A slide device includes an upper rail to which a slide seat for a vehicle is attached, a slide rail to which the upper rail is slidably attached, a light emitter, and an attachment portion that attaches the light emitter to the upper rail. The attachment portion is attached to the upper rail such that the light emitter is arranged outside the slide rail. According to the slide device, since the attachment portion is attached to the upper rail such that the light emitter is positioned outside the slide rail, the light emitter does not move inside the slide rail to which a large amount of grease is applied, and a decrease in communication performance can be prevented.

To more appropriately adjust the brightness inside a vehicle. Provided is a system including: a first vehicle configured to output, to a server, information regarding illuminance of light incident on a vehicle by associating with information regarding a traveling environment; a second vehicle configured to output information regarding a traveling environment to the server; and the server including a controller configured to generate, based on the information regarding the illuminance of the light incident on the first vehicle, information regarding a sudden-change point that is a point at which a change amount of the illuminance of the light incident on the first vehicle exceeds a prescribed value, and configured to output, based on the information regarding the traveling environment of the second vehicle acquired from the second vehicle, information regarding the sudden-change point to the second vehicle.

A light module (100, 400, 600, 900, 1600) for a lighting device of a vehicle comprises a light source part and an outer housing (101) enclosing the light source part and having at least a first surface (103) and a second surface (104). The first surface of the outer housing comprises a first interlock shape (201, 202, 1001) and the second surface comprises a second interlock shape (201, 202, 901) arranged to be at least mechanically compatible with the first interlock shape. Two similar light modules are at least mechanically connectable to each other by connecting the first interlock shape of one of the light modules to the second interlock shape of the other light module. At least one of said first and second interlock shapes is continuous in a first direction (105, 905) and periodic in a second direction (106, 906). The first and the second direction are directions parallel to the surface on which the interlock shape is arranged.

A lighting device includes a light guide that propagates incoming light, and a lighting panel including a lighting region. A front side of the lighting panel excluding the lighting region is configured to prevent transmission of light, the light guide is covered by the lighting panel, the lighting device is configured such that the light emitted from the light guide passes through the lighting region of the lighting panel for illumination, and surfaces of the lighting panel surrounding the light guide are white in color.

A vehicular display device according to an embodiment includes a light shielding housing fixed to a surface of a roof of a vehicle on a cabin side and having a concave portion concave upward, an opening portion formed at a position facing a rear of the vehicle in the concave portion, and a display device having a display surface disposed in the opening portion with the display surface directed to the rear of the vehicle.

A trim component, such as a grill of a vehicle, includes a substrate having a 3-dimensional shape and defining a disrupted reflective surface including a plurality of facets over a curved surface. Each of the facets is configured to reflect an incident light beam in a common direction, for example, toward a given target. A reflective coating, such as a chrome plating layer, overlies the disrupted reflective surface. The facets may have similar shapes and/or be arranged in a repeating pattern, but with one or more irregular features. The sizes, shapes, and/or orientation direction of the facets may varying in a gradient based on the curvature of the curved surface. The trim component also includes a light source to illuminate the disrupted reflective surface. The light source may be hidden so it is not directly visible to a viewer, but instead is reflected by the disrupted reflective surface.

An optical conductor has several spherically curved light-extraction areas on its surface that are arranged in spaced relationship to one another and have a particular height (h) and a particular radius (R) of surface curvature, wherein h/R ratios of the respective height to the respective radius of all light-extraction areas are substantially equal and lie within a range of 0.1 to 0.45. A lighting system comprises one or more optical conductors and one or more light sources for irradiation of at least one light-injection area of the optical conductor, wherein useful light radiated from the front of the optical conductor can be emitted unscattered from the lighting system and/or interference light emitted outside of a useful light path is absorbable by the lighting system. Some embodiments may be particularly applicable in vehicle lighting systems.
