Definitions

  • the subject of the present invention is a wall-mountable lighting apparatus.
  • the illuminated area inevitably starts higher up with respect to the mouth of the illuminating apparatus, in such a way that the latter looks higher than it actually is; in other words, the virtual height of the lighting apparatus is decidedly greater than the actual height.
  • an attempt to solve this problem consists in setting, between the lighting apparatus and the wall, a plurality of refractive gratings which deflect the light towards the dark area.
  • a second known solution consists in mounting a screen in front of the lamp to limit the effect generated by the patches.
  • a purpose of the present invention is therefore to provide a lighting apparatus, of the wall-mountable type, which enables the elimination of sharp and anaesthetic discontinuities on the illuminated surfaces.
  • a further purpose of the present invention is to provide a lighting apparatus that enables the elimination of the difference between the virtual height and the actual height of the lighting element.
  • the lighting apparatus is designated as a whole by the reference number 10.
  • the lighting apparatus 10 is fixed, in a known way, for example by means of a bracket 18, to a wall 14, and comprises a casing 11, inside which a light source 12 is present.
  • a reflecting element 13 which may have a parabolic cross-section, is associated to the light source 12.
  • the lighting apparatus 10 is provided with a screen 15, which is set between the light source 12 and the wall 14.
  • the said screen 15 has an area designed to diffuse the light, for instance a satiny area 16, which, preferably, enables Lambert-type light emission.
  • the screen 15 has a transparent area 17 and a satiny area 16.
  • an area 17 is created which has no effect on the said Lambert-type emission, the screen (or bowl) not being inserted in the said area.
  • the area 17 is made using a transparent screen so as not to limit and/or modify light emission.
  • the Lambert-type distribution that the light assumes in the vicinity of the wall consequently enables the sharp transition between "dark and light” and the creation of unpleasant “streaks of light” to be prevented.
  • the satiny area 16 moreover makes it possible to deflect the light in such a way as to illuminate the entire wall 14 as far as the top of the lighting apparatus 10, thus reducing to the utmost the virtual dimensions of the lighting apparatus itself and eliminating the difference between the virtual height and the actual height of the illuminating element.
  • This solution also enables the elimination of the patches of light that are formed on the wall.
