With the rapid development of LED lighting technology, DOB (Diode on Board) is gradually replacing the traditional COB (Chip on Board) technology with its excellent optical performance, high reliability and flexible design concept, and has become the preferred solution for high-end lighting, commercial space and industrial applications.
I. DOB vs. Traditional COB:
Higher reliability, pressure and impact resistance
In traditional COB, PCB bending may cause chip damage during transportation or installation. DOB improves the packaging structure to enhance pressure resistance and impact resistance, reduce damage caused by external forces, and ensure stable performance of products under harsh conditions.
II. Design concept of DOB: intelligent, flexible and efficient
Highly integrated to improve light efficiency and brightness
DOB integrates multiple LED chips directly on the PCB board, reducing light energy loss and achieving higher brightness and light efficiency (up to 150lm/W or more), while reducing system complexity, saving space and cost.
Take user needs as the core and flexibly adapt to different scenarios
Ultra-thin and flexible design: suitable for hidden installation, such as cabinet lights, advertising light strips, etc.
Intelligent dimming compatibility: compatible with DALI, 0-10V and other protocols, easy to integrate into intelligent lighting system.
Optimize optical performance and restore true color
Through precision optical design, DOB can provide high color rendering index (CRI≥95) and reduce glare to ensure natural and soft light, which is suitable for high-end retail, medical surgical lamp and other scenarios with high requirements for color authenticity.
III. Extensive application scenarios of DOB
High-end lighting
Museums and art galleries: High color rendering (Ra>95) accurately restores the color of artworks.
Jewelry stores, luxury store Windows: uniform and no glare lighting to enhance the texture of goods.
Commercial space lighting
Shopping malls, hotels and restaurants: color temperature can be adjusted to create a comfortable atmosphere.
Exhibition stand: high brightness + modular installation, to create personalized lighting effects.
Industrial and outdoor lighting
Factories and warehouses: high illumination, long life, reduce maintenance costs.
IV. Future trend: DOB leads the new direction of lighting
With the maturity of Mini/Micro LED, driverless design (high voltage AC direct drive) and other technologies, DOB will further expand in ultra HD display, automotive lighting, UV curing and other fields, and promote the LED industry to a more integrated and intelligent direction.
Choose DOB, and choose a more efficient, reliable and flexible lighting future!
