Abstract: A lamp assembly for a vehicle configured to display a logo or other indicia in the form of a virtual image indicium. The lamp assembly includes a dark chamber having a mirror image indicium with an indicium light source associated with the dark chamber, and a light chamber having an associated primary light source. A transparent divider is configured to reflect the mirror image indicium when the indicium light source is illuminated to create the virtual image indicium that is perceivable by an observer.

Abstract: A light ring assembly that is designed to provide bright, uniform and homogenized illumination and that can be used with any number of vehicle and non-vehicle lighting applications. According to one embodiment, the light ring assembly includes a housing, a circuit board with a number of individual light sources, a light ring and a lens. Light emitted by the light sources enters an optical input surface on a bottom side of the light ring, is reflected within the body of the light ring so as to mix and become more distributed, and then exits an optical output surface on a top side of the light ring.

Abstract: An automotive light guide that displays subsurface engraved indicia to create an optical branding feature or another illuminated design element. In one implementation, the light guide has a body with a primary viewing outer side and a plurality of microablation sites located within the body. From a first viewing angle with respect to the primary viewing outer side, the plurality of microablation sites are configured to appear in a first indicia pattern, and from a second viewing angle, the plurality of microablation sites are configured to appear in a second indicia pattern. In another implementation, the light guide has a body with a planar engraving outer side and a rounded primary viewing outer side. The plurality of microablation sites are etched through the planar engraving side and are viewable as an indicia pattern through the rounded primary viewing outer side.

Abstract: An illumination device, such as the type used for vehicle exterior applications, includes a housing with light collimating and spreading portions, a circuit card assembly with one or more light sources (e.g., LEDs), and a lens. The illumination device may be arranged so that light emitted by the LEDs reflects off of a metalized interior surface of the light collimating portion in a collimated fashion and travels towards the light spreading portion, the collimated light then reflects off of a metalized interior surface of the light spreading portion in a spread fashion and travels towards the lens, and the spread light passes through the lens and travels towards an intended target region. The illumination device may be installed, for example, in a rear hatch of a vehicle and used in conjunction with a backup camera.

Abstract: Multi-color illumination devices that can be used in various indicator-related or ambient lighting applications, particularly for vehicles. In accordance with one embodiment, the multi-color illumination device includes a light guide having a first end and a second end, a first light source located adjacent the first end of the light guide, and a second light source located adjacent the second end of the light guide. The multi-color illumination device is configured for attachment to a controller configured to illuminate the first light source, the second light source, or both the first light source and the second light source in accordance with one or more operation parameters to provide a status indication.

Abstract: A light assembly that acts as a light source multiplier. The light assembly includes a light guide having a light source side and an emitting side with a center portion between the light source side and the emitting side. Both the light source side and the emitting side have a truncated sawtooth shape. The light source side has a plurality of truncated portions and a plurality of apex portions between each truncated portion, with one or more of the apex portions ending in the center portion of the light guide. In some implementations, a number of light guide segments are oriented in a lattice configuration.

Abstract: A color mixing illumination device and method of using the same. The color mixing illumination device includes a printed circuit board (PCB) having a PCB surface with a reflective portion; a multi-color light source attached to the PCB, such as a red-green-blue light emitting diode (RGB LED); and a reflector with a reflector surface. The PCB surface and the reflector surface are configured to mix light from the multi-color light source in a mixing region and then direct mixed light out of the device from an exit region. In one embodiment, the color mixing illumination device is a multi-color indicator lamp for a vehicle.

Abstract: An illumination device that includes an elongated light pipe and attachment wings integrally formed on the sides of the light pipe so that the illumination device can be easily, yet securely, installed within a containment channel, such as those found on the underside of a vehicle step rail. The elongated light pipe is made of an optically transmissive material, the attachment wings are made of a different resilient material, and the overall device is a single extruded component that has a co-extrusion boundary separating the two materials. The illumination device illuminates the ground, for example, when passengers are entering or exiting the vehicle.

Abstract: An illumination assembly for a vehicle. The assembly includes a lamp having a first light source; a first collimator adapted to receive light from the first light source; and an optical wedge, wherein the first collimator is positioned between the first light source and the optical wedge.

Abstract: An illumination assembly for a vehicle that includes a housing, a light source, and an illumination device with an optical body. The optical body includes: a first major surface; a second major surface; an edge surface; a first reflective feature that includes a recess with side walls; and a second reflective feature that includes a curved reflector. The light source is mounted adjacent the first major surface so as to oppose the first reflective feature. In operation, light emitted from the light source enters the optical body at the first major surface, reflects off of the first and second reflective features, and exits the optical body at the edge surface so as to illuminate an area of interest behind the vehicle.

Abstract: An illumination device for a vehicle. The illumination device may be used to selectively illuminate a truck bed or another vehicle location or compartment. The illumination device includes a primary lens having a plurality of optical features that help target light in preferred directions. The optical features may include optical segments or optical portions having a number of optical wedges. In one embodiment, the illumination device is used in a truck bed application.

Abstract: A waveguide for controlled light distribution is described. The waveguide may include a body that longitudinally extends from a proximate end to a distal end. And the body may include a plurality of scattering flanges axially extending toward the proximate end on a first longitudinal side and a plurality of notches interposed between each of the plurality of scattering flanges.

Abstract: A clip unit and an edge mount light emitting diode (LED) assembly comprising a clip unit. The clip unit provides a mounting structure for mounting a light source, such as an LED, to an edge of a printed circuit board (PCB). A surface mount LED, for example, can thus be easily mounted to the edge of the PCB so as to project light in a direction normal to the edge surface of the PCB, instead of the typical mounting orientation that allows for the projection of light normal to the primary surface of the PCB. The clip unit includes an anode retention clip and a cathode retention clip which are electrically isolated from one another within an insulative housing portion.
