[0002] The LED chips in the COB light source body are closely arranged on the substrate, and the spacing between the chips is small. Since multiple chips are closely arranged and emit light together, the COB light source body can provide a uniform lighting effect. Compared with a single LED, it will not have obvious light spots, and the lighting range is more uniform and soft.
