Definitions

  • the invention relates to a lighting system for illuminating a room with at least one workstation and preferably several workstations.
  • luminaires are used in different designs adapted to the respective application to illuminate rooms and workplaces.
  • the aim is usually to create light distribution curves with the luminaires that allow the best possible illumination when the luminaires are used as intended.
  • floor lamps are often used in offices to illuminate workstations such as desks. Although such lamps can sometimes provide good illumination for individual workstations, they can impair the use of the room and are often perceived as disruptive. In particular, such lamps typically have to be placed close to a workstation to ensure optimal illumination, which is often undesirable and particularly impractical for workstations that change regularly.
  • ceiling lights are also used to illuminate the workplaces.
  • surface lights suspended from the ceiling or built into the ceiling to specifically illuminate one or more workplaces.
  • Such surface lights can be relatively small and focused or larger and emit a wider light.
  • WO 2013/102862 A1 a lighting system with a spotlight and a reflector to be mounted on a ceiling is described.
  • the spotlight emits a luminous flux onto the reflector, which reflects it towards a workstation.
  • a comparable lighting system is known from the EP0735311A1 in which a light source placed close to the floor illuminates a reflector mounted close to the ceiling so that a reflected beam can be directed onto a work surface.
  • a light source illuminates a mirror element, the orientation of which can be changed by means of an adjusting device.
  • the mirror element is permanently mounted as a separate component of the lighting system near the ceiling.
  • adjustable, permanently mounted mirror elements can be used to achieve greater flexibility in light distribution.
  • the JP 2011 154830 A a lighting system is known in which a fixed spotlight can be directed to a separate reflection element, whereby the reflection element can be mounted and dismantled at an arbitrary location on a wall surface.
  • the US 2016/131316 A1 discloses a modular lighting system in which several light sources are individually controlled to illuminate a moving object. The light sources are mounted on adjustable mounting elements.
  • the US 4229782 A discloses a lighting unit comprising a lamp and a reflector which projects light in a limited beam angle range upwards onto a ceiling, from where the light is reflected onto a work area or a work surface below.
  • ceiling light systems can be used to illuminate workplaces in a preferential manner and although such lights or reflectors are relatively unobtrusive because they are not located in places where things are placed or people are present, they are relatively inflexible. Particularly in the case of workplaces that change regularly, for example in offices where workstation groups are formed depending on the project, such ceiling lights or reflectors are usually too inflexible because they have to be moved, realigned and configured. They are also often undesirable for interior design because they are typically permanently mounted and therefore cannot be redesigned.
  • the object of the following invention is therefore to propose a lighting system that enables a flexibly adaptable and designable, specific illumination of workplaces in a room.
  • a lighting system comprises a light emitter, a workstation and a ceiling.
  • the light emitter is designed to emit a stream of visible light onto the ceiling.
  • the ceiling is designed in such a way that the stream of visible light emitted by the light emitter onto the ceiling creates a lighting object with predefined lighting properties on the ceiling.
  • the lighting object on the ceiling specifically illuminates the workstation.
  • ceiling in connection with the invention can refer to an upper boundary of a room. Ceilings are not necessarily but typically aligned horizontally. They can be formed by plastered masonry, panels, stretched textile materials, metals or the like.
  • the A room ceiling can be the ceiling of a closed or open space. In particular, it can describe a homogeneous surface that separates the room from above.
  • the “light emitter” as provided in the lighting system typically comprises at least one light source, in particular an LED light source, and an optical system with which the light emitted by the light source is adjusted or adapted.
  • the light source together with the optical system generates the stream of visible light.
  • the luminous flux or beam can be a bundle of rays, whereby a bundle of rays is understood to mean a number of light rays that run exactly or approximately parallel to one another or predominantly in a similar direction.
  • the luminous flux can also have a propagation angle as typically occurs with point light sources.
  • the light emitter can be relatively compact and lightweight, for example as a column or light column.
  • condition can refer to the composition of the ceiling, its color, texture or similar.
  • condition of the ceiling can define its reflection properties and its radiation characteristics.
  • the ceiling can be designed in different ways to be suitable for creating the lighting object.
  • the ceiling can be a mirrored ceiling or contain mirrors. With such a ceiling, the luminous flux can be used relatively directly and unchanged to create the lighting object, so that the lighting object itself can emit a directed luminous flux.
  • the ceiling can be covered with lime plaster, which enables the creation of a lighting object that emits comparatively diffuse light.
  • the ceiling is equipped with a light-directing structure.
  • the light-directing structure enables the luminous flux to be directed, whereby the radiation characteristics of the reflected light can be adjusted or determined. It can in particular be a micro- or nanostructure.
  • the ceiling can also be coated with a light-directing paint, anodized, galvanized or similar.
  • the ceiling also preferably has predefined reflection properties.
  • predefined reflection properties the lighting properties of the lighting object created on the ceiling can be set and defined relatively precisely.
  • predefined reflection properties can also enable sufficient light emission through the lighting object.
  • the ceiling is designed to be partially diffuse or diffusely reflective.
  • Such a ceiling can be used to achieve preferred lighting in many applications, particularly for illuminating workplaces.
  • the total area of the ceiling is preferably at least three times or at least five times larger than the area of the lighting object. This means that a large part of the ceiling is not covered by the lighting object.
  • the lighting object can be designed in this way not to provide basic lighting in the room, but rather to specifically illuminate a target location such as the workplace.
  • the lighting object can be created efficiently and flexibly at a selected location on the ceiling.
  • the ceiling is essentially uniform.
  • the ceiling inside the lighting object is preferably the same as outside the lighting object.
  • the ceiling is preferably made essentially entirely from the same material.
  • Such a ceiling enables flexible arrangement or creation and positioning of one or more lighting objects.
  • the ceiling itself can be used directly to create the lighting object, which increases the degree of freedom in the application and simplifies the use of the lighting system.
  • the lighting object is integral with the rest of the ceiling. This can be achieved particularly efficiently if the A lighting object is created directly on the ceiling without the need to attach an additional element. This makes it easy to provide flexible indirect lighting with relatively little effort.
  • the term "workplace” can refer to a typically horizontal or quasi-horizontal surface on which certain activities are carried out.
  • the workplace can 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. It can also be just a part of a table, such as a conference table in a meeting room.
  • predefined lighting properties in connection with the lighting object can refer to the fact that the lighting properties are specifically determined for the illumination of the workplace via the properties of the luminous flux and the condition of the ceiling.
  • the lighting properties of the lighting object can be predefined in such a way that a light distribution curve (LDC) specifically intended for the workplace in question is achieved. Lighting properties that are present without being adapted or included in the determination of the illumination of the workplace are not to be understood as predefined in this sense.
  • LDC light distribution curve
  • targeted illumination in connection with the workplace can refer to the creation of a preferred LDC.
  • the workplace should be sufficiently illuminated and glare should be avoided.
  • Targeted illumination does not create illumination of the workplace via the basic lighting in the room, but rather a specific illumination of the workplace that 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 more brightly to allow comfortable reading and writing or working.
  • luminaire object refers to a particularly homogeneous or inhomogeneous closed light surface with a defined border or sharp Edges.
  • the lighting object can have any shape on the ceiling. In particular, it can be round or polygonal on the ceiling.
  • the lighting object can be designed or set up in such a way that the light surface does not have a homogeneous luminance distribution. This can be higher in the center, for example. The human eye does not necessarily have to perceive this, but it can be noticeable at the workplace.
  • the illuminance can be set between the wall and the table. The two extremes can be referred to as "center beam” and "ring beam”.
  • a luminance can be a maximum 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 change by a maximum of 30% or a maximum of 20% or a maximum of 10% or a maximum of 5% or a maximum of 3% in the lighting object.
  • the illuminance of the lighting object can be at least about 300 lux or at least about 500 lux.
  • the term "defined boundary" refers to a reduction in the luminance on the ceiling to a maximum of 10%, a maximum of 5% or virtually 0%, which occurs over a maximum of about 30% of a diameter or a maximum of about 15% of a radius of the luminaire object or a central zone thereof.
  • the central zone can be an area of the luminaire object that cannot be assigned to the defined boundary, i.e. a border zone.
  • the central zone can be a homogeneous light surface or it can, for example, have a luminance gradient from the center to the edge zone.
  • the diameter can be an approximate diameter if the luminaire object is not round. For example, if the shape of the luminaire object is square, it can correspond to a diagonal of the square.
  • the term “sharp edge” is understood to mean a reduction in luminance by 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%, wherein this reduction occurs over a maximum of about 10% of the diameter of the luminaire object or a central zone thereof.
  • the lighting object can be a spotlight or any other type of light.
  • the lighting system according to the invention enables the creation of a dematerialized light or a virtual light on the ceiling of a room by means of the light object.
  • the ceiling itself is used as a component of the lighting system to illuminate the workplace.
  • the creation of such a virtual light enables great flexibility in the lighting and design of workplaces. For example, in rooms in which the workplaces change regularly, targeted lighting can be provided that can be adapted to the changes with relatively little effort. For example, it can prevent ceiling lights from having to be moved and/or standing or floor lamps from having to be moved in order to enable adapted lighting of the individual workplaces when conditions change. Rather, a workplace at a different location in the room can be re-illuminated with or without re-aligning and, if necessary, re-adjusting the spotlight.
  • the lighting system according to the invention enables new possibilities in interior design.
  • the virtual light can be perceived as a built-in light without actually having to be installed.
  • the lighting system also enables workplaces to be appropriately illuminated in rooms in which it is not possible to install or add lights in or on the ceiling.
  • the lighting system can be used to create ceiling lighting on ceilings that are not thick enough to be installed, that do not have enough load-bearing capacity to be installed or added, or that cannot be changed for reasons of monument preservation, for example. No electrical connection is required on the ceiling.
  • the lighting system can also be advantageous in relatively low room heights, since there are no structures protruding from the ceiling.
  • the lighting system according to the invention can have the following advantages:
  • the lights or the light spotlights can be designed relatively flexibly, since no large lamp head is necessary.
  • the indirect lighting via the ceiling, as generated by the lighting system according to the invention can be perceived as particularly pleasant.
  • light graphics can be generated.
  • the lighting system according to the invention a self-adaptive Workplace lighting can be implemented in real time without having to make adjustments.
  • the lighting system according to the invention can be preferred in interior design, as no stands or larger light objects need to be set up in the room. No shadows are created by direct light.
  • the light produced can come close to the impression of daylight, which is often perceived as pleasant. Maintenance and installation can be relatively simple.
  • the spotlight can also direct the luminous flux at one or more walls in the room at the same time, thereby creating a lighting object on this one or more walls that is typically connected to the lighting object on the ceiling.
  • Such lighting objects across the corner can be preferred in certain applications.
  • the variability of the solid angle of the spotlight means that more of the wall can be illuminated and thus a higher vertical luminance can be achieved, which can be helpful for improving facial recognition, for example.
  • additional design freedom degree of freedom
  • the lighting system according to the invention therefore enables flexible, adaptable illumination specifically for workstations in a room. It can also be implemented relatively efficiently and cost-effectively.
  • the light spotlight is fixed to the workstation.
  • it can be integrated into a table leg of a desk or attached to the edge of a table top of an office table.
  • the light spotlight can be moved or travel with the workstation or office table. This means that the light object on the ceiling also moves in the same way and regardless of where the workstation is positioned in the room, the lighting system provides appropriate lighting. This enables extremely flexible and simple lighting of workstations.
  • the light emitter has an adjustment unit with which the properties of the luminous flux can be adjusted.
  • the adjustment unit can be used to adjust the light color and/or the intensity, for example. This enables the creation of an adapted and well-defined lighting object on the ceiling.
  • the adjustment unit of the light emitter is preferably designed to change the direction of the luminous flux. It is also preferably designed to change the focus of the luminous flux.
  • the light emitter can be equipped with a telescope, for example. In this way, the lighting object can be flexibly created on the ceiling and adapted to changing workplaces.
  • the adjustment unit can enable the focus and the beam angle to be changed.
  • the focus can be used to adjust the edge sharpness of the lighting object and the angle can be used to adjust the size of the lighting object.
  • the lighting system comprises a monitoring unit that is connected to the adjusting unit of the light spotlight, wherein the monitoring unit is designed to monitor the workplace and to activate the adjusting unit when a change in the workplace is detected, wherein the adjusting unit adjusts the luminous flux of visible light so that the illumination of the workplace by the lighting object on the ceiling remains constant.
  • the change in the workplace can be, for example, a shifting of the workplace or the desk.
  • a change in the height of the desk can also be a change in the workplace that is monitored and recorded by the monitoring unit.
  • the light spotlight can be fixed in the room. If the workplace changes, the lighting object on the ceiling can be automatically changed so that the illumination of the workplace remains constant.
  • the lighting system can therefore automatically adapt the lighting situation, the virtual ceiling light can, for example, move with the workplace and thus ensure constant illumination.
  • the monitoring unit preferably comprises a sensor that detects the position and/or orientation of the workstation.
  • the sensor can be designed in particular to detect movements of the workstation. This enables automated and rapid detection and recording of a change in the workstation.
  • the luminous flux emitted by the light source to the ceiling is a directed or partially diffused stream of visible light.
  • the lighting object on the ceiling can be created particularly precisely and efficiently.
