What is COB?

In electronic products, COB refers to Chip on Board. COB refers to a packaging technology, which is a packaging method that directly mounts LED chips on a circuit board.

This leads to a basic approach to LED construction, leaving only the LED chip, yellow phosphor overlay and connection pads. This type of LED is sometimes called a flip chip.

Unlike ordinary SMD LEDs, which have a lamp bead holder to package the LED chip and cover the phosphor coating, COB LED simplifies the design by removing unnecessary components.

What is COB LED Strip?

COB, is a technology that directly mounts LED chips onto a flexible PCB board, resulting in a COB LED light strip consisting of a row of chips packaged on a flexible board.

These chips are flip-chip, then the encapsulation glue containing phosphor is directly coated on the surface of the chip. The glue interacts with the light emitted from the surface of the chip, refracts and reflects it, and uniformly produces light of various colors.

Because of this unique packaging method, COB LED strips are also called seamless spotless LED strips. Therefore, the light emitted by the COB LED strip is very uniform without any dark areas.

Advantages of COB LED Strip

Made from non-toxic materials and recyclable, the COB LED strip is an eco-friendly lighting choice.

COB LED strips generate less heat than traditional light sources because COB LED strips are a single large LED chip mounted directly on a circuit board, helping to reduce heat and improve safety.

COB LED strip light consumes less energy than traditional light sources. Making it an environmentally friendly and cost-effective option.

Compared with traditional LED strp lights, the light emitted by COB LED strip is more uniform and consistent.

COB LED strips are available in a variety of color temperatures, including warm white, neutral white, cool white, RGB and RGBW, also other colors.

They are usually easy to install, just peel off the 3M adhesive and stick them to the installation surface. Of course, you can also choose accessories to install, which is helpful for heat dissipation.

COB LED strip can be bent and shaped to fit any space, and you can cut the strip to fit your needs and can be cut to fit specific lengths.

COB LED strips last longer than traditional light sources, which means over time, which means you won’t need to spend a lot of time and money on maintenance.
