Definitions

  • the present invention relates to a fluorescent tube lamp which can operate either on direct current or from the mains.
  • Fluorescent tube lamps operating on the mains are known, the fluorescent tube of which is supplied through an inductor limiting the current.
  • This self, called ballast is of a high weight and a large volume. Consequently, the fluorescent tube bulbs currently existing have dimensions greater than the normal dimensions of incandescent filament lamps and are of a significantly higher weight.
  • the object of the present invention is to produce a fluorescent tube lamp which overcomes the above drawbacks and which can have a range of light power corresponding to the light powers of filament lamps, while having equivalent weight and dimensions.
  • the fluorescent tube lamp comprises, in the enclosure formed by a hollow, cylindrical envelope, blind at one first end and closed at the other end by a base, a fluorescent tube forming a succession loops arranged along a polygonal contour, this fluorescent tube being mounted on an annular support and fixing plate of reflective material, said lamp further comprising a central reflector formed by a hollow cylinder whose base is an polygon with n sides , an electronic power supply and start-up circuit for the fluorescent tube.
  • a second object of the invention is to improve the efficiency of such a lamp.
  • the electronic circuit delivers, from a DC voltage supply, a current of frequency greater than the frequency of 50 hertz from the sector and having a form factor less than 1.7.
  • the central reflector is tightly mounted on a flange secured to the annular plate and comprises, at the end opposite to the annular plate, a pyramidal cap with a polygonal base, of which the polygon is angularly offset by , so as to have its sides parallel to the loops of the fluorescent tube adjacent to the first end.
  • a third object of the invention is to have a fluorescent tube lamp which can work in all applications.
  • This third object is achieved by the fact that, in the lamp, the DC voltage is obtained, either by an accumulator, or from the mains voltage, by a rectifier circuit integrated into the electronic circuit.
  • the polygonal contour of the loops of the fluorescent tube adjacent to the base is offset from the polygonal contour of the loops located near the first end of the enclosure by an angle .
  • the sides of the polygon of the base of the hollow cylinder of the central reflector are parallel to the polygonal contour of the loops of the fluorescent tube, adjacent to the base.
  • the polygonal contours are six or eight sides.
  • FIG. 1 represents a fluorescent tube lamp (5) according to the invention, having the normal dimensions of a filament lamp which are of the order of 70 mm in diameter and 180 mm in length.
  • This lamp comprises a base (1) provided with a thread (10) allowing, in known manner, its fixing in a socket.
  • a central connection stud (11) is connected by a wire (41) to a block (4) representing the electronic circuit making it possible, on the one hand, to perform the "starter” function for starting the lighting of the fluorescent tube, on the other hand, the "ballast” function for limiting the current during operation.
  • An insulator (12) makes it possible to electrically isolate the central stud (11) from the threaded part of the base to which the electronic circuit is connected by a second wire (40).
  • the wires (42) and (43) of the electronic circuit output (4) make it possible to supply, by the wire (43) a first end (52 f) of the fluorescent tube and by the wire (42) the second end (52 e) not visible from the fluorescent tube.
  • the fluorescent tube (5) describes, by forming loops, a circular path parallel to the annular edges (13) of the base (1).
  • On the external surface of the annular edge (13) is mounted, by any means known to those skilled in the art, a cylindrical hollow casing (20), blind at one end, so as to form a closed enclosure (2) with the nerve.
  • This hollow cylindrical envelope made of a material allowing the passage of light, is closed at its first end by a surface (21).
  • annular plate (3) On the internal surface of the annular rim (13) is mounted, by any means known to those skilled in the art, an annular plate (3), comprising a central orifice (31) provided a rim (30).
  • the annular plate (3) comprises, as can be seen in FIG. 1, an orifice (33) of dimension corresponding to the dimension of the fluorescent tube through which the end (52 f) of this tube passes which is connected by the conducting wire (43) to the electronic circuit (4).
  • the conductive wire (42) will be connected to the second end (52 e) of the tube which also passes through a hole (32) not shown and adjacent to the hole (33).
  • a reflector (6) is mounted on the edge of the plate (3) made of reflective material. This reflector (6) comprises, as can be seen in FIGS.
  • the cylindrical body (60) comprises, as can be seen in FIG. 2, a base whose vertices are coincident with the vertices of a hexagon and the sides connecting each vertex are constituted by arcs of a circle. This base will constitute what will be called subsequently a polygonal contour whose sides are (60 a) to (60 f).
  • the pyramid cap (61) also has a six-sided polygonal base (61 a) to (61 f) whose ends adjacent to the cylindrical body (60) form a curved surface which joins the vertices of the polygon forming the base of the cylinder.
  • the fluorescent tube (5) forms a succession of loops having a U-shaped section, so that two consecutive loops have their U-shaped section oriented in opposite directions. These loops are arranged parallel to the walls of the enclosure (2), of the reflector (6) and inside the hollow volume delimited by these walls.
  • a first loop is formed by the vertical portions (52 f, 52 fa) and by the portion (51 f) which is in the direction perpendicular to the portions (52 f, 52 fa) and parallel to the surface (21).
  • the next loop is constituted by the portions (52 fa, 52 a), which are in the direction parallel to the cylindrical sides (20) and (60 a) and by the central part (50 a), which is adjacent to the annular plate ( 3) and direction parallel thereto.
  • the loop having the central part the part (51 f) of the tube is in the opposite direction to the loop having the central part the part (50 a) of the tube.
  • the consecutive loop and direction identical to that having for central part the part (51 f) is constituted by the elements (52 a), (51a) and (52 ab).
  • the fluorescent tube is thus formed by a succession of loops, of the fluorescent tube, adjacent to the base (1) and of the plate (3) and a second succession of loops, of the fluorescent tube, adjacent to the first end (21) of the 'pregnant. These two sets of loops form a single continuous tube starting at the end (52 f) and ending at the end (52 e) that cannot be seen.
  • the loops (50 a, 50 b, 50 c, 50 d, 50 e), the loop (50 f) not existing because it is replaced by the connections (43) and (42), are arranged in a hexagonal outline , parallel to the hexagonal contour (60 a) to (60 e) of the cylinder (60) of the reflector (6).
  • the second series of loops comprising the central portions (51 f), (51 a), (51 e), loops which are located near the first end (21) of the enclosure, are arranged along a polygonal contour, parallel at the outline (61 a) to (61 f) constituting the base of the pyramid cap (61).
  • This arrangement allows in parallel to have the upper adjacent parts (51 a) and (51 b) arranged parallel to the faces (61 a) and (61 b) of the pyramid cap so that a radius (B), emerging from the face (51 a) of the tube, facing the pyramid cap, is reflected towards the outside of the enclosure closed by the surface (21). It will be the same for the radius (A) emitted by the face of the portion of the tube (51 b) turned towards the reflector (61 b). It will be noted that this arrangement of the elements makes it possible to release a hollow volume inside the cylindrical reflector (60).
  • This hollow volume communicates, through the orifice (31), with the part of the base (1) which contains the electronic circuit (4), which makes it possible, if necessary, to penetrate the electronic circuit (4) into this portion of volume hollow, if the need arises.
  • the electronic circuit (4) serving as "ballast", will operate at a frequency of the order of 20 to 25 KHz. This frequency, significantly higher than the sector frequency of 50 Hertz, clearly improves the light output of the fluorescent tube because of the better removal of electrons and cathodes by thermal agitation.
  • this electronic circuit (4) delivers to the electrodes of the ends of the fluorescent tube (5) a current having a form factor less than 1.7. We will recall that the form factor is equal to the ratio of the effective current on the peak current.
  • This electronic circuit (4) is intended to be supplied normally by a direct voltage of 12 or 24 volts which allows lamp applications for emergency lighting, for example.
