Dr. Li Nong, Director of the Institute of Urban Lighting Planning and Design, Beijing University of Technology
Qianjia.com: How do you view the current status of Chinese lighting from an expert perspective? There are development trends in the lighting industry, please talk about it.
Dr. Li Nong: Compared with the past, the lighting industry is developing rapidly. The important reason is that market demand is growing. The increase in market demand is mainly due to the introduction of national energy-saving standards, resulting in the replacement of light sources. On the other hand, the rapid development of landscape lighting has also opened up the rapid development of the lighting industry in the lighting industry and its indirect reasons, that is, the economic development, people's demand for lighting is also growing. The lighting industry has been developing for more than a decade, but it is still an emerging industry compared to other industries. From the perspective of the development trend of the lighting industry, it should be the standardization and scientificization of the industry. The so-called standardization refers to the standardization of all aspects, including: pre-lighting design, medium-term product supply, and post-construction. In terms of lighting design, the country has begun to implement lighting designer qualifications, standardizing lighting design, and standards for indoor and outdoor lighting are being revised. The so-called scientificization has two meanings. On the one hand, the meaning is energy saving of lighting. This is also the eternal theme. On the other hand, it means the scientificization of all aspects of the construction process. From the perspective of lighting design, the continuous improvement of the level of employees and the continuous improvement of the lighting design system will become the future development trend. In addition, major events such as the 2008 Olympic Games and the 2010 World Expo will also promote the development of the lighting industry.
Qianjia.com: What do you think is the most important thing in lighting design? Which of your designs has impressed you the most?
Dr. Li Nong: The design requirements for lighting are aesthetically pleasing from the perspective of the landscape, and they can stand up to the design. In terms of landscape, lighting design will vary according to the designer's design literacy. In terms of design technology, designers should consider issues such as energy saving, safety, and longevity. The lighting designer's qualification assessment will also make the lighting design more standardized and reasonable. I think the lighting planning and design of the Phoenix Building in Sichuan is a relatively guiding design. Its design is based on the lighting design of the "Light Culture" design concept. The essence of the design concept of "light culture" refers to the communication of culture through light.
Qianjia.com: Nowadays, lighting energy saving has become a hot spot in the industry. How do you think that the lighting energy saving concept can be better integrated into lighting design?
Dr. Li Nong: Any industry should establish the concept of energy saving. From the perspective of lighting design, the concept of energy saving should be implemented in all aspects of lighting design, including the determination of lighting design, lighting equipment selection and lighting control. Appropriate reduction of the use of the appliance on the basis of ensuring illumination is a consideration in the lighting scheme, and the selection of an efficient lighting fixture can also achieve a good energy saving effect. The lighting control time is used to control the lighting time. In addition, selecting an efficient lighting control device will also have a better effect. This requires designers to understand the energy savings of various lighting control devices. In the process of construction, energy conservation will also be involved. Therefore, designers should consider the issue of energy conservation from all aspects of design and select the corresponding lighting products to achieve energy-saving effects. Some people think that energy saving is the choice of light source, which is also a misunderstanding. On the basis of ensuring the effect of landscape lighting, energy reduction can be achieved by reducing the number of light sources used. By controlling the way of controlling lighting, energy saving can also be achieved. Light source is only one of the ways to save energy.
Qianjia.com: Nowadays, urban landscape lighting is being built everywhere. How do you think about the effect of urban landscape lighting and lighting energy saving in lighting design?
Dr. Li Nong: Many areas are now building landscape lighting for the city. The objective reason is the need for economic development in various places. This also requires that from the level of urban planning, we must put a good energy-saving, and do a good job in overall planning and planning. Planning from a large level and designing from a detailed level is the system's energy-saving method.
Qianjia.com: Please talk about the future trend of urban landscape lighting design.
Dr. Li Nong: The future trend of urban landscape lighting design is that the scale of landscape lighting will also expand. From the city's investment attraction, commercial sales at night can have a very good effect. Through the construction of urban landscape lighting, the urban environment will be improved, and the city will be more convenient for people to travel. Therefore, the urban landscape lighting will be further expanded in terms of scale. Standardization and scientificization will also make landscape lighting more scientific, more orderly and healthier.
Qianjia.com: Now more and more manufacturers are putting forward the slogan of “light healthâ€. You are an expert specializing in light environment research. What do you think about this slogan?
Dr. Li Nong: “Light health†is a basic requirement in the use of light. It was not proposed, but it is now raised. This is related to people’s understanding and economy. Originally, the demand for lighting products was only simple lighting. There were no excessive requirements, and lighting manufacturers had no relevant design. However, with the development of the economy, people gradually had health requirements and began to notice safety including electromagnetic radiation. The problem. It is now the slogan of "light health", which is also the inevitable development history of the lighting industry. Try to reduce as much as possible the negative effects of light on human beings. Similarly, try to dig out the light that is good for human health. This also requires that all parts of the industrial chain, including manufacturing, design, etc., must consider health issues in order to make the lighting develop in a healthier direction.
