The point of profit growth market for the next COB

LED packaging industry in the present stage, some enterprises to carry out large-scale transformation, develop the pan lighting market, seek diversified development, obtain new high gross profit growth point; there are also some enterprises focus on the field of LED packaging products upgrade, through the optimization of product performance and quality, out of the red sea. The flip chip COB (flip chip CSP, COB) model is a higher gross margin to become the enterprise development focus. Flip COB launch at the beginning has been questioned, it still refers to the packaging production efficiency is low, the popularity of blocked. The flip chip COB products Foshan Zhonghao Photoelectric Technology Co. Ltd. from the beginning of last year has been put into trial production and mass production, mainly used in large power and high power density integrated outdoor application. Reporter Aladdin news recently interviewed Zhonghao photoelectric general manager Wang Mengyuan, a star into the package outstanding performance in the field of COB. The low efficiency of COB crystal producing cover not popular? Wang Mengyuan analysis, limited production efficiency of flip chip COB in high precision automation equipment, materials and flip chip packaging process development, the existing printing empty bad, low production efficiency, low cost, light efficiency, better suits and other issues, a comprehensive price is not high, especially in indoor lighting, so many manufacturers have package wait-and-see attitude. "The market of any new technology and new products will need a process." Flip chip COB is a high power density, high reliability and other advantages, although the same power package under the light effect and the price is slightly lower than the formal product, but with the development of material technology of flip chip COB automation equipment, high precision, these problems will be smoothly done or easily solved, and quickly into large-scale application. Of course COB dress in some areas still has irreplaceable advantages, such as special color lighting applications. Two kinds of process form each one has its own merits in different application fields, for a long period of time will coexist for a long time." Wang Mengyuan said. On the other hand, the photoelectric engine /ACCOB/COB+ light source module related products also popular in china. In Wang Mengyuan's opinion, whether it is ACCOB or COB+, optical engine, light source module, are from the customer perspective, bring more convenient supporting solutions for customers and develop products, and packaging manufacturers in the light source after a certain stage of development of the direction of research and development. Although these products have not been widely recognized, but the product is uneven, with the improvement in technology, will be large-scale application. How to break the COB high heat flux problem? In recent years, LED packaging manufacturers competition, LED packaging products also emerge in an endless stream, large-scale manufacturers everywhere, for small and medium sized packaging manufacturers, more is to take different routes, but also to the products of high density integrated, modular, intelligent direction of development. The scale and the capital is still the main line, with high technical strength and market segment difference advantage alienation of companies as well as the living space, in addition will be difficult to survive alone. From LED packaging products, will be the coexistence of various forms of SMD, COB, CSP, commercial lighting, outdoor display, automotive, and other applications will play different forms of packaging each one takes what he needs, the advantage of this species will exist for a long time. While Zhonghao photoelectric will focus on COB field, the COB is not limited to commercial lighting, outdoor lighting, such as industrial lighting, special lighting in the field of automotive lamp light sales accounted for more than the commercial lighting field. COB with superior color performance ability won the lighting companies sought after, but the problem of its existence high density radiation is difficult to break, especially in the high power field, people love to hate". Wang Mengyuan admitted that the heat of LED in any kind of package form, as the COB light source, high heat flux problem also inevitably. In addition to the current radiator by selecting matching, optimization of light source itself is also very important, such as the choice of high conductivity substrate, using high thermal conductivity bonding material, and the optimization of COB process, reduce the thermal resistance, improve module temperature characteristics, heat dissipation problems can be improved COB light source. Commercial COB market has become the red sea? According to Wang Mengyuan said, compared with the same period of 2015, Hao growth of more than 200%, "this is not because the entire industry boom picked up, more important is Hao to achieve greater growth in markets such as the open blue ocean car lights and light color customized lighting and other fields." The next few years, the industry boom will not change much, only LED lighting still fierce competition, enterprises need to develop new application requirements, the product will also involve more market segments, such as the application of UV ultraviolet and infrared induction applications, intelligent lighting applications, such as relative to the current business applications will be the main market in the Red Sea, the market a profit growth. Wang Mengyuan said, Hao also will increase in these areas COB R & D investment, as the main battlefield for a profit growth. But in fact, Zhonghao photoelectric began actively combining intelligent upgrade products as early as 2013, launched for the intelligent lighting color temperature adjustable light source. "But the smart lighting is not only the source of upgrading, more is needed to drive and intelligent module." Zhonghao joint drive control and chip manufacturers to develop intelligent lighting products, such as in the field of Home Furnishing commercial lighting module by WiFi light color control; in the field of automotive lighting through the light source module and vehicle control combined with the implementation of vehicle headlight intelligent adjustment. Wang Mengyuan also said, "of course in the middle part of the
