Interview with He Bingyun: Talking about Urban Landscape Lighting (Photos)
Landscape lighting is an important part of engineering lighting and one of the most concerned hot spots in the lighting industry. For landscape lighting projects, both the functionality and the ornamental nature should be considered. Aladdin reporters should make an exclusive interview with senior engineers He Bingyun, executive director and secretary general of Tianjin Lighting Society, who has been paying attention to the landscape lighting project for the specific points of attention of landscape lighting projects.

Reporter: How to assess the pros and cons of a landscape lighting project? What are the specific criteria?
He Bingyun High-tech (hereinafter referred to as He Gong): Last year, several experts from the Tianjin Lighting Society and the Municipal Committee of the City, including me, wrote a “Tianjin Urban Landscape Lighting Project Acceptance Specificationâ€, which was made for the acceptance of urban landscape lighting projects. Some aspects of the regulations are now being tested. I think that for urban landscape lighting, there should be two attributes: one is functional and the other is ornamental. For ornamentals, it is a distinctive feature of urban landscape lighting that distinguishes it from other lighting.
In the country's total multi-assessment norms and acceptance specifications, it emphasizes the aspect of engineering "electrical engineering construction quality". As the acceptance standard for landscape lighting projects, on the basis of meeting the "electricity" standard, the acceptance of the landscape effect of the project should be added, that is, the evaluation criteria for ornamental and artistic aspects should be increased. Specifically, it includes the safety of the project, the beautification function, the function of use, the health of the human body, energy conservation and environmental protection, environmental benefits, and public interest. It is necessary to evaluate the quality of electrical engineering construction, evaluate the artistic effects and visual effects of landscape lighting, evaluate lighting energy-saving indicators, and evaluate light pollution control.
Light pollution problem has a generation of strengthening constraints

Reporter: Since light pollution is one of the standards for engineering assessment, is the light pollution in China's big cities serious? What are the reasons for the light pollution in China?
He Gong: Light pollution is the phenomenon of interference or negative impact on people, things and the environment caused by spilled light, reflected light and glare generated by urban outdoor lighting at night. From the aerial image analysis, there are obvious bright and dark areas. Generally, the areas with more developed economy are brighter, and the situation of light pollution is relatively serious. The southeast coast of China is also relatively bright. In recent years, with the rapid development of urban night lighting, especially the high-power high-intensity discharge lamps widely used in architectural night lighting and road lighting, light pollution has become more and more serious. In addition, the neon lights, light box advertisements and light signs on the commercial street are increasing and larger. There are two main reasons: First, the use of the unit's thinking, think that the brighter the better, the building you build is brighter, I want to be brighter than yours; the second is to design the construction unit's economic interests, thus accelerating the development of light pollution .
In addition, due to the unscientific installation technology, the problem of glare caused by indoor space and road drivers is also a problem worthy of attention.
Reporter: Is there a corresponding regulation that restricts light pollution?
He Gong: For light pollution, the country does not yet have a specific regulatory constraint. However, due to the seriousness of the light pollution problem, the relevant state departments and industry insiders attach great importance to this issue, and now the agenda has been mentioned. Internationally, some countries also have restrictions on the light pollution index. We can refer to the implementation, but it is only a control indicator and should be regulated as a regulation. The Ministry of Construction recently issued documents, such as pointing out that it is not a landmark building, it is absolutely not allowed to use lasers, and it is not allowed to use large wattage lights.
