Definitions

  • the present invention relates to a device for indirect lighting in conjunction with a suspended ceiling structure which includes suspended sections as a support and panels supported thereon, the device comprising channel means disposed such that an out-of-sight or shielded, longitudinally extending channel is formed which is open in one direction for the emission of light, and in which longitudinally extending light fittings are disposed for the emission of light through the opening in said channel towards adjacent roof or wall portions to provide indirect lighting.
  • the suspended ceiling structure has a transition in levels where said channel means is provided.
  • prior art lighting devices of the abovementioned type have separate channel members attached to a portion of the wall some distance from the suspended ceiling which occasionally causes installation problems.
  • Fittings typically fluorescent light fittings, are mounted in line in the longitudinal direction of the channel using various types of special attachments. The respective ends of the lights thus end up being separated from each other by not insubstantial distances which has been found to give rise to shadow effects and/or uneven light distribution which, in many cases, can be regarded as disturbing.
  • US-A-4,569,004 discloses a device for indirect lighting in conjunction with a suspended ceiling structure.
  • the device comprises a channel means having a channel with longitudinally extending light fittings and with an upwardly directed channel opening for the emission of light.
  • the channel means comprises a frame structure carrying ceiling material and forms an integrated transition between two ceiling levels.
  • the object of the invention is to provide an improved lighting device of the type described in the introduction whereby indirect lighting adjacent the transition between levels in a suspended ceiling can be provided in a simple and effective manner, even in light wells, and whereby the above drawbacks can be avoided. At the same time additional benefits can be attained, in the form of integration of the lighting into the suspended ceiling structure itself, increased flexibility and better capacity for variation when it comes to setting up the light distribution.
  • the lighting device of the invention is essentially distinguished in that said channel means comprises a section integrated into the suspended ceiling structure and employed for connecting the component ceiling panels in the transition between levels of the suspended ceiling. Furthermore, the light fittings are disposed overlapping each other in the longitudinal direction of the channel such that their fields of illumination overlap each other. It thereby becomes possible to control and vary the overall distribution of light in a simple and effective manner, in that varying degrees of overlap between fittings, varying relative positions of the channel and fittings etc can be provided, as will be further illustrated below.
  • the light fittings can be permanently mounted in the channel, it is advantageous in the practise of the invention if the light fittings are individually translatably adjustable in the longitudinal direction of the channel. It will be appreciated that the mutual positions and degree of overlap of the fittings can thus be simply adjusted or altered and at the same time the task of wiring up and connecting is facilitated in many cases. Fittings which are to sit at an end of the channel, a position which in many cases is not within easy reach for mounting work, can be simply moved on to their final position after being initially placed in the channel and wired up at a place where this can be done without obstruction or other difficulties.
  • Arranging the light fittings in at least two rows parallel to the longitudinal direction of the channel has been found to be advantageous.
  • the light fittings in a first row are disposed on mounting units which are secured to, or supported by, a first "side” wall (in the broad sense) or the “bottom” (in the broad sense) of the channel, while a second row of light fittings are disposed on mounting units which are secured to, or supported by a second, opposed “wall” of the channel, broadly speaking, and the channel bottom.
  • a first "side” wall (in the broad sense) or the “bottom” (in the broad sense) of the channel while a second row of light fittings are disposed on mounting units which are secured to, or supported by a second, opposed “wall” of the channel, broadly speaking, and the channel bottom.
  • An advantageous embodiment has mounting units of an angled strip configuration with a first part extending generally crosswise relative to the channel and a second part extending generally depthwise in the channel.
  • the terminating edge portion of said second part of the mounting unit can be guided in a longitudinally extending groove adjacent the channel bottom while the terminating edge portion of said first part of the mounting unit can be secured by a securing means which, at a desired position, engages a longitudinally extending groove in the respective side wall of the channel, said second parts of the mounting units preferably bearing against each other where they overlap and preferably being guided in the same groove in the channel bottom.
  • Fig. 1 is a schematic, side view of an embodiment of a device according to the invention.
  • Fig.2 is a schematic, perspective view, partly in section, of the device of Fig.1 in which certain parts have been omitted for the sake of clarity.
  • Figs. 1 and 2 illustrate, by way of example, a device in accordance with the invention for the indirect suspended ceiling lighting of a transition in ceiling levels, in the form of a sloping ceiling panel 1 which forms a continuation of a lower lying horizontal ceiling panel 3.
  • Panels 1 and 3 are only schematically indicated as they can be of conventional design.
  • Ceiling panels 1 and 3 are supported by a section 5 which is of unitary fabrication and is integrated into the suspended ceiling structure.
  • the section 5 is suspended in a conventional fashion with an inverted, capital T-shaped suspending element 7 which is only schematically indicated because it is of no significance to the invention, either.
  • the section 5 Towards its bottom, the section 5 has a horizontal flange 6 for supporting the horizontal ceiling panel 3 and towards its top has a projecting receiving portion 8 for the sloping ceiling panel 1, which in the illustrated embodiment forms an angle of about 45° with the horizontal.
  • the flange 6 and receiving portion 8 project outwardly in generally opposite directions.
  • the section 5 defines a channel 9 having an upwardly directed opening which provides the desired release profile from the, in this case fluorescent, light fittings 11, 12, mounted in the channel 9.
  • the section 5 has a generally concave configuration and can be said to have two opposed channel side walls 13, 14 and a channel bottom 15.
  • Side wall 13 is essentially a freely projecting, upwardly curving section portion while side wall 14 is essentially a vertical downward continuation of the suspending element 7.
  • a number of fluorescent light fittings 11, 12 are mounted in two parallel rows within the channel 9 of the section 5 in such a fashion that successive fittings lie in alternate rows and that adjacent fittings overlap each other, as illustrated in Fig. 2.
  • An overlap of the order of 10 - 20 cm, typically around 15 cm has been found suitable.
  • Each fitting is mounted on a separate mounting unit 21 and includes two fluorescent light holders 23, 24 secured at respective ends on the upper side of the corresponding mounting unit.
  • the fluorescent lights themselves have been omitted in Fig. 2.
  • other light fitting components can be mounted on the underside of the mounting unit 21.
  • the mounting units 21 are similar for all the fittings, although the mounting units are opposedly arranged in either row.
  • the mounting units 21 are formed from a right-angled strip having a first (in this case horizontal) plane 25 and a second (in this case vertical) plane 26.
  • the holders 23, 24 are secured to the first part 25 adjacent the transition to the second part 26.
  • the free edge portion 27 of the first part 25 is angled upward in the opposite direction from the second part 26 and functions as a support and securing portion as does the adjoining border portion of said first part 25.
  • the portions in question are equipped with holes 29, 30 for screw fasteners 31 and 32 respectively which can be screwed securely into respective cooperating longitudinally extending grooves 33 and 35 disposed adjacent the respective side walls 14, 13 of the channel.
  • the hole 29 in the upwardly angled portion 27 is used for the securing of the mounting unit 21.
  • the hole 30 in said bordering region of part 25 is used for the securing of the mounting unit.
  • the groove 35 runs in a projection 39 which provides a similar sort of support as the flange 37. Additional support can be provided by the cooperation of the angled up portion 27 with wall 13 directly or with a projection therefrom.
  • the second parts 26 of the mounting units bear against each other where they overlap. It should be appreciated that this in itself provides a stabilizing effect. Additionally, the lower free edge regions of the second parts 26 are guided and supported in a groove 41 in the bottom part 15 of the section 5.
  • the mounting units 21 can easily be given another form within the context of the selected mounting technique.
  • the height of the second part 26 can be altered and thus the location of the fitting in the channel 9 will be changed.
  • the mounting units 21 with fitting components mounted and electrically ready-connected can be simply placed in the channel 9 and electrically connected together, preferably in rows.
  • wiring up etc is facilitated by the access to the spaces under or within the mounting units in that the fittings in their respective rows end up being separated by considerable open spaces and by the general mobility of the mounting units.
  • the mounting units with fittings connected can be adjusted to the desired position and desired light distribution and securely screwed.
