It is a new packaging method different from DIP and SMD packaging technology. It has obvious advantages in product stability, luminous effect, durability and energy saving. Based on the excellent performance advantages of COB, COB is widely used in commercial lighting, industrial lighting and vehicle lighting.

COB products are mainly used in the commercial lighting market. With the improvement of technology, the performance of high-power COB products tends to be stable. Recently, COB products are gradually used in outdoor lighting, including LED industrial and mining lamps, street lamps and other markets. Because high power LED and COB LED have product design advantages and high light intensity that are not available in medium power, they will enhance the competitive advantage of high-end lighting market.

In the high-end commercial lighting market, lighting is applied to the exhibition space of museums, art galleries and other markets, mainly including downlights, projection lamps and reflector lamps. Industrial lighting brings new opportunities to small and medium-sized COB enterprises. Among the many application fields of COB, commercial lighting, vehicle lighting and other fields have become extremely competitive due to the large number of enterprises involved. Throughout the LED packaging industry at this stage, some enterprises have carried out large-scale transformation, opened up the market in the field of general lighting, sought diversified development, and obtained new high gross profit growth points; Some enterprises also focus on the product upgrading in the LED packaging field, and win out of the Red Sea by optimizing the product performance and quality.
