COB Led Chip is a type of LED that is made up of multiple LED chips packaged together onto a single board. This allows for greater efficiency and brightness compared to traditional LED bulbs. COB Led Chip is typically designed to be used as a light source in a variety of lighting applications, such as indoor and outdoor lighting, automotive lighting, and backlighting. These come in different shapes and sizes to suit various applications, from small LED chips used in smartphones and laptops to larger chips used in streetlights and industrial lighting fixtures.
