An analysis of a profit growth point in the COB Market

In the current stage of LED packaging industry, some enterprises carry out large-scale transformation, open up the field of universal lighting market, seek diversified development, obtain new high Maori growth points, and some enterprises focus on the product upgrading in the field of LED packaging, by optimizing the performance and quality of the products, to kill the Red Sea. In addition, the new type of chip, such as overlying COB (COB) and CSP, has become a hot topic in the development of enterprises. Overburden COB has been questioned at the beginning of its introduction, and it is still pointed out that the efficiency of the packaging production is low and the popularization is blocked. And the overburden COB product of Foshan Zhong Hao Optoelectronic Technology Co., Ltd. has been put into production from last year and realized mass production. It is mainly used in the application of ultra high power integrated outdoor and high power density vehicle lamp. Aladdin News Center reporter recently interviewed Wang Mengyuan, general manager of Zhong ho optoelectronics, and entered the package new star in the COB field. Is it difficult to popularize the low production efficiency of overlying COB? According to Wang Mengyuan, the production efficiency of overlying COB is limited to the development of high-precision automation equipment, materials and reverse packaging technology. At present, there are problems in solder paste printing holes, low production efficiency, low light efficiency, lower cost, and low cost performance, especially in indoor lighting. Many packaging manufacturers hold a wait-and-see attitude. "The marketization of any new technology and new products requires a process." The overburden COB is a high power density integration with high reliability and so on. Although the optical efficiency and the cost performance of the same power package are still slightly lower than the positive products at present, with the development of the high precision equipment and material technology of the overlying COB, these problems will be solved and quickly entered into large-scale applications. "Of course, the formal COB still has an irreplaceable advantage in some fields, such as the application of special light color lighting. The two process forms have a long time in different fields of application, and a long period of time will coexist. " As Wang Mengyuan said. On the other hand, the light source related products of the /ACCOB/COB+ module of the photoelectric engine are also being sought after in China. In Wang Mengyuan's view, whether it is the photoelectric engine, ACCOB, or the COB+ module light source, it is the product developed from the customer's point of view, which brings more convenient solutions to the customers. It is also the direction for the packaging manufacturer to develop the light source after the development of the light source. Although these products are not widely recognized at present, the products are also uneven, but with the improvement of technology, it will be used in large scale. COB high heat flow density heat problem how to break? In recent years, LED packaging manufacturers have been competing fiercely, and LED packaging products are emerging in an endless stream. For small and medium-sized packaging manufacturers, more is the route of differentiation, and the products are also developed in the direction of high density integration, modularization and intelligence. Scale and capitalization are still the main lines. Enterprises with high technical strength and subdivision of differential market also have space for survival. In addition, it will be difficult to survive alone. From the LED packaging products, it will be SMD, COB, CSP and other forms of coexistence, business photos, outdoor, automobile, display and other applications will be required, each play the advantages of different packaging forms, these forms will exist for a long time. And Zhong Hao optoelectronic is focused on the development of the COB field. At present, its COB is not limited to business illumination, such as outdoor / industrial lighting, automobile lighting, and special lighting and lighting. COB is highly sought after with superior light and color performance, but the heat dissipation of high heat flux is difficult to break through, especially in the field of high power, which makes people "love and hate". Wang Mengyuan confessed that the heat dissipation problem of LED exists in any kind of packaging form. As a COB source, the heat dissipation of high heat flux is also unavoidable. At present, the optimization of the light source itself is also very important in addition to the selection of the matched radiator, such as the selection of high heat conduction substrate, the use of high thermal conductivity bonding material, the optimization of the process process of COB, the reduction of the overall thermal resistance and the improvement of the temperature resistance of the module, so that the heat dissipation of the COB light source can be improved. Commercial COB market has become the red sea? According to Wang Mengyuan, compared with the same period in 2015, the performance of Zhong Hao has increased by more than 200%. "This is not due to the recovery of the industry 's prosperity, but more mainly by the greater growth of Zhong Hao in opening the blue sea market such as car lights and light color custom lighting." The industry prosperity in the next few years will not change too much, lighting still is still fierce, LED enterprises need to open up new application needs, and the products will also involve more market segments, such as UV UV application, infrared sensing application, intelligent lighting application and so on. The main market for profit growth. Wang Mengyuan said that Zhong Hao will also increase its COB R & D investment in these areas as the main battleground of the next profit growth. In fact, in 2013, Zhong Hao began to actively combine intelligent product upgrade with intelligent lighting, and introduced a adjustable temperature light source for intelligent lighting. "But intelligent lighting is not only the upgrading of the light source, but also the need to drive and cooperate with the intelligent module." Joint drive control and chip manufacturers to develop intelligent lighting products, such as control light color through WiFi module in the field of home business illumination, and realize intelligent adjustment of light and near light of automobile headlights through combination of light source module and vehicle control in the field of automobile lighting. Wang Mengyuan also confessed, "of course, the middle reaches of the link are all" small intelligence ", and the real" big intelligence "also needs to be excavated and driven from the application terminal.
