Definitions

  • This invention relates to a lighting fixture for fixed installation, preferably for outdoor use.
  • a lighting fixture for fixed installation has a base, usually designed to be fastened to a wall or a ceiling, which is adapted to house the lighting source and the electric and/or electronic components required to assure the operation of the lighting source.
  • the lighting source is covered by a generally box-like metal lid, in which apertures are formed to allow light to pass therethrough.
  • the metal lid of such fixture is usually made by die-casting of light alloys.
  • the mold is already shaped with apertures for light passage.
  • the internal components of the lamp are protected from weather by closing such apertures with transparent elements, typically glass plates or lenses.
  • these apertures have a recessed periphery, for supporting glass plate edges and for receiving a suitable sealant, typically silicone thereon.
  • the glass plate supporting groove is formed on the outside of the metal lid.
  • the main object of this invention is to obviate at least some of prior art drawbacks and particularly the above mentioned drawbacks.
  • numeral 1 generally designates a lighting fixture for fixed installation.
  • Such fixture comprises a base 2 having a plurality of support feet 4.
  • Each support foot 4 has a hole 5 for receiving fastener means, e.g. screw fasteners.
  • the base 2 may be fastened to a wall, a ceiling or a suitably shaped metal framework.
  • such holes 5 have a circular shape, with an eyelet 14 - or two eyelets 14 disposed on two orthogonal axes - to assist mounting of the base 2.
  • the base 2 of the fixture includes a cavity 3, which contains the electric and/or electronic components of the fixture, such as voltage transformers, ballasts, terminal strips, fuses, batteries, etc.
  • the base 2 also has an electrical and mechanical socket for at least one lighting source 8, e.g. a filament lamp, a quartz-iodine lamp, a neon lamp or a discharge lamp.
  • a lighting source 8 e.g. a filament lamp, a quartz-iodine lamp, a neon lamp or a discharge lamp.
  • the cavity 3 has a generally and/or substantially rectangular shape and its opening size is larger than its depth.
  • a hole (not shown) is also provided on a side wall or on the bottom of the base 2, allowing the passage of a power cord with a strain relief.
  • the base 2 has an outer frame 9, whose function will be better explained hereafter.
  • the fixture further includes a lid 6, which is removably joined to the base 2 with an interposed seal 19.
  • the lid 6 has a cavity 26 whose opening faces toward the cavity 3 of the base 2.
  • the lid 6 and the base 2 define a closed space for enclosing the lighting source of the fixture.
  • the lid 6 has two external parallel elongated projections 16 at its edges.
  • Two locking brackets 20, 21 are further provided, which engage the outside projections 16 of the lid 6, while exerting a pressure against the seal 19.
  • the locking brackets 20, 21 are in turn connected to the outer frame 9 of the base 2 by reversible connector members, such as screws inserted in threaded holes 28.
  • the seal 19 is received in a groove 12 extending all around the cavity 3 of the base 2.
  • a feature of the fixture consists in that the lid 6 is made of a transparent and/or translucent material, typically glass.
  • the lid 6 has a generally box-like shape, with an open side and the four side walls of the lid 6 are slightly inclined, typically to 5° relative to the vertical plane, whereas the top wall of the lid 6 may be flat or slightly concave.
  • This arrangement is preferred when the lid 6 is made by molding, as the inclination of the side walls facilitates the removal of the lid from the mold.
  • a reflector element (not shown) may be placed inside the cavity 3 of the base 2 and/or the cavity 26 of the lid 6, for directing light emission toward the lid 6 or a portion thereof.
  • the lighting apparatus may also have an opaque screen 22, removably joined to the base 2 by reversible fastener means 30.
  • the reversible fastener means are screws 30 to be tightened in threaded holes 29 formed in the outer frame 9.
  • the threaded holes 29 have their axis parallel to the plane of the opening of the cavity 3.
  • the screen 22 partly covers the transparent and/or translucent glass 6 and the base 2, and therefore allows to create specific desired lighting areas, and to customize the exterior appearance of the fixture.
  • the screen 22 is shaped in such a manner as to only accomplish the function of covering, at least partly, the base 2.
  • two opaque screens 22 may be provided.
  • the screens 22 may also have louvers 23 to provide particular lighting effects.
  • the opaque screens 22 are rectangular U-bent metal sheets.
  • the screen 22 is made from stainless steel sheet and its outer surface may be painted or satin finished.
  • the apertures and the opaque screens 22 may be simply and inexpensively customized, e.g. by using laser cutting machines.
  • the base 2 may be made from aluminum or an aluminum alloy, the latter arrangement being preferred, amongst other things, in that is provides a light-weight fixture, which is sturdy and able to withstand the high temperatures generated by certain lighting sources.
  • the aluminum alloy (or aluminum) base 2 may be surface-treated, e.g. by anodic oxidation, thereby providing a very hard anticorrosive and partly electrically insulating coating, or painted with powdered paints, after a special pre-treatment for outdoor use.
  • the threaded holes 28 and 29 may be provided as stainless steel threaded bushings.
  • This arrangement prevents weather corrosion from making the removal of the fixture difficult with time.
  • the above described fixture is typically mounted to a wall or a ceiling.
