1. A light emitting element comprising:
at least one LED die comprising a top surface, a bottom surface, and side surfaces, wherein all of the side surfaces of the LED die are completely covered by an at least partly reflective layer; and
at least one light converting tile on the top surface of the LED die, the at least one light converting tile comprising a plurality of surfaces including a top surface, a bottom surface, and a plurality of side surfaces, wherein the at least partly reflective layer covers the side surfaces of the light converting tile except at least one of the plurality of side surfaces, and wherein the at least one of the plurality of side surfaces of the light converting tile that is not covered by the at least one partly reflective layer extends laterally beyond at least one of the side surfaces of the LED die.
