Claim:
1. A light emitting device comprising: an LED chip having a first chip main surface, a second chip main surface opposing the first chip main surface, and one or more side surfaces extending between the first chip main surface and second chip main surface; a reflective side layer surrounding the one or more side surfaces of the LED chip, wherein the reflective side layer has a first reflective side layer main surface and a second reflective side layer main surface opposing the first reflective side layer main surface extending in a first direction, and an opening extending between the first reflective side layer main surface and the second reflective side layer main surface in a second direction substantially perpendicular to said first direction as seen in a cross section view of the device, wherein said opening surrounds the LED chip, and the reflective side layer is directly in contact with the LED chip; a phosphor film overlying the first main surface of the LED chip and the first main surface of the reflective side layer; a buffer layer between the phosphor film and the LED chip, wherein the buffer layer is directly in contact with the LED chip and the phosphor film; and at least one electrode disposed on the second main surface of the LED chip, wherein the buffer layer extends between the LED chip and the reflective side layer, and wherein each of the one or more side surfaces of the LED chip includes a first part in contact with the buffer layer and a second part in contact with the reflective side layer.
