    摘要: A light emitting diode (LED) package includes a substrate, a light emitting diode (LED) die mounted to the substrate, a frame on the substrate, a wire bonded to the light emitting diode (LED) die and to the substrate, and a transparent dome configured as a lens encapsulating the light emitting diode (LED) die. A method for fabricating a light emitting diode (LED) package includes the steps of: providing a substrate; forming a frame on the substrate; attaching a light emitting diode (LED) die to the substrate; wire bonding a wire to the light emitting diode (LED) die and to the substrate; and dispensing a transparent encapsulation material on the frame configured to form a transparent dome and lens for encapsulating the light emitting diode (LED) die.

    摘要: Light-emitting semiconductor devices are provided with certain layers in an effort to produce increased luminous intensity when compared to conventional light-emitting devices. The light-emitting semiconductor device includes a light-emitting semiconductor; a first transparent layer disposed over the light-emitting semiconductor; a first wavelength-converting layer disposed over the first transparent layer, wherein an upper surface of the wavelength-converting layer is curved; and a second transparent layer disposed over the wavelength-converting layer, wherein an upper surface of the second transparent layer is curved or tapered.
