Where are the real needs of the middle reaches package to the LED lighting chip?

Upstream LED chips as the source , the entire led street lights wholesale industry chain is the most voice link. Insiders believe that , " the development of upstream power enterprises to grow , allowing the LED industry ' bets are alive ', and even change the pattern of China 's LED industry fundamentally ."Therefore, how to meet the midstream upstream chip packaging product development direction , LED product systems to meet quality requirements and cost targets ? Become a challenge for the entire industry chain and address key structural overcapacity . In this regard, the new century LED Network reporter interviewed industry representative 30 LED packaging companies senior technical staff , from their perspective to explore the LED chip packaging company for the real needs of the situation .Quality and stability is the primary considerationIn the actual use of the stability and consistency is an important indicator of the level of LED technology , the manufacturing process due to interference from a variety of different batches can easily cause inconsistent product quality , while the LED chips inconsistencies will undoubtedly affect the yield and stability of the packaging of the product.In the interview, every one , without exception, said packaging companies , purchasing chips primary consideration is the consistency of product quality and stability.Country star power Foshan Co., Ltd. Dr. Li Cheng , deputy general manager , said select chip performance is certainly a major consideration , including the main optical parameters and reliability, while focusing on the optical parameters of light efficiency , wavelength and brightness of the concentration profiles and so on. Fierce price war and then must maintain good quality, otherwise the company's products would not live long.Guangzhou Hongli Opto-electronic Co., Ltd. engineers sand Lei pointed out that the chip is one of the most important factors affecting the LED stability , quality stability of the middle reaches of the chip package and even downstream applications is essential.In addition, the voltage sub-file will affect LED wide and narrow spectral relatively narrow voltage sub-file is more conducive LED off when the spectral concentration Bin , improve yield.Lunda Electronics Corp. Taiwan side said that the current development of the chip, the application still faces major backlight , so the packages , the chip provides few options , coping with different power packages must choose a different chip, general , the main factors determine the chip market is competitive and cost-effective quality stability both in the same light efficiency . Broadly speaking , the quality of stability is more important than price .Executive Vice President Yi Mei -Light ( Beijing ) Technology Co., Ltd. , Chief Scientist Dr. Liu Guoxu LED to the New Century Network reporter On the Road , in the procurement of LED chips , in order to quality for the first element of stability , the stability of the primary confirmation chip technology and reliability.Cost is still the goal of all manufacturers wrestlingWith LED civilian market gradually opened , all the manufacturers are trying to industrial upgrading between "quantity and quality" look for breaking the road. How to improve performance, reduce costs, has become almost the entire LED industry chain wrestling common goal .Wuhu Rui Rio , general manager of led street lights wholesale to New Century Network reporter mentioned , the key points to consider are cost-effective, such as when the customer reaches the whole lamp 100lm / W, we will think about what kind solutions to our customers the most appropriate , and then on-demand solutions choice has the advantage of chips to the current chip market, high light efficiency, relatively high on the high brightness chip prices, packaging cost, is definitely a pressure to provide appropriate and available brightness to meet customer demand package is our concern.Dr. Ma Wenbo president four Chuanbo lion comes Optoelectronic Technology Co., Industrial Research Institute , currently pay more attention to the first price , due to the cost of the chip in the LED industry chain accounts for a relatively large proportion of the decline in chip prices , can to a large extent reduce the price of LED products . In addition , the current LED market competition, cost-competitive products will be more competitive.Guangzhou Hongli Opto-electronic Co., Ltd. engineers sand Lei also said that light efficiency and price is the primary consideration, the current market trend is to fight lm / yuan , the same price you can buy a higher lumens will be more favored by customers . Select chips will compare existing chips , the same price , choose high lumen ; same lumens , choose low- priced chips , we hope that based on the original , light efficiency and price competitive products .
