Since 2015, due to its heat dissipation, light efficiency and other issues have been further resolved, the market environment can be applied more, the COB market is a good voice, industry analysts, 2015 COB product sales accounted for 30% of the overall light source about.
However, the road to COB development is not smooth. In the LED industry, although the COB light source has advantages in the LED commercial and other market segments, SMD patch is still the mainstream of the market. "This mainstream trend may not change in a short period of time." Zhang Luhua, marketing director of Smale Tell the high-tech LED.
Entering 2016, LED companies are once again active in the capital market. LED packaging companies such as Xuyu Optoelectronics, Liyang, Jingke Electronics, and Shengpu Optoelectronics have made new efforts in the new three boards. At a closer look, these companies all include the main business of COB without exception.
Domestic packaging Daxie Hongli Optoelectronics (300219.SZ) is also unambiguous in dealing with COB. Last year, it conducted a series of technical exchanges for COB. COB's technology research and development is still improving, and its COB product LM004 (80W) has obtained the LM-80 10,000-hour test report.
Recently, Purui Optoelectronics, Jingke Electronics, etc. have released new COB products, all of which have announced their main high-efficiency effects.
At the Guangya Exhibition in June this year, Jingke Electronics concentrated on AC COB, 160lm/W high-efficiency COB, and the high-impact COB series products with > 95, and related applications. It is understood that the newly launched products While improving the light efficiency, it also reduces heat loss and reduces thermal resistance, thereby improving product reliability and increasing the light quality of the lighting product.
“High light quality, high light efficiency, small size and high density COB are important development trends this year,†said Wang Gaoyang, deputy general manager of Hongli Optoelectronics. This is the inevitable result of light quality and light efficiency and cost.
Gaogong LED learned that Hongli Optoelectronics' Jiangxi production base also has planned COB capacity, which is complementary to the new COB method.
According to the data, in the global high-end commercial lighting market in 2016, 40% and 75% of the most widely used downlights and track spotlights use COB light sources (according to the number of lamps, mainly based on COB with power below 30W). ).
"COB's share will continue to increase." In Wang Gaoyang's view, AC COB, high-efficiency, small-size and high-density products are the focus of COB development this year.
In fact, in terms of LED market capacity and demand, whether it is SMD patch, COB light source, or CSP, there is room for development. Finding the direction of development may be more important than technological progress.
