Description

Polarisiertes Licht ausstrahlende Behandlungsleuchte für den Handbetrieb Treatment light emitting polarized light for manual operation

Die Erfindung betrifft eine polarisiertes Licht ausstrahlende Behandlungsleuchte zur Biostimulierung mit polarisiertem Licht, Im einzelnen betrifft die Erfindung eine Behandlungsleuchte, welche polarisiertes Licht mit einer bestimmten Intensität und Wellenlänge ausstrahlt, und dabei einen bestimmten Flächenbereich abdeckt.The invention relates to a treatment light emitting polarized light for biostimulation with polarized light. In particular, the invention relates to a treatment light which emits polarized light with a certain intensity and wavelength, and thereby covers a certain area.

In der DE-PS 32 20 218 ist die allgemeine biostimulierende Wirkung von polarisiertem Licht beschrieben. Insbesondere Figur 5 dieser Literaturstelle zeigt eine Behandlungsleuchte, bei der ein Polarisationsfilter angewendet wird. Die Lampe ist für die Erzeugung eines Lichtbündels mit etwa 55 mm Durchmesser geeignet und die Lampenleistung beträgt 150 W. Die Behandlungsleuchte erzeugt viel Wärme und wird mittels eines Ventilators gekühlt. Dabei geht viel Leistung in Form von Wärme verloren und der Wirkungsgrad ist relativ gering, wodurch auch ernste Kühlungsproblerne auftreten. Darüber hinaus ist die Handhabbarkeit dieser Leuchte unter gleichzeitiger Verwirklichung einer optimalen Kühlung sowie eines optimalen Wirkungsgrads nicht optimiert.DE-PS 32 20 218 describes the general biostimulating effect of polarized light. In particular, FIG. 5 of this reference shows a treatment lamp in which a polarization filter is used. The lamp is suitable for generating a light bundle with a diameter of approximately 55 mm and the lamp output is 150 W. The treatment lamp generates a lot of heat and is cooled by a fan. A lot of power is lost in the form of heat and the efficiency is relatively low, which also causes serious cooling problems. In addition, the manageability of this lamp is not optimized while at the same time realizing optimal cooling and optimum efficiency.

Es ist eine Aufgabe der Erfindung eine derartigeIt is an object of the invention to do so

Behandlungsleuchte zu schaffen, bei welcher einerseits eine Konstruktion für eine günstige Handhabung geschaffen wird und andererseits eine optimale Funktion, beispielsweise hinsichtlich der Kühlung, bewirkt werden kann.To create a treatment light in which, on the one hand, a construction is created for convenient handling and, on the other hand, an optimal function, for example with regard to cooling, can be brought about.

Dies wird erfindungsgemäß durch die Merkmale im Anspruch 1 verwirklicht.This is achieved according to the invention by the features in claim 1.

Im einzelnen wird durch die Verwendung des Brewster- Polarisators mit dem Spiegelsandwich aus unmittelbar aufeinander aufliegenden Floatglasscheiben ein hoher Polarisator-Wirkungsgrad erzielt, während andererseits eine leichte Kühlbarkeit des Spiegelsandwiches aus Floatglasscheiben verwirklicht wird, weil beispielsweise keine isolierenden Luftspalte zwischen den einzelnen Glasscheiben vorhanden sind.In particular, the use of the Brewster polarizer with the mirror sandwich made of float glass panes lying directly on top of one another achieves a high polarizer efficiency while, on the other hand, the mirror sandwich made of float glass panes is easy to cool is realized because, for example, there are no insulating air gaps between the individual glass panes.

Weiter wird durch das unmittelbare Aufliegen der Floatglasscheiben aufeinander verhindert, daß der Polarisator durch Eindringen von Staubpartikeln zwischen die Floatglasscheiben verschmutzen kann. Dadurch wird eine längere Standzeit der Leuchte erzielt.Furthermore, the fact that the float glass panes lie directly on top of one another prevents the polarizer from becoming contaminated by the penetration of dust particles between the float glass panes. This means that the lamp has a longer service life.

Gemäß einer vorteilhaften Weiterbildung der Erfindung schließt die Lichtfilterplatte den zweiten Hohlzylinder ab. Dadurch wird der zweite Hohlzylinder lichtdurchlässig verschlossen, aber gleichzeitig mechanisch gegen das Eindringen von Staub abgedichtet. Entsprechend verschließt der Reflektor mittels einer Dichtung den ersten Hohlzylinder, wodurch die gesamte, aus dem ersten und dem zweiten Hohlzylinder bestehende Röhrenvorrichtung hermetisch abgedichtet ist und so vor einer Verschmutzung bewahrt bleibt.According to an advantageous development of the invention, the light filter plate closes off the second hollow cylinder. As a result, the second hollow cylinder is closed translucently, but at the same time mechanically sealed against the ingress of dust. Correspondingly, the reflector closes the first hollow cylinder by means of a seal, as a result of which the entire tube device consisting of the first and the second hollow cylinder is hermetically sealed and is thus protected from contamination.

Gemäß einer anderen vorteilhaften Weiterbildung ist dieAccording to another advantageous development, the

Lichtquellenanordnung in dem mittleren und dem vorderen Teil derart angeordnet, daß der Raum rings der Lichtquellenanordnung in der Nähe des Polarisators größer ist als in der Nähe des Reflektors. Dies hat einen optimalen Kühlluftstrom zur Folge.Light source arrangement arranged in the middle and front part such that the space around the light source arrangement in the vicinity of the polarizer is larger than in the vicinity of the reflector. This results in an optimal cooling air flow.

Gemäß einem vorteilhaften Ausführungsbeispiel liegt der erste Winkel zwischen 105° und 120°.According to an advantageous embodiment, the first angle is between 105 ° and 120 °.

Gemäß einer vorteilhaften Weiterbildung ist der Handgriff an seiner Außenfläche mit Einbuchtungen zum Aufnehmen der Finger an seiner der Lichtaustrittsöffnung des Vorderteils abgewandten Seite versehen. Dadurch läßt sich die Behandlungsleuchte optimal halten und auf die zu behandelnde Stelle richten, beispielsweise das Gesicht der anwendenden Person.According to an advantageous development, the handle is provided on its outer surface with indentations for receiving the fingers on its side facing away from the light exit opening of the front part. This allows the treatment light to be held optimally and directed towards the area to be treated, for example the face of the user.

Vorteilhaft sind die Schlitze des Handgriffs am unteren Ende desselben vorgesehen. Dadurch stellt der austretende Kühlluftstrom keine Behinderung dar. Gemäß einer vorteilhaften Weiterbildung der Erfindung weisen die Floatglasscheiben elliptische Formen auf und der Glasträger die Form einer elliptischen Aufnahmewanne mit einem elliptischen Boden und einer rings eines wesentlichen Teilbereichs des Bodens verlaufenden Wand, wobei die Wand mit einer Mehrzahl von Verriegelungsnasen versehen ist, welche in das Spiegelsandwich eingreifen und dieses so festhalten. Weiter kann das Spiegelsandwich auf der Schnittfläche der Röhrenvorrichtung direkt aufliegen, wodurch ein weiterer Halt gewährleistet ist.The slots of the handle are advantageously provided at the lower end thereof. As a result, the emerging cooling air flow is not a hindrance. According to an advantageous development of the invention, the float glass panes have elliptical shapes and the glass support has the shape of an elliptical receiving trough with an elliptical bottom and a wall running around a substantial partial area of the bottom, the wall being provided with a plurality of locking lugs which enter into the mirror sandwich intervene and hold it in this way. Furthermore, the mirror sandwich can rest directly on the cut surface of the tube device, which ensures a further hold.

Vorteilhaft ist die Lampe eine mit dem Reflektor zusammengebaute Metall-Halogen-Lampe und ist im Betrieb um wenigstens 5 % unterhitzt. Dadurch wird eine längere Standzeit der Lampe erzielt. Die Lampe ist besonders vorteilhaft so gestaltet, daß sie keinen oder nur einen verschwindend geringen Anteil an ultraviolettem Licht ausstrahlt.The lamp is advantageously a metal-halogen lamp assembled with the reflector and is underheated by at least 5% during operation. This results in a longer lamp life. The lamp is particularly advantageously designed in such a way that it emits no or only a negligible proportion of ultraviolet light.

Die Erfindung wird nachfolgend anhand eines bevorzugten Ausführungsbeispiels unter Bezugnahme auf die Zeichnung erläutert. In der Zeichnung zeigen:The invention is explained below using a preferred embodiment with reference to the drawing. The drawing shows:

Figur 10 eine vergrößerte Darstellung der in Figur 9 als "Detail 1" bezeichnete Einzelheit.Figure 10 is an enlarged view of the in Figure 9 as Detail called "Detail 1".

Die in Figur 1 dargestellte Behandlungsleuchte 1 besteht aus drei Konstruktionsteilen, d.h. einem Gehäuse 2, einer Lichtquellenanordnung 3 und einem Ventilator 4. Das Gehäuse 4 selbst besteht aus einem Handgriff 21, einem gewölbten Mittelteil 22 und einem Vorderteil 23, deren Form aus den Figuren 1 bis 4 deutlich ersichtlich ist. Das Gehäuse 2 ist vorzugsweise aus zwei aneinander angepaßten Kunststoffteilen hergestellt, die den Hohlraum zur Aufnahme der anderen Konstruktionsteile bestimmen.The treatment lamp 1 shown in Figure 1 consists of three construction parts, i.e. a housing 2, a light source arrangement 3 and a fan 4. The housing 4 itself consists of a handle 21, a curved central part 22 and a front part 23, the shape of which can be clearly seen from FIGS. 1 to 4. The housing 2 is preferably made of two plastic parts which are matched to one another and which determine the cavity for accommodating the other structural parts.

Die Lichtquellenanordnung 3 ist zentrisch in dem Mittelteil 22 und dem Vorderteil 23 des Gehäuses 2 in der in Figur 1 gezeigten Lage derart angeordnet, daß zwischen der inneren Gehäusewand und der Lichtquellenanordnung im wesentlichen überall ein Abstand gebildet ist. Der Begriff "zentrisch" bedeutet, daß dieser Abstand in der zur Zeichenebene der Figur 1 senkrechten Richtung an beiden Seiten gleich ist. Wie aus Figur 1 ersichtlich, ist die Lichtquellenanordnung 3 in der Zeichenebene nicht vollkommen zentrisch angeordnet.The light source arrangement 3 is arranged centrally in the middle part 22 and the front part 23 of the housing 2 in the position shown in FIG. 1 in such a way that a distance is formed essentially everywhere between the inner housing wall and the light source arrangement. The term "centric" means that this distance in the direction perpendicular to the plane of Figure 1 is the same on both sides. As can be seen from FIG. 1, the light source arrangement 3 is not arranged completely centrally in the drawing plane.

Die Lichtquellenanordnung 3 besteht aus zwei im stumpfen Winkel aneinandergeschweißten zylindrischen Röhren 31, 31, deren Achsen in einem Winkel von etwa 114° stehen, der dem Doppelten des Brewster-Winkels entspricht. Die beiden Röhren 31, 32 sind an dem Außenscheitel entlang einer Ebene angeschnitten, in welcher der Schnittpunkt der Röhrenachse liegt, und die dadurch entstandene elliptische Öffnung ist von einem Brewster- Polarisator 33 abgedeckt. Die Lichtquellenanordnung 3 ist aus Figur 5 in perspektivischer Darstellung ersichtlich.The light source arrangement 3 consists of two cylindrical tubes 31, 31 welded to one another at an obtuse angle, the axes of which are at an angle of approximately 114 °, which corresponds to twice the Brewster angle. The two tubes 31, 32 are cut at the outer apex along a plane in which the intersection of the tube axis lies, and the resulting elliptical opening is covered by a Brewster polarizer 33. The light source arrangement 3 can be seen in FIG. 5 in a perspective view.

Figur 6 zeigt einen Teil des Brewster-Polarisators 33 in Schnittdarstellung. Der Brewster-Polarisator 33 besteht aus einer Anzahl (z.B. 5) von hintereinander angeordneten, dünnen, planparallelen, elliptischen Floatglasscheiben 34, die unmittelbar, d.h. ohne eine Ausbildung eines Abstand dazwischen, aufeinander aufliegen. Die Floatglasscheiben 34 sind in einen Glasträger 35 eingefaßt, welcher in Figur 6 nur rein schematisch dargestellt ist. Die Floatglasscheiben 34 erzielen einen hohen Polarisator-Wirkungsgrad, während andererseits eine leichte Kühlbarkeit des Spiegelsandwiches aus Floatglasscheiben verwirklicht wird, weil diese unmittelbar aufeinander aufliegen und nicht durch isolierende Luftspalte zwischen den Glasscheiben voneinander getrennt sind. Die Floatglasscheiben stehen daher in wärmeleitenden Kontakt miteinander, so daß das Spiegelsandwich hinsichtlich der wärmeleitenden Eigenschaften als ein einstückiges Bauteil betrachtet werden kann.FIG. 6 shows part of the Brewster polarizer 33 in a sectional view. The Brewster polarizer 33 consists of a number (for example 5) of thin, plane-parallel, elliptical float glass panes 34 arranged one behind the other, which lie directly on one another, that is to say without forming a distance between them. The float glass panes 34 are enclosed in a glass carrier 35, which is shown in FIG. 6 only purely schematically. The float glass panes 34 achieve a high polarizer efficiency while, on the other hand, the mirror sandwich made of float glass panes is easy to cool because these lie directly on top of one another and are not separated from one another by insulating air gaps between the glass panes. The float glass panes are therefore in heat-conducting contact with one another, so that the mirror sandwich can be regarded as a one-piece component with regard to the heat-conducting properties.

Weiter wird durch das unmittelbare Aufliegen der Floatglasscheiben aufeinander erreicht, das Staubpartikel nicht zwischen die Glasscheiben gelangen können. Dadurch erhält der Brewster-Polarisator seinen hohen Wirkungsgrad auch nach einer langen Standzeit bei.Furthermore, the fact that the float glass panes lie directly on top of one another means that dust particles cannot get between the glass panes. As a result, the Brewster polarizer maintains its high efficiency even after a long service life.

Eine detailliertere Darstellung des Glassträgers, in welchen das Spiegelsandwich eingefaßt ist, ist den Figuren 7 bis 10 entnehmbar. Der Glasträger 35 weist die Form einer elliptischen Aufnahmewanne mit einem elliptischen Boden 39 und einer rings eines wesentlichen Teilbereichs des Bodens 39 verlaufende Wand 40 auf. Die Wand 40 ist mit einer Mehrzahl von Verriegelungsnasen 41 versehen, welche seitlich in das in denA more detailed representation of the glass carrier in which the mirror sandwich is enclosed can be seen in FIGS. 7 to 10. The glass carrier 35 has the shape of an elliptical receiving trough with an elliptical bottom 39 and a wall 40 running around a substantial partial area of the bottom 39. The wall 40 is provided with a plurality of locking lugs 41, which laterally into the in the

Figuren 7 bis 10 nicht dargestellte Spiegelsandwich eingreifen. Die Wand 40 muß sich nicht um den gesamten elliptischen Boden 39 herum erstrecken, so daß beispielsweise eine Montage des Spiegelsandwiches mit samt dem Glasträger 35 dicht an die Röhren 31, 32 möglich ist, ohne daß der Glasträger 35 an das Gehäuse 2 anstößt. Die Floatglasscheiben liegen daher unmittelbar auf der Schnittkantenfläche der Röhrenvorrichtung aus den Röhren 31 und 32 auf, welche im Brewster-Winkel geschnitten sind. Dabei sind die Floatglasscheiben 34 bzw. der Glasträger 35 mittels einer Dichtung zu der Schnittfläche ebenso wie ein Reflektor 36 und eine Lichtfilterplatte 37 zu den Röhren 31 und 32 abgedichtet, wie weiter unten noch erläutert wird. Dadurch wird der Innenraum der aus den Röhren 31 und 32 gebildeten Röhrenvorrichtung mechanisch abgedichtet, so daß kein Staub in diesen Innenraum eindringen kann. Am hinteren Ende der Röhre 31 ist eine Lampe 42, vorzugsweise eine Metall-Halogen-Lampe, mit einem Reflektor 36 angeordnet, der dicht an einer ringförmigen axialen Innenschulter der Röhre 31 angedrückt gehalten wird, wobei vorzugsweise zwischen der ringförmigen, axialen Innenschulter und dem Reflektor 36 eine nicht dargestellte Dichtung angeordnet ist.Figures 7 to 10 intervene mirror sandwich, not shown. The wall 40 does not have to extend around the entire elliptical base 39, so that, for example, an assembly of the mirror sandwich with the glass carrier 35 close to the tubes 31, 32 is possible without the glass carrier 35 abutting the housing 2. The float glass panes therefore lie directly on the cut edge surface of the tube device made of tubes 31 and 32, which are cut at a Brewster angle. The float glass panes 34 or the glass carrier 35 are sealed by means of a seal to the cut surface, as are a reflector 36 and a light filter plate 37 to the tubes 31 and 32, as will be explained further below. This will make the interior of the tubes 31 and 32 formed tube device mechanically sealed so that no dust can enter this interior. At the rear end of the tube 31 there is a lamp 42, preferably a metal-halogen lamp, with a reflector 36 which is held tightly pressed against an annular inner axial shoulder of the tube 31, preferably between the annular inner axial shoulder and the reflector 36 a seal, not shown, is arranged.

Die Lampe 42 strahlt sichtbares und infrarotes Licht axial nach vorn, wobei der Einfallswinkel auf den Brewster-Polarisator 33 57° ist. Die Lampe 42 ist so gestaltet, daß sie so gut wie kein ultraviolettes Licht ausstrahlt, welches hinsichtlich der Verbrennungsgefahr für die anwendende Person und der unerwünschten, punktuellen Bräunung vermieden werden muß. Die Lampenleistung ist etwa 20 W, aber darf keineswegs mehr als 80 bis 100 W sein, da die Kühlungsverhältnisse im wesentlichen unter dieser Grenzleistung optimal sind.The lamp 42 radiates visible and infrared light axially forward, the angle of incidence on the Brewster polarizer 33 being 57 °. The lamp 42 is designed in such a way that it emits virtually no ultraviolet light, which must be avoided with regard to the risk of burns for the user and the undesired, selective tanning. The lamp power is about 20 W, but must not be more than 80 to 100 W, since the cooling conditions are essentially optimal below this limit power.

Die Floatglasscheiben 34 des Brewster-Polarisators 33 reflektieren das Licht parallel zu der Achse der Röhre 32, wobei das reflektierte Licht linearpolarisiert ist. Die nicht reflektierten Lichtkomponenten treffen auf die schwarze innere Oberfläche der Verschlußplatte 35 und die entstehende Wärme wird von der Kühlluft abgeführt.The float glass panes 34 of the Brewster polarizer 33 reflect the light parallel to the axis of the tube 32, the reflected light being linearly polarized. The non-reflected light components hit the black inner surface of the closure plate 35 and the heat generated is dissipated by the cooling air.

Der Innenraum der Lichtquellenanordnung 3 ist an dem Vorderende der Röhre 32 mit einer gelben Lichtfilterplatte 37 verschlossen. Der Zweck der Lichtfilterplatte 37 ist einerseits das Herausfiltern von Spektralkomponenten unterhalb von etwa 400 bis 450 n aus den am Polarisator 33 reflektierten Lichtstrahlen und andererseits, wie bereits weiter oben angedeutet, das mechanische Verschließen des Innenraumes der Lichtquellenanordnung 3, damit die optischen Eigenschaften der hier angeordneten Elemente nicht durch Staubbildung beeinträchtigt werden.The interior of the light source arrangement 3 is closed at the front end of the tube 32 with a yellow light filter plate 37. The purpose of the light filter plate 37 is, on the one hand, to filter out spectral components below approximately 400 to 450 n from the light beams reflected at the polarizer 33 and, on the other hand, as already indicated above, to mechanically close the interior of the light source arrangement 3, so that the optical properties of those arranged here Elements are not affected by dust formation.

Seitlich im Kühlluftstrom unterhalb der Lampe 42 ist eine Montageplatte 38 angeordnet, die von mehreren, in der Zeichnung nicht dargestellten Stützelementen des Gehäuses 2 gehalten wird. Die elektrische Anschlußleitung führt bis zur Montageplatte 38, die auch eine Sicherung sowie einige elektrische Bauelemente trägt. Es ist zweckmäßig, wenn ein elektrisches Dämpfungsglied mit der Lampe 42 in Reihe geschaltet ist, damit die Lampe 42 zu etwa 2 bis 5 % unterhitzt wird. Eine Unterhitzung der Lampe 42 erhöht einerseits deren Lebensdauer und verschiebt andererseits die spektrale Verteilung des ausgestrahlten Lichtes in Richtung zu dem infraroten Bereich (durch Verminderung der effektiven Lichttemperatur), wodurch die Eindringungstiefe der Strahlen erhöht wird. Es ist auch möglich, daß eine derartige spektrale Verteilung für die Biostimulation günstiger ist. Die Verminderung der Lichttemperatur vermindert auch dieLaterally in the cooling air flow below the lamp 42 is one Mounting plate 38 is arranged, which is held by a plurality of support elements of the housing 2, not shown in the drawing. The electrical connection line leads to the mounting plate 38, which also carries a fuse and some electrical components. It is expedient if an electrical attenuator is connected in series with the lamp 42, so that the lamp 42 is underheated to about 2 to 5%. Overheating the lamp 42 on the one hand increases its lifespan and on the other hand shifts the spectral distribution of the emitted light in the direction of the infrared region (by reducing the effective light temperature), which increases the depth of penetration of the rays. It is also possible that such a spectral distribution is more favorable for biostimulation. The decrease in light temperature also reduces the

Leistungsaufnahme. Das Unterhitzen der Lampe 42 kann auch durch Verminderung der Speisespannung erreicht werden. Wenn die Nennspannung der Lampe z.B. 12 V ist, kann der die Lampe speisende Transformator zur Lieferung von etwa 11 - 11,4 V ausgelegt werden.Power consumption. The underheating of the lamp 42 can also be achieved by reducing the supply voltage. If the nominal voltage of the lamp e.g. Is 12 V, the transformer that feeds the lamp can be designed to deliver around 11 - 11.4 V.

Der Ventilator 4 ist in Axialrichtung im Handgriff 21 axial entgegengesetzt zur Lampe 42 hin ausgerichtet und saugt die Luft in den Gehäuseinnenraum durch die rings der Lichtquellenanordnung 3 ausgebildete Eintrittsöffnung 24 (Figur 3) in das Gehäuse ein. Das Ausströmen erfolgt über Schlitze 25 (Figuren 1 und 4) am freien Ende des Handgriffes 21. Die Kühlluft strömt in dem Gehäuseinnenraum entlang der ganzen Mantelfläche der Lichtquellenanordnung 3. In Figur 1 ist diese Strömung durch Pfeile veranschaulicht.The fan 4 is oriented axially in the handle 21 axially opposite to the lamp 42 and sucks the air into the housing interior through the inlet opening 24 (FIG. 3) formed around the light source arrangement 3 into the housing. The outflow takes place via slots 25 (FIGS. 1 and 4) at the free end of the handle 21. The cooling air flows in the housing interior along the entire lateral surface of the light source arrangement 3. This flow is illustrated by arrows in FIG.

Die in der Zeichnung dargestellte Form des Gehäuses ist nicht nur ästhetisch wohlgefällig, sondern sie führt auch zu einer sehr günstigen Kühlung. Hinter der Verschlußplatte 33 und im Bereich des oberen Endes der Röhre 31 ist das Volumen desThe shape of the housing shown in the drawing is not only aesthetically pleasing, but it also leads to very cheap cooling. Behind the closure plate 33 and in the region of the upper end of the tube 31 is the volume of the

Gehäuseinnenraums wegen der Wölbung des Gehäusemittelteiles 22 am größten und die Strömungsgeschwindigkeit ist ausreichend, die Wärme von der großen Oberfläche der Verschlußplatte 33 abzuführen; anschließend vermindert sich der Innenraum im Bereich der Lampe 35, wodurch die Luftgeschwindigkeit wesentlich erhöht wird. In diesem Kanal 26 strömt die Luft schnell über die parabolförmige Oberfläche des Reflektors 36 mit der Lampe 42, wodurch hier eine intensive Kühlung stattfindet und die Betriebstemperatur der Lampe 42 die zugelassenen Werte nicht überschreitet. Die Temperatur des Gehäuses wird auch nach langem Betrieb der Lampe nicht mehr als um 20 °C höher als die Umgebungstemperatur.Interior due to the curvature of the housing middle part 22 and the flow rate is sufficient, the heat from the large surface of the closure plate 33rd dissipate; the interior space in the area of the lamp 35 then decreases, as a result of which the air speed is significantly increased. In this channel 26, the air flows quickly over the parabolic surface of the reflector 36 with the lamp 42, as a result of which intensive cooling takes place here and the operating temperature of the lamp 42 does not exceed the permitted values. The temperature of the housing does not become more than 20 ° C higher than the ambient temperature even after the lamp has been in operation for a long time.

Die Achse des Handgriffes 21 steht ein wenig schräg zur Lampenachse und zwar derart, daß die Richtung der aus der Behandlungsleuchte 1 austretenden Lichtstrahlen in einem Winkel zwischen 105 bis 120°, vorzugsweise 105 bis 110° zur Handgriffachse austreten. Diese Ausrichtung ermöglicht eine sehr angenehme Haltung und eine bequeme Lichtbehandlung.The axis of the handle 21 is a little oblique to the lamp axis and in such a way that the direction of the light rays emerging from the treatment lamp 1 emerge at an angle between 105 to 120 °, preferably 105 to 110 ° to the handle axis. This orientation enables a very pleasant posture and a comfortable light treatment.

Im Falle einer Metall-Halogen-Lampe mit 20 W Leistung und einem Reflektordurchmesser von 50 mm wird der innere Durchmesser der Röhren 31, 32 ebenfalls zu 50 mm gewählt. DieseIn the case of a metal-halogen lamp with a power of 20 W and a reflector diameter of 50 mm, the inner diameter of the tubes 31, 32 is also chosen to be 50 mm. This

Behandlungslampe strahlt paralleles, polarisiertes Licht in einem kreisförmigen Bündel mit 50 mm Durchmesser aus und die Licht-Leistungsdichte beträgt etwa 50 mW/cm2. The treatment lamp emits parallel, polarized light in a circular bundle with a diameter of 50 mm and the light power density is approximately 50 mW / cm 2 .
