Definitions

  • the invention relates to a lighting system according to the preamble of claim 1 , a tubular lamp intended to replace a fluorescent tube in a fluorescent tube armature according to the preamble of claim 2, and a device according to the preamble of claim 10.
  • Fluorescent tubes are based on the fact that a gas mixture of, for instance, argon and mercury vapour emits light at a satisfactory luminous efficiency when the gas is traversed by an electric current. Since this light substantially consists of UV radiation, the fluorescent tubes are coated on the inside with luminescent materials that react with the UV radiation. The fluorescent tubes have a considerable better luminous efficiency than conventional incandescent lamps, and their service life is longer than what is the case for the incandescent lamps, but finally, they still have to be replaced. This may involve an extensive operation, e.g., in public environments, where great amounts of fluorescent tubes are used.
  • LED light devices As an alternative to using fluorescent tubes, LED light devices have been developed.
  • An advantage of using LED light devices is that the light-emitting diodes (LEDs) have considerably lower energy consumption than corresponding fluorescent tubes, and therefore the power usage can be decreased from approximately 13W to approximately 3W.
  • the life time of a LED light device is normally considerably longer than the life time of a fluorescent tube.
  • a tubular LED light device intended to replace a previously present fluorescent tube in a fluorescent tube armature is known from WO2007/091972 A1.
  • the LED light device comprises at least one but preferably several LEDs connected in series to an electric circuit connecting at least one end connector arranged in one end of the tubular LED light device with at least one end connector arranged in the other end of the tubular LED light device.
  • an end connector in one of the ends is electrically connected to a phase wire via a conductor in one of the fluorescent tube sockets while an end connector in the other end of the LED light device is connected to a neutral wire via a conductor in the other fluorescent tube socket.
  • the fluorescent starter (sometimes also referred to as the glow switch, or simply the starter) should be either electrically disconnected or completely removed from the fluorescent starter socket in the fluorescent tube armature.
  • LED light devices similar to the one described above are also known from co-pending patent applications SE 0950075-2 and SE 0950074-5.
  • a problem related to these types of LED light devices is that the end connectors in the opposite ends of the device are electrically connected to each other via the electric circuit to which the LEDs are connected.
  • fluorescent tubes do not conduct current before a high voltage has been applied between the end connectors in opposite ends of the tube, LED light devices intended to replace fluorescent tubes in fluorescent tube armatures do.
  • WO2009/087074 A1 addresses this problem by presenting a rod-shaped lamp, such as a rod-shaped LED hght device, comprising at least one power switch which is brought to close an electric circuit including light-emitting members, such as LEDs, when the two ends of the lamp are simultaneously inserted into a respective contact socket of a light fitting, such a fluorescent tube armature.
  • the power switch comprises one or several switching members which may consist of one or more pressing members projecting from the lamp. The pressing members are displaceable into the lamp and are arranged to close the electric circuit including the light-emitting members when displaced into the lamp.
  • the pressing members may be arranged on at least one switching body, which is arranged to be displaced into the lamp when the pressing members are brought into contact with the respective contact socket or sockets.
  • the switching body may support at least one guide pin, which is arranged to run into at least one guiding groove when the two ends of the lamp are simultaneously inserted into a respective contact socket.
  • the inward motion of the guide pin may be arranged to be stopped by at least one guide head if one of the ends of the lamp is inserted into a contact socket before the other.

Abstract

La présente invention porte sur un système d'éclairage (10), qui comprend une armature de tube fluorescent (1), une lampe tubulaire (27), telle qu'un dispositif d'éclairage à diodes électroluminescentes, conçue pour remplacer un tube fluorescent (3) précédemment présent dans l'armature, et un dispositif (30) conçu pour remplacer un starter de fluorescence (14) précédemment présent dans une douille de starter de fluorescence (15) de l'armature. La lampe tubulaire est conçue pour être alimentée en courant à partir d'une seule extrémité, et le dispositif de remplacement de starter de fluorescence (30) adapte l'armature au fonctionnement avec une telle lampe alimentée d'un seul côté. Le système d'éclairage proposé (10) élimine, ou, tout au moins, réduit, le risque d'être soumis à des chocs électriques lors du remplacement de tubes fluorescents par des lampes tubulaires dans des armatures de tube fluorescent existantes.
