After the LED general lighting market experienced a battle in the Red Sea, the entire industry appeared to be somewhat depressed. Many domestic lighting manufacturers could not escape the "bad luck." After entering this year, various companies began to adjust their strategic layout, and they have turned to the high-end market and LED segmentation market.
With the rapid growth of demand for commercial lighting and industrial lighting, the demand for COB products with excellent light performance has also grown rapidly, and has become the scent of the LED industry.
Wang Mengyuan , general manager of Zhonghao Optoelectronics, said that in the past two years, the COB market has maintained a growth trend. In 2015, COB product sales accounted for about 30% of the overall light source.
In 2016, the overall LED market is generally warming up, which is also a strong driving force for the development of the COB market.
Dr. Shao Pengrui, Technical Director of Jingtai Co., Ltd. believes that since the beginning of 2016, the entire LED market has been developing in a good direction. With the rapid growth of the penetration rate of the LED lighting market, the development of the COB market will gradually become more rational.
So, what is the reason why COB is so favored?
Liu Lin, the deputy general manager of the same party, believes that the COB market is improving. On the one hand, COB has been promoted for many years, and customers have become more and more accepting. On the other hand, the corporate brand effect has been recognized by customers.
Nowadays, the scale of the COB market continues to expand, and the demand for production is also growing. Various packaging manufacturers have said that the sales volume of COB in the first quarter of 2016 has increased significantly.
“The same three months COB capacity of the same side has increased by nearly 60% compared with the last three months of last year, and the turnover has increased by 30%--40%. The sales performance is considerable.†Liu Lin told Gaogong LED.
Wang Mengyuan also said that Zhonghao Optoelectronics' COB sales in the first quarter of 2016 increased two to three times compared with last year.
However, some insiders also suggested that the sales of COB in 2015 was not satisfactory. Although sales volume has increased significantly, sales have not increased.
It is understood that the price of COB products declined in 2015, and the competition among enterprises was fierce, which led to the phenomenon that “increment does not increase revenue†in the COB market.
In this regard, Wang Mengyuan said that this situation only occurred in the field of circulation lighting, and the sales growth in the high-end COB market is still quite obvious.
Recently, Purui Optoelectronics has carried out a comprehensive upgrade on the seventh generation of COB products, announcing the main high-efficiency. In fact, under the impetus of many new products, the high-efficiency COB market is also becoming more and more lively.
“More than just Purui Optoelectronics, major manufacturers such as OSRAM and Hongli Optoelectronics are already doing high-efficiency COB products, because ordinary light effects are no longer superior in the market, and high-efficiency COB can meet some special light source pairs. Volume and light requirements." Shao Pengrui said.
Wang Gaoyang , deputy general manager of Hongli Optoelectronics also proposed that “the current COB light source technology is more and more mature, and the market has a stronger demand for COB light source. The packaging manufacturers no longer stay in the initial technical solution stage, but turn to the pursuit of high The cost-effective stage of quality and high efficiency COB, the field of flip-chip COB light source with high performance and high quality performance."
As we all know, flip-chip COB is consistently considered as a trend in the future in the LED industry, but it takes a time to truly achieve mass production in the market. Of course, flip COB and formal COB have always been compared, and many people in the industry have different views on the two.
Liu Lin believes that the price of flip-chip is cheaper than the price of the dress. The range of customers accepted is mainly concentrated in the middle and high-end market. I believe that the flip-chip will slowly replace the application on the COB. The same side of the photoelectric has been insisting on the flip-chip COB market, has begun to volume shipments, and accounted for one-sixth of the total COB product shipments.
On the contrary, many people in the industry believe that flip-chip COB is difficult to replace the COB.
Shao Pengrui said that the formal wear market is also constantly developing. If it is only from the price comparison, the formal wear is more advantageous. In addition, if it is compared from the special application field, the flip-chip is more advantageous. However, I personally think that it is less likely that the reversed COB will replace the COB in the future, and the two will coexist.
Similarly, Wang Mengyuan also believes that the application of flip-chip in the traditional lighting field is not as good as the formal dressing. In the case of the same performance, the cost of flip-chip is higher; at the same price, the performance of flip-chip is not as good as the dressing. However, flip-chip is a trend, and technology will continue to improve and progress.
In general, whether flip-chip COB can replace the formal COB, it is an effective means to solve the current decline in package gross profit and seek new profit growth points.
