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.
  • Said devices comprise electronic members and at least one photo-cell, permitting of subduing the light of a lamp or group of lamps so as to emit light with a luminous intensity almost inversely proportional to the luminous intensity of the surrounding environment; the minimum luminous intensity of the lamp or of the group of lamps being capable of being predetermined and prere- gulated at any point of the characteristic of attenuation of the lamp.
  • the devices according to said prior art are provided with a photo-cell positioned in the housing of the lamp and receiving the light through a window of said housing.
  • the device according to the present invention is characterized in that it comprises at least one bundle of optical fibres, the external end of which is placed remote from the device, in order to receive only the light of the environment and to transmit it to the photo-cell.
  • Fig. 1 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 and 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 circuit with the relative components illustrated in Fig. 9.
  • the optical rod 2 (Fig. 6) takes the 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 Figs. 3, 4, 5 whilst the holder may vary from lamp to lamp and is adapted to the mechanical construction of 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 la (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 F1 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 R1 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 photo-cell is illuminated the value of its electrical resistance decreases and consequently more current circulates in it. The current which passes through the photo-cell is to be subtracted 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 photo-cell.
  • the fully illuminated photo-cell 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.

1. Dispositif pour économiser l'énergie lumineuse électrique comprenant des éléments électroniques associés au moins à une cellule photo-électrique qui permettent d'abaisser la lumière d'une lampe ou d'un groupe de lampes de façon à émettre une lumière à une intensité lumineuse inversement proportionnelle ou à peu près inversement proportionnelle à l'intensité lumineuse de l'environnement, l'intensité lumineuse minimale (figure 8) de la lampe ou du groupe de lampes pouvant être prédéterminée et préréglée en tout point de la caractéristique d'atténuation de la lampe, caractérisé en ce que la cellule photo-électrique est éclairée exclusivement par l'extrémité intérieure d'au moins un faisceau de fibres optiques (2) dont l'extrémité extérieure est placée à l'écart du dispositif afin de recevoir seulement la lumière de l'environnement et de la transmettre à la cellule photo-électrique.
2. Dispositif selon la revendication 1, caractérisé en ce que ledit groupe de lampes est joint dans un seul ensenble et est constitué par un chandelier (3, fig. 1) et que le dispositif est monté dans le circuit électrique du chandelier selon la structure pour la fixation du chandelier au plafond sous la rosace (4, fig. 1) dudit chandelier.
3. Dispositif selon la revendication 1, caractérisé en ce qu'il est adapté pour être capable d'être vissé entre le porte-lampe (9, fig. 6) et la lampe (10).
4. Dispositif selon la revendication 1 ou la revendication 2, caractérisé en ce que sur l'extrémité libre du faisceau de fibres optiques est monté un dispositif pour régler manuellement la lumière que le faisceau reçoit de l'espace environnant la lampe ou l'ensemble de lampes ou un connecteur pour fibres optiques (2', fig. 5) de façon que ce faisceau puisse être allongé pour le réglage manuel ou automatique à distance de l'intensité lumineuse désirée.
