Definitions

  • the invention relates to a cladding element for at least partially covering a wall or a ceiling and an illumination system for illuminating a room with at least one workstation and preferably several workstations.
  • lamps are used in different adapted to the particular application embodiments.
  • the aim is mostly to produce with the lights light distribution curves that allow the best possible illumination for a particular situation.
  • standing or floor lamps are often used in offices for illuminating workstations such as desks.
  • luminaires can in part provide good illumination of individual workstations, they can impair the use of the room and are often perceived as disturbing.
  • such lights must be set up for optimum illumination of a workplace typically close to this, which is often undesirable and impractical, especially in regularly changing jobs.
  • ceiling lights are also used, from which the workplaces are illuminated.
  • Area lights can be comparatively small and focused or designed to be larger and wider.
  • ceiling lights can be preferably illuminated by means of such ceiling lights and although such lights are relatively less disturbing, since they are not placed in places where things are placed or persons are, they are relatively inflexible. Particularly in the case of regularly changing workplaces, for example in offices in which, for example, workstation groups are formed depending on the project, such ceiling lights are usually too inflexible since they have to be relocated, reoriented and configured. Also for the interior design such ceiling lights are often undesirable because they are typically fixed and therefore can not be redesigned.
  • the object of the invention below is therefore to propose a system which enables a flexibly adaptable and configurable, specific illumination of workplaces in a room.
  • a cladding element for at least partially covering a ceiling or a wall of a room comprises a planar carrier substrate having a front side and a rear side, a fastening structure arranged on the rear side of the carrier substrate and a light shaping structure arranged on the front side of the carrier substrate.
  • the attachment structure is designed for fastening the cladding element to a wall or a ceiling.
  • the light-shaping structure is designed to reflect a light beam directed onto the cladding element and to generate predefined light properties in the reflected light.
  • ceiling can refer in the context of the invention to an upper boundary of an open or closed space. Not mandatory but typically Ceilings aligned horizontally.
  • wall in the same context may refer to a lateral boundary of the open or closed space. Walls are typically vertical or substantially vertically aligned. The ceiling and the wall may be formed by plastered masonry, panels, stretched textile materials, metals, concrete, glass, stone materials or the like.
  • the term "for covering" in connection with the cladding element can be understood to be arranged on the ceiling or wall, so that the ceiling or wall at the location where the cladding element is positioned is not or at least not completely visible from the room.
  • the cladding element may lie directly against the ceiling or wall or it may be spaced therefrom.
  • predefined light properties or “predefined luminous properties” in connection with the reflected light may refer to the properties of a luminous flux directed onto the cladding element and the nature of the light-form structure which define the luminous properties specifically for illuminating a room or a workstation ,
  • the light properties of the reflected light can be predefined in such a way that a light distribution curve (LVK) specifically provided for the workstation or space involved is achieved.
  • a workstation can advantageously be specifically illuminated and / or an adapted advantageous basic lighting can be generated in the room.
  • different light atmospheres such as, for example, diffused and / or directed are created.
  • predefined in this sense are luminous properties which are present without being adapted or included in determining the illumination of the room or the workplace.
  • the term "light distribution curve” is understood to mean a characterization of the light emitted by a luminaire, which can be represented in a graph.
  • the light intensities are connected in their different directions of radiation with each other to form a curve.
  • the light distribution describes the spatial distribution of the light.
  • Shape and symmetry of Light distribution characterize a depth or width and a symmetry of the radiation.
  • the term "workplace” in this context may refer to a typically horizontal or quasi-horizontal surface on which certain activities occur.
  • the workstation may be a table surface, and in particular a surface of an office or desk. Or it can be an area of a room with or without one or more tables. Also, it can only be part of a table such as a conference table in a boardroom.
  • targeted illumination in the context of the workplace may refer to the generation of a preferred light distribution curve (LVK).
  • the workplace should be sufficiently brightened and glare should be avoided.
  • the targeted illumination does not create a lighting of the workplace via a basic lighting in the room, but a specific illumination of the workplace, which is independent of the basic lighting.
  • the illumination of the workplace differs from the basic lighting of the room.
  • the workplace should often be illuminated brighter to allow comfortable reading and writing or working.
  • pure workplace lighting or a combination of workstation and basic lighting can be achieved.
  • the term "light beam” or luminous flux or beam can refer to a stream of visible light. This may be light emitted by a luminaire or light source and in particular visible light emitted by a light emitter.
  • the light beam or beam may be a beam, wherein ray bundles are understood to mean a number of light rays which run exactly or approximately parallel to one another or also predominantly in a similar direction. In this case, the light beam can also have a propagation angle, as typically occurs in point light sources.
  • the light can be controlled locally, for example, to a wall or a workplace. Or there may be intermediate values (dynamic light distribution curve) are generated. Alternatively or additionally, lighting moods can also be controlled, for example by the percentage setting of the directed and / or diffuse light component.
  • the cladding element is designed to reflect at least 60% or at least 75% of the light beam directed onto the cladding element. In particular, this can be ensured in all embodiments of the cladding element.

  • a dematerialized light or a virtual light on the ceiling or the wall can be generated.

For example, in rooms in which the workstations change regularly, a purposeful lighting can be done, which can be adapted to the changes with relatively little effort, for example, a simple repositioning of the trim element. For example, this can prevent the ceiling lights from being suspended and / or standing or floor lamps having to be changed over in order to enable adapted lighting of the room or of the individual workplaces in the event of changing conditions.
  • the inventive cladding element allows new possibilities in interior design.
  • the virtual light can be perceived as a built-in light, without actually installation would be necessary.
  • the cladding element further allows workspaces to be suitably illuminated in rooms in which no installation or installation of light in or on the ceiling is possible.
  • ceiling lights can be generated on ceilings, which are not enough powerful for installation, which are too unsustainable for installation or cultivation or may not be changed, for example, denkmalticianrischen reasons.
  • no electrical connection to the ceiling is needed.
  • the ceiling can be completely de-energized, which is often advantageous and can prevent a relatively expensive ceiling construction.
  • the lighting system may be advantageous even at relatively low ceiling heights, since no superstructures protrude from the ceiling.
  • Next can be used efficiently with the cladding element ceilings for lighting, which have a relatively low reflectance and thus would have a relatively large energy consumption, if they were used for lighting via reflection.
  • the cladding element according to the invention can have the following advantages:

  • the maintenance and installation can be relatively simple.
  • a luminaire object can be generated over the corner, which may be preferred in certain applications.
