Definitions

  • the invention relates to an emergency light element for operating fluorescent lamps according to the preamble of claim 1.
  • Emergency lighting elements for fluorescent lamps serve the purpose that the fluorescent lamp can automatically continue to shine in a kind of emergency operation in the event of an interruption or a fault in the AC voltage.
  • a lamp ballast is known from DE-OS 29.05.598, which converts the mains alternating current into direct current for operating the lamps by means of direct current.
  • the task of this lamp ballast is to avoid alternating fields. It is not possible to operate fluorescent lamps with this lamp ballast.
  • a circuit arrangement for emergency lights in which two circuits, a direct current circuit and an alternating current circuit are formed with a common feed, in which a diode is in the forward direction in the emergency circuit.
  • the power lamp which can be a fluorescent lamp
  • an emergency light is provided. With AC mains voltage, the diode always flows the positive half-wave - the negative half-wave is blocked - of the AC mains current through the emergency light, which lights up in addition to the mains light.

  • an emergency lighting system in which only the power lamp is provided, which can be a fluorescent lamp that is fed indirectly by a rechargeable battery voltage source in the event of a power failure or malfunction.
  • an AC-DC converter is provided, the DC output voltage for operating the power lamp is converted into an AC voltage via a DC-AC converter in the form of a reversing circuit.
  • An analog ballast is provided, which essentially contains an ignition transformer for starting and for operating the fluorescent lamp on the AC voltage network. The ballast cannot be operated on direct voltage, and the power of the fluorescent lamp cannot be programmed via the ballast for reduced light requirements, which is why the direct voltage / alternating voltage converter is necessary.
  • the emergency lighting system can be plugged onto a standardized shortened fluorescent lamp and can therefore be placed in the holder for the usual longer standardized fluorescent lamps be plugged in. Additional wiring is not necessary. It is disadvantageous that the power requirement of the fluorescent lamp cannot be adapted to the battery voltage source in the event of a power failure or malfunction.
  • Digitized electronic ballasts for fluorescent lamps have been on the market since the beginning of 1998, and can process both DC and AC voltage at their input. When DC voltage is present, the luminous flux and the current consumption of the fluorescent lamp are automatically reduced. The value of the luminous flux or the current consumption can be programmed in the digital electronic ballast.
  • the fluorescent lamp can be located in a bridge branch of a switching bridge with four switches, two of which are always closed diametrically arranged switches and the other two switches are open.
  • the switches are controlled by a control circuit, and a switching regulator controls a switching element, via which the switching frequency and thus the power output can be specified, or the pulse duty factor for power adjustment is changed on the switching regulator.
  • a 'half-bridge may be used with two switching elements, wherein the tube between the center of the bridge and is OV or between the center and rectified, smoothed network voltage.
  • the present invention is therefore based on the object of specifying an emergency lighting element which can be easily adapted to existing fluorescent lamps with digital electronic ballasts without being rewired and is self-sufficient in the event of network interruptions or faults and which provides sufficient energy for operating the fluorescent lamp in an emergency over periods of several hours.
  • the emergency light element according to the invention has the advantage that it can be easily attached with plug-in feeders and can be accommodated in a hollow ceiling or in a subdistribution. If the emergency power supply is disconnected from the luminaire as an emergency lighting element for maintenance purposes, the plug connections can be made are brought together and the fluorescent lamp 'continues to burn as a normal power lamp. So no rewiring is necessary because the simplest plug connections are sufficient.

  • Fig. 2 the emergency light element in the switch position mains operation.
  • Fig. 1 shows the emergency light element NLE in the switch position emergency operation.
  • UN is the AC mains voltage that charges the rechargeable battery voltage source Ubatt via the AC / DC converter.
  • the AC / DC converter can be configured as a half-wave rectifier by means of a diode with a capacitor of appropriate capacity and a constant voltage regulator. Such circuits are commercially available as integrated modules.
  • the DC-DC converter can also Constant voltage regulator can be realized; the output voltage 'then adapts to the battery voltage and the residual voltage drop across a series resistor.
  • the fluorescent lamp LA is preceded by the digital electronic ballast EVG, which ignites the fluorescent lamp LA and which can process both AC and DC voltage at its input 9, 10.
  • the ECG is controlled via the bus with digital information.
  • the output voltage of the ECG, which is applied to the tube, is - due to the fluorescent lamp - always a high-frequency high voltage.

  • the DC-DC converter DC1 / DC2 can consist of a chopper amplifier in which DC voltage is "chopped" at the input into an alternating signal. This AC voltage is amplified and then rectified again.

Abstract

L'invention concerne un élément lumineux de secours (NLE) utilisé pour actionner des lampes fluorescentes (LA) en cas de panne de secteur, au moyen d'une source de tension de batterie (Ubatt) pouvant être alimentée en tension alternative du réseau (UN). Un régulateur de puissance de wattage électronique numérique (EVG) monté en amont de la lampe fluorescente (LA) allume la lampe fluorescente (LA) et peut traiter à son entrée, aussi bien une tension alternative qu'une tension continue. Selon l'invention, l'élément lumineux de secours est monté en amont du régulateur de puissance de wattage électronique numérique (EVG) et dans ledit élément lumineux de secours (NLE) la tension continue de la source de tension de batterie (Ubatt) qui peut être chargée, est convertie par l'intermédiaire d'un convertisseur continu-continu (DC1/DC2) en une tension continue (DC2) plus élevée. Une unité de surveillance du réseau actionne des contacts de commutation (S1,S2) de manière qu'en cas de tension alternative de réseau, la sortie du régulateur de puissance de wattage électronique numérique (EVG) soit pilotée par la tension alternative de réseau (UN) et qu'en cas de panne de secteur, l'élément lumineux de secours (NLE) fournisse la tension continue au régulateur de puissance de wattage électronique numérique (EVG).
