COB LED Strips: Unpacking the Basics

What is COB LED and What is COB LED strip


COB (Chip-on-Board) LED technology involves mounting multiple LED chips directly onto a substrate to form a single module. The diodes are packed tightly, minimizing the space between them, resulting in a light source that resembles a lighting panel rather than individual LEDs.

A COB LED flexible strip is a type of LED light that uses a single, large LED chip to produce light. The LED chip is mounted directly on a flexible PCB, which makes the strip easy to bend and install.

The Manufacturing Process of COB LED Flexible Strips

The manufacturing process of flexible COB LED strips involves placing multiple LED chips on a flexible substrate and directly applying phosphor and encapsulant. This results in an LED strip that boasts high luminous efficiency, a large heat-dissipating area, and an impressively small size.
