20 summit in Hangzhou, it may be mixed in the design circle, but the local people and the government like it very much, so in his view, the general approach is not rigorous.

Media architecture, which originated from a form of public art, a work or a creative approach, was later evolved in architecture. In China, more and more lighting designers are involved in it, and it is used as a design method for building facade lighting, which is a staggered and unclear relationship. The different evolution of these two ideas has produced differences in understanding of media architecture.
The evaluation of media architecture should first look back to its origin, public art. Does it play a role in shaping the space and promoting public behavior in public space? From the perspective of lighting design, to judge a series of problems such as light pollution, energy consumption, etc., we need to integrate as much as possible from the aspects of architectural space, public art, architectural performance, lighting design, night vision environment and so on. To evaluate, we will get more objective conclusions.
Similarly, from the perspective of lighting design, there are different judgments on the evaluation of its quality. For example, the traditional lighting method on the performance of the building, the emphasis on the structure and volume relationship of the building, such a relationship has changed in the moment, the lighting of the building is no longer just reflecting light, sometimes the building has become light origin of. Some buildings are autonomously illuminated, and naturally, the evaluation criteria should be different.

For the aesthetic value, this is not an objective evaluation, but these are from the ordinary people or outside the industry evaluation, they are not professional, but it is the most intuitive judgment of the public, it can be used as a basis for evaluation. Correspondingly, the judgment in the profession needs to be cautious and not too rashly negated.
In the face of negative impacts, we should think about solutions. We should not be ruined. The evaluation of the impact on media buildings should see his two sides. We need to establish an attitude, even if it is mixed, even if the disadvantage is greater than the benefits, but if it It is the future direction of development. What we should do is to go to its dross and take the essence, instead of the disadvantages outweighing the advantages, we will abolish the whole idea, so we cannot simply blindly evaluate the public opinion in a single direction.
