Definitions

  • the present invention relates to a lighting lamp comprising at least one low-pressure discharge tube, a standardized base intended to be screwed or inserted into a socket connected to an electrical distribution network, an electronic circuit transforming the low frequency of the high frequency distribution network to supply the tube and an intermediate element disposed between the tube and the base.
  • Fluorescent tubes have therefore been proposed with a standard base or base, for example of the screw or bayonet type, which can be plugged directly into a standard socket. As such a tube cannot be connected directly to the network, if only because of the high voltage necessary to create the ignition of the arc in the lamp, as well as because of the need to limit the current in the tube once this ignition has been carried out, the low-pressure lamps on the market are much more bulky and much heavier than the incandescent lamps that they are supposed to replace.
  • the lamp 1 shown in FIG. 1 comprises a fluorescent tube 2 and a base 3, tube and base being joined by an intermediate element 4.
  • the tube is conventional, of the type described for example in document GB-A-2 050 046.
  • the intermediate element 4 in addition to being used to mechanically connect the tube to the base, contains an electronic circuit to increase the supply frequency, as well as a ballast and a choke to limit the current in the tube and to create striking the arc, respectively.
  • the intermediate element also contains a radio frequency deworming device.
  • This deworming device mainly comprises a double choke coupled by a ferromagnetic core arranged in series in the power supply of the electronic circuit.
  • This double inductor without reaching the weight and size of the ballast used for a direct supply on the network, however takes a relatively large place, which requires an intermediate element 4 of relatively large diameter, in any case of a double diameter of that presented by the base.
  • the lighting lamp according to the invention in addition to implementing an electronic circuit transforming the low frequency of the distribution network into high frequency, is characterized by the fact that the electronic circuit is entirely confined inside the standardized base, while the current limiting element is housed with the choke in an intermediate element.
  • FIGS 2, 3 and 4 are general views of the discharge lamp according to the invention.
  • This lamp 5 comprises a low pressure discharge tube comprising two branches 6 and 7 connected by an isthmus 8.
  • This tube produced for example according to the document GB-A-2 050 046 already cited, contains, as is known, mercury vapor at low pressure and its inner wall is coated with fluorescent substance.
  • the lower parts of the branches 6 and 7 are introduced into an intermediate element 9 where they are sealed.
  • This base is intended to be screwed into a socket also standardized, socket connected to an electrical distribution network delivering for example 220 VAC / 50 Hz.
  • the lamp 5 as described also includes an electronic circuit transforming the low frequency of the distribution network into high frequency to supply the tube. According to the invention, this electronic circuit is entirely confined inside the standardized base 10.
  • Figures 2 and 3 show that the intermediate element 9 has a cylindrical shape whose outside diameter and height are substantially equal to the diameter and the height of the base 10.
  • FIG. 5 which is a partial view of the lamp according to the invention, shows that said invention is not limited to the use of an E27 screw base.
  • a base 13 of the bayonet type B22d comprising a smooth metal coat 14 provided with two lugs 15 and a central electrode 16.
  • This base 13 is subject to an intermediate element 9 similar to that which has been described more top, said element carrying a tube not shown.
  • FIG. 6 shows, on an enlarged scale, the interior of the lower part of the lamp 5.
  • This figure shows the branches 6 and 7 of the discharge tube, the intermediate element 9 and the base 10.
  • the figure shows that the end 17 of branch 6 of the discharge tube is sealed with a cement 18 inside the intermediate element 9. It is the same for the end of the branch 7 which does not appear in the drawing.
  • the end 17 is closed by a pinch 19 and comprises a filament 20 forming one of the electrodes of the tube.
  • the filament is carried by wires 21 and 22 which pass through the glass of the tube.
  • Another filament is disposed in the same way at the end of the branch 7 and the leads of this other filament are referenced by 23 and 24.
  • the intermediate element 9 also has an inner annular groove 25 in which is housed the flared rim 26 presented by the base 10.
  • Intermediate element 9 and base 10 are immobilized relative to one another by means of an adhesive or a cement 27 which is placed in the groove 25.
  • Figures 2, 3 and 6 show that the lamp is formed from a tube with two branches 6 and 7.
  • the aesthetics of the lamp can be improved by breaking the cylindrical shape of the intermediate element by two sections inclined 28 and 29 which open in the form of a roof in the direction of the base 10. This way of considerably reducing the general shape of the lamp.
  • the panels 28 and 29 allow a better grip of the lamp, when it is a question of introducing it into its support socket.
  • the intermediate element (which is preferably made of insulating material, for example ceramic) contains a current limiting element L and a choke C7.
  • the choke C7 is connected between the outputs 22 and 23 of the tube and is located between the nips of the branches 6 and 7.
  • the limiting element L is located in front of the figure and is connected in series between the output 21 of the branch 7 and a point 29 of a printed circuit 30 which will be described below.
  • the output 24 of the tube 7 is connected to a point 31 of the same printed circuit.
  • the electronic circuit In the base 10 of the lamp takes place, according to an essential characteristic of the invention, the electronic circuit, generally designated by 32.
  • the main task of this electronic circuit is to transform the low frequency of the network (50 or 60 Hz) into high frequency of discharge tube supply.
  • FIG. 6 clearly shows that this circuit 32 is entirely confined in the standardized base 10 (here of the Edison E27 type).
  • the electronic circuit 32 comprises a printed circuit 30 having the shape of a disc (see also FIG. 8) whose diameter is substantially smaller than the internal diameter of the base 10.
  • On this disc are mounted vertically electronic components, such as the transistor T1, the diode D6, the resistor R4 and the capacitors C2 and C4, which alone appear in FIG. 6 and which form part of the overall diagram illustrated in FIG. 7.
  • the electronic circuit 32 is connected to the supply network by line 33 which is welded to the electrode 12 of the base 10 and by the line 34 which is welded to the mantle 11 of the same base 10.
  • FIG. 8 shows in detail how the electronic circuit 32 is organized.
  • This circuit includes a printed circuit 30, as has already been said above.
  • the electronic components are all located, except for one, on one side of the printed circuit and, in FIG. 8, face the observer.
  • T designates the transistors with their terminals BCE, D the diodes, DR an inductance, C the capacitors and R the resistors.
  • the printed circuit 30 has conductors on its two faces. In FIG. 8, only the conductors printed on the opposite face appear in dashed lines (references 35) so as not to make the drawing heavy. In the center of the figure is the resistor R1.
  • the wire which emerges therefrom, bearing the reference 33, on the observer side, is directly connected to the electrode 12 of the base, as already presented in FIG. 6.
  • the wire 34 which connects the printed circuit to the mantle of the base , wire which is shown in FIG. 6.
  • the outputs of the components which have connection wires situated on the printed circuit side pass directly through openings situated through the disc 30. This is the case for example of the transistors T1 and T2 and of the capacitors C2, C3 and C4.
  • resistors R2, R3, etc. and diodes D1, D2, etc. all have a connection wire which is folded along the component before being soldered to the printed circuit. This is the case, for example, of the diode D6 and the resistor R4 which each have a wire referenced 37 and 38 respectively.
  • the conductors printed on the disc 30 have metal points pierced with openings into which the conductors of the various electronic components come soldered. It's the case for take an example, metal points 39 and 40 respectively receiving the components R8 and D4, these points being pierced by the openings 41 and 42 respectively. According to an embodiment of the present invention, it can be seen that the holes 41 and 42 are not made in the center of the metal points 39 and 40, but are moved relative to the centers of these points, this for the purpose of '' avoid short circuits between neighboring welds. Figure 8 shows still other places where such an arrangement is implemented. Thus, when the components are welded, by hand or by wave, there will be no welding bridges between the points which must remain isolated from each other.
  • FIG. 7 is an electronic diagram of the circuit corresponding to the layout illustrated in FIG. 8.
  • the electronic circuit 32 is entirely confined within the base 10, represented in FIG. 7 by a frame in dashed lines.
  • Terminals 11 and 12 respectively represent the metal mantle and the central electrode of the base.
  • Points 29 and 31 show the connection terminals for the outputs of the electronic circuit, outputs which are connected to the intermediate element 9 (also shown in FIG. 7, by a dashed line frame) in which there is the current limiting element.
  • L, choke C7 and the ends of the discharge tube From the intermediate element 9 emerges said tube with its branches 6 and 7.
  • the circuit generally comprises an oscillator comprising two transistors T1 and T2 reactively coupled by an element composed of three coils LR1A, LR1B and LR1C wound around a common core.
  • This element is represented in FIG. 6 by the reference LR and is housed on the welding side of the disc 30. It is therefore not represented in FIG. 8, except by a certain number of its connection points referenced 43 to which the inputs and outputs terminate. coils which can be wound on a ferrite core.
  • the oscillator therefore known per se, delivers a frequency generally between 30 and 40 kHz and feeds the discharge tube. Its operation will therefore not be described in detail here.
  • the oscillator is supplied with direct current by a Graetz bridge formed by diodes D1 to D4.
  • the Graetz bridge supplying the lamp according to the invention is connected to the network by means of a resistor R1, R2 arranged in series between each of the inputs 44 and 45 of said bridge and of the inputs 12, 11 of said network, a capacitor C1 being arranged in parallel on the lines of the network.
  • the resistors R1 and R2 have a value of 15 ⁇ and the capacitor C1, a value of 33 nF.
  • the Graetz bridge supplying the lamp according to the invention is followed by a ⁇ filter comprising an inductance DR in its horizontal branch (typically 820 ⁇ H) and a capacitor (C2, C3 + C4) in each of its vertical branches (typically 2.2 ⁇ F and 2.2 + 2.2 ⁇ F). Thanks to this filter, the parasitic components are rejected below the level admissible by international standards (in particular the German standards VDE 0875, part 2) in the radio frequency band extending from 0.01 to 30 MHz. This latter arrangement also makes it possible to dispense with the heavy deworming device which was mentioned above with regard to the Osram DULUX EL lamp. It also makes it possible to use capacitors C2 to C4 of smaller diameter instead of just one larger, as is the case in the prior art.
  • the lamp comprises a tube with two branches 6, 7.
  • the invention is not limited to these two branches, the tube possibly comprising four, for example. In this case, it will be possible, at equal brightness, to decrease the overall length of the lamp and thus approach the length of an incandescent lamp.
  • the intermediate element 9 would then have an essentially cylindrical appearance, without inclined faces, as has been described above.
