Definitions

  • This invention relates to a lamp with integrated electronic ballast (ECG) and to an electronic ballast as such, in which the electromagnetic compatibility (EMC) is improved.
  • the invention is based on the technical problem of specifying a luminaire with integrated electronic ballast and an electronic ballast which show an improved electromagnetic compatibility with respect to such resonance phenomena in the high-frequency range.
  • a luminaire with integrated electronic ballast characterized by a damping element High frequency radiation absorbing material designed to attenuate high frequency radiation absorption in a line of the luminaire between a PE terminal of the luminaire and a ground terminal in the luminaire by high frequency radiation absorption,
  • an electronic ballast for a lamp characterized by a corresponding damping element which is adapted to attenuate high-frequency currents in a line of the ballast between a PE terminal of the ballast and a ground terminal in the ballast.
  • the term “luminaire” here does not refer to a luminous means as such, that is to say the consumables responsible for the actual generation of light, but to an illuminating device with or for receiving a luminous means, ie a lamp ,
  • a lamp thus has a housing and often a screen, a reflector, translucent cover glasses u. ⁇ . on.
  • the basic idea of the invention is to provide a damping element in the luminaire or in the ballast which generates high-frequency radiation losses in the frequency range of interest by material-specific high-frequency damping properties and thus dampens and reduces the amplitude of disturbing resonance phenomena.
  • materials with suitable magnetic properties that can be attenuated by magnetic HF losses are suitable. This is especially true for ferromagnetic ceramic materials, especially of iron oxide, which are also known as Dämpfungsferrite.
  • damping element should preferably not be integrated into the conductor itself - the ferrites would also be due to the conductivity missing - but only be mounted near the head.
  • the damping element surrounds the conductor by being a body with a passage opening.
  • Particularly suitable are so-called pearls, ie small spheroidal bodies with a bore, rings or small tubes.
  • the line to be damped is in the case of the claimed ballast between the PE terminal of the ballast and the ground contact on the ballast housing or a corresponding part thereof.
  • the line currents participating in the resonance phenomena must run through this line.
  • the overall PE terminal of the luminaire differs frequently from the PE terminal of the ballast integrated in the luminaire, or the ballast may not have its own PE terminal.
  • the attenuated by the damping element line here is between the PE terminal of the lamp and the ground contact one for the resonance phenomena with responsible luminaire housing part or the lamp housing as a whole. Capacities which are (partially) linked to the luminaire housing and participate in the resonance phenomena then cause damped currents through this line.
  • a conductive housing of the integrated ballast can be involved in significant capacities, so that it is also preferred that the line between the PE terminal of the lamp and the ground contact of the ballast housing is located.
  • the ballast ground contact can be made to the lamp housing (part), so that even by a damping of the line between the PE terminal of the lamp and the ground contact on the lamp housing (part) and the currents are included to the ballast housing.
  • the damping element in the terminal. If so far it has been said that the damping element should attenuate a line between the PE terminal and a certain ground contact, the term “between” means the area from the actual terminal contact for the external line.
  • the damping element is to be integrated in the terminal body, so for example in a conventional luster terminal in the vicinity of the conductive piece between the terminal connection for the external line and the internal terminal contact, in particular a form enclosing this conductive piece.
  • integrated in here means that the damping element in the component including its insulating holder should be included or held so that it can be mounted together with and in the terminal by the lighting manufacturer or ballast manufacturer and may even be already purchased ,
  • Figure 1-3 show three circuit arrangements according to the invention with a lamp terminal with integrated damping element.
  • FIG. 4 shows an interference spectrum of a luminaire with an electronic ballast without attenuation of the high-frequency interference.
  • FIG. 5 shows an interference spectrum of a luminaire with an electronic ballast and with a luminaire connection terminal according to the invention with an integrated damping element in the circuit according to FIG. 1.
  • FIG. 1 shows a circuit arrangement according to the invention with a lamp terminal LK with integrated damping element F for a Luminaire with electronic ballast electronic ballast.
  • the damping element F is a high-frequency-absorbing ferrite bead and integrated in the luminaire terminal itself. It lies on the conductive connection between the terminal connection contact for the external PE supply line on the one hand and an internal line leading to the luminaire housing.
  • the line piece with the damping element F is thus connected between the lamp housing and the ground conductor PE, in which case the electronic ballast ECG via the lamp housing (or a line) and finally the damping element is connected to the ground conductor PE.
  • the damping element F absorbs the noise spectrum resulting from the resonant vibrations of the lamp housing and the housing of the electronic ballast, in particular from the capacitive couplings between the lamp housing and the environment, and attenuated in this way the high-frequency interference.
  • FIG 2 shows a modification of the circuit arrangement according to Figure 1.
  • the ferrite bead is also integrated in the lamp terminal, but only set to a PE connection cable with which the ballast ECG is connected via the lamp terminal to the external PE line.
  • the housing of the lamp is either, as drawn, independently connected to the external PE supply line or could be configured in this embodiment, even without ground contact, for example in the case of a plastic light. So here the capacitive influence of the lamp housing does not play a decisive role and is not considered in the damping according to the invention.
  • the ferrite bead F which is likewise integrated into the lamp connection terminal, only affects a conductive bridge to the line to the earth contact of the luminaire housing. Since the ballast EVG is here in contrast to the variant of Figure 1 via a supply line to the lamp terminal connected to the external PE line and this lead is not detected by the ferrite bead is, the capacitive influence of the ECG housing is not taken into account here. It can be insignificant in individual cases. Deviating from the figure, it could also have been dispensed with due to the grounding of the lamp housing on a conductive and grounded ECG housing. Of course, it would also be possible for a second or a common ferrite bead to be present for both housing ground supply lines.
  • Figure 4 shows an interference spectrum (in dB ⁇ V at 50 ⁇ ) a lamp with electronic ballast without damping element and thus without high-frequency interference suppression.
  • FIG. 4 also shows the standard value curves for the quasi-peak (QP) and average values (AV) to be observed. In the frequency range from 10 to 30 MHz, the detected interference levels clearly exceed the standard values to be observed with regard to the quasi-peak (60 dB ⁇ V) and average values (50 dB ⁇ V), the excesses being approximately 5 dB ⁇ V.
  • QP quasi-peak
  • AV average values
  • FIG. 5 shows an interference spectrum of the same lamp with electronic ballast with lamp terminal and integrated damping element with a circuit arrangement according to FIG. 1.
  • the standard values prescribed in the frequency range between 10 and 30 MHz with respect to quasi-peak (QP) and average values (AV) are undershot , where the undershoots are approximately 5 dB ⁇ V.
