  • a Micro grid a grid or prism element as a light influencing element 6 are inserted.
  • the light exit surface 21 is in turn configured to be crystal clear in this case. Also the basis of the Fig. 3 to 8 variants described would be conceivable for the formation of a light exit element for the directed light emission.
  • the side walls 22 of the first sub-element 20, however, are preferably designed diffusely radiating, as over this side walls emitted light should be scattered as possible in different directions.
  • the second sub-elements 25 are like the first sub-element 20 pot-shaped, so have a lower light exit surface 26 and side walls 27. Since the second sub-elements 25 define the second radiating surface B, however, it is now provided that all walls of the second sub-elements 25 are designed to be light-scattering, so that these elements thus act completely as diffusers.
  • a special feature of this lamp 1 is now that at least one of the two sub-elements 20, 25, preferably both are adjustable in the light emission direction.
  • all the elements 20, 25 such that they are flush with the luminaire housing 2 and thus with the surrounding ceiling area.
  • the two lateral second sub-elements 25 could be arranged protruding.
  • light is emitted diffusely via the side walls 27 of the second partial elements 25, so that surrounding ceiling areas are brightened.
  • the preferred directional light emission to the underside takes place via the first subelement 20.
  • the area surrounding the first sub-element 20 is brightened over the lower sides 26 of the second sub-elements 25.
  • Fig. 11 Alternative to the configuration in Fig. 11 could also be provided that the first sub-element 20 is arranged above, while on the other hand, the second sub-elements 25 terminate flush with the lamp housing 2. Also at this in Fig. 12 The effect for brightening surrounding ceiling areas here, however, is significantly lower, since these side walls 22 are arranged further away from the edge regions of the lamp housing. Despite everything, positive photometric properties are also achieved in this variant.
  • the possibility of adjusting the sub-elements in the light-emitting direction can in turn be opened by suitably connecting them with the Side walls of the lamp housing 2 can be latched. A corresponding screwing in the desired position can also be provided.
  • a luminaire is created by the present invention, which on the one hand is easy to clean and accordingly has a high maintenance factor.
  • at least comparable positive photometric properties as in already known luminaires are achieved.
  • the ceiling area surrounding the luminaire can additionally be brightened. The photometric properties of the luminaire according to the invention are thereby even further improved.
