  • Publication number: 20240159977
    Abstract: A surface mountable optoelectronic device with side walls including slots filled with a laminated encapsulant material is presented herein. A surface mount technology (SMT) optoelectronic device includes a substrate, a housing, at least one optoelectronic chip, and an encapsulant material. The substrate includes electrical terminals that facilitate attachment and electrical coupling of the SMT optoelectronic device to a printed circuit board. The housing includes an opaque material and a cavity, in which the substrate is positioned at a bottom portion of the cavity, and a top portion of the housing includes a group of slot openings. The at least one optoelectronic chip is electrically connected to the electrical terminals, and is mounted, within the cavity, to the substrate. The encapsulant material is translucent or transparent, and has been included in the cavity and the slot openings.

  • Patent number: 11978838
    Abstract: A surface mountable light emitting diode (LED) package with inclined light emitting surface is presented herein. An optoelectronic component comprises the surface mountable package, which comprises a top surface, a cavity, and a mounting surface that is parallel to the top surface to facilitate an attachment, via an automatic surface mount technology pick-and-place equipment, of the mounting surface to a printed circuit board of the optoelectronic component. The cavity comprises a material that facilitates a transmission of electromagnetic radiation comprising visible light and infrared light, optoelectronic device(s) positioned within the cavity that generate and/or receive the electromagnetic radiation, and a light emitting surface that is adjacent to the top surface and that is inclined at an angle relative to a vertical axis of a plane of the top surface to facilitate, via the material, a transmission/reception of the electromagnetic radiation from/by the optoelectronic device(s).
