For explosion-proof lighting, COB, DOB, and SMD refer to different types of LED technologies used to enhance the lighting performance, efficiency, and durability in hazardous environments.
Each of these LED technologies has its advantages depending on the specific lighting requirements and the environment in which the explosion-proof lighting is used.
COB
Best for powerful, uniform light output over large areas.
DOB
Integrates the driver onto the board, simplifying the design and enhancing reliability.
SMD
Provides flexibility in design with a wide beam angle, commonly used for general lighting applications.
COB - Chip on Board
COB refers to a method of LED packaging where multiple LED chips are mounted directly onto a substrate to form a single lighting module.
- Key Characteristics
- Produces a uniform, bright light with fewer visible points of light (compared to traditional LEDs).
- High efficiency and low heat generation, making it ideal for explosion-proof lighting applications.
- Suitable for large-area lighting due to its concentrated and powerful light output.
DOB - Driver on Board
- DOB refers to an integrated technology where the LED driver is built directly onto the LED circuit board.
- Key Characteristics
- Simplifies the design by eliminating the need for a separate driver component, making the fixture more compact.
- Often used in explosion-proof lighting to reduce the number of components, which can increase reliability and reduce costs.
- Typically provides consistent power to the LED chips, improving the overall longevity of the lighting.
SMD - Surface-Mounted Device
- SMD refers to LEDs that are mounted directly onto the surface of a printed circuit board (PCB).
- Key Characteristics
- Provides a wide beam angle and is more flexible in design than COB.
- Offers high brightness and is commonly used in explosion-proof lighting for area illumination and flexibility in design.
- SMD LEDs are more widely used in modular lighting designs due to their versatility.
