  • Patent number: 11870013
    Abstract: An optoelectronic module is provided that has a carrier element, an optoelectronic element on the carrier element, a cover, and a cavity. The cover has a frame surrounding the optoelectronic element and connected to the carrier element. A glass element is on the frame lying substantially opposite the carrier element for the input and/or output of electromagnetic radiation. The cavity is inside a volume that is delimited by an inner surface of the cover and a surface of the carrier element. The optoelectronic element is arranged in the cavity and enclosed by the cover hermetically and/or in an autoclavable fashion. A filler material is in the cavity to compensate for an expansion of a volume occupied by the filler material and has a first deformable compensation volume, which is arranged adjacent to a subregion of the cover and/or of the carrier element.

  • Publication number: 20210230041
    Abstract: A method is provided for producing a patterned glass wafer for packaging electronic devices in a wafer assembly. The method includes placing a glass sheet between two mold halves and heating until the glass sheet softens, while the mold halves are pressed against one another so that the glass sheet is reshaped and forms a patterned glass wafer. The first mold half has an array of projections and the second mold half has an array of recesses. The mold halves are arranged and shaped so that the recesses and projections oppose each other. The projections introduce cavities into the glass sheet during the reshaping and with the glass flowing into the recesses of the second mold half during the reshaping. The recesses are deep enough for the glass to at least partially not come in contact therewith and to form a convexly shaped glass surface in each recess.

  • Patent number: 10900651
    Abstract: A method and device for aligning a light spot of light exiting from at least one light guide on an optical converter are provided. The device includes a light guide from which light exits and is incident on an optical converter to at least a substantial fraction, thereby forming a light spot thereon, wherein the exit surface of the fiber has an angle relative to the longitudinal axis of the fiber which is different from 0°, and the position of the light spot on the converter is aligned by adjusting the angle. A conversion module as a part of a lighting device is also provided that is operated with excitation light of a light source using a fiber-optical light guide.
