LED packaging technology ten trends
Last month, Shenzhen Jingtai Optoelectronics Co., Ltd. "Drive Light" product promotion was successfully held in Guangzhou. At the meeting, Jingtai Optoelectronics fully demonstrated LED lighting , full-color display series and 3C series three major areas of LED package cutting-edge technology and the latest device products, attracting a large number of new and old customers to participate.
Jingtai Optoelectronics was established in 2008 with an investment of 200 million yuan. It is a hi-tech enterprise specialized in developing and manufacturing SMDLED, high-power LED and high-end LED application market. It focuses on LED packaging technology and manufacturing.
As of the end of 2012, Jingtai Optoelectronics production base area reached 12,000 square meters, nearly 800 employees, in 2012 the company's total output value exceeded 300 million yuan. "The company plans to achieve annual output value of 1 billion yuan by 2015." Jing Taiwan Optoelectronics Marketing Director Zhang Yuan said at the promotion.
According to Zhang Yuan introduction, Jingtai Optoelectronics introduced the advanced foreign ASM automatic crystal machine, automatic wire bonders, molding machines, automatic cutting machine, SMDLED automatic beam splitting machine, SMDLED automatic loading machine, environmental testing machine, high-precision optical analysis Systems, computer analysis microscope and other world-class fully automatic production line with more than 600 machines.
"At present, the monthly production capacity has exceeded 1000KK / month. The company has made new breakthroughs in high-efficiency COB-MLCOB, small-size power EMC light source and cost-effective COB light source research and development. The overall production scale is at the forefront of the domestic packaging industry." Zhang Yuan said.
Complete package of products unique design leading peer
In this seminar, Jingtai Optoelectronics demonstrated a full range of COB products represented by the new MLCOB (third generation COB packaging technology), including high power LED, medium power LED and other devices used in lighting products. MLCOB as the third generation of packaging technology, the biggest advantage is that it can effectively improve the light efficiency.
Jingtai Optoelectronics Zhang Lei said that the current production of MLCOB light efficiency is 160lm / w, in the laboratory data is more than 200lm / w. At the same time, MLCOB takes into account other COB advantages. For example, good heat dissipation, MLCOB thermal resistance can reach 5 ℃ / W, easy to install, no thermal damage.
"The difference with the traditional COB is that the MLCOB has a unique reflector design and uses polygonal secondary optics, combining these two technologies with the traditional COB technology to make the light efficiency of MLCOB products more traditional 30% -40%. "Lei said MLCOB flagship high-end market, the main demand for the future of LED lighting applications will focus on high luminous efficiency, high reliability, high cooling.
Jingtao Optoelectronics R & D Director Zhang Mao can be pointed out at the promotion conference, the current impact of LED lighting products into the interior factors include price, reliability, standards and performance.
At the meeting, he also introduced EMCLED (Epoxy MoldingCompoundLED) products, including the 2835, 3014, 3020, 3030 four mainstream market specifications devices.
Among them, the medium power 2835 products with a new package structure, with heat sink design; 0.2w, 0.5w can be achieved in high-power product packaging; high luminous efficiency of high brightness, showing light efficiency up to 120lm / w; Can be more intensive, the application of the light effect is more uniform and so on.
LED packaging technology ten trends
At the promotion conference, Jing Wen, General Manager of Jingtai Optoelectronics, summed up the ten trends and hot spots in the domestic LED packaging technology in the future:
1, the power into the mainstream package. Currently on the market products are mostly high-power LED products or low-power LED products, although they have their own advantages, but there are also insurmountable defects. The combination of the advantages of both the power LED products came into being, the mainstream package.
2, the application of new materials in the package. Materials such as thermosetting materials EMC, thermoplastic PCT, modified PPA, and ceramic-like plastics will be widely used due to higher and better environmental resistance such as high temperature resistance, UV resistance and low water absorption.
3, chip ultra-current density applications. Future chip current density will be developed from 350MA / mm2 700MA / mm2, or even higher. The chip will be lower voltage demand, smoother VI curve (low heat), and both ESD and VF.
4, the popularity of COB applications. With low thermal resistance, light type, welding-free and low cost advantages, COM applications will be widely available in the future.
5, higher light quality needs. Mainly for indoor lighting, crystal photovoltaic Taiwan will be the LED interior lighting products RA to 80 as the standard to RA to 90 as the goal, as far as possible lighting products light color close to Planck curve, so that the light can be uniform, non-glare .
6, international and domestic standards to further improve. I believe that with the continuous improvement of LED packaging technology, domestic and international quality standards for LED products will continue to improve.
7, integrated package light engine into a package of values. Integrated package-type light engine will be the next season R & D focus crystal platform.
8, to the power program (high-pressure LED). Future indoor lighting will be more concerned about the quality, driven by cost factors, power solutions will gradually become an acceptable product, and high-pressure LED fully meet the power to the program, but the need to solve the chip reliability needs to be strengthened.
9, for multi-color LED lighting scene lighting. Scenario lighting will be the core competitiveness of LED lighting, LED lighting and the future take off the second need to rely on scene lighting to achieve.
10, the relative reduction of luminous efficiency, cost-effective package factory magic victory. Future indoor lighting will not be too concerned about the light efficiency, but will pay more attention to the quality of light. With the improvement of packaging technology, the cost of LED lamps has become an alternative to traditional lighting sources. As the lighting system enters the home, the price / performance ratio will be valued more and more by customers.
