1. Blue moon COB LED downlight production efficiency advantage
The production process of Blue moon COB LED downlight is basically the same as the traditional SMD production process. The efficiency of die bonding and wire bonding is basically the same as that of SMD packaging. However, in terms of dispensing, separation, spectroscopy, and packaging, Blue moon COB LED downlight The efficiency is much higher than that of SMD products.
Traditional SMD packaging labor and manufacturing costs account for about 15% of the material cost, and Blue moon COB LED downlight labor and manufacturing costs account for about 10% of the material cost. With COB packaging, labor and manufacturing costs can be saved by 5%.
2. Blue moon COB LED downlight low thermal resistance advantage
The system thermal resistance of traditional SMD packaging applications is: chip-die bond-solder joints-tin paste-copper foil-insulating layer-aluminum. The system thermal resistance of Blue moon COB LED downlight is: chip-solid crystal glue-aluminum. The system thermal resistance of the COB package is much lower than that of the traditional SMD package, which greatly improves the life of the LED.
3. Light quality advantage
In traditional SMD packaging, multiple discrete devices are pasted on a PCB board to form a light source assembly for LED applications in the form of patches. This approach has problems of spot light, glare, and ghosting. The Blue moon COB LED downlight is an integrated package and a surface light source. The advantage is that the viewing angle is large and easy to adjust, which reduces the loss of light refraction.
