    摘要： In a method for fabricating a flip-chip light emitting diode device, epitaxial layers (14, 114) are deposited on a growth substrate (16, 116) to produce an epitaxial wafer. A plurality of light emitting diode devices are fabricated on the epitaxial wafer. The epitaxial wafer is diced to generate a device die (10, 110). The device die (10, 110) is flip chip bonded to a mount (12, 112). The flip chip bonding includes securing the device die (10, 110) to the mount (12, 112) by bonding at least one electrode (20, 22, 120) of the device die (10, 110) to at least one bonding pad (26, 28, 126) of the mount (12, 112). Subsequent to the flip chip bonding, a thickness of the growth substrate (16, 116) of the device die (10, 110) is reduced.

    摘要： At least two light emitting diodes emit a non-parallel light beam. A condensing system, operationally coupled with the light emitting diodes, receives the emitted non-parallel light beam and converts the received non-parallel light beam into a parallel light beam. A non-imaging concentrator includes an input surface which collects the parallel light beam, and an output surface, which includes phosphor material and outputs light.

    摘要： In a light emitting device, a light emitting chip (12, 112) includes a stack of semiconductor layers (14) and an electrode (24, 141, 142) disposed on the stack of semiconductor layers. A support (10, 10′, 110, 210) has a generally planar surface (30) supporting the light emitting chip in a flip-chip fashion. An electrically conductive chip attachment material (40, 41, 141, 142) is recessed into the generally planar surface of the support such that the attachment material does not protrude substantially above the generally planar surface of the support. The attachment material provides electrical communication between the electrode of the light emitting chip and an electrically conductive path (36, 36′) of the support. Optionally, at least the stack of semiconductor layers and the electrode of the light emitting chip are also recessed into the generally planar surface of the support.

    摘要： First and second light emitting diode (LED) arrays, which each includes a corresponding number of LED dies, are disposed on a substrate proximately and substantially parallel to one another. Each pair of substantially paralleled LED dies of the first and second arrays is covered by substantially transparent optical encapsulant. The optical encapsulant is one of covered by a reflective layer for a UV to visible spectral region and shaped for total internal light reflection. The substrate is diced along an axis extending in parallel and between the first and second LED arrays.
