    摘要: The light-emitting device includes a light source and a gradient index (GRIN) element. The GRIN element has a cylindrical refractive index profile in which the refractive index varies radially and is substantially constant axially. The GRIN element includes a first end surface opposite a second end surface and is characterized by a length-to-pitch ratio. The GRIN element is arranged with the first end surface adjacent the light source to receive light from the light source, and emits the light from the second end surface in a radiation pattern dependent on the length-to-pitch ratio. Since the radiation pattern depends on the length-to-pitch ratio of the GRIN element, LEDs with different radiation patterns can be made simply by using GRIN elements of appropriate lengths.

    摘要: A reflection-based optical encoding apparatus for the detection of position and/or motion of a mechanical device includes an encoding medium having at least a first reflective portion, and an encoder housing having a light-emitting source and a light-detecting sensor embedded within, the encoder housing being placed in proximity to the encoding medium such that a functional light path can be established from the light-emitting source to the light-detecting sensor via the first reflective portion of the encoding medium. The encoder housing includes a first flat facet positioned between the light-emitting source and the encoding medium, the first flat facet having a first angle relative to a common geometric plane such that light passing from the light-emitting source to the encoding medium is refracted along a first angled path in a manner that the refracted light strikes a desired location of the encoding medium.

    摘要: An encoder having a code strip and an emitter-detector module is disclosed. The code strip includes alternating reflective and opaque stripes. The emitter-detector module includes a housing, a lens insert, a light source and a photodetector. Light from the light source illuminates the code strip, and light reflected from the code strip is incident on the photodetector. The lens insert includes a lens that processes light generated by the light source either before the light reaches the code strip or after the light is reflected from the code strip. The lens insert mates with the housing to position the lens at a predetermined point relative to the light source or the photodetector. The housing will accept a plurality of lens inserts, each lens insert having a different lens from the others of the lens inserts.

    摘要: A method of interconnecting bond pads on a semiconductor die to leads of a package is disclosed. The method includes placing a connector over each bond pad and its corresponding lead. The connector is one of a plurality of ganged connectors. The method also includes electrically connecting the connector to the bond pad and the lead and singularizing the connector from the plurality of ganged connectors. Such a method of interconnection has the advantage of simultaneously interconnecting multiple bond pads to leads. In a preferred embodiment, light-emitting diodes (LEDs) are manufactured using the method. A PCB is etched to produced lead pairs of the LEDs. A semiconductor die is attached to a first lead of each lead pair. Ganged interconnects are aligned with and tagged onto the dies and the second leads of the lead pairs, thereby electrically connecting them. After tagging, the interconnects are singularized. An encapsulant is applied on each die and interconnect. Each die, interconnect and lead pair are then separated to form individual LEDs.
