Preferred expansion scheme describes in the dependent claims.
At this, term " luminaire " is different with term " lamp " usually, does not relate to illuminator itself; Promptly do not relate to and be responsible for the running stores that actual light produces; And relating to a kind of lighting device, it has illuminator or is used to hold illuminator, promptly holds lamp.So luminaire has housing and has cover, reflector, translucent covering glass or the like usually.
Basic thought of the present invention is; In luminaire or ballast, be provided with attenuating elements; This attenuating elements produces the high frequency radiation loss through the specific attenuation characteristics of material in interested frequency range, and the interfering resonance phenomena and reduce its amplitude of decaying thus.At this, particularly consider material with suitable magnetic properties, these materials can be decayed through the high-frequency loss of magnetic.This is particularly suitable for ferromagnetic ceramic raw material, and the raw material that particularly also is made up of iron oxide, these raw materials are also as decay ferrite (Daempfungsferrite) and known.
At this, this attenuating elements preferably should not be integrated into (ferrite also can lack conductive capability to this) in the conductor itself, but should only be installed near the conductor.Preferably, attenuating elements surrounds conductor, and its mode is that it is the body that has the break-through opening.Particularly consider so-called pearl (being the body of the little similar ball that has the hole), ring or tubule.
Under ballast situation required for protection, the circuit that decay is on the PE of ballast binding post and the ballast housing or between the ground connection contact site on its corresponding parts.Thus, the line current that relates to resonance phenomena must pass through this circuit.
Under the situation of luminaire, the PE binding post of luminaire usually on the whole be integrated in luminaire in the PE binding post of ballast different, perhaps ballast possibly not have special-purpose PE binding post yet.Preferably, the circuit that decay by attenuating elements at this between the whole ground connection contact site of the ground connection contact site of the PE of luminaire binding post and luminaire housing parts that resonance phenomena together is responsible for or luminaire housing.With luminaire housing (parts) so electric capacity related and that participate in resonance phenomena causes the electric current through the decay of this circuit.
On the other hand, the conductive shell of integrated ballast also can relate to sizable electric capacity, makes that equally preferably this circuit is between the ground connection contact site of the PE of luminaire binding post and ballast housing.Preferably either way exist.Especially; Can carry out the contact of ballast ground connection with respect to luminaire housing (parts), feasible decay through the circuit between the ground connection contact site on the PE of luminaire binding post and the luminaire housing (parts) has also together detected the electric current to ballast housing.
In all deformation programs of the present invention, in principle preferably, attenuating elements is integrated in the binding post.When referring to attenuating elements so far and will decay circuit between PE binding post and the definite ground connection contact site, statement " between " zone that begins from the connection contact site that is used for outside line of reality meaned.Preferably be integrated in the terminal and mean; Attenuating elements will be integrated in the binding post body; Promptly for example such under near the situation of the attaching plug (Luesterklemme) the electric-conductor between the connection contact site of connection contact site common, that be used for outside line and inside; Exactly, particularly has the form of surrounding this electric-conductor.Term " is integrated in " and means at this; Attenuating elements will comprise or remain in the parts that comprise its insulation holding device; Make it together installed and be installed in the terminal, and maybe even can buy by luminaire manufacturer or ballast manufacturer and terminal.
Description of drawings
Fig. 1-3 shows have the luminaire binding post three devices in a circuit according to the invention, and wherein said luminaire binding post has integrated attenuating elements.
Fig. 4 shows the interference spectrum that under situation about High-frequency Interference not being decayed, has the luminaire of electric ballast.
Fig. 5 shows and has electric ballast and according to the interference spectrum of the luminaire of luminaire binding post of the present invention, wherein this luminaire binding post has according to the integrated attenuating elements in the circuit of Fig. 1.
Embodiment
Fig. 1 shows the circuit arrangement that has luminaire binding post LK according to of the present invention, and this luminaire binding post LK has the integrated attenuating elements F of the luminaire that is used to have electric ballast EVG.Attenuating elements F is the ferrite pearl of high frequency absorption, and is integrated in the luminaire binding post itself.At this, the ferrite pearl connects at binding post contact site that is used for outside PE electrical network feed line and the conduction that guides between the internal wiring of luminaire housing.So the track section that has attenuating elements F is connected between luminaire housing and the earthing conductor PE, wherein pass through luminaire housing (perhaps circuit) and pass through attenuating elements at last to link to each other with earthing conductor PE at this electric ballast EVG.In this circuit arrangement; Attenuating elements F has absorbed interference spectrum (this interference spectrum is by the resonance between the housing of luminaire housing and electric ballast, is particularly produced by the capacitive couplings between luminaire housing and the environment), and attenuate high frequency is disturbed in this way.
Fig. 2 shows the distortion according to the circuit arrangement of Fig. 1.At this, the ferrite pearl is integrated in the luminaire binding post equally, yet only is set on the PE connection line, and ballast EVG is connected on the outside PE circuit through the luminaire binding post by this PE connection line.The housing of luminaire is perhaps as illustrated irrespectively to be connected on the outside PE feed line with it, and perhaps can be constructed as does not in this embodiment have the ground connection contact site fully yet, for example such in the situation of plastics luminaire.At this,, and in decay according to the present invention, be not considered so the capacitive influences of luminaire housing does not play a decisive role.
On the contrary, in the deformation program in Fig. 3, only influence the conducting bridge that leads to like line through the ferrite pearl F that is integrated into equally in the luminaire binding post: this link tester is toward the ground connection contact site of luminaire housing.Because it is different with the deformation program among Fig. 1; Ballast EVG is connected on the outside PE circuit at this feed line that passes to the luminaire binding post; And this feed line does not together detect through the ferrite integument, does not therefore together consider the capacitive influences of EVG housing here.This influence can be unconspicuous in individual cases.Different with accompanying drawing, because the ground connection of luminaire housing also can be saved EVG housing conduction and ground connection.Yet can certainly exist the second ferrite pearl or common ferrite pearl to be used for the frame ground feed line.
Fig. 4 shows the interference spectrum (under the situation of 50 Ω, unit is dB μ V) that under the situation that does not have attenuating elements and do not have High-frequency Interference to suppress thus, has the luminaire of electric ballast.In addition, the standard value curve that will observe that is directed against accurate peak (QP) value and mean value (AV) has been shown in Fig. 4.Determined interference level obviously surpasses the standard value about quasi-peak value (60dB μ V) and mean value (50dB μ V) that will observe in the frequency range of 10MHz to 30MHz, wherein overshoot about 5dB μ V.
