A lighting system for improving the alertness of a person comprising: one or more light sources (101) arranged to emit light into an environment, at least one of the one or more light sources being arranged with a primary function comprising providing illumination into the environment; and a controller (103) configured to cause at least one of the at least one light sources to provide a secondary function of emitting at least a first light pulse (503) having a duration of between 1 ms and 50 ms, wherein there is an idle period (505) lasting at least 0.1 s on either side of the first light pulse.

An automatic driving system includes: an interior light configured to illuminate a vehicle compartment of a vehicle; an interior light control unit configured to control the interior light; and a driving control unit configured to perform automatic driving control of automatically driving the vehicle, end the automatic driving control when the automatic driving control is being performed, and switch driving of the vehicle from automatic driving to manual driving. The interior light control unit is configured to perform, when the interior light is lighted while the automatic driving control is being performed, dimming control of decreasing an illuminance of the interior light before the driving control unit switches the driving of the vehicle from the automatic driving to the manual driving.

A projection type display device includes: a first light source that emits visible light; a projection receiving member which is disposed on a windshield of a vehicle, to which an image based on the visible light is projected; a second light source that emits ultraviolet light which decreases a light transmittance of the projection receiving member by irradiation of the projection receiving member; a projection unit that projects the visible light emitted from the first light source and the ultraviolet light emitted from the second light source to the projection receiving member; an imaging unit that performs imaging of a scene at front of the windshield of the vehicle; and a detection unit that detects an object image having brightness greater than or equal to a first threshold as defined herein, and the projection unit projects the ultraviolet light as defined herein.

A vehicular cabin monitoring system includes a camera disposed within a cabin of a vehicle. Image data captured by the camera is transferred to and is processed at an electronic control unit (ECU). A light emitter that, when electrically operated to emit nonvisible light, illuminates at least a portion of the interior cabin that is viewed by the camera with nonvisible light. The vehicular cabin monitoring system, via processing at the ECU of image data captured by the camera and transferred to the ECU, determines illuminance of nonvisible light at a region of interest within the illuminated portion of the interior cabin that is viewed by the camera. The vehicular cabin monitoring system, responsive to determining that the illuminance of nonvisible light at the region of interest is greater than a threshold illuminance, reduces intensity of nonvisible light emitted by the light emitter.

The invention relates to a shaped part comprising a decorative layer with a front side and a rear side, a light-guiding element comprising a main body and one or more light guides protruding from a front side of the main body, wherein the main body is arranged with its front side on the rear side of the decorative layer and the light guide(s) completely penetrate/s the decorative layer, and one or more light elements arranged in and/or on the light-guiding element, wherein light emanating from the light elements is guided via the light guide(s) to the front side of the decorative layer. A light-shielding layer is arranged between the surface of the light guide(s) and the decorative layer, in particular a light-shielding element, wherein the light-shielding layer has an interruption, through which light can escape, on the front side of the decorative layer on each light guide. The invention also relates to methods for producing a shaped part that comprise, as a method step, pressing the light-shielding element and/or the light guides of the light-guiding element into a decorative material to form the decorative layer.
