Definitions

  • the invention relates to a lighting system comprising
  • a lighting mode of the known lighting system is associated with a certain spatial distribution of the light in the room in which the lighting system is installed.
  • a user of the known lighting system can adapt the illumination of the room in which the lighting system is installed to his activities such as, for example, reading, watching TV, etc , through the choice of a suitable lighting mode.
  • the first group of the lighting units often supplies a comparatively high luminous flux intended for task lighting at the chosen location, while the luminous fluxes of the other lighting units belonging to a second group supply surround lighting.
  • lighting modes can also be selected attuned to situations in which more than one person uses the room. The different persons will in general perform different task in different locations.
  • the surround lighting is harmonized with the task lighting so that the overall illumination of the room makes a pleasant impression on the human eye.
  • This harmonization means that the luminous flux of the surround lighting must be chosen within a certain range, which range depends on the luminous flux value(s) in the chosen location(s).
  • the lighting modes are programmable in the known lighting system. This renders it possible to program lighting modes for widely differing rooms and for widely differing tasks, the surround lighting being harmonized with the task lighting.
  • the invention has for its object inter alia to provide a lighting system in which the user has the possibility of adjusting the desired luminous flux value in a chosen location over a wide range according to his preference and/or needs within a given lighting mode, while within this range a good harmonization of the surround lighting with the task lighting is maintained.
  • a lighting system of the kind mentioned in the opening paragraph is for this purpose characterized in that the control means are further provided with correction means for automatically changing the luminous fluxes of the lighting units belonging to the second group of lighting units in dependence on a change in the desired luminous flux value in the chosen location.
  • the surround lighting is adapted to the task lighting over a substantial portion of the adjustment range of the task lighting owing to the automatic adaptation of the luminous fluxes of the second group of lighting units upon a change in the desired luminous flux value in the chosen location.
  • a luminous flux substantially equal to the desired luminous flux value is generated in the chosen location substantially exclusively by the relevant lighting unit(s) belonging to the first group.
  • the luminous flux in the chosen location is not substantially exclusively determined by the luminous flux(es) from lighting units belonging to the first group, however, but also by daylight, it is advantageous to provide the lighting system with a control system for rendering the total luminous flux built up from the luminous flux of daylight and the luminous flux(es) of the lighting units of the first group substantially equal to the desired luminous flux value in the chosen location, independently of the luminous flux of daylight.
  • the luminous flux in the chosen location remains substantially constant in spite of fluctuations in the luminous flux of daylight in the chosen location.
  • the surround lighting is also to a high degree independent of the luminous flux of daylight in every lighting mode.
  • Such a lighting system is comparatively expensive.
  • a less expensive possibility is to provide exclusively those lighting units which can belong to the first group, depending on the selected lighting mode, with a control system, and at the same time to set the luminous flux of each lighting unit forming part of the second group for the lowest value in the range over which the luminous flux of this lighting unit in a given task lighting provides a surround lighting adapted to this task lighting.
  • An advantageous embodiment of a lighting system according to the invention is characterized in that the correction means comprise a memory for storing a chosen relation between the desired luminous flux in the chosen location and the luminous fluxes of the lighting units of the second group for each lighting mode of the lighting system.
  • the correction means can be constructed in a reliable and comparatively simple manner through the use of such a memory.
  • the memory comprises, for each lighting unit of the second group and for each desired luminous flux value in each chosen location, information about a luminous flux range of the lighting unit of the second group, and the correction means are provided with means for adjusting the luminous flux of each lighting unit of the second group to a value which belongs to each of the luminous flux ranges of the lighting unit in the case of a change in the desired luminous flux value in a chosen location.
  • the adjustment of the luminous flux of the relevant lighting unit of the second group to a value belonging to each range will guarantee that each user of the room experiences this luminous flux as pleasant.
  • the correction means are also provided with means for determining the lowest luminous flux value of each lighting unit of the second group which forms part of all luminous flux ranges of the lighting unit, the luminous flux of the lighting unit may be set for this lowest value, so that a surround lighting is realised which is well harmonized with the task lighting at a comparatively low power consumption.
  • the advantage described above is also achieved, i . e . the harmonization between task lighting and surround lighting is not disturbed even in the case of a comparatively large contribution of daylight to the surround lighting.
  • a further advantageous embodiment of a lighting system according to the invention is characterized in that the luminous flux of each lighting unit can be set for a number of discrete values. Since the desired luminous flux in the chosen location can be set for a finite number of discrete levels only in this further advantageous embodiment of a lighting system according to the invention, the correction means have to know the desired relation between task lighting and surround lighting only for this finite number of discrete levels, so that the correction means can be of a comparatively simple construction.
  • the correction means comprise a memory
  • the desired relation between task lighting and surround lighting may be laid down in this memory in a comparatively simple manner in the form of a table.
  • the adjustment possibility of the task lighting in practical terms is scarcely more limited than in a lighting system in which the task lighting can be varied continuously. It can also be achieved through a logarithmic increase of the luminous flux with the discrete levels that the change in luminous flux between two consecutive levels is experienced as constant by a user.
  • control means comprise first programming means for programming a desired relation between the desired luminous flux in the chosen location and the luminous fluxes of the second group of lighting units for each lighting mode of the lighting system.
  • the chosen relation between task lighting and surround lighting may be adapted to the room in which the lighting system is installed and to the use of this room as a result of this programming possibility. This renders the lighting system highly suitable for use in rooms of differing dimensions and widely differing purposes.
  • control means comprise further programming means for allocating a lighting unit to one of the groups of lighting units for each lighting mode.
  • These further programming means render it possible to select the lighting units belonging to the first group or to the second group over a wide range at will, for a given total number of lighting units forming part of the lighting system, whereby widely differing lighting modes can be programmed.
  • these further programming means offer a possibility of adapting the total number of lighting units which form part of the lighting system.
  • the possibilities of adjusting the lighting system optimally to the dimensions and intended use of the space in which it is used, during installation or at a later stage, are additionally widened by these further programming means.
  • control means comprise means for infrared communication between a user and the first and further adjustment means
  • a user of the lighting system can adjust a lighting mode in a comparatively simple manner and change the luminous flux(es) of one or several lighting units of the first group within a lighting mode.
  • communication between the user and the first and/or further programming means is also possible through the infrared communication means, a (re)installation of the lighting system by a user can be carried out in a comparatively simple manner as well.
  • the infrared communication means include repetition means for receiving infrared signals and for subsequently transmitting said signals in a unchanged form.
  • control means include means for communication with further control means for controlling the illumination of a group of rooms.
  • This group of rooms may be formed, for example, by the building in which the room containing the lighting system according to the invention is present. Since the control means communicate with the further control means, the lighting mode of the room in which the lighting system according to the invention is present is partly determined by the further control means which control the illumination of the building.
  • the application possibility of the lighting system according to the invention is thus expanded to rooms in buildings in which the lighting is controlled by a "building management system", which name is often given to these further control means.
  • control means it is also possible in a comparatively simple manner to couple the control means to a presence detection system for changing the lighting mode of the lighting system through the control means in the case in which nobody has been present in the room for an adjustable time interval.
  • the change in the lighting mode may consist, for example, in switching-off of the lighting system or in switching-on of a lighting mode in which the luminous fluxes of a number of lighting units are substantially zero or comparatively low. It is achieved by this that the lighting system consumes comparatively little electric power when the room is not in use.
  • reference numerals 1, 2, 3 ... n denote lighting units forming part of the lighting system.
  • Each lighting unit is provided with at least one lamp, an operating circuit for operating the lamp, and a control circuit for controlling the luminous flux of the lamp.
  • the lighting units are coupled to control means I for influencing the luminous fluxes of the lamps through the respective control circuits.
  • Control means I comprise first adjustment means II for selecting a lighting mode of the lighting system, further adjustment means III for changing a desired luminous flux value in at least one chosen location illuminated by at least one lighting unit belonging to a first group of lighting units within a lighting mode.
  • the control means I also comprise correction means IV for automatic correction of the luminous fluxes of lighting units belonging to a second group of lighting units in dependence on a change in the desired luminous flux value in the chosen location.
  • the operation of the lighting system shown in Fig. 1 is as follows.
  • a user When one or several users use a room in which the lighting system is installed, a user will set a lighting mode for the room with the first adjustment means.
