  • the width of the fourth aperture 122 is chosen such that the first electrical conductor 110 is not electrically connected thereto. This is similar to the design of the second aperture 116.
  • an electrically insulating material (not shown) may be provided in the space defined between the outer surface of the first electrical conductor 110 and the inner surface of the fourth aperture 122.
  • a light emitter 108 may be inserted into the construction panel 100 from either side thereof, as the electrical conductors 110,114 will each only be connected to one of the electrically conducting front plate 102 and the electrically conducting rear plate 104.
  • Fig. 3 discloses one way of using the construction panel 100 in that it is attached to a grid-like structure 124 such that it is inserted into the square spaced defined by this structure 124. It will be appreciated that in this way, the construction panel 100 may be moved from one square space to another.
  • Fig. 4 discloses another way of using the construction panel 100 in that the panel it self is suspended from the ceiling 126 by means of wires. This provides the advantage that the construction panel 100 may be positioned closer to e.g. a table.
  • a plurality of light emitters are provided which defines a first zone which is encirculated by a second zone of light emitters.
  • the beam angle of the light emitters of the first zone is wider than the beam angle of the light emitters of the second zone.
  • the beam angle of the light emitters of the first zone is narrower than the beam angle of the light emitters of the second zone.
