Best 10 Miniature Cob Manufacturers in The World

Introduction to Miniature COB

Miniature Chip - on - Board (COB) technology is a revolutionary approach in the field of lighting and electronics. COB involves directly mounting multiple LED chips onto a substrate, which eliminates the need for individual packaging of each chip. Miniature COB takes this concept further by reducing the size of the COB module while maintaining high - performance levels.

These miniature COB modules offer several advantages. They have a high luminous density, which means they can produce a large amount of light from a very small area. This makes them ideal for applications where space is limited, such as in automotive headlights, high - end spotlights, and mobile device flashlights. Additionally, they have excellent thermal management capabilities, as the direct mounting of chips on the substrate allows for efficient heat dissipation. This results in a longer lifespan and more stable performance of the lighting source.

Now, let's take a look at the top 10 manufacturers of miniature COB in the world.
