Definitions

  • the present invention relates in general to lighting devices and more in particular, to a column lighting device of the so-called "bollard" type.
  • Yet another object of the present invention is to have a column lighting device which should be simple and inexpensive to manufacture and manage.
  • a lighting system of the so-called "bollard” type consisting of a support structure 1 with elongated shape in the top portion whereof there is formed an optical space 3 wherein a housing 5 is arranged for at least one light source 7.
  • the side surface of the optical space 3, through which the light is emitted outwards, consists of a light passage screen 9, made of shock resistant material and transparent to light, for example of glass or, preferably, of a plastic transparent material such as polycarbonate.
  • a reflector screen 17 with curved section Inside the optical space 3 of the column lighting device, immediately on top of bulb 15 of light source 7, there is arranged a reflector screen 17 with curved section, with concavity facing downwards.
  • the surface of the reflector screen 17 with curved section exhibits, proceeding from the centre towards the periphery of the reflector screen 17 itself, a first portion 19 that follows an ascending pattern, the remaining portion of the surface having on the other hand a descending pattern.
  • the surface portion 19 with ascending pattern has a shorter length, measured on the vertical section, as compared to that of the remaining portion of screen 17.
  • the reflector screen 17 is centrally pierced to be arranged around the light source 7 and is positioned for being, in operating conditions, immediately above bulb 15 of the light source 7 itself, so as to direct the light beams laterally downwards through screen 9.
  • the bottom portion of the side wall 13 of cap 11 exhibits an enlarged outer edge 21 which forms a little veil capable of screening all the light beams emitted above the horizontal plane passing through the centre of gravity of the transparent portion of screen 9 and/or further deviating the light beams emitted by source 7 and reflected by screen 17 downwards.
  • the tilt of veil 21 relative to wall 13 of cap 11 is variable according to the amount of light to be emitted through the transparent screen 9, while directing as much as possible such light towards the base of the support structure 1, but it is in any case such that angle ⁇ that forms between said veil 21 and said wall 13 is larger than 90°.
  • both the peripheral portion of the reflector screen 17, that is, that facing the transparent screen 9, and veil 21 of cap 5 are at a lower height than bulb 15 of the light source 7. Therefore, the light source 7 is completely screened relative to the horizontal plane passing through the centre of gravity of the transparent portion of screen 9, thus being impossible for the light emitted by said source 7 to cross the transparent screen 9 following a trajectory parallel to the ground or directed upwards. In this way, the light source 7 is completely hidden to an observer's view whose eyes are at a greater height than that of the transparent screen 9. Moreover, the particular tilt of veil 21, along with the bend of the reflector screen 17, allows deviating the light with particularly narrow angles for projecting it into the zones closer to the base of the support column 1 of the lighting device.
  • the column lighting device further envisages the presence, inside the optical space 3 that seats the light source 7, of a labyrinth consisting of a plurality of light absorbing screens arranged in a concentric manner, of honeycomb structures and of spongy material padding (not shown) that operate separately or in conjunction for preventing stray light beams from being directed upwards.
  • a labyrinth consisting of a plurality of light absorbing screens arranged in a concentric manner, of honeycomb structures and of spongy material padding (not shown) that operate separately or in conjunction for preventing stray light beams from being directed upwards.
  • the labyrinth is arranged in area A shown by a dashed line and is arranged below the horizontal plane passing through bulb 15. It comprises at least a first light absorbing screen 23, arranged circumferentially about housing 5 of the light source 7, a few distance therefrom and right below the bottom end of bulb 15.
  • the top edge of the light absorbing screen 23 is at a higher height than the bottom edge of veil 21, so as to further contribute to preventing light from being emitted from the lighting device according to the invention in a direction parallel to the ground.
  • the light absorbing labyrinth of the column lighting device comprises at least a second light absorbing screen 25, of generally cylindrical shape and arranged farther from the light source 7 and lower than screen 23 described above.
  • the top edge of light absorbing screen 25 is at a height equal to or higher than, the bottom corner of veil 21.
  • the function of the second light absorbing screen 25, which can also operate in combination with further screening walls and/or with padding of a spongy material, is to eliminate the forming of unpleasant signs that could form on the ground as a consequence of the unavoidable construction variability of the light sources usable and to increase the visual comfort.
  • all the surfaces inside the optical space are treated in such a way as to absorb light, so that only the desired amount of light is correctly directed, maximising the efficiency of the lighting device and completely eliminating stray reflection production phenomena.
  • the shapes of the lighting device of the invention may differ from that shown by way of a non-limiting example only in the figure, and the materials used may also be different on the basis of the different technical requirements.
