Important future development direction With the gradual maturity of the LED application market, users are increasingly demanding the stability and reliability of their products. Especially under the same conditions, they are always pursuing lower power consumption and more competitive products.
Cob integrated packaging technology directly encapsulates multiple LED chips on a metal substrate, and directly dissipates heat through the substrate, which not only reduces the manufacturing process and cost of the bracket, but also has the advantage of reducing heat dissipation. Therefore, it has become the main push of many large manufacturers. An LED lighting package technology. The COB package family offers a wide range of lumens and a very high level of efficacy for a wide range of lighting applications.
In my opinion, COB light source has five outstanding advantages: 1, high luminous efficiency, high color rendering index, RA80, light efficiency is 100-120lm / W; 2, thermal conductivity, metal substrate series heat dissipation performance is significantly better than ceramic COB Light source; 3, product design flexibility, can change the original product chip string according to customer needs; 4, cost-effective advantages, can effectively reduce the manufacturing cost of the lamp; 5, complete power, covering 3W to 100W, can be applied All kinds of lighting products.
According to statistics, the current COB-packaged bulbs already occupy a market share of 40 to 50 LED bulbs, and the ratio is expected to gradually expand. The market has begun to gradually accept COB light source, no longer in a wait-and-see state, and COB light source has outstanding advantages such as good heat dissipation performance and high cost performance, and is an important development direction of LED packaging in the future.
Compared to SMD SMD packages and high power packages, COB packages offer significant advantages. In terms of performance, through reasonable design and construction of optical lenses, COB light source can effectively avoid spot light and glare, and can also effectively improve the color rendering index of the light source by changing the chip combination; in application, the COB light source makes the lamp Installation and production is simpler and more convenient, and can also improve the pass rate of finished lamps.
In summary, we can easily see that COB light source series products are one of the important development directions of LED lighting in the future.
