Definitions

  • the present invention relates to a device applicable to gas discharge tube lamps, which makes it possible to reduce active energy consumption by 40% without modifying the luminous flux of the tube on which it is mounted, and which, in addition , reduces environmental contamination by ultraviolet radiation.
  • ultraviolet rays electromagnetic radiation which has a wavelength between 100 and 400 nm (nanometers).
  • UV-A rays are invisible and fall into three bands: long waves, called UV-A rays, from 315 to 400 nm, medium waves, UV-B rays, from 280 to 315 nm and short waves, UV-C rays, from 100 to 280 nm.
  • the radiation from the UV-A band passes through almost all types of glass and practically does not cause erythema (redness of human skin). It has the property of causing the fluorescence of certain materials and of causing photochemical reactions, among others.
  • the radiation from the UV-B band causes erythema and pigmentation (tanning) effects on the skin. These radiations are used mainly for therapeutic purposes (solar lamps).
  • the radiation from the UV-C band which has its maximum efficiency around 254 nm in wavelength, can give rise to fluorescence phenomena in certain materials and cause erythema and conjunctivitis.
  • the bands “A” and “B” pass through almost all types of glass and the short band, or "C”, is the one that excites and produces the greatest photonic effect on phosphorus, causing the emission of light photons.
  • the point of greatest photon production is more specifically at the 253.7 nm wavelength; this is the effect you get in the ionized cavity tubes by electronic bombardment.
  • the tube manufacturers have made various attempts to increase the brightness of these tubes and, for this, they provide the tubes with a reflective layer placed inside the glass of this tube, but without thereby obtaining a significant increase in the luminous flux, nor any additional advantage.
  • DE-C-838 796 discloses a fluorescent tube which has a reflective surface in silver, mercury or amalgam on part of its glass wall.
  • the aim of the present invention is therefore to achieve better exploitation of ultraviolet radiation in fluorescent tubes so as to obtain an increase in the luminous flux of this radiation, and to achieve a considerable reduction in the energy consumption for a luminous flux equivalent to the original flow indicated in the catalog.
  • DE-A-2 410 037 relates to a device in accordance with the preamble of claim 1.
  • the invention achieves its object by the characteristics described in the characterizing part of claim 1.
  • the phosphor and glass envelopes produce a 90% attenuation of the light passing through them, and it is therefore the ultraviolet rays in the large and medium bands (A + B) which, once again crossing the envelopes, produce excess luminous flux.
  • FIGS. 1 and 2 show a fluorescent tube 1, the upper half-cylinder 3 of which has been covered with a lampshade 5, the reflecting surface of which is in contact with the external surface of the glass of this half-cylinder 3, the half lower cylinder 2 remaining as light emitting surface.
  • This lampshade 5 is preferably formed of treated aluminum, alone, or of aluminum plus a plaster reticle, which may also be of aluminum varnish, alone or supplemented with a plaster reticle, with plastic. aluminized and / or screen printing of plaster, etc.
  • This lampshade 5 which allows the photonic irradiation process of phosphorus to be fully realized under the effect of UV rays (medium and low waves) which escaped through the thin layer of phosphates and which passed through the glass of the upper half-cylinder 3 and are returned towards the inside of the tube 1 by the reflecting surface of the lampshade 5.
  • the "window" or the lower half-cylinder 2 which results from the presence of the external lampshade 5, which is printed or glued to the tube 1 and covers the most adequate percentage of dimensions (relative to the perimeter of the tube), makes it possible to obtain a light concentration in the window, or in the lower half-cylinder 2, which responds to high efficiency curves (UV-light conversion).
  • UV-light conversion high efficiency curves
  • Said step-down element can be constituted by a resistant element integrated into the lampshade 5 and which is preferably constituted by a printed resistance made of metal or a resistant material of the type of baked semiconductor resins, and glued to the glass on its outer wall, on the aluminum sheet, on plastic or rigid bases of the alumina type, possibly with a flat capacitor which can be glued to said lampshade 5 or glued to the support element 7 It can also be composed, among other things, of a self-transformer or a resistive element and a capacitor connected in series, or it can include a capacitor associated with a timer connected to a connected triac and a coil. serial.
  • This step-down element is connected to the terminals 4 of the fluorescent tube 1, using connection means which are preferably composed of insulated conductors, not shown.
  • the tubes can be lit without the need for the reactance usually used for this.
  • a second preferred embodiment of the invention which is shown in FIGS. 3 and 4, is that in which the reflecting lampshade 5 ′ is provided on its inner surface with a support element 7 whose diameter coincides with the diameter of the tube 1, and is further provided with fins 6 which direct the light flux which exits through the half-cylinder 2.
  • said lampshade 5 ' is incorporated any one of the abovementioned voltage-reducing elements, which is connected to the terminals 4 of the tube by means of connection means not shown.
  • This 5 'lampshade can be easily applied to already existing domestic installations.
  • An additional advantage which is obtained by working under low voltage, that is to say around 170 V, consists in that the tube works at temperature regimes between 25 and 30 ° C., in an ambient temperature of 23 ° C. Working at these temperatures lengthens the useful life of the tube and is very advantageous for obtaining better lighting, since it is the ideal temperature range indicated by the manufacturers for the production of UV in the tubes.
