6 Kinds of LED Chip Technology


Since LED technology is used in various applications, LED manufacturers have developed six kinds of LED chips that meet a product’s needs. What are the six types of LED chips manufacturers use in their products?

  • LED SMD or Surface Mounted Diode
  • LED COB or Chip on Board
  • MCOB (Multiple Chips on Board) LEDs
  • Mini LEDs and Micro LEDs
  • High Power LEDs
  • Flip-chip LEDs


SMD (Surface Mounted Device) LEDs:

SMD LEDs are one of the most common types of LED chips used today. They are mounted directly onto the surface of the circuit board, allowing for efficient heat dissipation and compact design. SMD LEDs come in various sizes, such as 3528, 5050, and 5630, indicating their dimensions. They are widely used in LED light bulbs, panels, and strip lights.


COB (Chip on Board) LEDs:

COB LEDs consist of multiple LED chips bonded directly to a substrate to form a single module. This design allows for a higher density of LED chips, resulting in a more intense light output from a single point, which is excellent for improving light uniformity and reducing glare. COB LEDs are commonly used in LED spotlights, floodlights, and downlights.


MCOB (Multiple Chips on Board) LEDs:

MCOB technology involves placing multiple COB LEDs on the same board. This approach further enhances light output and efficiency, making MCOB LEDs suitable for high-brightness applications such as street lighting and industrial lighting.


High Power LEDs:

High power LEDs are designed to handle more electrical power and produce more light output than standard LEDs. They typically require additional heat management solutions to deal with the increased heat output. High power LEDs are used in applications where intense brightness is needed, such as automotive headlights, searchlights, and high-bay lighting in industrial settings.


Mini LEDs and Micro LEDs:

Mini LEDs and Micro LEDs are emerging technologies that offer superior brightness, contrast, and energy efficiency compared to traditional LED types. Mini LEDs are smaller than conventional LEDs but larger than Micro LEDs. Micro LEDs, on the other hand, are tiny, allowing for extremely high pixel densities in displays, which improves resolution and image quality. These technologies are particularly promising for advanced display applications, including televisions, smartphones, and wearable devices.


Flip-chip LEDs:

Flip-chip LEDs invert the LED structure, placing the light-emitting layer on top. This design improves heat dissipation and allows for a more direct light path, enhancing light output and reliability. Flip-chip technology is often used in high-performance LED lighting and automotive lighting.

Each type of LED chip has its unique advantages and is suited to specific applications based on factors like brightness, energy efficiency, color rendering, and the physical size of the LED fixture. The choice of LED chip type is crucial in achieving the desired performance and efficiency in any given application.
