1. An illumination device comprising:

  • a polymeric binder;

    suspended within the polymeric binder, a bare-die light-emitting element having (i) a first face, (ii) a second face opposite the first face, (iii) at least one sidewall spanning the first and second faces, and (iv) disposed on the first face of the light-emitting element, at least two spaced-apart contacts each having a free terminal end; and

    a frame (i) having a bottom surface, (ii) having a top surface opposite the bottom surface, (iii) having a thickness spanning the top and bottom surfaces, and (iv) defining an aperture (a) extending fully through the thickness and (b) having a sidewall, the top surface of the frame surrounding the aperture,wherein the light-emitting element is disposed within the aperture of the frame such that (i) the second face of the light-emitting element is opposite the bottom surface of the frame, (ii) the sidewall of the aperture redirects light emitted from the light-emitting element away from the bottom surface of the frame, (iii) the free terminal ends of the contacts of the light-emitting element are (a) not covered by the polymeric binder and (b) available for electrical connection, and (iv) a bottom exposed surface of the illumination device includes at least a portion of the first face of the light-emitting element.
