Abstract
A method for manufacturing light emitting elements is described and includes providing an un-coated light converting platelet. The un-coated light converting platelet has a top surface, a bottom surface, and side surfaces. A plurality of LED dies is provided. Side surfaces of the un-coated light converting platelet are coated with an at least partly reflective material to form a coated light converting platelet. The coated light converting platelet is separated into light converting tiles. An outline of the light converting tiles substantially corresponds to an outline of one of the plurality of LED dies. The light converting tiles and the plurality of LED dies are assembled to form light emitting elements.
