As LED technology advances rapidly, AC-DOB (Direct on Board) and AC-COB (Chip on Board) have become two prominent integrated driver designs in the LED lighting industry. Both designs offer unique benefits in terms of cost, compact design, efficiency, and light quality, positioning them to lead the future of LED lighting.
AC-DOB (Direct on Board)
AC-DOB integrates the LED driver directly onto the circuit board, allowing the fixture to connect directly to an AC power source without the need for a separate driver module. This design reduces overall costs and fixture size, meeting the market’s dual demands for affordability and space efficiency. With its streamlined and efficient design, AC-DOB has found widespread application in general lighting and lower-power applications. However, high-power applications remain challenging due to the need for enhanced heat dissipation and durability in AC-DOB designs.
AC-COB (Chip on Board)
In contrast, AC-COB packages multiple LED chips directly on a single module, providing higher luminous efficiency and lower thermal resistance. AC-COB creates a more uniform light source, making it ideal for high-brightness applications such as commercial lighting, display lighting, and outdoor lighting. While AC-COB offers high efficiency and lower heat requirements, there is still room for improvement in addressing flicker control and extending lifespan.
The Necessity and Future of Circuit Protection
As AC-DOB and AC-COB technologies gain popularity, ensuring the safety and reliability of LED lighting systems has become a focal point. These designs bring significant advancements in integration and efficiency but also raise the bar for circuit protection. Traditional circuit protection solutions often fall short of meeting the high surge protection, compact size, and stability demands of AC-DOB and AC-COB. Addressing these needs requires circuit protection products that balance compact design with high-performance protection.
