Definitions

  • the present invention relates to the field of lighting items, in particular to non-integrated, energy-efficient lamps of fluorescent type.
  • fluorescent lamps are encountering increasingly vast distribution and will soon completely replace the traditional incandescent lamps.
  • the benefits introduced by fluorescent lamps lie in their increased life and in the energy efficiency that they permit to achieve.
  • the lighting quality provided by these lamps is now widely comparable with that of incandescent lamps.
  • a problem which is still related with fluorescent lamps is the overall dimensions. Indeed, fluorescent lamps generally have larger dimensions than the corresponding incandescent lamps, and sometimes this is an obstacle for installing them in ceiling lights or in lamps having small dimensions. This is particularly true in connection with lamps having ends of type G24d, G24q, GX24d and GX24q. Indeed, the lighting apparatuses equipped with lamps of this type all have large dimensions. This factor is not only a drawback in terms of appearance, although it is significant, but especially from the technical point of view, as the larger the lighting apparatuses, the more they lose efficiency due to their failure to recover passive reflections.
  • the present invention relates to a fluorescent lamp having varying overall dimensions, comprising a support and connection base in turn comprising two separate parts which are free to reciprocally move about a connecting hinge so as to vary the overall dimensions of the lamp itself.
  • the lamp usually comprises a glass bulb 10 containing the gas (generally a krypton and neon mixture) which, due to the excitation received by a part of the electrons emitted by a powered cathode, generates a light radiation, and a base 11 made of insulating material adapted to mechanically support said bulb 10 and to house said mechanical and electrical means to be connected to the intended lamp-holder.
  • the gas generally a krypton and neon mixture
  • Said base 11 made of insulating material, preferably made in plastic material, such as for example PVC, in turn comprises two separate parts, the first part 12 being associated with said glass bulb 10, the second part 13 being associated with said means to be connected to the intended lamp-holder, preferably provided with a connector 14 equipped with one end compatible with standards G24d, G24q, GX24d and GX24q.
  • Said two separate parts 12, 13 are hinged to each other and free to pivotally move with respect to each other about the connecting hinge 15 which will also house the electric leads between said two parts 12, 13. Moreover, said two parts will be equipped with reversible hooking means and adapted to keep them in a "closed" position, one above the other, as shown in accompanying Fig. 2 .
  • Said reversible hooking means preferably comprise a tongue 16 integral with said second part 13 of said base 11 and provided with a central opening, and a tooth 17 integral with said first part 12 of said base 11 and adapted to reversibly engage said central opening of said tongue 16.
  • Fluorescent lamps and in particular lamps having ends of type G24d, G24q, GX24d and GX24q, are normally installed in a horizontal position inside flush-mounting ceiling apparatuses in which the lamp-holder is also in the horizontal position.
  • a certain distance is required between the end of the lamp glass bulb and the wall of the lamp-holder, in order to facilitate the insertion of the lamp into the lamp-holder.
  • ceiling lights may also have smaller dimensions and may also be installed where the available space is small and, moreover, they may allow a more efficient lighting such as to allow a considerable energy efficiency.
  • the insertion of the lamp according to the present invention into the corresponding lamp-holder occurs by inserting connector 14 into the counterpart contained in the lamp-holder when said two parts 12, 13 are in the "open" position as shown in accompanying Fig. 1 .
  • the lamp insertion is easier and the manoeuvring space required by traditional lamps is not needed.
  • the aforesaid two parts 12, 13 are closed again, mutually secured by means of said reversible hooking means, and the lamp is ready to be used.
  • the inverse manoeuvre as compared to the one described is carried out for removing the lamp from the lamp-holder.
  • said glass bulb may also be constructed with a tube of the "twister" type having smaller dimensions than tubes of equal power and linear type. This allows a further saving in terms of overall dimensions of the lamp.
