  • Patent number: 10062822
    Abstract: A light-emitting diode package structure, a light-emitting device and a method of making the same are provided. The light-emitting diode package structure includes an insulating base, a first conductive unit, a second conductive unit and at least one light-emitting diode chips. The first conductive unit is disposed on the insulating base. The second conductive unit is disposed on the insulating base and separated from the first conductive unit. The at least one light-emitting diode chips is electrically connected to the first conductive unit and the second conductive unit. Further, the first conductive unit has a first groove, and an outer surface thereof is divided by the first groove into two separated parts. In addition, the second conductive unit has a second groove, and the outer surface thereof is divided by the second groove into two separated parts.

  • Publication number: 20120223231
    Abstract: The instant disclosure relates to a proximity sensor having an electro-less plated optical shielding structure. The sensor includes a substrate panel having an emitter region and a receiver region; an emitter unit disposed on the emitter region and configured to emit electromagnetic signals at a particular wavelength; a receiver unit disposed on the receiver region and configured to respond to electromagnetic signals emitted by the emitter unit; a transparent molding unit disposed on the emitter region and the receiver region of the substrate panel; and an optical shielding layer selectively disposed on the external surfaces of the substrate panel and the transparent molding unit. The shielding layer has corresponding sensor ports for the emitter and the receiver units arranged toward a designated detection region. The electro-less plated optical shielding layer is highly configurable through proper masking and small in thickness, enabling further miniaturization of the sensor unit.
