Description
Chip on Board, which is what COB stands for, means "chip on board" or "integrated surface light source" in Chinese. It's a cutting edge LED packaging technique.
Traditional LED beads (such as SMD): Each individual LED chip is separately encapsulated into a small bead, and then these small beads are soldered onto the circuit board.
COB technology: It involves directly integrating and packaging multiple LED chips on the same substrate to form a dense and complete light-emitting surface.

Applications
The following things make COB downlights stand out:
Very high light output and brightness: the level of integration of the chips is high, and there is more light per unit area. Because of this, COB downlights are often very bright and have a high lighting efficiency.
Uniform and perfect light spots: One of the best things about COB downlights is that they give off even, perfect light. The light it gives off is very soft and even because it comes from the surface. It makes very pretty, naturally changing light spots without any shadows when it shines on walls or things, which is a great visual effect. This is very important for events that need focused lighting and the creation of a mood.
High color rendering: A high color rendering index (CRI > 90 or even Ra > 95) is easy to get with good COB chips. This means it can show the true colors of things better, which makes it perfect for places that need to show colors accurately, like museums, art galleries, jewelry stores, clothing stores, hotels, and houses.
Great at getting rid of heat: the COB chip is directly connected to the substrate, and the substrate is closely joined to the downlight's heat sink. This makes it easier for heat to escape more quickly and directly, which helps the lamp last longer.
Small size, easy to control light distribution: The light source is a single unit, so it can be carefully combined with a reflector cup or lens to control the angle of light emission. This makes light concentration more effective and waste less light.
