What are Chip-on-Board LEDs?
COB technology is all about mounting multiple LED chips directly onto a substrate to form a single module. This approach increases the packing density of the LEDs, which means more lumens per square inch and less heat. That makes COB LEDs super-efficient and super-compact.
The Functionality of Chip-on-Board LED Technology
COB LEDs are great for many applications because they give off a lot of light that is spread out evenly and is not too bright. The chips are really close together, so the light looks more natural and you can’t see the individual LEDs. The chips are made of special materials that turn electricity into light, which is called electroluminescence. LEDs are really good for saving energy.
LED Array Packing Density: DIP vs. SMD vs. COB
| Feature | DIP LEDs | SMD LEDs | COB LEDs |
| Packing Density | Low | Medium | High |
| Light Output | Moderate | High | Very High |
| Size | Larger | Compact | Most Compact |
| Heat Dissipation | Less Efficient | Efficient | Most Efficient |
| Application | General Lighting | Versatile Lighting | High-Performance Lighting |
COB LEDs are super efficient, using less power to produce brighter light compared to other LED setups. This is especially important in battery-powered devices, where you want to get the most out of your battery. COB LEDs also have better thermal management, which makes them last longer and be more reliable.
LED technology has revolutionized the lighting industry with its superior efficiency and longevity. Among the various innovations, Chip-on-Board (COB) LEDs stand out due to their unique assembly and capabilities.
