Definitions

  • Lighting device comprising a movable sensing unit
  • the present system relates to energy conservation through the use of lighting control technology and more particularly to limiting the use of lighting when and where needed.
  • a global occupancy sensor to control a group of lighting devices, based on general occupancy information, and local occupancy sensors which are located close to local lighting devices and which control a local lighting task area, based on local occupancy information.
  • One or more controllers manage each lighting device, based on these two types of occupancy information, while typically giving priority to the local occupancy information over the general occupancy information when a local occupancy is detected, so as to illuminate a local area when needed.
  • the lighting task and control thereof may be specific for each lighting device, depending on the environment or the required application of each lighting device.
  • a purpose of the invention is to provide a lighting device having a tunable control of the task light, allowing to take into account the environment and/or the required application of the lighting device.
  • Another purpose of the invention is to enable such control tuning to be performed easily, by using a simple tool.
  • the invention attempts to achieve these purposes by proposing a lighting device according to claim 1.
  • the tuning system is adapted to change a relative position or an orientation of the sensing unit with respect to the open housing.
  • the tuning system is adapted to change a relative position or an orientation of the sensing unit with respect to the opening of the open housing, and more specifically with respect to the surface of the opening of the open housing.
  • the tuning system is adapted to modify the task area, and in particular its size, shape and/or orientation.
  • the tuning system allows changing the viewing angle of the sensing element through the opening of the housing and therefore the surface or volume of the local task area monitored by the sensing element.
  • the local illumination can be controlled in a tailored way, based on the tuning of the sensing unit with respect to the housing.
  • a tuning system may change the position and/or orientation of the sensing unit and/or the position and/or orientation of the housing. In both cases, a change of the task area monitored by the sensing element is achieved.
  • the lighting device is according to claim 3.
  • the central reference of the monitored task area is not changed, only the size of the task area is modified.
  • the sensing unit by positioning the sensing unit at a larger distance from the opening of the housing, the user of the lighting device can reduce the viewing angle (and so the task area) of the sensing element through the opening. Accordingly, an occupancy sensed before this repositioning of the sensing element is not necessarily sensed after the repositioning.
  • the task area monitored by the sensing element is therefore tuned by its user to take into account the specific environment (e.g. open plan offices with reduced gaps between desks, outdoor lighting for road to street lighting) or of the specific application (e.g. a lighting device used in a restaurant to illuminate a large table and a lighting device used in a library to illuminate the books to be read).
  • the invention proposes a lighting device according to claim 4 or 5.
  • This tuning system allows very easy positioning of the sensing unit and therefore easy tuning of the task area to be monitored by the sensing element.
  • the housing is easy to manufacture and the tuning system is quite simple to make.
  • the invention proposes a lighting device according to claim 6.
  • the orientation of the monitored task area is modified (i.e. the central reference of the task area is displaced).
  • the volume or surface of the task area is also modified due to this rotation of the sensing unit with respect to the open housing (and with respect to the surface of the opening) and the size of the task area is slightly modified as well (indeed, the viewing angle is also modified due to the tilting of the sensing element with respect to the opening surface of the open housing).
  • the user of the lighting device may obtain an asymmetric task area which can help to monitor a required specific task area.
  • This option may be particularly useful if several sensing elements are used in the lighting device and the user wants the lighting device to monitor an overall task area constituted by a plurality of specific task areas, each specific task area being monitored by one specific sensing element. Indeed, the tuning of the orientation of the specific task area enables the user to cover the overall task area in an accurate and efficient manner.
  • the rotation can be performed around an axis or a point (by using a ball pivot as recited in claim 6).
  • the tuning system comprises a translational tuning system according to claim 8 or 9.
  • This tuning system may therefore combine rotation and translation of the sensing unit with respect to the open housing, resulting in additional possibilities for the user as to the choice of the task area to be monitored by the sensing unit: sizes, shapes and orientation of the task area can therefore be tuned accurately and with substantial freedom.
  • the rotational tuning system is activated at one translational position in case the rotational tuning system is not translated with the sensing unit (e.g. the rotational tuning system may be activated only if the sensing unit is at a high position) or it is activated at any position of the sensing unit if the rotational tuning system is moved together with the sensing unit (as recited in claim 8).
  • the option according to claim 10 allows easy positioning of the sensing unit, and also allows easy manufacture thereof.
  • the lighting device is according to claim 11.
  • Such shielding should improve the control of the limits of the task area, increase the control of the illumination accordingly and prevent interferences with other task areas.
  • the option of claim 12 improves the user manipulation of the tuning system and therefore of the tuning of the sensing unit.
  • the option of claim 13 enables manual driving of the tuning system and/or using an electrical driver (for instance an electrical motor) to adjust the position and/or orientation of the sensing unit.
  • an electrical driver for instance an electrical motor
  • Corresponding user interfaces can therefore be provided with the lighting device enabling performing this adjustment more easily.
  • the option of claim 14 allows full integration of the sensing unit and the tuning system into the luminaire. Moreover, this option allows to hide this assembly in the luminaire, or at least results in a discrete localization in the luminaire. This option should therefore provide an important aesthetical advantage for this luminaire, while ensuring tunability and sensitivity of the sensing unit.
  • the option of claim 15 allows integration of the lighting device into a network of lighting devices which provide general illumination and independent and tunable task lighting.
  • Fig. 1 shows two lighting devices, each controllable from two sensing units, said sensing units being arranged to sense occupancy within a determinate task area.
  • Fig. 2 shows an example of an electrical circuit which might be used in the lighting device according to the invention.
  • Fig. 3 shows a translational tuning system for tuning the position of a sensing unit in a lighting device.
  • Fig. 4 shows a lighting device integrating two sensing units, each sensing unit being positioned at different elevation positions, and accordingly monitors two different task areas.
  • Figs. 5, 6 and 7 show respectively various translational tuning systems which may be used to position the sensing unit in the lighting device.
  • Figs. 8 and 9 show a rotational tuning system used to rotate a sensing unit with respect to an axis or a point, to two rotational positions.
  • Fig. 10 shows an example of a tuning system which allows a sensing unit to be positioned and orientedin a lighting device.
  • Fig. 1 shows two luminaires 1 and , each comprising light sources 90, 90' arranged for downward illumination, two sensing units 10 and 10' lodged at the bottom surface 21 of the head of the luminaires 1, 1', and comprising a sensing element to sense waves (e.g. sound, electromagnetic waves) representative of presence and/or motion within the respective task area 100, 100' ; and control systems 80, 80' arranged to couple the light sources 90, 90' with the sensing units 1 such that the light can change depending on the sensing of presence and/or motion by the sensing units 10,10'.
