Definitions

  • the invention relates to a lighting 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.
  • 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 a possible optimal 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.
  • Such surface lights can be made relatively small and focused or larger and wider luminous.
  • WO 2013/102862 A1 describes an illumination system with a light emitter and a reflector to be mounted on a room deck. The light emitter emits a luminous flux to the reflector, which reflects it in the direction of a workstation.
  • ceiling lights lighting systems can be preferably illuminated and although such lights or reflectors are relatively little disturbing, since they are not located in places where things are placed or persons are, they are relatively inflexible.
  • such ceiling lights or reflectors are usually too inflexible, since they must be umgeenfin, reoriented and configured. They are also often undesirable for interior design, as they are typically fixed and therefore can not be redesigned.
  • the object of the following invention is therefore to propose a lighting system which allows a flexibly adaptable and configurable, specific illumination of workplaces in a room.
  • An illumination system comprises a light emitter, a workstation and a ceiling.
  • the light emitter is designed to emit a stream of visible light to the ceiling.
  • the ceiling is designed such that the stream of visible light emitted by the light emitter to the ceiling creates a luminaire object with predefined luminous properties on the ceiling.
  • the luminaire object on the ceiling illuminates the workplace.
  • ceiling may refer to an upper boundary of a room in the context of the invention. Not necessarily but typically ceilings are aligned horizontally. They may be formed by plastered masonry, panels, stretched textile materials, metals or the like.
  • the Room ceiling can be the ceiling of a closed or open space. In particular, it can describe a homogeneous surface as delimitation of the roughness upwards.
  • the “light emitter” as provided in the illumination system typically comprises at least one light source, in particular an LED light source and an optic with which the light emitted by the light source is adjusted or adjusted.
  • the light source together with the optics generates the stream of visible light.
  • the term "current of visible light”, which is also referred to herein simply as “luminous flux” or “beam” refers to visible light emitted by the light emitter.
  • the luminous flux or beam can be a bundle of rays, wherein ray bundles are understood to mean a number of light rays which run exactly or approximately parallel to one another or else predominantly in a similar direction.
  • the luminous flux can also have a propagation angle, as typically occurs in point light sources.
  • the light emitter can be relatively compact and easily realized, for example, as a stele or Lichtstele.
  • the term "texture" in the context of the ceiling can refer to a composition of the ceiling, their color, texture or the like.
  • the nature of the ceiling can define their reflection properties and their emission characteristics.
  • the ceiling can be designed in various ways to be suitable for the production of the luminaire object.
  • the ceiling can be a mirror ceiling or contain mirrors.
  • the luminous flux can be used relatively directly and unchanged to produce the luminaire object, so that the luminaire object itself can deliver a directed luminous flux.
  • the ceiling can be equipped with a lime plaster, which allows the generation of a luminaire object that gives off comparatively diffused light.
  • the ceiling is equipped with a light directing structure.
  • the light directing structure allows the luminous flux to be directed, whereby the radiation characteristics of the reflected light can be adjusted or determined. It may in particular be a microstructure or nanostructure.
  • the Ceiling can also be equipped with a light-directing paint, anodized, with a galvanic coating or similar.
  • the ceiling preferably has predefined reflective properties.
  • predefined reflection properties the luminous properties of the luminaire object produced on the ceiling can be adjusted and defined relatively precisely. Also, such predefined reflection properties allow sufficient light emission through the luminaire object.
  • the ceiling is formed partially diffuse or diffuse reflective.
  • a preferred lighting can be achieved in many applications, in particular for illuminating workplaces.
  • a total area of the ceiling is preferably at least three times or at least five times larger than an area of the luminaire object.
  • a predominant part of the ceiling is not provided with the luminaire object.
  • the luminaire object can be designed in this way, not to provide a basic lighting in the room, but to specifically illuminate a destination such as the workplace.
  • the luminaire object can be efficiently and flexibly generated at a selected location on the ceiling
  • the ceiling is substantially uniform.
  • the ceiling in the luminaire object is preferably the same as outside the luminaire object.
  • the ceiling is preferably made substantially continuously from a same material.
  • Such a ceiling allows a flexible arrangement or generation and positioning of one or more luminaire objects.
  • the ceiling itself can be used directly for the production of the luminaire object, which increases the degrees of freedom in the application and simplifies the use of the lighting system.
  • the luminaire object is materially bonded to the rest of the room ceiling. This can be achieved in particular efficiently if the Luminaire object is generated directly to the ceiling, without an additional element must be attached to it. Thus, a flexible indirect lighting can be provided in a simple manner with relatively little effort.
  • the term "workplace” 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.
  • predefined lighting properties in the context of the luminaire object can refer to the fact that the characteristics of the luminous flux and the nature of the ceiling, the luminous properties are set specifically for the illumination of the workplace.
  • the luminous properties of the luminaire object can be predefined in such a way that a light distribution curve (LVK) specifically provided for the workstation involved is achieved.
  • LLK light distribution curve
  • targeted illumination in the context of the workplace may refer to the generation of a preferred 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. For example, the workplace should often be illuminated brighter to allow comfortable reading and writing or working.
  • luminaire object refers to a particularly homogeneous or even inhomogeneous closed light surface with a defined boundary or sharp Edge.
  • the luminaire object can have any shape on the ceiling. In particular, it may be formed round or polygonal on the ceiling.
  • the luminaire object can be designed or adjusted so that the light surface does not have a homogeneous luminance distribution. This can for example be higher in the center.
  • the human eye does not necessarily have to perceive this, but it can be noticeable in the workplace. This allows you to adjust the illuminance between the wall and the table. The two extremes can be called “center beam” and "ring beam”.
  • a maximum luminance of about 1,500 cd / m 2 or a maximum of about 2,500 cd / m 2 or a maximum of about 3,000 cd / m 2 the brightness can not exceed 30% or a maximum of 20% or maximum Change 10% or a maximum of 5% or a maximum of 3% in the luminaire object.
  • An illuminance of the luminaire object may be at least about 300 lux or at least about 500 lux.
  • the term "defined limit” is understood to mean a decrease in the luminance on the ceiling to at most 10%, at most 5% or virtually 0%, exceeding a maximum of about 30% of a diameter or a maximum of about 15% of a radius of the luminaire object or a center zone thereof.
  • the center zone may be an area of the luminaire object which is not to be assigned to the defined boundary, ie to a border zone.
  • the center zone may be a homogeneous light surface or may, for example, have a luminance gradient away from the center toward the edge zone.
  • the diameter may be an approximate diameter for non-circular shapes of the luminaire object. For example, it may correspond to a square shape of a diagonal of the square.
  • sharp edge in this context is understood to mean a decrease in luminance of at least about 20%, at least about 25%, at least about 30%, at least about 40% or at least about 50%, preferably to about 0% a maximum of about 10% of the diameter of the luminaire object or a center zone thereof takes place.
  • the luminaire object can be a spot or any other form of luminaire.
  • the lighting system according to the invention enables the creation of a dematerialized light or a virtual light on the ceiling by means of the luminaire object.
  • the ceiling itself is used as a component of the lighting system to illuminate the workplace.
  • the creation of such a virtual light allows great flexibility in the lighting and design of workstations. For example, in rooms in which the workplaces change regularly, targeted lighting can be carried out, which can be adapted to the changes with relatively little effort. For example, it can be prevented that suspended ceiling lights and / or free-standing or floor lamps must be changed in order to allow for changing conditions each one adapted lighting of the individual workstations. Rather, with or without re-aligning and possibly re-adjusting the light emitter, a workstation at another location in the room can be re-illuminated.
  • the inventive lighting system allows new possibilities in interior design.
  • the virtual light can be perceived as a built-in light, without actually installation would be necessary.
  • the lighting system also makes it possible to suitably illuminate workplaces in rooms in which it is not possible to install or install luminaires in or on the ceiling.
  • ceiling lighting can be generated on ceilings, which are not enough for installation, which are not sufficiently sustainable for installation or cultivation or may not be changed, for example, denkmalticianrischen reasons.
  • no electrical connection to the room deck is needed.
  • the lighting system can be advantageous even at relatively low room heights, since no structures protrude from the ceiling.
  • the illumination system according to the invention can have the following advantages:
  • the luminaires or the light emitters can be made relatively flexible, since no large luminaire head is necessary.
  • the indirect lighting over the ceiling, as it is generated in the inventive lighting system can be perceived as particularly pleasant.
  • light graphics can be generated.
  • the illumination system according to the invention a self-adaptive Workplace lighting can be realized in real-time without the need for any changes.
  • the lighting system according to the invention may be preferred in interior design, since no stand or larger luminaire objects must be placed in the room. There is no shadow generated by direct light.
  • the light produced can come close to the impression of daylight, which is often perceived as pleasant.
  • the maintenance and installation can be relatively simple.
  • the light emitter can also direct the luminous flux on one or more walls of the room and thus also produce on this one or more walls a typically associated with the luminaire object of the ceiling space lamp object.
  • Such luminaire objects over the corner may be preferred in certain applications.
  • a further freedom of design (degree of freedom) for the interior design can arise.
  • the illumination system according to the invention thus enables a flexibly adaptable illumination specifically of workplaces in a room. Also, it can be implemented relatively efficiently and inexpensively.
  • the light emitter is stationarily connected to the workstation. It can for example be integrated in a table leg of a desk or attached to the edge of a table top of the office table.
  • the light emitter can be moved with the workstation or office table or mitwandern. As a result, the luminaire object is moved along the ceiling equally and regardless of where the workplace is positioned in the room, the lighting system provides a convenient lighting. This allows a very flexible and easy lighting of workplaces.
  • the light emitter on an actuator with the properties of the luminous flux can be adjusted.
  • the setting unit for example, the light color and / or the intensity can be adjusted. This allows the creation of a customized and well-defined luminaire object on the ceiling.

  • the setting unit can allow a change in the focus and the emission angle. With the focus the edge sharpness of the luminaire object and with the angle the size of the luminaire object can be adjusted.
  • the lighting system preferably comprises a monitoring unit which is connected to the setting unit of the light emitter, the monitoring unit being designed to monitor the workstation and to activate the setting unit when the workstation changes, the setting unit setting the visible light output in such a way that that the illumination of the workplace by the luminaire object on the ceiling remains constant.
  • the change in the workplace can be, for example, a move of the workplace or the desk.
  • a change in the height of the desk may be a change in the workstation that is monitored and detected by the monitoring unit.
  • the light emitter can be fixedly arranged in space. When changing the workplace, the luminaire object on the ceiling can be changed automatically, so that the illumination of the workplace remains constant. The lighting system can thus automatically adjust the lighting situation, the virtual ceiling light, for example, mitwandern with the workplace and thus ensure a constant illumination.
  • the monitoring unit preferably comprises a sensor which detects the position and / or the orientation of the workstation.
