The application of COB LED in UV curing is mainly reflected in its high energy density and narrow spot characteristics, which gives it significant advantages in fields such as high-speed flexo printing.
Advantages of COB LED in UV curing
High energy density and narrow light spot: COB LEDs are arranged in an array, combined with optical design and heat dissipation technology, which can significantly improve the optical utilization efficiency and optical power density of the illuminated area, and are suitable for curing applications that require high energy density.
Environmental protection and safety: COB LED does not contain mercury, does not produce ozone, meets environmental protection requirements, and is suitable for curing scenarios with high environmental requirements.
Long life and low energy consumption: COB LED has a long service life and low energy consumption, which can significantly reduce operating costs and maintenance costs.
Specific application cases of COB LED in UV curing
High-speed flexo printing machine: In high-speed flexo printing machines, COB LED light source modules can provide high-energy-density ultraviolet light, which is suitable for high-speed and large-area curing requirements, significantly improving production efficiency.
Electronic component bonding: In the electronics industry, COB LED is used for bonding and coating curing of electronic components, such as PCB boards, magnetic heads, hard drives, etc., to ensure the stability and reliability of components.
Fiber optic connectors: In the production of fiber optic connectors, COB LED is used for coating and curing to improve the reliability and durability of the connector.
The difference between COB LED and DOB LED and their application differences in UV curing
Packaging method: The main difference between COB (Chip On Board) and DOB (Die On Board) lies in the choice of chip and substrate. COB usually adopts customized design, the manufacturing process is difficult, and is suitable for scenarios with high power requirements; while DOB is easier to achieve standardization and mass production.
Light performance: Due to the complex manufacturing process of COB, once manufacturing defects occur, the entire light source needs to be replaced, while DOB only needs to replace the failed device.
In summary, the application of COB LED in UV curing has significant advantages, especially in scenarios requiring high energy density and narrow light spot. Its environmental protection, safety and low energy consumption characteristics also make it widely used in many industries.
