The present invention relates to a lighting system including a primary light source producing a primary light beam in the direction of a conversion device that returns a secondary light radiation to an optical imaging system forming a projected light beam. A light sensor generates a signal corresponding to the light received by this sensor. The light includes a non-converted light part of the first primary light beam which is returned by the conversion device in the projected light beam and is reflected by an obstacle situated in the zone illustrated by said projected light beam. A control unit has modulation means generating a modulation signal for the primary light, and demodulation means for processing the signal formed by said sensor, and determines a distance between the obstacle and the lighting system.

A vehicle applique is provided that includes a substantially transparent substrate defining first and second surfaces, a decorative film positioned on the first surface of the substrate, and an over-mold positioned over the film. The over-mold defines at least one diffraction grating and a light source is positioned proximate the second surface of the substrate. The light source is configured to emit light through the substrate and the over-mold.

A lamp assembly is provided herein. The lamp assembly includes first and second light sources disposed in a housing. The first and second light sources emit light at varied wavelengths. A badge is disposed on a vehicle and is operably coupled with the first light source. A photoluminescent structure is disposed on the badge and is configured to luminesce in response to receiving an excitation light emitted by the first light source.

A lamp for an automobile and the automobile. A lamp for an automobile includes: a substrate part; a plurality of light sources provided in close contact with a top surface of the substrate part and configured to emit light; a fluorescent layer spaced upward from the substrate part and the plurality of light sources and including a fluorescent material; and an inner lens provided in close contact with a top surface or a bottom surface of the fluorescent layer.

A vehicle notification system is disclosed. The system comprises a light generating layer conforming to a surface of a decklid configured to enclose a storage compartment. The light generating layer comprises a plurality of LEDs in a semiconductor ink operable to emit a first emission. The system further comprises a controller configured to selectively activate the plurality of LEDs in response to a first signal from a decklid ajar indicator and a second signal from an emergency lighting module.

A vehicle is provided herein. The vehicle includes a panel having a light-producing assembly including a plurality of light sources arranged therein and attached to the panel. A photoluminescent structure is disposed on the light-producing assembly and is configured to luminesce in response to excitation by the plurality of light sources. A vehicle sensor is configured to initiate an illumination sequence of the plurality of light sources based on a change in vehicular movement. A controller for illuminates the plurality of light sources based on predefined events when an electronic device is disposed proximately to the vehicle and is in communication with the controller.

An illumination device includes a light source and a light guide including a first light guide portion and a second light guide portion. The second light guide portion contains a light-emitting face, and the excitation light emitted by the light source is coupled and enters the first light guide portion and is emitted via the light-emitting face of the second light guide portion. The area of the cross section, perpendicular to a light guide central line, of the second light guide portion is gradually decreased in the direction of an optical axis of the light source. An angle between an intersecting line of the light-emitting face of the second light guide portion and the cross section passing through the light guide central line or any tangent line of the intersecting line and the light guide central line is an acute angle.
