COB LED technology has been making waves in the world of lighting, offering promising advancements in efficiency, brightness, and versatility. In this article, we delve into the intricacies of COB LEDs, examining their features, advantages, drawbacks, and common misconceptions.
What is a COB LED?
COB, or Chip-on-Board, LED is a type of LED technology where multiple LED chips are packaged together onto a single substrate. This arrangement allows for higher light output and better thermal management compared to traditional LED packages. COB LEDs typically feature a compact design and offer uniform light distribution, making them ideal for various lighting applications.
