A point source LED chip is a type of LED chip that emits light from a single point, which provides more focused and directional lighting. It is often used for applications such as flashlights, automotive lighting, and display backlighting. The design of point source LED chips can vary depending on the specific application, but they typically consist of a small semiconductor die placed on a ceramic substrate with wire bonds connecting the die to the substrate. The die is encased in a transparent epoxy or lens to protect it and help direct the light output.
