  • Patent number: 10766175
    Abstract: The invention relates to a method for producing a trim element for vehicles which has a genuine carbon appearance, comprising a carbon fiber layer which is arranged on an exposed side of the trim element and is visible from the outside, and which is made of a fiber structure composed of prefabricated carbon fibers with interstices, with the method comprising at least the process step of wet impregnating the prefabricated carbon fiber layer with an aqueous polymer dispersion based on polyurethane, acrylate or polyvinyl acetate or a mixture thereof, so that the polymer dispersion penetrates at least partially into the carbon fiber layer, increasing the suitability thereof for penetration of a coating into the interstices of the fiber structure of the carbon layer.

  • Patent number: 10676451
    Abstract: Disclosed is a process for purifying propylene oxide. A stream S0 containing propylene oxide, acetonitrile, water, and an organic compound containing one or more of acetone and propionaldehyde is provided. Propylene oxide is separated from S0 by subjecting S0 to distillation in a first distillation unit, obtaining a gaseous top stream S1c enriched in propylene oxide, a liquid bottom stream S1a enriched in acetonitrile and water, and a side stream S1b containing propylene oxide and enriched in the carbonyl compound; reacting the carbonyl compound in S1b with an organic compound containing an amino group to obtain a reaction product; separating propylene oxide from the reaction product in a second distillation unit, obtaining a gaseous top stream S3a enriched in propylene oxide and a liquid bottoms stream S3b enriched in the reaction product; and introducing stream S3a into the first distillation unit.

  • Patent number: 10665762
    Abstract: LED lamps or bulbs are disclosed that comprise a light source, a heat sink structure and a remote phosphor carrier having at least one conversion material. The phosphor carrier can be remote to the light sources and mounted to the heat sink. The phosphor carrier can have a three-dimensional shape and comprise a thermally conductive transparent material and a phosphor layer, with an LED based light source mounted to the heat sink such that light passes through the phosphor carrier. The phosphor carrier converts at least some of the LED light, with some embodiments emitting a white light combination of LED and phosphor light. The phosphors in the phosphor carriers can operate at a lower temperature to have greater phosphor conversion efficiency and reduced heat related damage. The lamps or bulbs can also comprise a diffuser over the phosphor carrier to distribute light and conceal the phosphor carrier.

  • 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.

  • Patent number: 10359151
    Abstract: Lamps and bulbs are disclosed generally comprising different combinations and arrangements of a light source, one or more wavelength conversion materials, regions or layers which are positioned separately or remotely with respect to the light source, and a separate diffusing layer. This arrangement allows for the fabrication of lamps and bulbs that are efficient, reliable and cost effective and can provide an essentially omni-directional emission pattern, even with a light source comprised of a co-planar arrangement of LEDs. The lamps according to the present invention can also comprise thermal management features that provide for efficient dissipation of heat from the LEDs, which in turn allows the LEDs to operate at lower temperatures. The lamps can also comprise optical elements to help change the emission pattern from the generally directional (e.g. Lambertian) pattern of the LEDs to a more omni-directional pattern.
