Abstract
A plurality of LEDs are mounted on a substrate aggregation, a transparent layer is formed on the substrate aggregation. The transparent layer between adjacent divisions is removed to form an individual transparent layer and to form a groove around the individual transparent layer. The groove is filled with a reflector material to form a reflector layer. The reflector layer and the substrate are cut so as to form a reflector film on the outside wall of the individual transparent layer, thereby forming a plurality of LED devices.
