Definitions

  • the present invention relates to a lighing device which comprises a support, a lighting element and a bulb which covers the ligthing element.
  • the invention relates also to an apparatus wherein these devices are used, such as standard lamps, abat- journeys or table lamps, chandeliers and appliques.
  • Prior art devices consist in for example, standard incandescent bulbs which have a cylindrical support where outside there is a thread able to be screwed to a corresponding bulb socket which is mounted on the above-mentioned apparatus such as standard lamps, abat- journeys, chandeliers and appliques.
  • a ligthing element which consits of an electric filament, is fixed to a cylindrical support and it is surrounded by a bulb which is also fixed to the cylindrical support.
  • LEDs Light Emitting Diode
  • LEDs Light Emitting Diode
  • LEDs are used simply as a direct source of light, for example at home where a plurality of LEDs directly light the environment.
  • This solution essentially consists in an incandescent bulb wherein the elettric filament has been replaced by a LED, namely it comprises a support wherein a thread is made to be screwed into a corresponding bulb socket, a LED fixed on the support and a transparent bulb firmly secured to the support, so as to form a sole integral body which actually forms a light bulb.
  • the aim of the invention is thus to generate a diffused lighting, thus allowing the lighting either of a room or an entire environment.
  • Another aim of the invention is to avoid the complete replacement of the light bulb in case of failures or malfunctionings with consequent savings, and also to avoid the production, warehouse storage and transport of new light bulbs, and the reduction of these costs.
  • a device as initially described, i.e. a lighting device comprising support means, at least one lighting element, and a bulb able to be mounted onto said support means and to surround said at least one lighting element, characterized in that said lighting element consists of at least one LED (Light Emitting Diode) and that said bulb and said support means are provided with detachable coupling means, so as to make said bulb manually removable with respect to said support means.
  • a lighting device comprising support means, at least one lighting element, and a bulb able to be mounted onto said support means and to surround said at least one lighting element, characterized in that said lighting element consists of at least one LED (Light Emitting Diode) and that said bulb and said support means are provided with detachable coupling means, so as to make said bulb manually removable with respect to said support means.
  • LED Light Emitting Diode
  • the replacement of the LED or the repair of the device is an extremely fast and simple operation. In case of failure of the LED, it is only sufficient to have a spare LED.
  • said detachable coupling means consists of a thread made on said support means and a corresponding thread made on said bulb, so as to form a screw coupling, so that it is possible to screw said bulb onto said support means.
  • the bulb is preferably semitransparent or translucent in order to generate a diffused lighting suitable for the lighting of an environment.
  • the invention also relates to a lighting apparatus comprising at least one stand having a first and a second end, in said second end a lighting device according to the invention is mounted.
  • the first end of said stand is fixed on a base suitable to be laid on the floor, on a table or on the wall, so as to form respectively a standard lamp, an abat- journey or an appliqe.
  • the first end of said at least one stand is fixed to a column, so as to form a chandelier.
  • the lighting device of the invention may be used in different ways, so as to form different kinds of lighting apparatus, such as standard lamps, abat- journeys, appliques and chandeliers.
  • a lighting device is wholly indicated with reference 10 which comprises a support 20, a radiant plate 30 with a LED 32 and a bulb 40.
  • the support 20 has essentially the shape of a hollow truncated pyramid delimited by a first end 20a defining a small base and a second end 20b defining a large base. Both the first end 20a and the second end 20b are opened.
  • a circular seat 22 is made on the second end 20b of the support 20 in order to house the radiant plate 30, as also represented in figure 1 .
  • a thread 24 is made on the outer surface of the second end 20b, for example a thread of Edison type, the function of which will be described in the following.
  • the radiant plate 30 has an essentially circular shape with dimensions lesser than those of the circular seat 22 of the support 20, so that it can be housed inside the seat 22.
  • the LED 32 is mounted in the center of the radiant plate 30.
  • the LED may be of different powers according to the required light intensity. For example, it may be of 4W electric power, sufficient to light even an environment of a large dimension. Therefore, the radiant plate 30 has the function to dissipate the concentrated heat generated by the LED and for this reason, along its circular profile, it has tabs which facilitate the cooling.
  • Electric wires which are not represented in figures, are connected to the LED 32 for the feeding and come out from the first end 20a of the support 20.
  • the bulb 40 comprises, in its turn, an ampoule 50 and a ring nut 60.
  • the ampoule 50 is preferably made of glass and it has a closed teardrop-shaped form with a circular opening 52 at its first end 50a opposite to a second end 50b ended with a point.
  • the ring nut 60 is inserted in the circular opening 52 and it is fixed for example by glueing or adhesive means.
  • the ring nut 60 has an inner circular opening 52 wherein a thread 64 corresponding to the thread 24 of the support 20 is made, so as to screw the ring nut 60 and the bulb 40 on the support 20.
  • the assembly and the disassembly of the device 10 is very simple.
  • the disassembly occurs inversely, by unscrewing the bulb 40 from the support 20.
  • the bulb 40 is semitransparent or translucent so that the strong and direct light of the LED 32 is diffused, creating a diffused brightness able to light an environment.
  • the bulb 40 may be white thus obtaining a white light, or it can be coloured and according to the colour of the bulb a light with different colours and shades can be obtained which is undoubtedly more warm.
  • the invention relates also to different lighting apparatus which is possible to construct with the lighting device 10, such as abat-jours or table lamps, standard lamps, appliques and chandeliers.
  • a table lamp 100 is illustrated as an example in figure 3 .
  • the table lamp 100 comprises three stands 102,104,106: stands 102,104,106 have a first end 102a,104a,106a fixed to a base 110 suitable to be laid on a table and a second end 102b,104b,106b on each end of which a support 20 is mounted and, then, the device 10 previously described.
  • the bulb 40 could not be provided with the ring nut 60, and the thread 64 could be made directly on the ampoule 50, thus eliminating a component, i.e. the ring nut 60, and in this case the ampoule 50 is screwed directly on the support 20.
