Definitions

  • the present invention relates to a lighting fixture suitable for outdoor wall-mounted installation.
  • the aim of the present invention is to obviate the cited shortcomings and meet the mentioned requirements, by providing a lighting fixture that has a simple structure, is relatively easy to provide in practice, safe in use, effective in operation, as well as relatively low in cost.
  • a lighting fixture comprising a base for supporting a light source and a lamina having a reflective surface, and a transparent screen, characterized in that said base comprises setting means, such as fixing holes, a plurality of feet, on the area that is adapted to make contact with the anchoring surface, and an engagement slot, on the side that lies upward after installation, said means being adapted to allow stable fixing directly to a wall or optionally to a plate applied to the wall beforehand.
  • the reference numeral 1 generally designates a lighting fixture according to the invention.
  • the reference numeral 2 designates a base, which constitutes the supporting structure of the lighting fixture 1 and is surmounted by the screen 3, which is made for example of clear polycarbonate with catadioptric surfaces, in order to optimize light diffusion.
  • the base 2 substantially has the shape of a tray, provided with a U-shaped peripheral rim 2b that has the dual purpose of giving greater rigidity to the base and of creating, on the central portion of the U-shape, a contact region for the screen 3 when the lighting fixture 1 is closed.
  • An underlying surface 2c is provided inside the peripheral rim 2b.
  • the underlying surface 2c of the base 2 is substantially flat, and a plurality of feet 2a protrude therefrom; said feet are adapted to ensure correct positioning of the lighting fixture 1 on the destination wall.
  • the underlying surface 2c has, on both faces, ribs that are designed to increase the rigidity of the entire base 2.
  • Bushings 2d are formed by molding on the inner side of the underlying surface 2c of the base 2; a lamina 4 with a reflective surface is fixed on the bushings 2d by means of screws 4e and has a flat surface in the lower and central portions of the lighting fixture 1 (with reference to the configuration assumed by the lighting fixture during use) and prism-shaped surfaces 4a, 4b, 4c and 4d in its upper portion, which are inclined with respect to the lower flat part and are adapted to gather and convey the beams of light that propagate in directions that are external to the theoretical incidence range of the lighting fixture 1.
  • the lamina 4 there is a protective enclosure 5, inside which part of the wiring of the lighting fixture is contained; the remaining part of the wiring is installed between the underlying surface 2c of the substantially flat base 2 and the lamina 4 having a reflective surface.
  • the wiring is not described in detail, since it does not have characteristics that differentiate it from the state of the art.
  • a lamp 6, of the compact fluorescent type, is installed in the lamp holder comprised within the enclosure 5.
  • the lighting fixture receives electrical power over a cable 7.
  • Elastic metallic laminas 8 are fixed, by means of the surface of their first end, to the base 2 by means of a screw coupling 8a.
  • Each metallic lamina 8 is obtained by means of cold working of a strip of metal plate that is characterized by good elasticity.
  • a first bend 8c radiused along a circular arc and obtained by rotating clockwise the part of the metal strip that remains after the first flat portion 8b, arranges a second flat portion 8d so that it forms an acute angle with the first portion 8b.
  • a third bending line 8e obtained by rotating counterclockwise the part of metal strip that remains after the second flat portion 8d, divides the second portion 8d from a third flat portion 8f, forming an obtuse angle between them.
  • a contoured shape 11 is formed which can be likened to a sequence of two semicircles in which the concavity of the first one faces downward and the concavity of the second one faces upward.
  • a seat 13 is adapted to accommodate the tool required to open the screen 3 if necessary.
  • the laminas 8 are arranged on the left and right sides in the case of installation on an optional plate, and are arranged on the lower side in the case of wall-mounted installation: they can be placed individually or in pairs, as shown in the figure.
  • the closure of the screen 3 on the base 2 is obtained by way of the interlocking on the pivots 9, provided at the upper part of the base 2, of the hook-like bodies 10, which are provided at the upper part of the screen 3, and by way of the elastic fastening provided by the laminas 8 after the insertion of the contoured portion 11, provided on the second end of each lamina 8, in a border 12 of the screen 3.
  • the laminas 8 adhere to the lateral surface of the rim 2b of the base 2 and to the outer surface of a lip 14 of the screen 3; the outer lip 14 is formed around the screen 3, is arranged perimetrically and, in the closed position, rests on the perimetric surface 15 of the base 2, outside the abutment 15a.
  • a ridge 16, parallel to the lip 14 and provided on the screen 3, is forced, upon closure, onto a perimetric gasket 17 that is accommodated within the slot 17a of the base 2.
  • An annular chamber remains between the lip 14, the ridge 16, the base 2 and the gasket 17 and runs along the entire perimeter of the lighting fixture 1.
  • the lamina 4 is coupled to the base 2 by screw fastening on a set of bushings 18 formed directly by molding on the base 2.
  • the lighting fixture 1 if fixed directly to the wall, is rigidly coupled thereto by means of the base 2, which has suitable provisions, shown in figure 5 in the form of setting means: in the specific case, said provisions are holes, suitably provided with gaskets, that ensure that the degree of protection against penetration of dust and liquids according to applicable statutory provisions that characterizes the fixture 1 is maintained.
  • the lighting fixture 1 can be mounted on a plate 19 for requirements of rapid disassembly during maintenance.
  • the plate 19 is provided by means of a suitably shaped metal plate, which must in turn be anchored to the wall by means of the wall anchors 20, which engage in the holes 20a provided in the plate 19.
  • a protrusion 21 is formed at the upper end of the plate 19 and is adapted to be accommodated in a slot 22 of the rim 2b of the base 2.
  • the lighting fixture 1 therefore is made to hang from the protrusion 21 through engagement of the slot 22: complete fixing is achieved by means of the toggle lever 23, whose free end is shaped so as to ensure grip within the peripheral border 12 of the screen 3.
  • the base 19 accommodates an electrical outlet 24 of a type prescribed by standards for outdoor use: the outlet 24 is directly connected to the electrical mains by means of a conventional electrical system, either an external one (in hermetic trunking) or a recessed one (inside the wall).
  • the lighting fixture 1 is provided with a plug 25 that is adapted to mate with the outlet 24, already wired at the end of the power supply cord 7.
  • the lighting fixture 1 for wall mounting, requires only that the holes provided in the wall be spaced correctly, since the base 2 is fixed to the wall by means of wall anchors that are arranged in said holes in the wall. Thereafter, it is merely a matter of connecting the cable 7 to a source of electric power and of positioning the screen 3; the screen 3 is fixed first by way of the hinge system, i.e., by inserting each pivot 9 within the respective semicircular body 10, then by means of the laminas 8, making the end provided with the contoured portion 11 snap within the peripheral border 12.
  • the assembly position is, with good approximation, planar thanks to of the presence of the plurality of supporting feet P.
  • the laminas 8 reopen by inserting a tool in a suitable seat 13 that is arranged on each lamina 8 and by forcing away from the screen 3.
  • the plate 19 For removable mounting, by using the plate 19, it is necessary to provide for the correct placement of the holes for the fixing of the wall anchors 20; the holes must be provided at the portion of wall faced by the holes 20a of the plate 19.
  • the lighting fixture 1 can then be positioned, after closing the screen 3 onto the base 2 by means of the laminas 8 arranged only on the lateral surfaces of the lighting fixture, by inserting the protrusion 20 in the slot 22, keeping the lighting fixture inclined and straightening it only once insertion has occurred; thereafter, it is sufficient to insert the free end of each toggle lever 23 in the peripheral border 12 and retract the fastening end of each lever into the closure position. As a final operation, it is necessary to insert the plug 25 already wired on the cord 7 into the outlet 24.
