  • the lead wires 118a, 118b, 118c, etc. extend at a right angle away from the surface of the dish portion of the connection portion 109 with the first coil 117a and the second coil 117b respectively disposed at the ends thereof, and thus in the region is arranged with a smaller diameter of the connecting portion 109.
  • the coils 117a and 117b are therefore also in contact with the neon gas in which the gas discharge is to be ignited and maintained.
  • the neon gas is located substantially in the interior or gas discharge space 115 of the outer tube 102 except for the volume, which is displaced by the closed with the left 108 and right 109 connecting portion inner tube 107 as a dead volume.
  • the neon gas in the annular gas discharge space 115 between the outer tube 102 and the inner tube 107 is present, and in each case in the region of the outer tube 102, where the right and left connection region 108 and 109 is arranged and where also the coil 117a and 117b is present for igniting and maintaining the gas discharge.

  • the inside 122 of the outer tube 102 is provided with a coating 123 which filters a certain portion of the light wave spectrum generated by the neon gas in the gas discharge.
  • the photons emitted by the gas discharge are reflected by the facets 114 on the outer side of the inner bulb 107, the concave configuration of the facets 114 extending in the longitudinal direction of the fluorescent lamp 101 reflecting the photons in an even distribution and thus uniform emission of the fluorescent lamp 101.
  • the arrangement of the inner piston 107 in the interior of the outer tube 102 also reduces the gas volume in this embodiment compared to conventional fluorescent lamps in which no inner piston is present in the interior. As a result, a smaller amount of gas for the gas discharge is necessary, with the same outer diameter of the fluorescent lamp. Due to the reflective and faceted surface of the inner bulb, the light emission of the

  • gas discharge lamps having two lamp sockets have been described. In other embodiments, however, only one lamp cap is present.
  • gases and phosphor coatings are also given by way of example only. As already mentioned, in other embodiments, other gases that are known to be used to generate light in gas discharge lamps are used.

Abstract

L'invention concerne une lampe à décharge comprenant : un tube extérieur (2 ; 102) ; un cylindre intérieur (7 ; 107), le cylindre intérieur (7; 107) étant placé à l'intérieur du tube extérieur (2 ; 102), de sorte qu'un espace de décharge (15 ; 115) est formé entre le tube extérieur (2 ; 102) et le cylindre intérieur (7 ; 107) ; et un gaz qui, lorsqu'un courant électrique est appliqué, produit une lumière à partir d'une décharge électrique dans le gaz, le gaz étant introduit dans l'espace de décharge (15 ; 115) de sorte que la décharge se produit dans cet espace de décharge (15, 115).
