Advantages and disadvantages of COB chips

The advantages and disadvantages of COB chips. The cob light source is the high-efficiency integrated surface light source technology in which the LED chip is directly attached to the mirror metal substrate with high reflectivity. This technology eliminates the concept of brackets, no plating, no reflow soldering, and no mounting process, so The process is reduced by nearly one-third, and the cost is also reduced by one-third. The COB light source can be simply understood as a high-power integrated surface light source, and the light-emitting area and size of the light source can be designed according to the product shape and structure. Product features: electrical stability, scientific and reasonable circuit design, optical design, and heat dissipation design; the use of heat sink technology ensures that the LED has an industry-leading thermal lumen maintenance rate (%). It is convenient for the secondary optical matching of the product and improves the lighting quality. ; High color rendering, uniform luminescence, no spot, healthy and environmentally friendly. The installation is simple and easy to use, which reduces the difficulty of lamp design and saves the cost of lamp processing and subsequent maintenance. Disadvantages: COB high-power LED integrated chip is not stable yet prone to light decay.
