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.
Claims4
A method for manufacturing light emitting diode devices comprising the steps of:
- preparing a substrate aggregation having a plurality of divisions;
- mounting a plurality of LEDs on the substrate aggregation at the divisions;
- forming a transparent layer on the substrate aggregation;
- removing the transparent layer between adjacent divisions to form an individual transparent layer at each of the divisions and to form a groove around the individual transparent layer;
- filling the groove with a reflector material to form a reflector layer;
- and
- cutting the reflector layer and the substrate so as to form a reflector film on the outside wall of the individual transparent layer, thereby forming a plurality of LED devices.
