Definitions

  • the invention relates to a lighting fitting comprising a supporting part of coupling part and a screen part which at least partly surrounds the light source.
  • the invention has for its object to provide a lighting fitting of the kind set forth in which the direction of the light can be simply adjusted at will with the aid of the co-operation between the supporting part and the screen part.
  • Fig. 1 shows a lighting system comprising four supporting parts 1, which can be suspended to a ceiling or the like with the aid of rods 2 fastened to said supporting parts 1. Between the supporting parts are arranged screen parts 3, the ends of which are in contact with the ends of the supporting parts 1 facing the screen parts concerned.
  • Fig. 2 and 3 shows that in the embodiment shown a supporting part is formed by a round tube length having on its inner surface a plurality of T-section extensions 4 at equal intervals along the periphery.
  • the screen part 3 comprises a wall portion 5 in the form of an arc of a circle, said wall portion 5 bounding between its free ends a slot 5' extending in the direction of length of the screen part.
  • L-shaped extensions 6 extend in the direction of length of the screen part so that the limbs of the L-shaped extensions spaced apart from the wall portion are directed towards one another away from the limbs adjoining the wall portion 5.
  • two relatively parallel strips 9 and 10 may be used for fastening an end of a screen part 3 and an end of a supporting part 1 to one another.
  • these strips can co-operate with two T-shaped extensions 4 of a supporting part 1 so that the strip 9 is locked between the wall of the supporting part 1 and the proximal parts of two neighbouring extensions as is shown in Fig. 3, whilst with the aid of a screw 11 passed through a hole in the strip 10 and screwed into a tapped hole in the strip 9 the strip 10 is clamped with the strip 9 to the parts of T-shaped extensions 4 located between the strips 9 and 10.
  • an end of the strip 9 protruding beyond the supporting part 1 can be slipped in between the wall 5 of the screen part 3 and L-shaped parts 6 fastened to the inner side of said wall, whilst then the end of the strip 10 protruding beyond the supporting part 1 will be in contact with the sides of the proximal limbs of the L-shaped parts 6 remote from the wall 5.
  • the strips 9 and 10 will be clamped by further fastening screws 11 to the parts of the T-shaped extensions 4 and the L-shaped extensions 6 respectively located between the strips 9 and 10.
  • the screen parts accommodate light sources formed by tubular lamps 12. These lamps can be coupled with one another by means of plugs and counterplugs or be cdupled with the aid of a connection member arranged in the supporting part 1.
  • Fig. 1 It is furthermore shown in Fig. 1 that by turning the screen part 3 with respect to the supporting part 1 the direction of illuminating can be set. In the arrangement of the outermost left-hand screen part shown in Fig. 1 the light is radiated downwards, whereas at the outermost righthand screen part 3 the light is radiated upwards. In the arrangement shown for the middle screen part 3 the light is radiated to one side.
  • Fig. 5 shows two lighting fittings 13 and 14 comprising lengths of tube 18 and elbows 19 adjoining the former.
  • the elbows may be provided with extensions corresponding with the extensions of the first embodiment so that in the same manner as described above a screen part 20 can be arranged between the proximal ends of the elbows 19 forming supporting parts. It is then again possible in a simple manner to set the screen part 20 in a desired position so that, for example, as is shown for the fitting 13 the light is radiated downwards, or, as is shown for the fitting 14, the light can be radiated to one side, for example, towards a wall.
  • the construction embodying the invention may be designed for a table lamp 21 as shown in Fig. 5.
  • the table lamp comprises a corner piece 22 having internal extensions 23 corresponding with the extensions 4 (Fig. 6).
  • a screen part 26 corresponding with the screen part 3 can be fastened at the end of the corner piece 23 with the aid of connecting strips 24 and 25, which screen part can be fixed in a desired position relative to the support 22 in order to obtain the desired direction of illumination.
