Abstract: A light-emitting assembly configured to generate varied color light includes an assembly housing. The light-emitting assembly also includes a light filter element fixed relative to the assembly housing. The light filter element includes a plurality of transparent nanostructured ElectroChromic (TNEC) layers. When at least one of the plurality of TNEC layers is subjected to voltage, the subject TNEC layer(s) imparts a distinct reflective color to ambient light entering the light-emitting assembly. Such a light-emitting assembly may be specifically adapted for use on a motor vehicle.

Abstract: A light-emitting assembly includes an outer lens. The outer lens has a lens exterior surface and a lens interior surface. The outer lens also defines a window between the lens exterior surface and the lens interior surface. The light-emitting assembly additionally includes a light element fixed to the outer lens in the window. The light element is exposed on the lens exterior surface, and configured to direct a beam of light away from the outer lens exterior surface. Such a light-emitting assembly may be specifically adapted for use on a motor vehicle.

Abstract: A light bar for an exterior lighting assembly of an automotive vehicle includes a body portion and an ornamental element. The body portion is made of a substantially transparent material and has a generally slab-like shape with an average height H in a z-direction, an average width W in a y-direction and an average thickness T in an x-direction, wherein the x-, y- and z-directions are mutually orthogonal and H>W>T. The ornamental element is disposed within the body portion and has an outer surface, wherein at least a portion of the outer surface contains a light-scattering material.

Abstract: An automotive vehicle includes a body, a housing disposed on the body, and an exterior lens coupled to the housing defining a cavity therebetween. The vehicle additionally includes an interior lens disposed in the cavity. The exterior and interior lenses have distinct first and second colors, respectively. The vehicle also includes a reflector disposed in the cavity. The reflector has an at least partially reflective coating disposed thereon and is positioned to reflect light from the interior lens and to the exterior lens. The vehicle further includes first and second light sources configured to emit light having a third color. The first light source is oriented to direct light through the exterior lens without passing through the interior lens, and the second light source is oriented to direct light through the interior lens, reflect from the reflector, and subsequently through the exterior lens.
