A vehicle is provided herein. The vehicle includes a headliner including a cover. A first luminescent structure is disposed on the cover and is configured to luminesce in response to excitation by a light assembly. The light assembly is disposed below the headliner. A controller is configured to activate the light assembly. The light assembly independently illuminates various portions of the luminescent structure.

A climate status indicator for a vehicle includes a light guide positioned around a vent perimeter. The climate status indicator additionally includes a light device coupled to at least one vent fin. The light guide and/or the light device are configured to provide a visual indicator of a climate status.

The invention concerns a device for lighting the passenger compartment of a motor vehicle. The device includes a variable light-emitting element adapted to generate selectively a light beam having at least one variable characteristic, and a device for measuring the ambient temperature in the passenger compartment of the vehicle. A device for controlling the variable light-emitting element is configured to control the emission of the light beam and to vary the variable characteristic of the light-emitting element as a function of the ambient temperature measured by the device for measuring.

A public transport land vehicle, in particular of the bus type, includes a passenger compartment intended to accommodate several people, and at least one technical compartment which can be accessed from the passenger compartment, at least one technical compartment, called upper compartment, is arranged on/in the upper wall of the passenger compartment.

An air vent with an adjustment insert for adjusting an air stream flowing out through the air vent, can be adjusted by rotating the adjustment insert. A first light guide and a second light guide are provided, with the first light guide being firmly attached to a housing of the air vent and the second light guide being firmly attached to the adjustment insert. The first light guide and the second light guide are rotatable with respect to each other, and the second light guide can be illuminated by the first light guide. A backlightable portion of the adjustment insert can be illuminated by the second light guide.

A method for illuminating a passenger compartment of a vehicle with lighting devices which each contain one or more diffuse and/or indirect light sources. The intensity and color of the light emitted by the light sources being set automatically as a function of specific operating parameters which are influenced by a vehicle occupant. The lighting devices which are respectively spatially assigned to an area of the passenger compartment of the vehicle in which there is a vehicle component with an operating parameter which can be set separately by the driver and which can act on a general operating mode selected by the driver, are actuated in such a way that their intensity and color indicate to the driver whether the current setting of the separately settable operating parameter has a positive or negative effect on the general operating mode selected by the driver.

A multifunctional lamp for a vehicle interior includes a housing having a light source installed therein. An indirect illumination diffusing lens is disposed in front of the housing to diffuse and emit light of the light source. A concentrated illumination light emitting unit moves back and forth while passing through the light diffusing lens. The concentrated illumination light emitting unit emits the light of the light source toward a front side of the housing through an internal passage of the light emitting unit in the form of concentrated illumination and shields the light diffusing lens from the light when concentrated illumination light emitting unit moves to surround a periphery of the light source.

An air vent device for a vehicle includes an air guide configured to protrude towards a passage through which air flows, wherein a length of the air guide protruding into the passage is adjustable by rotation with respect to the passage.

The purpose of the present invention is to provide a light guide plate with which it is possible to prevent light unevenness and improve appearance, and a light emitting device using the same. A light guide plate (11) is provided with: a light incidence surface (12) on which light is incident; a light emission surface (13) which faces the light incidence surface (12) and from which light incident from the light incidence surface (12) is emitted; and a flat plate-shaped light guide member (14) which guides the light incident from the light incidence surface (12) to the light emission surface (13). The light guide member (14) has a widened portion (16) that is widened outward in a plate width direction from the light incidence surface (12) toward the light emission surface (13), and in a cross-section parallel to the light emission surface (13) on the light emission surface (13) side of the light guide member (14), the light guide member (14) has a larger plate thickness at least on one end side in the plate width direction on the side farther from the light incidence surface (12) than the plate thicknesses of the other portions.
