  • the present invention relates to the field of lighting equipment . More particularly, the invention concerns a fluorescent lamp that incorporates an antitheft device, i.e. a device capable of preventing its unauthorized removal from the lamp holder. Description of the prior art
  • fluorescent lamps often also referred to as electronic lamps
  • electronic lamps are now being used to an ever greater extent on account of their smaller consumption and longer life and are gradually taking the place of the traditional incandescent lamps.
  • these lamps have a relatively greater first cost and for this reason are frequently stolen when they are installed in such public places as hotels, exhibition halls, and the like.
  • the object of the present invention is to provide a fluorescent lamp with an antitheft device that satisfies all the aforesaid requirements and, more particularly, proves capable of hindering the unscrewing of the lamp, thereby discouraging attempts to steal it, and to obtain all these results with an elementary structure that is versatile, easy to install and has negligible effects on the lamp's aesthetic appearance.
  • the fluorescent lamp in accordance with the present invention, which comprises a lamp body comprising a side wall and a bottom wall defining a chamber within which there are housed the electronic components that make the lamp function, the electric contacts being carried by a central appendix extending from said bottom; at least one fluorescent element extending from one part of said body and a screw base extending from the opposite part and surrounding said appendix, which projects from the end of the base.
  • the screw base is inseparably, yet pivotably, fixed to the lamp body and means are provided for making the body and the screw base pivotally integral , said means being activable when it is desired to screw the lamp into the lamp holder or unscrew it therefrom and deactivable to prevent unauthorized unscrewing.
  • the screw base is fixed to a centrally hollow dish-shaped member, said member, in its turn, being fixed to the lamp body by means of a snap attachment and capable of being rotated with respect to the body.
  • the dish-shaped member has at least one lateral pocket that, following an axial rotation of the dish-shaped element, can be aligned with an opening formed on said body, and a threaded element is engageable either partly or wholly within said pocket, the element in the former case being also engaged with said opening, when that opening is aligned with the pocket, whereby the body is made integral with the screw base, while in the latter case, being wholly disengaged from said opening, whereby the body is allowed to freely rotate with respect to the screw base.
  • FIG. 1 shows a bottom perspective view of the lamp in accordance with the invention as seen from below;
  • FIG. 2 shows a partially exploded view of the lamp of Figure 1
  • - Figure 3 shows another partially exploded view of the lamp of Figure 1;
  • FIG. 4 shows a section through the lower part of the lamp of Figure 1;
  • FIG. 5 shows a partial cross section of the lamp of Figure 1 without the screw base
  • the reference number 1 has been used to generically indicate a lamp body that comprises a side wall 2 and a bottom 3 and is closed at the top by a base 4 from which there extend fluorescent tubes of the conventional type.
  • Body 1 defines within it a chamber 6 in which there are housed the electronic components of the lamp, generically indicated by the reference number 7 and not here described in detail, because they are of the conventional type and do not come within the scope of the present invention.
  • side wall 2 of lamp body 2 is cylindrical and its bottom 3 has the shape of a truncated cone, as is in any
  • Appendix 8 is also provided with a second electric contact on its side, said contact being constituted by two blades 11 that extend from diametrically opposite points of the lateral surface of the appendix.
  • each blade 11 is provided with a pair of projecting tabs 11a, acting just as .electric contacts, and is arranged between two small ribs 12 formed on the lateral surface of appendix 8.
  • each blade 11 is formed with a central window 13 that engages with a lead-in projection 14 extending radially from the lateral surface of appendix 8.
  • each blade 11 is engaged at its upper end with a notch 15 cut in bottom 3 of lamp body 1, while a flap 16 at its lower end is bent inwards and rests against the edge of end 8a of appendix 8.
  • blades 11 are prevented from sliding in any direction, be it axial, circumferential or diametrical.
  • one of blades 11 is connected to the power supply of the lamp by means of an electric conductor 17, while the other blade has been provided only for obvious reasons of balancing the pressure forces exerted by projecting tabs 11a that serve as contacts.
  • second blade 11 could likewise be connected to the power supply of the lamp.
  • the lamp is provided with a conventional screw base 10, which according to the invention is attached to a dish-shaped element 18 comprising a tubular threaded portion 18a, to which screw base 10 is screwed and then fixed by means of mechanical seaming, and a dish portion 18b having the shape of a truncated cone and formed with two diametrically opposite pockets 19 sideways extending along the dish portion.
  • the two pockets are threaded on their inside in order to enable • them to accommodate respective threaded studs 20 having a length that does not exceed the depth of pockets 19.
  • screw base 10 comes to be irreversibly fixed to lamp body 1, though allowing the latter to be rotated with respect to screw base 10 and yet assuring electric contact by means of projecting tabs 11a that bear elastically against the inside of screw base 10.
  • Side wall 2 of lamp body 1 extends for a certain portion 2a around conical bottom 3 of lamp body 1.
  • lamp body 1 On this portion 2a of lamp body 1 there is formed a recess 22 that, thanks to the pivotal connection between screw base 10 and lamp body 1, can be brought into alignment with one of the two pockets 19 present on the conical portion of dish-shaped element 18.
  • lamp body 1 can either be locked to screw base 10 so as to rotate with it or be left free to rotate with respect to it.
  • stud 20 may be partially unscrewed to the point of becoming engaged with recess 22, as shown in Figure 1.
  • the lamp can readily be screwed into the lamp holder, and also removed from it, because lamp body lis integral with screw base 10 and rotates with it. But when stud 20 is completely screwed into pocket 19, as shown - for example - in Figure
  • lamp body 1 can obviously rotate with respect to screw base 10, so that any attempt to unscrew the lamp from its lamp holder is bound to fail .

Abstract

L'invention concerne une lampe fluorescente comprenant un corps (1) de lampe se composant d'une paroi latérale (2), d'une paroi inférieure (3) définissant un logement (6) dans lequel sont installés les composants électroniques (7) destinés au fonctionnement de la lampe, une partie annexe (8) supportant les contacts électriques (9, 11) et s'avançant à partir de ladite paroi inférieure, et au moins un élément fluorescent (5) s'avançant à partir d'une section dudit corps et une base filetée (10) s'avançant depuis la partie opposée et entourant ladite partie annexe, cette dernière se prolongeant au delà de la base filetée dans la direction axiale. La base filetée (10) est montée de manière définitive mais pivotante sur ledit corps, et la lampe comprend en outre des moyens (19, 20, 22) permettant d'assembler la base filetée de manière pivotante au corps, ces moyens pouvant être activés lorsqu'on désire visser la lampe dans un support de lampe correspondant, ou le détacher de ce dernier, et désactivés afin d'empêcher un dévissage non autorisé.
