Description
The COB downlight is a type of lighting that has high quality, even light spots, and good color rendering.
The phrase COB means "chip on the board" or "integrated surface light source" in Chinese. It's a cutting edge LED packaging technique. It includes putting together and packaging many LED chips directly on the same substrate to make a surface that gives off a lot of light.

COB downlight vs. SMD downlight
| Features | COB downlight | SMD downlight |
| Light source form | Full surface light source, a single complete light emitting body | Multiple-point light source, composed of multiple dispersed light bulbs |
| Light spot effect | Excellent, smooth transition, no graininess, no multiple shadows | Average, if the lens design is not good, multiple light bulb shadows or uneven light spots may be seen |
| Glare control | Good, soft light, but requires deep-embedded anti-glare design | Depends on lens design, sometimes the brightness of a single light bulb is high, resulting in glare |
| Cost performance | Relatively high, superior performance | High, mature technology, low price |
| Applicable scenarios | Highlighting, high-end commercial, home (high light quality requirements) | Basic lighting, ordinary home, office (Pursuing cost-effectiveness) |
Applications
Home space: Living room, entrance hall, background wall with wall washing, creating a sense of sophistication.
Commercial spaces: Clothing stores, jewelry stores, museums, hotel lobbies, etc., are places that require precise and high-quality lighting.
