    Abstract: A light emitting device includes a first light emitting cell and a second light emitting cell. Each light emitting cell includes a first semiconductor layer, a second semiconductor layer, and an active layer between the first and second semiconductor layers. The second semiconductor layer of the second light emitting cell has an exposed surface. A transparent bonding layer is located between the first and second light emitting cells. A hole is formed on the first and second light emitting cells and the transparent bonding layer. A first route metal is located on a sidewall of the hole and electrically coupled to the second semiconductor layer of the first light emitting cell and the first semiconductor layer of the second light emitting cell. The active layer of the second light emitting cell has an area greater than the active layer of the first light emitting cell.

    Abstract: A light-emitting diode (LED) package comprising a carrier, an LED chip and a phosphor glue is provided. The carrier has a recess, an upper surface, and a ring-shape rough surface connected to a top edge of the recess. The LED chip is disposed within the recess. The phosphor glue fills up the recess and over the upper surface of the carrier. An edge of the phosphor glue contacts the ring-shape rough surface.

    Abstract: A light emitting diode device includes a substrate, a light emitting diode chip, an optical lens and an adhesive interface layer. The light emitting diode chip is electrically connected with the substrate. The optical lens has an accommodation cavity to enclose the light emitting diode chip on the substrate, wherein the accommodation cavity includes a micro diffusion structure on an inner wall thereof. The adhesive interface layer is filled within the accommodation cavity of the optical lens.
