LED benchmarking system: the best choice in the dynamic benchmarking

The appearance of LED breaks the traditional design methods and ideas of the light source, but also brings a variety of questions and thinking, LED standards, norms inevitably faced with the same test. Recently, an article on the system evaluation of Guangdong LED street lamp product benchmarking system (2010) (hereinafter referred to as the benchmark system) of the article attracted the attention of all sectors of the industry and discussion. In this regard, we listen to Wang Gang, Professor of physics and engineering, Zhongshan University.

Only open science

The science of the benchmark system, Professor Wang Gang said: "at this stage, the development of LED lighting technology is not mature and stable, still can not completely determine the final form of technology development, LED lighting technology in expanding and upgrading, and people's requirements for light and illumination changing today, the new light source can play the role is not only to replace the traditional light sources. LED new light source go from here? We need to continue to explore, with the actual needs of development as a guide. It is precisely because this is a long-term exploratory work, benchmarking system must be open, only the open is the scientific. "

Compared with the original version in 2010, LED street lamp and LED interior lighting product evaluation benchmarking system has been a lot of synchronization update. According to Professor Wang Gang, the benchmark system itself has the characteristics of exploration and opening, according to the development status of domestic and abroad to keep track of the latest technology trends, the latest revision of standards and the latest detection methods of analysis results, according to the actual needs of industrial development and application, proposed by the Committee of experts, through technical demonstration and solicit the views of dynamic update, dynamic update of the main contents include: update and supplement, benchmarking index using the new test method, the revised index reference interval, expand the benchmark product selection etc..

Take the individual champion as Example

Lighting is a branch of both multi fine areas, different purposes, different requirements of the environment on the lamp is not the same, LED lighting as a strategic emerging industry, and other emerging industries, with technical route diversity, characteristics of the rapid development of technology, LED lamps in addition to comply with the basic standards of compulsory outside the final also need to meet the current actual application requirements, like the students to participate in college entrance examination, you must first through the examination, and different professional a subject for the college entrance examination will be focused on. In other words, the benchmark system is not the choice of Almighty champion, but a single champion as an example to guide the industry close to the market demand. Professor Wang Gang made a precise interpretation of this: "emerging industries are still in development, what is" excellent "? This "excellent" is still the stage of "excellent"". The benchmark system is not a general sense of "standard", but according to the characteristics of the existing development of new technology, the formation of the products meet the national standard on the basis of the above work, an optimization method of the selection, the integrity of it does not have the same standard, only applied to some performance indexes of industry of current concern. In order to guide industrial. This method is basically clear for the direction of development, but the technology is still in the relatively immature and unstable emerging industries in the stage of the promotion and application, very effective. "

According to the characteristics of the system itself, such as exploratory and open, it can be seen that the prominent advantages are "dynamic" and "optimal"". From this perspective, technical indicators are now wrestling with a version of the benchmark system to non debate, and there is no practical significance, Professor Wang Gang this view is: "the science of the concrete index and weighted by now to realize on the initial version of the 2010 benchmark system, with the analysis of adults can use baby food as a staple food as absurd.
