Definitions

  • the present invention relates, in general, to a lighting device with a compact structure, and also with immediate lighting and a high energy saving.
  • the invention relates to a compact fluorescent lamp to which an incandescent or halogen light source is added to improve the lighting time and average life duration.
  • Energy-saving fluorescent lamps of the "CFL” type are becoming increasingly more widely diffused on the market, thanks to the high performances which they are capable of reaching; in particular, these lamps are capable of allowing a good 80% energy saving with the same light flow emitted and also the useful life of "CFL” energy saving fluorescent lamps can increase by as much as 10 times with respect to traditional lamps.
  • Figure 1 enclosed shows, for illustrative purposes, the trend of the light flow F in relation to the time t, revealed on an energy-saving light bulb of the 20 W "CFL" type.
  • This effect is particularly unwelcome, especially in places where the permanence time of the user is short, for example bathrooms, corridors, landings, etc.
  • An objective of the present invention is therefore to overcome the above drawbacks and, in particular, to provide a lighting device with a compact structure, which has a substantially limited consumption and which therefore allows a high energy saving and which, at the same time, allows the nominal lighting level, which is a typical characteristic of incandescent light sources, to be reached almost immediately.
  • a further objective of the present invention is to provide a lighting device with a compact structure, with immediate lighting and high energy saving, which is also extremely safe and highly reliable.
  • Another objective of the invention is to provide a lighting device with a compact structure at substantially reduced costs, in view of the advantages obtained.
  • the invention advantageously envisages combining an incandescent or halogen light source having a suitable power with a fluorescent light source, in order to obtain a twofold contribution in immediately reaching a satisfactory light flow equal to about 80% of the nominal value.
  • Incandescent or halogen light sources in fact, reach a nominal emission in a few ms. and also produce a considerable quantity of heat.
  • this shows an experimental graph relating to the trend, with time, of the light flow (reference FL1) emitted from a lighting device with a compact structure, produced according to the present invention, and compared with the trends of the light flow emitted from a standard energy-saving fluorescent lamp (reference FL2) and a halogen lamp (reference FL3) respectively.
  • the experimental result shown in figure 2 is obtained by producing the lighting device with a compact structure, object of the invention, according to a first constructive embodiment, which is shown in detail in figures 3, 4 and 5 enclosed.
  • the embodiment proposed is to envisage the use of two lamps assembled on a single central containment structure 10, in support of the lower electric contact 11.
  • an incandescent or halogen lamp 13 equipped with an outer bulb 14 and internal filament 15, is installed more internally and centrally with respect to the tube 12.
  • an electronic circuit situated inside the structure 10 interrupts the power supply to the incandescent or halogen lamp 13, so that at this point both the current absorptions and light flow are those characteristic of the fluorescent source (tube 12).
  • the advantages of the incandescent or halogen sources are combined with those of the fluorescent sources, as the lighting device according to the invention allows the nominal lighting levels (typical characteristic of the incandescent or halogen source 13) to be reached immediately and, at the same time, with a reduced consumption with respect to the other types of light sources, and a consequent energy saving and long functioning period (typical characteristics of the fluorescent tube 12).
  • the graph of figure 2 shows, in fact, that the lighting device according to the invention immediately reaches 80% of the nominal flow (reference FL1).
  • FIG. 6 An alternative embodiment, which is more complicated but less costly and more effective with respect to that described above, is illustrated in detail in figures 6, 7 and 8 enclosed and envisages the fluorescent light source (tube 12) and the incandescent or halogen light source 13 inside a single cap 16, which acts as a containing element for the fluorescent tube or coil 12 and is also functional for the filament 15 of the incandescent or halogen lamp 13, in that it ensures the formation of the vacuum necessary for the functioning of the above incandescent or halogen filament.
  • This second embodiment also complete with an electronic circuit suitable for interrupting the power supply to the incandescent or halogen lamp 13, once the nominal light flow emission has been reached, can also guarantee a more rapid establishment of the operating temperature.
