Introduction to AC COB LED

AC COB (Chip on Board) LED is an advanced lighting technology that integrates multiple LED chips on a single substrate. This design offers several advantages over traditional LED lighting solutions. Firstly, it simplifies the lighting system by eliminating the need for a separate driver in some cases, as the AC COB LED can be directly connected to the AC power supply. This not only reduces the cost and size of the lighting fixture but also improves its reliability. Secondly, AC COB LEDs provide high luminous efficacy, which means they can produce more light with less energy consumption, making them more energy - efficient and environmentally friendly. Additionally, they offer better heat dissipation, longer lifespan, and more uniform light distribution, which are highly desirable features in various lighting applications such as indoor and outdoor lighting, commercial lighting, and decorative lighting.
