  • Patent number: 10622522
    Abstract: Emitter packages are disclosed that can include an insulating layer covering the emitter, such as between the emitter's primary emission surface and a lens or encapsulant. The packages can comprise a submount with an emitter flip-chip mounted such that the diode region is between the emitter's non-insulating and/or conductive substrate and the submount. The submount can then be covered with a thin insulating layer. The same or another insulating layer can cover other electrically active surfaces on the submount. By insulating the electrically active surfaces of the emitter and, in some embodiments, other electrically active surfaces, the package can meet UL8750 class 4 enclosure standards even if it does not meet the lens adhesion criteria. This can enable the use of cheaper and/or more optically efficient materials at the fixture level, since the package itself meets class 4 standards.
