Speeding up the implementation of LED for the implementation of the bidding subsidy -- the seminar on LED lighting product reliability test method was held in Beijing

May 30, 2012, State Key Laboratory of semiconductor lighting joint innovation (chips) (hereinafter referred to as Key Laboratory) one of the key projects of the "LED lighting product reliability test method" seminar held in Beijing, the representative business conference invited domestic with the basis of many years of research in electronic product testing institutions and LED lighting field, the main discussion on testing method for accelerated life and reliability of semiconductor lighting products.

Impact on the global economic recovery still many uncertain factors, the steady growth of economic development in 2012 to become the China tone and goal, to expand domestic demand and further develop the market has become an important driving force to maintain economic growth. Semiconductor lighting industry as a strategic emerging industries, energy saving and environmental protection, and has a strong economic driving effect, has been strongly supported by national policy level. Bidding projects, subsidies continue to spread the news. But the government subsidies to start the project truly stable and reliable, highlighting the advantages of new LED light source products, so many enterprises through testing agency threshold, lined up waiting for the results of the product certification.

"At present, there is still no set of methods for testing the reliability of LED products, including indoor and outdoor lighting. U.S. Energy Star 6000 hours of testing time is too long, can not meet the needs of government tenders. Delegates said. "The integration of various resources from the national perspective, in order to expand domestic demand and develop the market, especially the subsidy tender escort, took out the most effective, the most scientific, most easy to operate products to accelerate the detection task imminent. "Key Laboratory, said Wu Ling, chairman. "LED lighting products accelerated reliability test method and technical specification of LED lighting products is to shorten the assessment cycle, rapid and accurate prediction of the service life of SSL lighting products, the rapid evaluation of products, meet the industry and government bidding requirements. Delegates said.

Belongs to the electronic products LED lighting products in essence, so it can be combined with the accelerated testing method of traditional electronic equipment, combined with the characteristics of LED products, the acceleration detection method to quickly determine the quality of the product reliability. First of all, through the analysis of the stress failure of the product to determine its stress sensitivity factors, the specific ideas can be found through the product is not reliable, to find the most important factors. Through the accelerated test of stress sensitivity, the reliability of the product is derived from the short time stress endurance. Studies have shown that 6000 hours of test time can be reduced to an accelerated test of 1000 hours can be achieved. Delegates said in the discussion. "Temperature, humidity and voltage have a great impact on the quality and reliability of LED lighting products, so we need to consider the core factors to find a method which can realize the short time detection and the credibility of the results. Delegates to discuss.

By the parties of intense discussion and thought about the collision, reached some important consensus to determine the reliability accelerated testing method of LED lighting products, as an important basic work in consultation with the parties, the project unit is responsible for the arrangements for the next phase of work. Believe that under the joint efforts of the industry, the reliability of LED lighting products accelerated test method will be decided as soon as possible for the government to further implement the subsidy policy and continue to lay the foundation, but also help LED lighting products are fast and standardized market.
