  • Patent number: 7368758
    Abstract: A method is provided for producing a housing body for optoelectronic components that are reliable and inexpensive. The method creates a hermetic joint between a metal sleeve and a glass pane by joining together a housing element and a preferably metallic housing arrangement. The housing element and the housing arrangement are brought into contact with a glass solder, before the housing element and housing arrangement are joined. The glass solder is applied as a shapeable material, in particular as a paste. The glass solder is pre-vitrified and has its shape fixed by energy being introduced at least once, in particular as a result of organic constituents being burnt off. After the housing element has been inserted into the housing arrangement, a joint that is hermetic at least in regions, is produced between the glass pane and housing arrangement.

  • Publication number: 20050224827
    Abstract: The invention relates to a method for producing a housing body at least parts of a housing body, especially for encapsulating optoelectronic components. According to the inventive method, a housing element is joined to a preferably metallic housing structure, and the housing element and the housing structure are brought into contact by means of a glass solder. The aim of the invention is to enable a reliable, cost-effective and preferably hermetic join to be created between the metallic sleeve and the sheet of glass. To this end, the glass solder is applied as a mouldable mass, especially as a paste, before the housing element and housing structure are joined; the glass solder is pre-vitrified and fixed in its shape by means of at least one single energy input, especially by burning out organic constituents; and once the housing element has been inserted into the housing structure, an at least partially hermetic join is created between the sheet of glass and the housing structure by means of heating.
