Definitions

  • Compact lamps also called energy-saving lamps, have been in high demand in recent years due to their low power consumption of only about a fifth compared to conventional incandescent lamps.
  • the object of the invention is to achieve the largest possible luminous area with a compact structure and economical effort.
  • 5 and 6 show a further improvement in that the interior of the filament is designed such that at least parts of the ballast can be accommodated in the center of the filament, which is either a shortened version of the lamp with the same power or a higher power with the same overall length allowed.
  • the gas discharge vessel of the compact lamp from an outer envelope (2), which corresponds approximately to the outer diameter of the compact lamp, and not, as previously, from a combination of thin tubes, the necessary electrode connections being arranged in this way are that they can be connected directly to the ballast, but releasably, in a simple manner to form a complete compact lamp.
  • the first of the two required electrodes on one side of the outer shell (2) and to provide the second electrode (5) on the opposite side of the outer shell, the connection (6) of which is led to the outside via a sealed, preferably centrally located inner tube (8), preferably in the direction of the connection (4) of the first electrode (3).
  • the diameter of the inner tube (8) is chosen according to the invention so that there is an optimal distance of a maximum of 12 mm between the inner tube (8) and the outer shell (2).
  • This ensures good properties of the gas discharge, but such a dimension also allows parts of the ballast (7) to be accommodated within the Inner tube (8) and enables cheaper lengths of the compact lamp.
  • the construction according to the invention also has a cost-saving effect if only the inside of the outer shell (2) is coated with an expensive fluorescent coating (9).
  • the inner tube (8) does not have to be provided with a fluorescent coating. Rather, it is recommended to provide the inner tube (8) with a well reflective coating, which increases the intensity of the irradiation of the fluorescent coating.
  • An electroconductive coating on the inside of the inner tube (8) can favor it by its electrostatic influence on the ignition process and represents a further possibility for improvement of the invention. Such an invisible application of a coating for ignition aid is not possible with previous designs.
  • the rotationally symmetrical shape of a gas discharge vessel according to the invention favors the arrangement of annular electrodes.
  • the electrode (3) can advantageously be implemented either as a wire ring, or as a coiled wire ring in the case of heated electrodes, or as a vapor-deposited conductive layer, which even allows simple heating in a known manner.
  • These segments can either be controlled cyclically in rapid succession by the ballast, or they can be switched together or in groups via electrical coupling elements (13). Both inductive and ohmic or capacitive connections can be used as the coupling element (13), which are simple and inexpensive to produce, particularly when the segments (11) are vapor-deposited to let.
  • a further measure according to the invention for homogenizing the discharge consists in providing a type of ionization chamber in the form of a cavity (14) at least on one electrode.
  • a type of ionization chamber in the form of a cavity (14) at least on one electrode.
  • heating of the electrodes is also readily possible, provided that the additionally required heating connections (15, 16) are provided.
  • additional ignition electrodes (17) are provided.
  • FIG. 5 shows the possible spatial reduction in the overall length of a compact lamp by allowing a part (22) of the ballast (7) to be immersed in the filament.
  • ballast (7) is firmly connected to the base (20) for insertion into a socket.
  • FIG. 7 shows the section through a compact lamp with a gas discharge vessel according to the invention.
  • the tightly sealed outer shell (2) can with the connections (4) and (6), which the two electrodes (3) and (5) with the Connect the ballast (7) and unplug it.
  • the connections (4) and (6) were drawn as simple plug connections, but any other type of connection as a bayonet connection or similar solutions are possible.
  • 8 shows the clear shape of the compact lamp from below.
  • the arrangement of the second electrode (5) at the lower end of the inner tube (8) is essential in order to achieve a uniform formation of the gas discharge.
  • the associated connection (6) is connected to the electrode (5) in the inner tube (8).
  • FIG. 9 shows a significantly improved example of a gas discharge vessel according to the invention.
  • the volume of the discharge space is reduced by a larger radius of the inner tube (8).
  • the distance between the inner tube (8) and outer shell (2) is reduced. The result is cheaper evacuation and filling with gas.
  • the inner tube (8) is provided with a coating (21) that can perform several tasks.
  • a coating (21) that can perform several tasks.
  • FIG. 9 The schematic in FIG. 9 as a vapor-deposited annular electrode (10) with its connections (12) has a direct connection to the ballast (7), which is also connected to the electrode (5) via the connection (6) stands.
  • the schematically represented cavity (14) in the area of the electrode (5) also favors gas discharge. It represents an ionization chamber that promotes a uniform function.
  • Fig. 10 shows a schematic circuit diagram of an annular electrode (10) which is divided into several segments (11). Each segment (11) has a connection (12) which is connected to the ballast (7).
  • the ballast (7) controls the individual segments cyclically in rapid succession, so that the areas of the gas discharge assigned to the segments (11) are acted upon without flickering.
  • Fig. 11 shows another variant of the control of the segments (11).
  • the segments (11) are connected by coupling elements (13) so that they can work independently of one another.
  • Fig. 12 also shows schematically that heating of the electrodes (3) or (5) is also easily possible. Only additional heating connections (15, 16) are required.
  • Additional ignition electrodes (17) are also possible in a known manner and are shown schematically in FIG. 12.
