Definitions

  • the present invention relates to a closure assembly, particularly for lamps, ceiling lamps and light sources in general.
  • a lamp is generally constituted by an enclosure (lamp body) within which the circuit for supplying power to the actual light source is contained, and a reflector on which the source is accommodated (so as to direct the light flow towards the objective).
  • the enclosure (lamp body) generally comprises a transparent portion, generally termed screen (aligned with the light source and with the reflector), through which the light flow exits from the enclosure (lamp body). In some cases instead of the transparent portion, or screen, there is an actual aperture for the same purpose.
  • opening the reflector i.e. detaching it from the enclosure/lamp body
  • tools for example a screwdriver
  • the opening can also be done without using any tools: in this case the design choice will dictate suitable shapes of the parts in play, shapes geared to the specific purpose of facilitating the manual opening, and which will perceptibly affect the final appearance of the product.
  • the reflector can normally be opened only by using a tool, thus determining a high risk of scratching it, thus compromising the aesthetic appearance of the lamp and, in some cases, also the light yield.
  • the aim of the present invention is to solve the above mentioned problems, by providing a closure assembly, particularly for lamps, ceiling lamps and light sources in general, which allows the removal of the reflector of a lamp without the use of tools and utensils.
  • an object of the invention is to provide a closure assembly, particularly for lamps, ceiling lamps and light sources in general, which ensures the maximum possible surface for the reflector of the lamp without therefore impinging on its dimensions in any way.
  • Another object of the invention is to provide a closure assembly, particularly for lamps, ceiling lamps and light sources in general, which has a considerable aesthetic value and is particularly efficient in use in terms of simplicity of assembly/disassembly and ergonomics.
  • a further object of the present invention is to provide a closure assembly, particularly for lamps, ceiling lamps and light sources in general, which is low cost, easily and practically implemented and safely applied.
  • a closure assembly particularly for lamps, ceiling lamps and light sources in general of the type that comprises an enclosure, generally termed lamp body, an electric circuit for supplying power to the light source, and a reflector, which is coupled to the enclosure and is interposed between at least one portion of said circuit and said light source, characterized in that said reflector comprises at least one cantilever portion, which is partially movable as a consequence of elastic deformation of its tab that is jointly connected to the reflector, provided with a lower protrusion, which in the assembly configuration is aligned with, and proximate to, the internal surface of said enclosure, and is provided, at its tip, with a prong, said enclosure comprising a frame which is shaped complementarily to said prong for its detachable engagement in the closure configuration.
  • the reference numeral 1 generally designates a closure assembly, particularly for lamps A, ceiling lamps and light sources in general.
  • the lamps A (or ceiling lamps and light sources in general) to which reference shall be made hereinbelow comprise an enclosure 2, generally termed lamp body, an electric circuit for supplying power to the actual light source (neither of these components are shown in the accompanying figures), and a reflector 3, which is coupled to the enclosure 2 and is interposed between at least one portion of the circuit and the light source.
  • the reflector 3 has the outward-facing surface thereof, with respect to the enclosure 2 (if the enclosure 2 is closed by a transparent protection screen then this refers to the surface of the reflector 3 facing this transparent screen), of the optically reflecting type: the purpose is to reflect the entire luminous radiation outwards (optionally through the transparent screen), thus maximising the light yield of the lamp A.
  • the reflector 3 comprises at least one cantilever portion 4, which is partially movable as a consequence of elastic deformation of its tab 5 that is jointly connected to the reflector 3.
  • the portion 4 is provided with a lower protrusion 6 which in the assembly configuration is aligned with, and proximate to, the internal surface of the enclosure 2.
  • the lower protrusion 6 is provided, at its tip, with a prong 7.
  • the enclosure 2 comprises a frame 8 which is shaped complementarily to the prong 7 for the detachable engagement of the prong 7 in the frame 8, thus defining a stable closure configuration.
  • the cantilever portion 4 is delimited by a peripheral through slot 9, which is arranged and located between the ends of the tab 5 that is jointly connected to the reflector 3.
  • the cantilever portion 4 has a substantially rectangular contour (when viewing its shape with respect to the reflector 3 in plan view); the tab 5 that is jointly connected to the reflector 3 thus constitutes one of the short sides of the rectangle.
  • the protrusion 6 has a stiffening rib 10 the thickness of which decreases starting from its part that is aligned with, and proximate to, the reflector 3, to its end, thus defining, with one of its faces 11, an inclined plane that is interrupted exclusively by the recess 12 located upstream of the prong 7.
  • the cantilever portion 4 (in reality there will always be a plurality of portions 4 which cooperate in order to obtain a correct locking of the reflector 3 onto the enclosure 2) is arranged at a perimetric region of the reflector 3: by locking the edges of the reflector 3, its central part that supports the light source will definitely be effectively locked as well.
  • the cantilever portion 4 (or the portions 4 that cooperate in order to obtain the locking) is arranged at a corner of the reflector 3: indeed, the reflector 3 that is coupled to the enclosure 2 at its four corners will certainly be firmly and stably coupled thereto.
  • the surface of the cantilever portion 4 that is exposed when the reflector 3 is in the assembly configuration has the same coloring and the same optical reflection characteristics as the remaining part of the reflector 3. This makes it possible to have a surface that is continuous reflecting, as well as very broad, while also having the benefit of closure assemblies 1 that can be manually actuated, i.e. without having to resort to any utensil or tool.
  • the surface of the cantilever portion 4 that is exposed when the reflector 3 is in the assembly configuration comprises adapted raised portions 13 which, protruding from the surface of the portion 4, facilitate pushing by the user who wishes to uncouple the prong 7 from the frame 8 of the enclosure 2.
  • the raised portions 13 could effectively and in an equivalent manner be substituted with bosses or other extensions of any nature of this surface.
  • the reflector 3, provided with at least one cantilever portion 4 provided with a lower protrusion 6 with an end prong 7, is made monolithically by means of a molding process.
  • the assembly 1 according to the invention is therefore particularly simple from an implementation point of view in that it does not require the assembly of additional components once the reflector 3 has been extracted from the mold.
  • the disassembly and assembly operations of a reflector 3 of a lamp A provided with the closure assembly 1 according to the invention starting from the active closed condition of the lamp A, involve the pressing of each cantilever portion 4 arranged proximately to the perimetric edge of the reflector 3.
  • the reflector 3 is released and free to move with respect to the enclosure 2; it is thus possible to extract the reflector 3 for the necessary operations of maintenance, cleaning, replacement, checking and the like.
  • the reflector 3 has to be pressed in its seat which is present in the enclosure 2 of the lamp A, so that the inclined surface of the prong 7, and of the lower protrusion 6 in general, rests and slides on the edge of the frame 8 until the prong 7 moves beyond the frame 8, with consequent elastic snap action of the portion 4 into the non-deformed configuration as a consequence of the engagement of the frame 8 in the recess 12 arranged upstream of the prong 7.
  • the present invention solves the problems of the background art, by providing a closure assembly 1, particularly for lamps A, ceiling lamps and light sources in general which allows the removal of the reflector 3 of a lamp A without the use of tools and utensils.
  • closure assembly 1 ensures the maximum possible surface for the reflector 3 of the lamp A without therefore impinging on its dimensions in any way.
  • closure assembly 1 has a considerable aesthetic value and is particularly efficient in use, in terms of simplicity of assembly/ disassembly and ergonomics.
