Understanding COB LED Modules
What are COB LED modules?
COB LED modules, which stand for Chip-on-Board LED modules, are a big step forward in lighting. They have many LED chips placed on one base, creating a small and effective light source. This setup spreads light evenly, removing shadows and giving steady brightness.
The module has a special coating that changes blue light into different colours. This lets you pick the right light for your needs, like warm light for homes or cool light for factories. Their small size makes them great for tight spaces, like gadgets or screens.
Tip: COB LEDs last long because they handle heat well. The chips are fixed on the base, which helps cool them down and keeps them working longer.
How do COB LED modules work?
COB LED modules work by putting many LED chips together in one unit. These chips join forces to make bright, even light. The base holds the chips and helps get rid of heat. This keeps the module cool, even when used for a long time, making it last longer.
Here’s why this technology is special:
Compact Design: Many chips fit in a small space, saving room but still giving strong light.
Uniform Light Output: The light spreads evenly, cutting down on glare and shadows.
Thermal Management: Heat is removed well, keeping the module steady and reliable.
Specification/Innovation | Description |

COB LED modules use less energy than old-style bulbs. They turn more electricity into light, saving power. This means you get bright light but use less energy. Switching to COB LEDs can lower your bills and help the planet. They also cut down harmful gases, making them eco-friendly for homes and businesses.
Uniform light output
COB LED modules give steady and even light. The chips are placed in a grid, removing dark spots. A special coating helps colours look smooth and even. This makes them great for places needing bright, clear light. Examples include shop displays or taking professional photos.
Compact design
COB LED modules are small but powerful. Many chips fit on one base, saving space. They work well in small fixtures or tight areas. Compared to SMD LEDs, COB LEDs are more compact and manage heat better, as shown below:
Feature | COB LEDs | SMD LEDs |
|---|---|---|
Construction | Many chips on one base, tightly packed | Single chips on a board, separately packaged |
Size and Integration | Smaller, good for tight spaces | Different sizes, but bulkier |
Heat Management | Better heat control with base design | Uses board for heat control, less effective |
Effective heat dissipation
COB LED modules handle heat very well. Materials like aluminium or ceramic help cool them quickly. This keeps them from overheating, even when used for hours. Strong heat sinks make them last longer and work safely. They are tough and work well in hard conditions, making them a good choice for many uses.
Durability and longevity
COB LED modules are made to last a long time. They can work for 25,000 to 50,000 hours. This means fewer replacements, saving money and effort. Good heat control keeps them working well for years. Their small design also reduces chances of breaking. Whether in factories or gadgets, COB LEDs are reliable and strong.
