  • Light source, method of manufacturing the light source, and method of mounting the light source
    Patent number: 10833235
    Abstract: A light source includes a light emitting element configured to emit a light; a mounting substrate; and a ceramic substrate having a light emitting element mounted thereon and being bonded to the mounting substrate via a plurality of metal bumps made of gold, copper, a gold alloy, or a copper alloy. A method of manufacturing a light source includes forming a plurality of metal bumps on a mounting substrate; providing a ceramic substrate having at least one light emitting element mounted thereon; and bonding the mounting substrate and a ceramic substrate to each other via the metal bumps.
    Type: Grant
    Filed: November 3, 2016
    Date of Patent: November 10, 2020
    Assignee: NICHIA CORPORATION
    Inventor: Takuji Hosotani
