The COB LED strip encapsulates the chip on a flexible board.
Chips mostly use flip-chips, which are linearly solid-bonded on the PCB, and then a layer of packaging glue mixed with phosphor is directly dropped on the surface of the chip.
The light emitted by the chip is refracted, reflected, and interacted with the phosphor inside the encapsulating gel. The gel uniformly emits light of different colors and color temperatures.
It is a new type of process technology, based on the SMD led strips with further evolution.
Compared to the regular SMD(Surface Mounted Devices) LED Strip Lights,the highlights of our COB(Chip on Board) LED Strip Lights are as follows:
- Brighter and more uniform light without spots
- Lower power consumption for energy saving,higher light efficiency(110LM/W)
- Higher Color Rendering Index(CRI 90+) benefits reflection of true color
- Soft light,no glare,no harm to your eyes
- Safe for children and pets
But COB led strips can become very uniform without adding diffuser.
In this way, a lot of material costs and labor costs can be saved.

The COB led strips have a linear light-emitting surface due to their high chip density, while the SMD led strips can see obvious light spots and dark areas.
as we know, this dark area and light spot can be solved by adding aluminum profiles and diffusers
