The appearance of LED has broken the design method and ideas of traditional light sources, and also brought about various doubts and reflections. LED standards and specifications are inevitably facing the same test. Recently, an article about "System Evaluation of Guangdong LED Street Light Product Benchmarking System (2010)" (hereinafter referred to as "Benchmark System") has aroused the attention and discussion of the industry. In this regard, Professor Wang Gang of the School of Physical Science and Engineering Technology of Sun Yat-sen University made an interpretation.
Only open is scientific
For the scientific nature of the benchmark system, Professor Wang Gang said: "At this stage, the development of LED lighting technology is not mature enough and stable. It is still impossible to completely determine the final form of technology development. The LED lighting technology is continuously expanding and upgrading, and people are facing the light. Today, with the ever-changing requirements of lighting, the new light source can not play a role in replacing traditional light sources. What is the new LED light source? We need to constantly explore and take the actual development needs as the guide. It is because this is a For long-term exploratory work, the benchmarking system must be open, and only open is scientific."
Compared with the original version in 2010, the LED street lamp and LED indoor lighting product evaluation benchmark system management specifications have been updated a lot. According to Professor Wang Gang, the benchmarking system itself has the characteristics of exploratory and open. It is based on the latest development trend of the domestic and international technology, the latest standard revision and the latest development of detection technology, and the results of continuous tracking and analysis, according to industrial development and application. The actual needs are proposed by the expert committee, and are updated dynamically after technical argumentation and extensive solicitation. The main contents of the dynamic update include: updating and supplementing the benchmark indicators, adopting the latest test methods, correcting the reference range of indicators, and expanding the selection range of benchmark products.
Taking a single champion as an example
Lighting is a branch with many fields and different areas. Different applications and different environments have different requirements for lamps. As a strategic emerging industry, LED lighting, like other emerging industries, has the characteristics of diverse technical routes and rapid development of technology. In addition to meeting the basic mandatory standards, LED luminaires must ultimately meet the current practical application requirements. For example, students who take the college entrance examination must first pass the exam, and different majors will have a subject in the college entrance examination. Focus on. In other words, the benchmark system is not an all-round champion, but a single champion as an example to guide the industry closer to market demand.
Professor Wang Gang made a precise interpretation of this: “Emerging industries are still in development, what is “excellent� This “excellent†is still a staged “excellent.†The benchmarking system is not a “standard†in the general sense. However, based on the development characteristics of the existing new technologies, the products formed by them are based on the national standards, and the working methods are excellent and medium-quality. It does not have the same standard integrity and is only used in the current industry. Some performance and indicators to guide the industry. This method is basically clear in the direction of development, but the technology is still in the stage of promotion and application of relatively immature and unstable emerging industries, which is very effective."
According to the exploratory and open nature of the benchmark system itself, it can be seen that its outstanding advantages are “dynamic†and “selectionâ€. From this point of view, the technical indicators that are now entangled in a certain version of the benchmark system to debate the right and wrong, and no practical significance, Professor Wang Gang's view on this is: "To analyze the specifics of the benchmark system of the original version in 2010 with the current understanding. The scientific nature of indicators and weighting is as absurd as analyzing whether adults can use baby meals as staple foods."
