Li Tienan: Five expectations for lighting design (Figure)

Need to improve lighting design level
The lighting design industry has experienced a long process from scratch, from passive needs to active design. Nowadays, people are paying more and more attention to the lighting environment, and lighting designers are playing an increasingly important role in the built environment. In different architectural environments, lighting designers should design lighting according to the functions of commercial buildings, office buildings, home buildings and other buildings, the use of the elderly, adults, children, and other special needs.
As far as the overall development status is concerned, China's lighting design has developed rapidly, but there are still some gaps between the design level and the lighting design level in developed countries. There are many reasons.
First of all, due to the low entry barriers for lighting professionals and the number of people entering the threshold, the overall form of domestic lighting design is relatively rich, and there are many practitioners, but there are not many people who do well; secondly, China's lighting design industry Compared with developed countries, the lighting design industry in China has grown by leaps and bounds in recent years. This has enabled more and more people to join the industry to cut the market cake. There are often jagged situations; in addition, the profit point of the lighting design industry is also one of the reasons. These profit points have attracted more interior designers, electrical designers and architects to join the lighting design industry. . In general, although there are many lighting designers engaged in lighting design, there are very few people trained in professional lighting design. Many lighting designers are architects, interior designers and electrical engineers, so lighting design is improved. The professionalism level of the division is very necessary. However, the current low level of the domestic lighting design industry is also a necessary stage for the development of the industry. I believe that in the next few years, the lighting design industry will begin to mature.
Need to improve the implementation of standard specifications
At present, in terms of lighting, the state has successively formulated or is in the process of formulating many relevant standards, norms and local standards, such as the "Technical Specifications for Night Lighting" and some safety regulations, energy-saving regulations, and regulations for preventing light pollution. Norms and standards have played a role in management, regulation, restriction and promotion of the sound development of lighting design applications. Therefore, they are very particular about normative and rigorous. The implementation of national and local regulatory standards requires the cooperation of various departments. Standards and norms can only be implemented if they can be implemented. After the specification is issued, the implementation is mainly solved by the management department. If the plan is supervised by the municipal department, the building is approved by the construction department or the city management department. Although the implementation of various standard specifications in the lighting industry has yet to be improved, the results received are obvious to all. As long as the correct standard specifications guide, the lighting design industry will certainly get better and better.
However, in China's lighting design, there are still some problems to be solved in the actual implementation of the standard specifications. For example, some professional vocabulary understanding is not thorough, such as energy-saving lamps. In terms of specific meaning, the English name of the energy-saving lamp is CompactFluorescentLamp, which is interpreted as a compact fluorescent lamp. Therefore, the energy-saving lamp does not include the fluorescent tube that we commonly use. However, many architects, interior designers and even lighting designers often attribute fluorescent tubes to energy-saving lamps. Strengthening the communication and connection between the standard norms and the designers, so that the standard specifications are correctly explained in the designer needs to be improved.
