Definitions

  • a place which is over illuminated on a street or a garden illuminated when natural light is already sufficient does not help to save energy.
  • the device according to the present invention affords an effective contribution to the saving of electric energy.
  • Figure 1 is illustrated a chandelier 3 in the rose 4 of which (see the section of Fig. 2) is inserted the device 1 according to the present invention from which device the bundle of optical fibres 2 projects which take and convey to the said device the light with the luminous intensity peculiar to the surroundings.
  • Figs. 3, 4, 5 show the assembly of the device in question comprising a pointed circuit 8 with the electronic components or the photo-electric cell 7, the bundle of optical fibres 2 with terminal 2', the holder 5, the cover 6 mounted.
  • the pointed circuit 8 is mounted in the holder 5 and the photo-electric cell 7 is illuminated by means of the bundle of optical fibres 2.
  • a device (not shown) for regulating manually the light which the terminal receives, or a connector for optical fibres 2' so that the said bundle may be extended for the manual or automatic regulation at a distance of the desired luminous intensity.
  • Fig. 6 shows one embodiment of the device for screwing into the existing lamp holder 9.
  • the device is similar to an additional lamp holder which is screwed into the lamp holder 9 and receives in its turn by screwing, the bulb.
  • On the inside is mounted the stamped circuit with the relative components illustrated in Fig. 9.
  • the optical rod 2 (Fig. 6) takes light to the outside to avoid the photo-cell 7 receiving the light from the bulb reflected by the shield 14. Without the rod towards the outside the bulb 10 would be extinguished immediately by its reflected light.
  • Fig. 7 shows the application of the device to fluorescent or neon lamps and for all types of street lamps etc. Electrically it is equal to the realization according to Figures 3, 4, 5 whilst the holder may vary from lamp to lamp and is adapted to the mechanical construction of the said lamp. It is a closed box 1 from which emerges the bundle of optical fibres 2 which receives light from outside.
  • Fig. 8 shows the diagram according to two different preferred procedures 12 and 13 of the power W absorbed from the lamp (ordinate) according to the luminous intensity of the surroundings Ia (abscissa). If the light of the surroundings increases the power W of the lamp decreases.
  • the lamp As can be seen from line 12 of the diagram besides a specific luminous intensity of the surroundings, the lamp (or the group of lamps) is extinguished completely and the power absorbed passes immediately from the point P to zero Watt.
  • the electrical resistance of the photo-cell Fl when it is blacked out is very high above 10 Mohm; since the resistance R4 also has a high value the current which passes through Rl is almost equal to the current which passes through R2 and C3 is charged for a very short time.
  • the luminosity of the lamp has under these conditions its maximum value. If the photocell is illuminated the value of its electrical resistance decreases and consequently more current circulates in it. The current which passes through the photocell is to be substracted from the charging current of the condenser C3 and the voltage at its ends increases more slowly and consequently the lighting of the triac is retarded.
  • the bulb 10 reduces its degree of luminosity proportionally to the electrical resistance of the photocell.
  • the fully illuminated photocell has an electrical resistance of about 500 ohm, the lamp 10 in these circumstances is almost extinguished.
  • the device in question to be capable of being incorporated directly in a chandelier or in any holder or lamp holder at the time of their manufacture or mounted at any point of the circuit feeding the bulb always located in the space illuminated by the said bulb all this without departing from the scope of protection of the invention.
