Description

Die Erfindung bezieht sich auf eine Fingernagel- oder Fußnagelaushärtevorrichtung zum Aushärten von lichthärtendem Fingernagel-oder Fußnagelersatz wie sie beispielsweise aus der Veröffentlichung von der pharmaceuticals, Lee UV nails, 1975, USA bekannt geworden ist.The invention relates to a fingernail or toenail curing device for curing light-curing fingernail or toenail replacements, as has become known, for example, from the publication by pharmaceuticals, Lee UV nails, 1975, USA.

Künstliche Finger- oder Fußnägel, die zur Ergänzung teilweise beschädigter Nägel oder beispielsweise als Nagelersatz so lange dienen, bis ein natürlicher Nagel nach einem Unfall nachgewachsen ist, wurden bislang aus chemisch härtenden Substanzen hergestellt. Aus der US-A-3896 014 ist eine Nagellackzusammensetzung bekannt, zu deren Aushärtung die Strahlung einer Bogenentladungslampe vorsehen ist.Artificial fingernails or toenails, which are used to supplement partially damaged nails or, for example, to replace nails until a natural nail has regrown after an accident, have so far been produced from chemically curing substances. From US-A-3896 014 a nail polish composition is known, for the curing of which the radiation from an arc discharge lamp is provided.

Die Verwendung von lichthärtenden Substanzen in der medizinischen Technik, beispielsweise zum Stillegen gebrochener Gliedmaßen ist an sich bekannt. Diese Substanzen härten unter Lichteinstrahlung, vorzugsweise im UV-Bereich aus (unter Licht soll hier wie im Folgenden nicht nur sichtbares Licht, sondern auch ultraviolette Strahlung verstanden werden).The use of light-curing substances in medical technology, for example for the restoration of broken limbs, is known per se. These substances harden under the influence of light, preferably in the UV range (light, as in the following, should not only be understood to mean visible light, but also ultraviolet radiation).

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Aushärten von lichthärtendem Fingernagel- oder Fußnagelersatz zu schaffen, die einfach aufgebaut und kostengünstig herzustellen ist und mit der künstliche Fingernägel oder Fußnägel unter präzise reproduzierbaren Bedingungen in zuverlässiger Weise ausgehärtet werden können.The invention has for its object to provide a device for curing light-curing fingernail or toenail replacement, which is simple and inexpensive to manufacture and can be cured in a reliable manner with the artificial fingernails or toenails under precisely reproducible conditions.

Diese Aufgabe ist bei einer Vorrichtung der eingangs genannten Art, durch eine Auflageplatte und mindestens eine im Abstand zu der Auflageplatte angeordnete Niederdruckleuchtstoffröhre gelöst.This object is achieved in a device of the type mentioned at the outset by a support plate and at least one low-pressure fluorescent tube arranged at a distance from the support plate.

Die Strahlung einer Niederdruckleuchtstoffröhre, die üblicherweise in einem Spektralbereich von 320 nm bis 520 nm liegt, hat sich zur Aushärtung von künstlichen Finger- oder Fußnägeln als überraschend vorteilhaft erwiesen und zu gleichbleibenden Ergebnissen geführt. Dadurch, daß weiterhin erfindungsgemäß eine Auflageplatte für die Hand oder den Fuß des Patienten vorgesehen ist und somit der Abstand zwischen der Strahlungsquelle und dem zu behandelnden Objekt stets der gleiche ist, lassen sich konstante und somit reproduzierbare Bestrahlungsverhältnisse erzielen. Über- und Unterdosierungen der Strahlung, die durch zu geringen oder zu großen Abstand zwischen Strahlungsquelle und Objekt hervorgerufen werden könnten, werden vermieden.The radiation from a low-pressure fluorescent tube, which is usually in a spectral range from 320 nm to 520 nm, has proven to be surprisingly advantageous for curing artificial fingernails or toenails and has led to consistent results. The fact that, according to the invention, a support plate is provided for the hand or foot of the patient and thus the distance between the radiation source and the object to be treated is always the same, constant and thus reproducible radiation conditions can be achieved. Overdosing and underdosing of the radiation, which could be caused by too small or too large a distance between the radiation source and the object, are avoided.

Eine in konstruktionstechnischer Sicht besonders vorteilhafte Ausführungsform der Erfindung zeichnet sich dadurch aus, daß die Niederdruckleuchtstoffröhre an einem an der Auflageplatte befestigten Träger angeordnet ist. Auf diese Weise gibt sich ein kompaktes Gerät, bestehend aus Auflageplatte, Träger und Leuchtstoffröhre. Dabei kann vorteilhafterweise die Stromversorgung sowie der Sockel für die Niederdruckleuchtstoffröhre in dem Träger angeordnet sein.An embodiment of the invention which is particularly advantageous in terms of construction technology is characterized in that the low-pressure fluorescent tube is arranged on a support fastened to the support plate. In this way there is a compact device consisting of a support plate, support and fluorescent tube. The power supply and the base for the low-pressure fluorescent tube can advantageously be arranged in the carrier.

Nach einer besonders vorteilhaften Ausführungsform der Erfindung sind mehrere achsparallele, vorzugsweise vier bis sechs Niederdruckleuchtstoffröhren vorgesehen. Hierdurch läßt sich eine besonders gleichmäßige Bestrahlung sämtlicher Fingernägel einer Hand erzielen. Wenn dabei die Niederdruckleuchtstoffröhren nach einer weiteren vorteilhaften Weiterbildung des Erfindungsgedankens so angeordnet sind, daß die Schnittpunkte ihrer Längsachsen mit einer zu den Achsen senkrechten Ebenen auf einer bogenförmigen Kurve liegen, wird auch der Nagel am Daumen einer Hand der üblicherweise bei einer auf eine flache Platte gelegten Hand nahezu senkrecht zu dieser Platte steht, mit gleicher Intensität wie die anderen Nägel der Hand bestrahlt, da sich durch die Anordnung der Niederdruckleuchtstoffröhren in Bogenform gewissermaßen ein Bestrahlungstunnel ergibt.According to a particularly advantageous embodiment of the invention, a plurality of axially parallel, preferably four to six, low-pressure fluorescent tubes are provided. In this way, a particularly uniform irradiation of all fingernails of one hand can be achieved. If the low-pressure fluorescent tubes are arranged according to a further advantageous development of the inventive concept so that the intersection of their longitudinal axes with a plane perpendicular to the axes lie on an arcuate curve, the nail on the thumb of a hand is usually the one placed on a flat plate Hand is almost perpendicular to this plate, irradiated with the same intensity as the other nails of the hand, since the arrangement of the low-pressure fluorescent tubes in an arc shape results in a radiation tunnel.

Unter sicherheitstechnischen Überlegungen hat sich eine Ausführungsform als besonders vorteilhaft erwiesen, bei der die Niederdruckleuchtstoffröhren U-förmig ausgebildet und einseitig gesockelt sind. Bei dieser Bauweise kann eine Seite der Leuchtstoffröhren völlig frei von Halterungen und elektrischen Anschlüssen gehalten werden. Zweckmäßigerweise wird die Hand oder der Fuß des Patienten von dieser freien Seite unter die Leuchtstoffröhren, d. h. auf die Auflageplatte gebracht. Eine Berührung mit den Röhrensockeln ist dabei vermieden. Ferner ist die beschriebene Ausführungsform auch unter konstruktionstechnischen Gesichtspunkten vorteilhaft, weil für die Leuchtstoffröhre bzw. die Leuchtstoffröhren nur ein einziger Träger benötigt wird. Entsprechend niedrig sind die Herstellungskosten.Under safety-related considerations, an embodiment in which the low-pressure fluorescent tubes are U-shaped and have a base on one side has proven particularly advantageous. With this design, one side of the fluorescent tubes can be kept completely free of brackets and electrical connections. The patient's hand or foot is expediently placed under the fluorescent tubes from this free side, i. H. brought on the platen. Touching the tube bases is avoided. Furthermore, the described embodiment is also advantageous from a constructional point of view because only a single carrier is required for the fluorescent tube or tubes. The manufacturing costs are correspondingly low.

Nach einer weiteren Ausführungsform sind Niederdruckleuchtstoffröhren mit einer Quecksilberdampffüllung vorgesehen. Mit diesen Röhren, die Strahlung mit einer Wellenlänge von 320 nm bis 520 nm vorzugsweise mit einer Wellenlänge von 360 nm bis 450 nm emitieren, konnten hervorragende Ergebnisse bei der Aushärtung von künstlichem Nagelersatz erzielt werden.According to a further embodiment, low-pressure fluorescent tubes with a mercury vapor filling are provided. With these tubes, which emit radiation with a wavelength of 320 nm to 520 nm, preferably with a wavelength of 360 nm to 450 nm, excellent results were achieved in the curing of artificial nail replacement.

Nach einer weiteren vorteilhaften Ausführungsform ist ein Schutzgehäuse mit einer an die Form einer Hand oder eines Fußes angepaßten Eingriffsöffnung vorgesehen, durch das die Lichtquelle vor Beschädigung und andererseits die Umgebung vor austretender Strahlung geschützt wird. Ferner deckt das Schutzgehäuse auch alle elektrischen Teile, wie beispielsweise die Spannungsversorgung für die Leuchtstoffröhren ab. Wenn das Schutzgehäuse tunnelförmig ausgebildet ist und insbesondere nach einer weiteren vorteilhaften Ausführungsform die Längsachse des tunnelförmigen Schutzgehäuses parallel zur Längsachse der Niederdruckleuchtstoffröhren ist, kann die Innenwand des Schutzgehäuses als Reflektor verwendet werden, der die Gleichmäßigkeit der Ausleuchtung des Objektes innerhalb der Vorrichtung erhöht und darüber hinaus die Strahlung der Leuchtstoffröhren wirksam ausnützt. Nach einer weiteren vorteilhaften Ausführungsform der Erfindung wird die Reflektionswirkung des weiteren dadurch erhöht, daß die Innenseite des Schutzgehäuses mit einem Reflektor belegt wird. Dieser kann aus einer Folie oder aus plattenförmigem reflektierendem Material bestehen.According to a further advantageous embodiment, a protective housing is provided with an engagement opening adapted to the shape of a hand or a foot, by means of which the light source is protected from damage and, on the other hand, the environment is protected from emerging radiation. Furthermore, the protective housing also covers all electrical parts, such as the voltage supply for the fluorescent tubes. If the protective housing is tunnel-shaped and in particular according to a further advantageous embodiment, the longitudinal axis of the tunnel-shaped protective housing is parallel to the longitudinal axis of the low-pressure fluorescent tubes, the inner wall of the protective housing can be used as a reflector, which increases the uniformity of the illumination of the object within the device and also effectively uses the radiation from the fluorescent tubes. According to a further advantageous embodiment of the invention, the reflective effect is further increased by covering the inside of the protective housing with a reflector. This can consist of a film or of plate-shaped reflective material.

Vorteilhafterweise werden in dem Schutzgehäuse Lüftungsschlitze vorgesehen, so daß die durch die Leuchtstoffröhren und die Spannungsversorgung erwärmte Luft wirksam abgezogen wird. Eine Erwärmung des Innenraums der Vorrichtung, die bei empfindlichen Patienten leicht zu Angstgefühlen führen könnte, wird damit vermieden.Advantageously, ventilation slots are provided in the protective housing, so that the air heated by the fluorescent tubes and the voltage supply is effectively drawn off. This avoids heating the interior of the device, which could easily lead to feelings of fear in sensitive patients.

Neben der Forderung der gleichmäßigen Ausleuchtung des zu bestrahlenden Objektes, hat sich auch die Bestrahlungsdauer als ein die Qualität der Aushärtung wesentlich beeinflussender Faktor erwiesen. Nach einer besonders vorteilhaften Ausführungsform der Erfindung ist daher eine Meßvorrichtung vorgesehen, die die Bestrahlungszeit erfaßt.In addition to the requirement for uniform illumination of the object to be irradiated, the duration of the irradiation has also proven to be a factor which significantly influences the quality of the curing. According to a particularly advantageous embodiment of the invention, a measuring device is therefore provided which detects the irradiation time.

Nach einer besonders vorteilhaften Ausführungsform der Erfindung wird die Bestrahlungszeit gewissermaßen automatisch mit Hilfe einer an der Auflageplatte angeordneten Lichtschranke erfaßt, die einen Zeitgeber dann auslöst, wenn eine Hand oder ein Fuß zu Bestrahlungszwecken in die Vorrichtung eingeführt wird.According to a particularly advantageous embodiment of the invention, the irradiation time is, as it were, recorded automatically with the aid of a light barrier arranged on the support plate, which triggers a timer when a hand or foot is inserted into the device for irradiation purposes.

Besonders vorteilhaft ist dabei, wenn der Zeitgeber nach Ablauf einer bestimmten, vorzugsweise einstellbaren, Zeit ein Steuersignal erzeugt, das dem Eingang eines akustischen Signalgebers zugeführt wird. Der akustische Signalgeber deutet somit nach Ablauf einer bestimmten Zeit das Ende des Behandlungsvorganges an.It is particularly advantageous if, after a certain, preferably adjustable, time has elapsed, the timer generates a control signal which is fed to the input of an acoustic signal transmitter. The acoustic signal generator thus indicates the end of the treatment process after a certain time.

Dabei wird nach einer weiteren Ausführungsform der Erfindung der Signalgeber mit dem Empfänger der Lichtschranke verbunden und erhält von diesem ein Freigabesignal, wenn der Lichtweg in der Lichtschranke unterbrochen ist. Durch dieses Freigabesignal wird sichergestellt, daß nur dann ein akustisches Signal durch den Signalgeber abgegeben wird, wenn der Zeitgeber abgelaufen ist und das zu behandelnde Objekt sich noch in der Vorrichtung befindet.According to a further embodiment of the invention, the signal transmitter is connected to the receiver of the light barrier and receives an enable signal from the latter when the light path in the light barrier is interrupted. This release signal ensures that an acoustic signal is only emitted by the signal generator when the timer has expired and the object to be treated is still in the device.

Nach einer weiteren Ausführungsvariante ist vorgesehen, daß nach Ablauf des Zeitgebers unmittelbar die Stromzufuhr zu den Niederdruckleuchtstoffröhren durch ein Relais unterbrochen wird, so daß eine über die vorgeschriebene Zeitdauer hinausgehende Bestrahlung nicht möglich ist. Die Erfindung wird im folgenden anhand der in den Figuren 1 bis 4 schematisch dargestellten Ausführungsbeispiele näher erläutert. Es zeigt:

  • Fig. 1 Eine Vorrichtung gemäß der Erfindung in Frontansicht;
  • Fig. 2 Eine Ansicht der Vorrichtung wie in Figur 1, jedoch bei abgenommenem Schutzgehäuse;
  • Fig. 3 Eine Draufsicht der in Figur 2 dargestellten Vorrichtung;
  • Fig. 4 Ein Blockschaltbild einer Bestrahlungszeitmeßeinrichtung;
  • Fig. 5 Eine Vorderansicht einer weiteren Ausführungsform.
According to a further embodiment variant, it is provided that, after the timer has expired, the power supply to the low-pressure fluorescent tubes is immediately interrupted by a relay, so that irradiation beyond the prescribed period of time is not possible. The invention is explained in more detail below with reference to the exemplary embodiments shown schematically in FIGS. 1 to 4. It shows:
  • Fig. 1 A device according to the invention in front view;
  • 2 shows a view of the device as in FIG. 1, but with the protective housing removed;
  • 3 shows a top view of the device shown in FIG. 2;
  • 4 shows a block diagram of an irradiation time measuring device;
  • Fig. 5 is a front view of another embodiment.

In Figur 1 ist eine Vorrichtung zum Aushärten von lichthärtendem Fingernagel- oder Fußnagelersatz in der Frontansicht dargestellt. Es ist eine Auflegeplatte 1 zu erkennen, an deren einem Ende senkrecht zur Grundfläche der Auflageplatte 1 ein Träger 3 befestigt ist (siehe auch Figuren 2 und 3). Der Träger 3 enthält sechs Halterungen für U-förmige, einseitig gesockelte Niederdruckleuchtstoffröhren 2a-2f. Die Leuchtstoffröhren 2a-2f sind auf dem Träger so angeordnet, daß sie auf diesem auf einer bogenförmigen Kurve liegen. Dabei handelt es sich um einen weit auseinandergezogenen breiten Bogen, der etwas breiter als eine menschliche Hand oder ein menschlicher Fuß ist. Die U-förmigen Leuchtstoffröhren sind dabei so befestigt, daß die Flächennormale einer durch die beiden Mittelachsen der Rohrteile einer Leuchtstoffröhre gehende Fläche etwa in den mittleren Bereich der Auflegeplatte 1 weist, um dort eine optimale Strahlungsausnutzung zu erzielen.In Figure 1, a device for curing light-curing fingernail or toenail replacement is shown in the front view. A support plate 1 can be seen, at one end of which a support 3 is attached perpendicular to the base of the support plate 1 (see also FIGS. 2 and 3). The carrier 3 contains six brackets for U-shaped, low-pressure fluorescent tubes 2a-2f which are capped on one side. The fluorescent tubes 2a-2f are arranged on the carrier so that they lie on an arcuate curve thereon. It is a widely spread wide arch that is slightly wider than a human hand or foot. The U-shaped fluorescent tubes are fastened so that the surface normal of a surface passing through the two central axes of the tube parts of a fluorescent tube points approximately in the central region of the support plate 1 in order to achieve optimum radiation utilization there.

Wie in Figur 1 zu erkennen ist, ist die Vorrichtung mit einem Schutzgehäuse 4 bedeckt, das an der Frontseite eine an die Form einer menschlichen Hand oder eines Fusses angepaßte Eingriffsöffnung 5 aufweist. Das Schutzgehäuse ist tunnelförmig und erstreckt sich in der gleichen Richtung wie die auf dem Träger 3 angeordneten Leuchtstoffröhren. Es ist an seiner Innenseite mit einer reflektierenden Folie (nicht dargestellt) belegt. Auf der Platte 1 ist eine Lichtschranke bestehend aus einem Sender 6 und einem Empfänger 7 angeordnet. Der Sender besteht üblicherweise aus einer Leuchtdiode und der Empfänger 7 aus einer Photozelle. Wie in Figur 3 zu erkennen ist, liegt die Lichtschranke im Frontbereich der Auflageplatte 1, d. h. unmittelbar im Bereich der Eingriffsöffnung 5 des Schutzgehäuses 4. In dem Träger 3 sind (nicht dargestellt) die Spannungsversorgung sowie die elektronischen Teile für die Bestrahlungszeitmeßeinrichtung untergebracht.As can be seen in FIG. 1, the device is covered with a protective housing 4, which on the front side has an engagement opening 5 adapted to the shape of a human hand or foot. The protective housing is tunnel-shaped and extends in the same direction as the fluorescent tubes arranged on the carrier 3. It is covered on the inside with a reflective film (not shown). A light barrier consisting of a transmitter 6 and a receiver 7 is arranged on the plate 1. The transmitter usually consists of a light emitting diode and the receiver 7 of a photocell. As can be seen in Figure 3, the light barrier is located in the front area of the support plate 1, i. H. directly in the area of the engagement opening 5 of the protective housing 4. The voltage supply and the electronic parts for the irradiation time measuring device are accommodated in the carrier 3 (not shown).

In Figur 3 ist zu Illustrationszwecken strichliert eine in die Vorrichtung eingeführte Hand angedeutet.A hand inserted into the device is indicated by dashed lines in FIG. 3 for illustration purposes.

Der Aufbau der Zeitmeßeinrichtung wird anhand des Blockschaltbildes gemäß Figur 4 erläutert. Eine Stromversorgung 10 versorgt den Sender 6 der Lichtschranke sowie einen elektronischen Zeitgeber 8. Der Auslöseeingang des Zeitgebers 8 ist mit dem Empfänger 7 der Lichtschranke verbunden. Der Signalausgang des Zeitgebers 8 ist mit einem Steuersignaleingang eines akustischen Signalgebers 9 verbunden. Ferner ist der Ausgang des Lichtschrankenempfängers 7 an einen Freigabesignaleingang des Signalgebers 9 angeschlossen.The structure of the time measuring device is explained using the block diagram according to FIG. 4. A power supply 10 supplies the transmitter 6 of the light barrier and an electronic timer 8. The trigger input of the timer 8 is connected to the receiver 7 Photoelectric sensor connected. The signal output of the timer 8 is connected to a control signal input of an acoustic signal generator 9. Furthermore, the output of the light barrier receiver 7 is connected to an enable signal input of the signal generator 9.

Die Vorrichtung arbeitet wie folgt:The device works as follows:

Durch eine Stromversorgung werden die Quecksilberdampf-NiederdruckLeuchtstoffröhren 2a-2f mit einer Betriebsspannung von etwa 60 Volt beaufschlagt. Die Leuchtstoffröhren geben sichtbares Licht sowie Licht im nahen UV-Bereich ab. Durch die Eingriffsöffnung 5 in dem Schutzgehäuse 4 wird die zu behandelnde Hand oder der zu behandelnde Fuß eingeführt. Dadurch, daß die Leuchtstoffröhren 2a-2f in Form eines breiten Bogens angeordnet sind, werden alle Nägel einer Hand oder eines Fußes gleichmäßig ausgeleuchtet. Da bei einer in natürlicher Weise auf die Auflegeplatte 1 aufgelegten Hand der Daumennagel etwa senkrecht zur Grundfläche der Auflegeplatte 1 steht, wird im Falle einer rechten Hand der Daumennagel vorwiegend durch die Niederdruckleuchtstoffröhre 2a beleuchtet. Im Falle einer linken Hand wäre für die Beleuchtung des Daumennagels überwiegend die Leuchtstoffröhre 2f verantwortlich. Dadurch, daß das Schutzgehäuse 4 innenseitig mit einer reflektierenden Folie belegt ist, wird auch das in Richtung auf das Schutzgehäuse von den Niederdruckleuchtstoffröhren 2a-2f abgestrahlte Licht in Richtung auf das zu behandelnde Objekt geleitet. Bei Einführen einer Hand oder eines Fußes in die Eingriffsöffnung 5 wird der von dem Sender 6 ausgehende von dem Empfänger 7 aufgefangene Lichtstrahl unterbrochen, so daß der Empfänger 7 einen Impuls an den Zeitgeber 8 (siehe Figur 4) abgibt. Dadurch wird der Zeitgeber 8 gestartet. Nach Ablauf einer vorgegebenen, einstellbaren Zeit, gibt der Zeitgeber 8 einen Impuls an den Signalgeber 9. Wenn der Signalgeber 9 gleichzeitig von dem Empfänger 7 eine Freigabesignal empfängt, d. h. wenn der Lichtstrahl der Lichtschranke bei Ablauf des Zeitgebers noch unterbrochen ist, gibt der Signalgeber 9 ein akustisches Warnsignal ab, das auf den Ablauf der Behandlungszeit hinweist.An operating voltage of approximately 60 volts is applied to the low-pressure mercury vapor fluorescent tubes 2a-2f by a power supply. The fluorescent tubes emit visible light and light in the near UV range. The hand or foot to be treated is inserted through the engagement opening 5 in the protective housing 4. Because the fluorescent tubes 2a-2f are arranged in the form of a wide arc, all the nails of a hand or a foot are illuminated uniformly. Since the thumb nail is placed approximately perpendicular to the base of the mounting plate 1 when the hand is placed naturally on the mounting plate 1, in the case of a right hand the thumb nail is predominantly illuminated by the low-pressure fluorescent tube 2a. In the case of a left hand, the fluorescent tube 2f would be mainly responsible for illuminating the thumbnail. Because the protective housing 4 is coated on the inside with a reflective film, the light emitted in the direction of the protective housing by the low-pressure fluorescent tubes 2a-2f is also directed in the direction of the object to be treated. When a hand or foot is inserted into the engagement opening 5, the light beam emitted by the receiver 7 and emitted by the transmitter 6 is interrupted, so that the receiver 7 emits a pulse to the timer 8 (see FIG. 4). This starts the timer 8. After a predetermined, adjustable time, the timer 8 gives a pulse to the signal generator 9. If the signal generator 9 simultaneously receives an enable signal from the receiver 7, i. H. if the light beam from the light barrier is still interrupted when the timer expires, the signal generator 9 emits an acoustic warning signal which indicates the expiry of the treatment time.

In Figur 5 ist eine weitere Ausführungform dargestellt, bei der abweichend von der Ausführungsform gemäß Figur 1 nur eine einzige, zentral angeordnete Niederdruckleuchtstoffröhre 2 vorgesehen ist. Diese Vorrichtung ist insbesondere kostengünstig herzustellen. Überraschenderweise hat sich gezeigt, d3ß bei Verwendung des tunnelförmigen, an seiner Innenseite mit einer Reflektionsfolie belegten Schutzgehäuses 4 auch mit dieser vereinfachten Vorrichtung zumindest zufriedenstellende Ergebnisse bei der Aushärtung erzielt werden konnten.FIG. 5 shows a further embodiment, in which, in deviation from the embodiment according to FIG. 1, only a single, centrally arranged low-pressure fluorescent tube 2 is provided. This device is particularly inexpensive to manufacture. Surprisingly it was found, that 3 ß using the tunnel-shaped, occupied on its inner side with a reflection film protective housing 4, even with this simplified device at least satisfactory results in curing could be obtained.
