Exclusive packaging domain

If 2013, the patch is the mainstream; That 2014, COB packaging is gradually changed to the protagonist, the total production increased by 20% to 30%. Among them, COB-packaged bulb lamps even account for 40%-50% of the market.

COB package is Chip On Board, that is, the bare chip is attached to the interconnect substrate with conductive or non-conductive adhesive, and then the lead bonding is carried out to achieve electrode connection. Because it is easier to achieve dimming color, anti-glare, high brightness and other characteristics, it can solve the problems of color difference and heat dissipation, and has been widely used in commercial lighting and other fields.

According to relevant data, the overall share of COB packaged products in China has exceeded 7%, and it is widely used in high-power leds for street lights, direct-down backlights, spotlights and other high-brightness application equipment, and its demand will increase from 18.5 billion in 2014 to 27 billion in 2017, with a compound annual growth rate of 13%. Some international packaging manufacturers predict that by 2017, the power, COB, and high power will be divided into three parts in terms of output value.

COB dominates the competition between domestic and foreign enterprises

At this stage, the domestic COB packaging market is still dominated by foreign enterprises such as Citadel, Sharp and Cree, because it has the advantage of technology pioneer and brand awareness in COB light source. However, with the gradual maturity of COB technology, forced by the fierce market, some domestic manufacturers COB packaging devices have been comparable to foreign companies in performance.

This year, international giants and domestic LED companies have expanded their COB product lines, improved performance, and made innovations. At the Light Asia exhibition, Samsung Electronics exhibited a series of high-performance COB LEDS, Lumileds, and Purui Optoelectronics exhibited a series of high-performance COB leds. As the most important strategic partner of Purui Optoelectronics in mainland China, Liyang Optoelectronics mainly promoted the COB products with 120lm/w high power, high light efficiency, Ra>90 high display and high reliability. With the use of lighting solutions and calculus optical lenses provided by Liyang Optoelectronics, the research and development cycle can be shortened, the cost can be reduced, and the product can be quickly introduced into the market.

Three product lines lead the technology frontier

In the LED industry, reducing costs and improving performance is an eternal trend. Better products with lower prices, this seemingly paradoxical phenomenon, hidden is the strict control of Liyang Optoelectronics for the cost. Light source, lens and other components of Liyang Photoelectric are their own production and development, reducing the procurement of lamp beads, lenses, radiators, molds and other parts, virtually reducing their own costs.

"In terms of light sources, we are now mainly producing SMD, COB and medium and high-power integrated light sources," said Yang Xiaojun, vice president of manufacturing of Liyang Optoelectronics, "of which COB has 12 fully automated packaging production lines."

The capacity of the newly moved modern production plant has expanded by 3 times, with 10,000 level static dust-free workshop, the current SMD patch production capacity reached 35KK/ month, COB production capacity reached 15KK/ month, production capacity jumped to the forefront of the country, of which the main size and customized products accounted for 50%, according to Yang Xiaojun estimated, In the second half of the year, the existing production capacity of each series of products can be increased by 50%.

Liyang shining future

COB is undoubtedly the current mainstream form of LED packaging, domestic COB as the main product of the enterprise is not a few, and Yang Xiaojun full confidence in their own COB, up to 90~95 color index, 120lm/w above the light efficiency, higher than the industry 20% level, COB full series through the LM-80 certification, Our products cover many market areas such as indoor lighting and commercial lighting.

It is understood that in the industrial chain, Liyang Optoelectronics has also formed a close strategic partnership with the top enterprises in the industry, and has now become the world's largest chip crocodile - the United States Pruezhong high-power chip product line in China's largest customer, often conduct business and technology exchanges.

In order to meet the market demand, Liyang Optoelectronics continues to increase the research and development, experiment and production of COB light source, medium and high power integrated light source. At present, LY-4040 series COB products have the characteristics of high power and high luminous density. Compared with conventional COB, they have full light distribution, comfortable light type effect and better penetration.

At present, COB in different packaging forms on the market has a segmented application trend, and COB light source has many development areas that can be deeply explored, such as medical lighting, agricultural lighting, automotive lighting, fishery lighting, life lighting, etc. "In response to the different needs of the market, enterprises can make products professional in the subdivision field, at the same time, do the corresponding marketing promotion, and then expand the business volume, followed by focus on management, optimize the delivery time, and timely meet customer needs," said Huang Ming, manager of the Marketing Department of Liyang Optoelectronics.

In the end market for the ultimate pursuit of cost-effective, COB localization is accelerating. With the continuous unification of standards, COB market competition will continue to upgrade. In the future, technology upgrading is still a winning weapon to improve COB performance and reduce prices.
