A two-dimensional light guide has at least three layers, including two layers formed as films have a lower refractive index than a light guidance layer arranged between them. One of the films has decoupling structures for the light. The layers form a film composite in which the light guidance layer is formed as a film. A lighting element can include having such a two-dimensional light guide and a coupled input coupling light guide. A trim part can have a light source coupled with the two-dimensional light guide and include lighting and the input coupling light guide is arranged such that a surface portion is actively lit and a non-light-transmissive surface portion hides the light source and the coupling when viewed from a viewing direction.

An arrangement for irradiating a surface includes a radiation source configured to emit ultraviolet radiation, a reflector for directional radiation of the ultraviolet radiation onto the surface, and a control device. A dose of the ultraviolet radiation required for sterilizing the surface and/or a dose already administered is settable and/or determinable by the control device.

Arrangement for irradiating a surface

A method for controlling a lighting system in an interior chamber of a vehicle having controllable light sources that generate at least one reading light with a defined light cone and a light spot is provided. A gesture camera recognizes gestures of a person located in the interior chamber and the lighting system is controlled by the recognized gestures. A light controller is active between a starting point in time and an end point in time. When the light controller is active and in the event of a gripping or pointing gesture of a hand in the region of the light cone or light spot, the light cone or light spot is guided along with the hand carrying out the gesture.

Method for controlling a lighting system so that a light follows movement of a hand

An illumination unit for an interior chamber of a vehicle includes at least one light source integrated into a surface side of a sun shield facing towards an occupant in a non-usage position of the sun shield. The at least one light source emits light in the activated state which is directed towards the occupant. A covering element is provided for covering a light outlet surface of the light source.

Illumination unit and vehicle

A device for controlling ambient lighting of a vehicle includes a light element in a vehicle interior, a touch-sensitive display unit, and a control unit. The light element emits light in one of a plurality of colors that can be generated by the light element. The display unit displays a plurality of colors of a predefined color spectrum simultaneously in a color scale, and detects a location of a user input made by touching the display unit. Via the detected location, the user input is assigned to an associated color displayed in the color scale and information about the color assigned to the user input is transmitted to the control unit, which controls the light element for emitting light in the color assigned to the user input. The light element and display unit have the same color space, such that the color associated with the user input, displayed on the display unit are the same.

Color selection for ambient lighting of a vehicle

A device for controlling an interior lighting system of a vehicle to produce ambient lighting and/or reading lighting involves the interior lighting system having an array of a plurality of light sources. The device includes a control unit, by means of which the light sources of the array can be individually controlled in order to produce the ambient lighting and/or the reading lighting, and an input unit that can be connected to the control unit. The input unit has a touch-sensitive screen for inputting a current set of control information for the control unit. The control unit controls the light sources on the basis of the current set of control information. Furthermore, the input unit, on the basis of the current set of control information, displays associated ambient lighting and/or reading lighting for an illuminable region in the vehicle interior on the screen.

Device and method for controlling an interior lighting system of a vehicle

A method for feedback of a temperature setting of an air-conditioning device involves adjusting a light color of at least one lighting element for the display of a set temperature. The adjusted light color corresponds to a temperature setting of an airflow zone in a motor vehicle.

Method for feedback of a temperature setting

A communication network for networking lighting systems of home and office technology involves an application on a mobile terminal that can control lighting systems in the surroundings of the mobile terminal. The lighting systems in the interior of a vehicle are also networked and the lighting systems are controlled depending on the lighting settings of a screen of the mobile terminal.

Control of lighting systems

An illuminated decorative part includes a flat visible side facing an observer and an illumination region behind the visible side as viewed by the observer, which has multiple discrete light sources. At least partially transparent optical elements that influence the light are arranged between the visible side and the illumination region. The optical elements include at least one flat scattering element. The decorative part includes light guides for guiding the light orthogonally to the surface of the visible side arranged between the scattering element and at least one&#x2014;but not all&#x2014;of the light sources.

Illuminated decorative part

A device for interior illumination for a vehicle includes an array formed by multiple light sources, with which an ambient illumination and a reading illumination can be generated inside the vehicle, an additional lamp unit with which exclusively an ambient illumination can be generated inside the vehicle, and a control unit for controlling the light sources and the additional lamp unit in three modes. The control unit is designed and configured in such a way that in the first mode the light sources are controlled in such a way that exclusively a reading illumination is generated inside the vehicle; in the second mode the light sources and the additional lamp unit are controlled in such a way that exclusively an ambient illumination is generated inside the vehicle; and in the third mode the control unit simultaneously activates the first and second modes for simultaneously generating an ambient illumination and a reading illumination.

Device and method for interior illumination for a vehicle

A motor vehicle trim part with illumination includes a visible panel that is at least partly translucent and has a visible side. At least one illuminating element is arranged on the opposite side of the visible side of the visible panel. At least one light guide is arranged so that the light of the at least one illuminating element can be coupled and which is optically coupled to the visible panel. The at least one light guide defines a first light path, the end face of which is optically coupled to the visible panel, and a second light path is defined, the lateral surface of which is coupled to the visible panel.
