Top 10 COB LED Package Manufacturers in the World

In recent years, the smart lighting market has been in a stage of rapid development. Well-known manufacturers such as Signify, Opple Lighting, and NVC Lighting have continuously launched smart lighting products, and COB technology has also been widely used in the smart lighting market. This article lists the top 10 COB LED package manufacturers in the world.

Explanation of COB LED package

COB, chip-on-board, is a new packaging method different from SMD(surface mount) packaging technology. Specifically, the bare chip is adhered to the PCB with conductive or non-conductive glue, and then wire bonding is performed to realize its electrical connection, and the chip and the bonding wire are encapsulated with glue.

Strengths of COB LED package

Compared with SMD LED, COB LED has the following advantages:
1. High packaging efficiency and cost saving
The COB packaging process is not much different from the SMD production process, but the packaging efficiency of COB packaging in dispensing, separation, light splitting and packaging is much higher.

The COB packaging process is not much different from the SMD production process, but the packaging efficiency of COB packaging in dispensing, separation, light splitting and packaging is much higher.

2. Advantages of low thermal resistance
The system thermal resistance of the COB package is much lower than that of the traditional SMD package, so the COB packaged LED lamps have a longer service life.

3. Light quality advantages
SMD packaging pastes multiple discrete devices on the PCB to form a light source component for LED applications in the form of patches. This method has the problems of point light, glare and ghosting.

The COB package is an integrated package and a surface light source with a large viewing angle and easy adjustment, which can reduce the loss of light refraction.

4. Application advantages
The application of COB light source is very convenient, and it can be directly applied to lamps without other processes. However, the traditional SMD package light source still needs to be patched first, and then fixed on the PCB board through reflow soldering.

Conclusion

With the popularization of COB technology, not only in the commercial lighting market, but also in recent years, the trend of non-main lamp design has gradually introduced COB products into the home lighting market. More and more families start to use downlights, spotlights and other lighting products, and these products are the main application lamps of COB products. This is expected to further drive the market demand for COB packaging.

FAQ about COB LED package manufacturers

COB, chip-on-board, is a new packaging method different from SMD(surface mount) packaging technology.

COB LED package is the chip packaged directly onto the board. It improves the light efficiency and reduces the light loss.
While SMD LED is LED lamp bread with a single patch. And the light emitting diode attached directly to the surface.
