  • Publication number: 20160201874
    Abstract: An ornamental device including a decorative plated surface and a backlit assembly is described, and includes a light engine including a light-emitting diode (LED), a light pipe optically coupled to the LED, a light diffuser and a lens assembly. The lens assembly includes a chrome surface finish, wherein the lens assembly encases the light engine, the light pipe and the light diffuser, and is assembled onto a back plate. When the LED is not illuminated, the lens assembly exhibits a chrome appearance, and when the LED is illuminated, light emanates through the lens assembly.

  • Publication number: 20150124098
    Abstract: A vehicular camera includes a lens, a printed circuit board and an imager. The lens has a plurality of optical element and is disposed at a lens holder. The imager is disposed at the printed circuit board. The adhesive is initially curable in an initial radiation curing process that comprises exposure to UV light, and initially-cured adhesive is further curable to a further cured strength in a secondary thermal curing process. The adhesive is initially cured via the initial radiation curing process after the lens is brought into focus with the imager and is optically center-aligned therewith. The initially-cured adhesive, as cured via the initial radiation curing process, holds the lens optically center-aligned and in focus with the imager. After the initial radiation curing process, the lens holder, adhesively attached to one of the printed circuit board and the holding element, is moved to the secondary thermal curing process.
