Definitions

  • Lighting device with a discharge lamp and a partially arranged externally to the discharge lamp and electrically connected to this electronic control gear
  • the invention relates to a lighting device with a discharge lamp and an electronic control device for the discharge lamp.
  • lamps which have a helical or helical discharge vessel. These are currently known mainly as so-called CFLi (Compact Fluorescent Lamp with integrated bailast), which means that an electronic operating device for the discharge lamp is integrally arranged in it.
  • CFLi Compact Fluorescent Lamp with integrated bailast
  • the contacting of the four protruding from the lamp ends wire ends usually takes place via a spring contact or by twisting with pins on the board.
  • the connection to the mains voltage takes place via a standardized base.
  • CFLni Compact Fluorescent Lamps with non integrated bailast
  • ie discharge lamps in which the electronic control gear is completely ex- is arranged, known.
  • Such lamps offer a significant advantage in terms of the requirement of a compact design, but they require the formation of four contact elements on the lamp base.
  • a luminaire device comprises a discharge lamp and an electronic operating device which is partly arranged externally to the discharge lamp and which is provided for operation for the discharge lamp.
  • the operating device comprises a circuit arrangement having a plurality of electronic components, wherein at least one circuit part of the circuit arrangement is arranged externally to the operating device and is arranged in the discharge lamp.
  • the lighting device is thus designed such that the operating device as a whole is not functionally and component-technically completely separated from the discharge lamp and is not formed completely integrated into the discharge lamp.
  • the operating device has a circuit arrangement with a plurality of electronic Having components, wherein at least a first circuit part of the circuit arrangement is arranged externally to the discharge lamp and a second circuit part of the circuit arrangement in the discharge lamp.
  • CFLni lamps can be realized, which can be constructed compactly and thus also ensure use in so-called consumer luminaires.
  • the spatial separation of the discharge lamp from circuit parts of the operating device through the product development of temperature-sensitive integrated circuits (IC) facilitates the use of these and reduces the requirement for the compactness of the operating device, as is advantageous, for example, with dimmable lamps ,
  • the second circuit part is connected in circuit parallel to the discharge lamp. It is this special feature that enables special functionalities of the operating device with the required components to be integrated into the discharge lamp.
  • the second circuit part is arranged in a base of the discharge lamp. Again, thus a compact design can be guaranteed, as a anyway existing socket can be used to accommodate this second circuit part.
  • the second circuit part has a resonant capacitor as an electronic component, in particular only the resonant capacitor, which is designed to ignite the discharge lamp and contributes to the preheating.
  • a particularly compact implementation can be made possible, since only a single component, which is normally assigned to the external operating device, is separated and integrated into the discharge lamp.
  • the remaining components of the usually constructed operating device are arranged externally of the discharge lamp.
  • the simplest way to form a cold-start lamp is to be implemented. In accordance with more complex design of the operating device and a warm start lamp can be formed.

  • a "middle-volt version" can be realized in which voltages between 100 V and 120 V are present.
  • the discharge lamp has two electrical contact pins, which extend outward from the base.
  • the discharge lamp has only two electrical contact pins. In comparison to conventional discharge lamps of the same design, which imperatively require four electrical contact pins, this makes possible a substantial reduction of these contact pins. This can be ensured precisely by specific removal of specific circuit parts from the operating device and integration into the discharge lamp.
  • the base of the discharge lamp has a height of less than 4 cm, in particular less than or equal to 3.5 cm. In particular, it is provided that the height of the base measured from the lower part of the discharge vessel is less than or equal to 2.5 cm.
  • the base of the discharge lamp can be made extremely compact, which also in view of the compact design of the entire lamp is advantageous. It is particularly preferred if the socket is a G28d socket.
  • the lighting device has a socket for receiving a base of the discharge lamp, which has a height of less than 2.5 cm, in particular less than or equal to 2 cm.
  • the overall system of discharge lamp and socket can be made very compact. It proves to be particularly preferred if the socket is also designed according to the G28d standard.
  • the socket and the base of the discharge lamp have mechanical codes. These may be, for example, pins, webs, scenes and correspondingly complementary elements. Such a coding can be achieved that only technically matched to each series series are combined, which is advantageous in terms of operating functionality.

The operating behavior can thus be coordinated at any time and optimized in terms of function.
  • a discharge vessel of the discharge lamp is at least partially helical.
  • the socket for receiving a base of the discharge lamp is also designed as a G28d socket.
  • the mechanical connection between the socket and the base of the discharge lamp is designed as a bayonet connection.
