Liang Bingwen: learn from the United States solid state lighting program to promote the development of China's LED lighting industry

Solid state lighting America (SSL-solidstatELighting) program is a comprehensive, including the field of plan, which includes basic research, application of the key technology research and development, product development and marketing of several parts, each part is relatively independent and interrelated.

In the United States, the core technology research and development work is usually undertaken by the Institute, university or national laboratory. Through the core technology research and development, in solving some of the basic and common technical problems, the enterprise can according to their own market positioning to develop the corresponding products. Of course, the strength of large enterprises can also engage in a number of core technology research and development work, but this is a minority.

Research of the core technology of the general setting is the first solicit society, industry and academic institutions, which please put forward the core technology of the problem, several times to discuss the organization arrangement, and by Technology Committee of experts based on the core technical problems to sort out the corresponding research, for project application to the society. After receiving the report, the U.S. Department of energy, the organization of expert review, through the respondent and on-site investigation and other forms to determine the success of the unit. Project funding is usually in the hundreds of thousands of dollars to millions of dollars, funding period of 2 to 3 years. The U.S. Department of energy will also fund some product development projects.

Rapid introduction of testing and standards are worth learning

At present, the United States solid state lighting project to promote the bright spot, I think it is CALiPER (CommerciallyavailableLEDproductevaluation andreporting) test project operation and the rapid introduction of new standards. CALiPER test results show that the average efficiency of LED lamps with the times, the maximum luminous efficiency of more than 70 lumens per watt.

Like China, the U.S. market has a variety of LED lighting products, but also marked by the technical performance indicators are diverse, there is an obvious phenomenon of exaggeration. In order to regulate the market, the U.S. Department of energy in 2006 organized a project called CALiPER. The operation of this project is a regular or irregular sampling of solid state lighting products from the market, and compared with its logo, the results made public. Up to now CALiPER has conducted 7 rounds of testing. The first sampling results are surprising, the manufacturers of the nominal index and sampling test results vary greatly, most of the products identified by the optical efficiency index is much larger than the data obtained from the test. After the test data published in the industry caused a great response, manufacturers have begun to realize that exaggerated practice is not desirable.

Of particular note is that the core technology research and development, product development and marketing of these three parts of the research unit and the company formed a strong strategic partnership. We teamed up to promote rapid and healthy solid-state lighting products to enter the market and application, product development and marketing is to establish standards based and implementation, no timely introduction of standards and strict quality supervision, the new products are difficult to health to explore the market, because in this period is often unscrupulous manufacturers to counterfeit the means of producing a large number of inferior goods, and with low quality products will be out of the market, the result is of poor quality new product market reputation ruined and finally the whole industry. In the past few years, the United States has introduced four standards for LED lighting.

The market does not regulate the development of the industry to bring hidden dangers

In recent years, China in the promotion of semiconductor lighting technology to do a lot of work and made great achievements, especially in the industry alliance, industry exchange performance significantly, and has caused the national levels of government attaches great importance to the LED lighting. But in the market promotion and market norms do not get too much, grasp the real, making poor products flooded the market, for the healthy development of the LED lighting market has brought a lot of hidden dangers. In terms of market regulation, the U.S. Department of energy CALiPER approach can be used for reference.

In addition, LED belongs to the energy-saving products, but because the standard has not issued, the national energy-saving lighting products in the market to give support in place, greatly affected the promotion and application of LED lighting products. These issues require the relevant departments of the government and relevant industry associations, as well as the alliance to solve. Only with a relatively standardized market and timely introduction of relevant standards, the semiconductor lighting industry will be healthy and orderly development.
