What is the difference between Cob LED chips and LED chips

1、 The definitions and structures of the two

LED bead: LED bead is a type of light-emitting diode composed of compounds of elements such as gallium, arsenic, and phosphorus. It has the advantages of small size, low power consumption, and long lifespan. LED beads are mainly composed of brackets, light-emitting chips, and transparent epoxy resin packaging.

COB LED chips: COB LED chips are a lighting technology that directly package and paste LED chips onto a PCB board, and then form circuit connections through integrated packaging on the substrate. Unlike LED beads, COB beads do not require the use of traditional lamp cups and reflective cups, thus having a simpler appearance and more efficient lighting effect.

2、 Performance characteristics of LED beads and COB beads

LED beads: LED beads have the advantages of low power consumption, long lifespan, environmental protection, and mercury free. They have rich color expression and can provide various lighting effects such as cold light and warm light. In addition, LED beads also have characteristics such as high brightness, small size, and vibration resistance, making them widely used in the field of modern lighting.

COB LED chips: Due to the direct packaging of LED chips on the PCB board, COB LED chips have higher light efficiency and more uniform brightness distribution. In addition, COB lamp beads also have a simple exterior design, making it easy to customize various shapes and sizes, providing more creative space for lighting designers.

3、 Application scenarios of LED beads and COB beads

LED beads: LED beads are widely used in various lighting occasions, such as indoor decoration, outdoor landscape, billboards, etc. Due to its small size, rich colors, and long lifespan, LED beads have become one of the mainstream products for modern urban landscape lighting.

COB LED beads: COB LED beads are widely used in high-end commercial venues, art exhibitions, museums, and other places that require high-quality lighting. Due to its high luminous efficiency and uniform brightness distribution, COB beads have become one of the popular choices in modern lighting technology.

4、 Overall

LED beads and COB beads each have their unique advantages and application scenarios. LED beads have the advantages of low power consumption, long lifespan, and environmental friendliness without mercury, making them suitable for various lighting occasions; COB lamp beads have the characteristics of high luminous efficiency, uniform brightness distribution, and simple appearance design, and are suitable for high-end commercial venues, art exhibitions, and other fields. When choosing lighting products, appropriate lighting technologies should be selected based on actual needs and scenarios.
