  • Patent number: 9728686
    Abstract: A light emitting device and a method of fabricating the same is provided. The device includes an LED chip having a first main surface, a second main surface opposing the first main surface, and one or more side surfaces extending between the first and second main surfaces. A reflective side layer surrounds the one or more side surfaces of the LED chip. The reflective side layer has a first main surface and a second main surface opposing the first main surface extending in a first direction, and an opening extending between the first and second main surfaces in a second direction substantially perpendicular to the first direction. The opening surrounds the chip. A phosphor film overlies the first main surface of the chip and the first main surface of the reflective side layer. At least one electrode is disposed on the second main surface of the chip.
