The COB light source is a high-efficiency integrated surface light source technology in which the LED chip is directly attached to a high-reflection mirror metal substrate. This technology eliminates the bracket concept, electroless plating, no reflow soldering, and no patching process, so the process is reduced by nearly three points. One of them, the cost is also saved 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 external dimensions of the light source can be designed according to the product outline structure.
Cob light source characteristics
Product features: cheap and convenient
Electrically stable, circuit design, optical design, heat dissipation design is scientific and reasonable;
The use of heat sink process technology ensures that the LED has an industry-leading heat lumen maintenance rate (95%).
It is convenient for secondary optical matching of products and improves lighting quality.
High color, uniform light, no spot, healthy and environmentally friendly.
The installation is simple, the use is convenient, the design difficulty of the lamp is reduced, and the processing of the lamp and the subsequent maintenance cost are saved.
Cob light source manufacturing process
The COB Chip On Board (COB) process first covers the wafer placement point with a thermally conductive epoxy resin (usually an epoxy resin doped with silver particles) on the surface of the substrate, and then places the silicon wafer directly on the surface of the substrate. The heat treatment is performed until the silicon wafer is firmly fixed to the substrate, and then the electrical connection is directly established between the silicon wafer and the substrate by wire bonding.
Introduction to LED light sourceThe LED light source is a light source (LED) that is a light source of the illuminant. Light-emitting diodes were invented in the 1960s, and in the following decades, their basic use was as an indicator light for electronic devices such as tape recorders.
This bulb has the characteristics of high efficiency and long life, and can be used continuously for 100,000 hours, which is 100 times longer than ordinary incandescent bulbs. Scientists predict that in the next five years, this kind of light bulb is likely to become the mainstream of next-generation lighting.
