Analysis of a profit growth point in COB Market

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. Among them, the flip chip COB (flip chip COB), CSP and other higher margin has become a new type of chip companies competing to develop hot spots.

Flip chip COB at the beginning of the launch was questioned, is still accused of packaging production efficiency is low, the popularity of blocked. The Foshan City Hao Photoelectric Technology Co., Ltd. COB crystal products from the beginning of last year has been put into trial production and mass production, mainly used in ultra high power integrated outdoor and high power density lamp applications. Aladdin News Center reporter recently interviewed Hao Hao, general manager of optoelectronics, into the field in the field of COB has a good performance in the packaging of the new star in the field of.

The low efficiency of COB production is difficult to popularize

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. Any new technology, new products, the market needs 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 is still an irreplaceable advantage in some areas, such as special lighting applications. Two different forms of technology in different fields of application, for a long time will coexist for a long time. Wang Mengyuan said.

On the other hand, the photoelectric engine /ACCOB/COB+ module light source products are also sought after 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, the product is uneven, but with the upgrading of technology, will be a large-scale application.

COB high heat flux cooling problem how to break?

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. Scale and capitalization is still the main line, with high-tech strength and differentiation of the market advantage of the enterprise there is room for survival, in addition, it 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 to the superior performance of the light color has been sought after by the lamp enterprises, but the existence of high heat flow density heat problem is difficult to break, especially in the field of high-power applications, people love and hate". Wang Mengyuan admitted that LED heat dissipation problem in any form of packaging are present, as a COB light source, high heat flux heat dissipation problem is also inevitable.

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 that China will also increase R & D investment in these areas of COB, as the main battlefield of the next profit growth.

In fact, as early as in 2013, Hao Hao optoelectronic products began to actively cooperate with the upgrade, the introduction of intelligent lighting can be used to adjust the temperature of the light source. But the smart lighting is not only the upgrading of the light source, more is the need to drive and intelligent modules. "Hao 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
