Elektrisches LeuchtmittelElectric light source
Die Erfindung betrifft ein elektrisches Leuchtmittel, bestehend aus Kaltkatodenleuchtstofflampe mit Beschaitung, das insbesondere für den Einsatz bei hoher Einschalthäufigkeit, langer Lebensdauer bei geringer Leistung geeignet ist.The invention relates to an electrical lighting device consisting of a cold cathode fluorescent lamp with a circuit, which is particularly suitable for use with a high switching frequency, a long service life and low power.
Bekannt sind Kaltkatodenleuchtstofflampen oder Glimmentladungslampen mit Leuchtstoffbeschichtung unter anderem aus der DE-OS 2840 102 A1, in der eine Glimmentladungslampe für die Signalisierung verschiedener Betriebszustände in den beiden Röhrenhälften mit farblich unterschiedlich emittierenden Leuchtstoffen versehen ist. Die Farbumschaltung wird durch zwei bis nahe zur Gefäßmitte reichende Elektroden erreicht, die je nach gewünschtem Anzeigeeffekt mit Spannung unterschiedlicher Polarität beaufschlagt werden, so daß die entsprechende Lampenhälfte aktiviert wird und den zugehörigen Leuchtstoff anregt.Cold cathode fluorescent lamps or glow discharge lamps with a fluorescent coating are known, among other things, from DE-OS 2840 102 A1, in which a glow discharge lamp is provided with fluorescent materials emitting different colors in the two halves of the tube to signal different operating states. The color change is achieved by two electrodes that extend almost to the middle of the vessel, which are supplied with voltage of different polarity depending on the desired display effect, so that the corresponding half of the lamp is activated and excites the corresponding fluorescent material.
In DE-OS 39 13 504 A 1 ist eine speziell gestaltete Becherelektrode für Kaltkatoden patentiert, bei der durch eine gezielt aufgebrachte Nickeloxidschicht erreicht wird, daß die Entladung nur in bestimmten Zonen der Elektrode ansetzt.DE-OS 39 13 504 A 1 patents a specially designed cup electrode for cold cathodes, in which a specifically applied nickel oxide layer ensures that the discharge only starts in certain zones of the electrode.
Bekannt ist nach Gebrauchsmuster DE-OS 29501 343.5 ein elektrisches Leuchtmittel, bei dem die Leuchtstofflampe über eine Spannungsverdopplerschaltung, die aus einer Graezbrückenschaltung abgeleitet wurde, mit Gleichspannung betrieben wird, wobei sich die Katoden durch spezielle Materialien und Beschichtungen auszeichnen. Das angestrebte Ziel des Betriebes einer solchen Glimmleuchtstofflampe ohne Verwendung eines Spannungserhöhenden Transformators wird mittels der oben erwähnten Spannungsverdopplerschaltung, speziellen Hilfselektroden und Zündstreifen erreicht.According to utility model DE-OS 29501 343.5, an electrical light source is known in which the fluorescent lamp is operated with direct current via a voltage doubler circuit derived from a Graez bridge circuit, whereby the cathodes are characterized by special materials and coatings. The desired goal of operating such a glow fluorescent lamp without using a voltage-increasing transformer is achieved by means of the voltage doubler circuit mentioned above, special auxiliary electrodes and ignition strips.
Nachteilig bei allen dargestellten Glimmleuchtstofflampen ist, daß sie für den Anwender kein gebrauchsfähiges Leuchtmittel darstellen, da Entladungsrohr und Spannungsversorgung keine unmittelbar am Netz anschließenbare Einheit darstellen.The disadvantage of all the glow fluorescent lamps shown is that they do not represent a usable light source for the user, since the discharge tube and power supply do not represent a unit that can be directly connected to the mains.
Üblicherweise werden Entladungsrohr, Beschaitung oder der Transformator elektrisch miteinander verbunden und müssen danach in ein Gehäuse eingebracht werden, welches den Berührungschutz oder weitere Schutznotwendigkeiten, wie Schutz gegen Staub oder Wasser sichert. Ein weiterer Nachteil der oben genannten Aufbauten und Schaltungen ist der hohe Bedarf an Bauelementen.Usually, the discharge tube, wiring or transformer are electrically connected to one another and then have to be placed in a housing that provides protection against contact or other necessary protection, such as protection against dust or water. Another disadvantage of the above-mentioned structures and circuits is the high demand for components.
Der in den Schutzansprüchen angegebenen Erfindung liegt die Aufgabe zugrunde, ein Leuchtmitte!, bestehend aus Glimmleuchtstofflampe , Beschallung und Umhüllung zu schaffen, dasThe invention specified in the claims is based on the task of creating a light source! consisting of a glow fluorescent lamp, sound system and casing, which
einen 230-V-Netzbetrieb ohne Transformator erlaubt; eine sehr hohe Lebensdauer und Schaltfestigkeit besitzt; die Zündung von Glimmleuchtstofflampen mit einer Positiven Säule von mehr als 200 mm direkt am 230-V-Netz gestattet; ein direkt zu verwendendes allen Schutzanforderungen gerecht werdendes Leuchtmittel zu schaffen.allows 230 V mains operation without a transformer; has a very long service life and switching strength; allows the ignition of glow fluorescent lamps with a positive column of more than 200 mm directly from the 230 V mains; to create a lamp that can be used directly and meets all safety requirements.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, daßAccording to the invention, the object is achieved in that
1. die Glimmleuchtstofflampe an einer speziell dimensionierten Spannungsverdopplerschaltung betrieben wird, die die Lampe mit Gleichspannung versorgt;1. the glow fluorescent lamp is operated on a specially dimensioned voltage doubler circuit that supplies the lamp with direct voltage;
2. der Katodenfall durch Anwendung von mangan- oder lanthanhaltigen Elektroden erniedrigt wird;2. the cathode drop is reduced by using electrodes containing manganese or lanthanum;
3. Das Entladungsrohr und die Beschattung in entsprechende Schutzhüllen eingebracht wird, die mittels Leitungen miteinander verbunden sind.3. The discharge tube and the shading are placed in appropriate protective covers which are connected to each other by means of cables.
In Figur 1 ist der elektrische Aufbau erkennbar:The electrical structure can be seen in Figure 1:
Das leuchtstoffbeschichtete, edelgas- und quecksilberdampfgefüllte Entladungsrohr (1) besitzt eine Anode (5) und eine Katode (6). Ein Schutzwiderstand oder eine Schutzwiderstandskombination (2) dienen der Stromeinstellung. Die Lampenspannung wird über eine Spannungsverdopplerschaltung bestehend, aus jeweils zwei Kondensatoren (3) und zwei Dioden (4), erzeugt.The fluorescent-coated discharge tube (1) filled with noble gas and mercury vapor has an anode (5) and a cathode (6). A protective resistor or a protective resistor combination (2) is used to adjust the current. The lamp voltage is generated via a voltage doubler circuit consisting of two capacitors (3) and two diodes (4).
Figur 2 beschreibt den äußeren Aufbau.Figure 2 describes the external structure.
Das Entladungsgefäß (1) besitzt eine Abdeckkappe (7) und eine Durchführung (8). Alle drei Bauelemente sind von einer durchsichtigen Plasteschicht (9) so umhüllt, daß nur die Befestigungsbereiche (10) von Abdeckkappe (7) und Durchführung (9) frei von dieser Umhüllung sind.The discharge vessel (1) has a cover cap (7) and a feedthrough (8). All three components are covered by a transparent plastic layer (9) so that only the fastening areas (10) of the cover cap (7) and feedthrough (9) are free of this covering.
Die Beschaltung ist in einem Elektronikgefäß (11) untergebracht, das mit flexiblen Leitungen (12), (13) mit dem Entladungsgefäß und dem Netz verbunden ist.The circuitry is housed in an electronics vessel (11) which is connected to the discharge vessel and the mains by flexible cables (12), (13).
