Description

Die Erfindung bezieht sich auf eine Leuchte nach dem Oberbegriff des Anspruches 1 oder 8.The invention relates to a lamp according to the preamble of claim 1 or 8.

Es gibt Leuchten, die so ausgestaltet sind, daß sie das Licht mit einer verhältnismäßig geringen Streuung abstrahlen. Solche Leuchten sind deshalb dazu geeignet, relativ kleine Flächen relativ hell auszuleuchten. Da solche Leuchten in den meisten Fällen in vertikaler Position mit nach unten gerichteter Abstrahlung angeordnet werden, werden sie in der Fachsprache allgemein mit "Downlights" bezeichnet.There are lights that are designed so that they are light with a relative emit little scatter. Such lights are therefore suitable, relatively illuminate small areas relatively brightly. Since such lights in most cases vertical position with the radiation directed downwards generally referred to in technical terms as "downlights".

Ein Downlight strahlt das Licht überwiegend steil nach unten ab, so daß oberhalb eines Winkels von zumindest 30° bezüglich der Horizontalen kein Licht die Leuchte verläßt, oder kaum Licht die Leuchte verläßt. Dadurch wird für Personen im beleuchteten Raum eine direkte Blendung durch die meist sehr hellen Lampen vermieden.A downlight mainly emits the light steeply downwards, so that above one No light leaves the luminaire at an angle of at least 30 ° with respect to the horizontal, or hardly any light leaves the lamp. This is for people in the illuminated room direct glare from the mostly very bright lamps avoided.

Wird eine solche Leuchte in der Nähe einer Wand montiert, so bleibt der obere Teil der Wand aufgrund der Entblendung dunkel, während der untere Teil der Wand angestrahlt wird bzw. ein entsprechender Bereich des Raumes beleuchtet wird. Um diesen Effekt zu vermeiden und die ganze Wand oder den gesamten Höhenbereich etwa gleichmäßig aufzuhellen, ist es bereits vorgeschlagen worden, in eine solche Leuchte auf der der Wand oder dem vorgenannten Bereich gegenüberliegenden Seite einen Zusatzreflektor, nämlich einen sog. Wandfluter-Reflektor - einzubauen. Bei einem solchen Einbau sind zwei Ausführungen möglich.If such a lamp is installed near a wall, the upper part of the remains Wall darkened due to glare control, while the lower part of the wall was illuminated a corresponding area of the room is illuminated. To this effect to avoid and the whole wall or the entire height range about evenly to brighten, it has already been proposed, in such a lamp on the An additional reflector on the wall or the side opposite the aforementioned area, namely a so-called wall washer reflector - to be installed. With such an installation two versions possible.

Bei einer ersten, in der beigefügten Fig. 1 dargestellten Ausführung läßt sich der Zusatzreflektor B innerhalb des Hauptreflektors A der Leuchte C montieren. Dadurch wird der freie Querschnitt der Lichtaustrittsöffnung D reduziert, was einerseits zu einer Verringerung des Wirkungsgrades führt. Andererseits ist der verkleinerte freie Querschnitt mit einem vom normalen Erscheinungsbild unterschiedlichen Erscheinungsbild verbunden, was zur subjektiven Störung des Raumempfindens führen kann. D.h. das Aussehen der Leuchte wird verschlechtert. Eine solche Leuchte ist auch aus der US 4,475,147 zu entnehmen.In a first, shown in the accompanying Fig. 1, the Mount the additional reflector B inside the main reflector A of lamp C. Thereby the free cross section of the light exit opening D is reduced, which on the one hand leads to a Reduction in efficiency leads. On the other hand, the downsized is free Cross section with a different from the normal appearance Appearance linked, which lead to the subjective disturbance of the sense of space can. That the appearance of the lamp is deteriorated. Such a lamp is also from US 4,475,147.

Bei einer zweiten, in Fig. 2 dargestellten Ausführung ist der Hauptreflektor A in dem der zu beleuchtenden Wand oder dem zu beleuchtenden Bereich gegenüberliegenden Bereich ausgeschnitten, wobei der Zusatzreflektor B im Bereich des Ausschnitts E außerhalb des Hauptreflektors A montiert ist. Durch die Ausschnittsöffnung E im Hauptreflektor wird dieser mechanisch geschwächt. Außerdem ist hierdurch ein zusätzlicher Bearbeitungsschritt notwendig, was zu einer beträchtlichen Vergrößerung des Herstellungsaufwandes führt. Eine solche Leuchte ist von der eingangs angegebenen gattungsgemäßen Art und auch aus der DE 87 09 038 U zu entnehmen.In a second embodiment, shown in FIG. 2, the main reflector A is in the the wall to be illuminated or the area opposite to be illuminated Cut out the area, with the additional reflector B in the area of the cutout E is mounted outside the main reflector A. Through the opening E in the The main reflector is mechanically weakened. It also makes a additional processing step necessary, resulting in a considerable enlargement of the manufacturing costs. Such a lamp is of the type specified at the beginning generic type and also from DE 87 09 038 U.

In der FR 2 192 272 ist eine Leuchte mit einem wenigstens teilweise aus Kunststoff bestehenden Reflektorkörper beschrieben, der innenseitig oder außenseitig mit einer Reflexionsschicht beschichtet ist.In FR 2 192 272 there is a lamp with an at least partially made of plastic existing reflector body described, the inside or outside with a Reflective layer is coated.

Aus der US 5 535 110 A ist eine Leuchte mit einem domförmigen Hauptreflektor und einem Zusatzreflektor zur seitlichen Abstrahlung eines Teils des Lichtes der Lampe beschrieben. Der Zusatzreflektor besteht aus einer Kunststoffschicht, die im zugehörigen Bereich der Leuchte an der Innenseite des Hauptreflektors angeordnet ist und auf ihrer Innenseite in Umfangsrichtung verlaufende Stufenflächen aufweist, die das Licht zur betreffenden Seite hin reflektieren. From US 5 535 110 A is a lamp with a dome-shaped main reflector and an additional reflector for the lateral emission of part of the light from the lamp described. The additional reflector consists of a plastic layer, which in the associated area of the lamp is arranged on the inside of the main reflector and has circumferential step surfaces on the inside thereof reflect the light towards the relevant side.

Der Erfindung liegt die Aufgabe zugrunde, eine Leuchte der vorliegenden Art so auszugestalten, daß wenigstens ein seitlicher Teilbereich der Umgebung der Leuchte ohne Stabilitätsverlust anstrahlbar ist.The invention has for its object a lamp of the present type to design that at least a partial portion of the area surrounding the lamp can be illuminated without loss of stability.

Diese Aufgabe wird durch die Merkmale des Anspruches 1 oder 8 gelöst.This object is solved by the features of claim 1 or 8.

Bei beiden erfindungsgemäßen Ausgestaltungen bedarf es keines Ausschnitts im Hauptreflektor im Bereich des Zusatzreflektors. Die Bestrahlung des Zusatzreflektors erfolgt durch das Material des Hauptreflektors hindurch. Hierdurch wird der Herstellungsaufwand wesentlich geringer und außerdem der Hauptreflektor nicht geschwächt. Außerdem wird eine einfache und kostengünstig herstellbare Bauweise erreicht.In both configurations according to the invention, no detail in the Main reflector in the area of the additional reflector. Irradiation of the additional reflector takes place through the material of the main reflector. This will Manufacturing costs much lower and also the main reflector is not weakened. In addition, a simple and inexpensive to manufacture construction reached.

Bei der erfindungsgemäßen Ausgestaltung ist der Hauptreflektor vorzugsweise für die Abstrahlung eines schmalen Strahlenbündels eingerichtet.In the embodiment according to the invention, the main reflector is preferably for the Radiation of a narrow beam set up.

Die Reflexionsschicht kann wahlweise außenseitig oder innenseitig am Hauptreflektor angeordnet sein. Dies ist insbesondere dann vorteilhaft, wenn der transparente Hauptreflektorkörper außenseitig eine Licht streuende Struktur, z. B. Facetten, aufweist. Wird nun auf den Hauptreflektor außenseitig die Reflexionsschicht aufgetragen, so kommt diese streuende Struktur zur Wirkung. Wird hingegen die Reflexionsschicht auf der glatten Innenseite des Hauptreflektors aufgebracht, so entsteht ein einfacher Reflektor mit glatter Reflexionsschicht. Die streuende Struktur ist in diesem Fall wirkungslos, allerdings lassen sich mit einem einzigen Werkzeug für den transparenten Grundkörper zwei Reflektortypen (glatt oder strukturiert) realisieren.The reflection layer can either be on the outside or on the inside of the main reflector be arranged. This is particularly advantageous if the transparent Main reflector body on the outside a light scattering structure, e.g. B. facets, having. Now the reflection layer is on the outside of the main reflector applied, this scattering structure comes into effect. However, if Reflection layer applied to the smooth inside of the main reflector, this creates a simple reflector with a smooth reflective layer. The scattering structure is in in this case ineffective, but with a single tool for the transparent base body two reflector types (smooth or structured).

Die Reflexionsschicht läßt sich in einfacher und kostengünstiger Weise auftragen, wobei sich eine gute Qualität erreichen läßt. The reflection layer can be applied in a simple and inexpensive manner, with good quality can be achieved.

In den Unteransprüchen sind Merkmale enthalten, die eine gezielte Beleuchtung wenigstens eines seitlichen Bereichs verbessern, zur einfachen, kleinen und kostengünstig herstellbaren Bauweise führen und außerdem die Reflexion verbessern.The subclaims contain features that provide targeted lighting improve at least one side area, for simple, small and lead to inexpensive to manufacture construction and also improve the reflection.

The panel 7 can consist of individual frame parts exist or be in one piece in the circumferential direction. It can do it or its parts be integrally formed with the housing 4 or the associated frame pieces 6 or attached to these parts.

Vorzugsweise weist der Hauptreflektor 5 an seinem unteren Rand einen nach außen ragenden Flansch 12 auf, der in einer Ringausnehmung 13 im Blendenrahmen wenigstens teilweise versenkt aufgenommen ist und insbesondere so tief versenkt angeordnet ist, daß die Vorder- bzw. Unterseite des Flansches 12 mit der Vorder- bzw. Unterseite des Blendenrahmens in etwa abschließt. Dabei kann der Flansch 12 an einer den Grund der Ringausnehmung 13 bildenden Schulterfläche 14 anliegen.The main reflector 5 preferably has an outward at its lower edge projecting flange 12, in an annular recess 13 in the diaphragm frame is at least partially sunk and in particular sunk so deep it is arranged that the front or underside of the flange 12 with the front or Bottom of the bezel frame approximately closes. The flange 12 can on a the shoulder surface 14 forming the base of the ring recess 13 abuts.

Der Hauptreflektor 5 weist eine kuppelförmige Querschnittsform auf, wobei er vorzugsweise einteilig geformt ist. Im Firstbereich ist die Querschnittsform des Hauptreflektors 5 flach oder kegel- oder kugelabschnittsförmig radial nach außen geneigt geformt. An diese Firstwandung 15 schließt sich eine Rundung 16 nach unten an, die in eine divergente Seitenwandung 17 übergeht, die kegel- oder kugelringzonenförmig geformt sein kann. Der Winkel W den die Seitenwandung 17 mit der vertikalen Mittelachse 18 einschließt, ist verhältnismäßig spitz und beträgt etwa 5 bis 15°, insbesondere etwa 10°. D.h., die Seitenwandung 17 ist verhältnismäßig steil angeordnet.The main reflector 5 has a dome-shaped cross-sectional shape, whereby it is preferably formed in one piece. The cross-sectional shape of the Main reflector 5 flat or conical or spherical segment-shaped radially outwards shaped inclined. At this ridge wall 15 there is a curve 16 at the bottom on, which merges into a divergent side wall 17, the conical or can be shaped like a spherical ring. The angle W with the side wall 17 of the vertical central axis 18 is relatively pointed and is approximately 5 up to 15 °, in particular about 10 °. That is, the side wall 17 is relatively steep arranged.

Die Lampe 2 erstreckt sich durch eine Durchführungsöffnung 19 in den oberen Bereich des Hauptreflektors 5 und ist in dieser Position mittels einer geeigneten Fassung 21 gehalten, die am Gehäuse 4 oder an einem zugehörigen Rahmenstück 6 befestigt sein kann. Bei der vorliegenden Ausgestaltung sind die Durchführungsöffnung 19 und die Fassung 21 im oberen seitlichen Bereich der Leuchte 1 angeordnet. The lamp 2 extends through a feed-through opening 19 into the upper region of the main reflector 5 and is in this position by means of a suitable socket 21 held, which are attached to the housing 4 or to an associated frame piece 6 can. In the present embodiment, the through opening 19 and the Version 21 arranged in the upper side area of the lamp 1.

Der Hauptreflektor 5 ist in seinem Firstbereich durch geeignete Haltemittel, z.B. Klemmen oder Schrauben am Gehäuse 4 oder an einem zugehörigen Rahmenstück 6 gehalten. Der Grundkörper des Hauptreflektors 5 besteht aus einem transparenten Material wie Glas oder Kunststoff, wobei die Dicke der Umfangswand 22 gleich sein kann, wie es Fig. 3 zeigt. Außenseitig ist die Umfangswand 22 mit einer Reflektionsschicht 23 beschichtet, die eine an der Außenseite des Hauptreflektors 5 befindliche Refektionsfläche 24 bildet, an der die von der Lampe 2 ausgehenden Lichtstrahlen 25 reflektiert werden. Wie insbesondere aus Fig. 4 zu entnehmen ist, werden die Lichtstrahlen 25 beim Durchdringen der Innenfläche 26 zunächst zu der Lichtausbreitungsrichtung 27 entgegengesetzter Seite hin und beim Austritt aus der Innenfläche 26 zur Ausbreitungsrichtung 27 hin gebrochen. Je nach Einfallswinkel bezüglich der Innenfläche 26 und der Reflektionsfläche 24 ergeben sich dabei von der Darstellung in Fig. 4 unterschiedliche Lichtstrahlenrichtungen.The main reflector 5 is in its ridge area by suitable holding means, e.g. Clamps or screws on the housing 4 or on an associated frame piece 6 held. The main body of the main reflector 5 consists of a transparent Material such as glass or plastic, the thickness of the peripheral wall 22 being the same can, as shown in Fig. 3. On the outside, the peripheral wall 22 has a Reflective layer 23 coated, one on the outside of the main reflector 5th located refection surface 24 forms on which the outgoing from the lamp 2 Light rays 25 are reflected. As can be seen in particular from FIG. 4, the light rays 25 when penetrating the inner surface 26 first to the Light propagation direction 27 opposite side and when exiting the Inner surface 26 broken towards the direction of propagation 27. Depending on the angle of incidence with respect to the inner surface 26 and the reflection surface 24 result from the Representation in Fig. 4 different light beam directions.

Wie aus Fig. 4 zu entnehmen ist, ist die unterseitige Flanschfläche 12a, die vorzugsweise noch oben kegelförmig konvergent ausgebildet ist, mit der Reflexionsschicht 23 beschichtet.As can be seen from FIG. 4, the underside flange surface 12a is the is preferably still conically shaped at the top with which Reflective layer 23 coated.

Bei der Ausgestaltung gemäß Fig. 5, bei der gleiche oder vergleichbare Teile mit gleichen Bezugszeichen versehen sind, ist der Leuchte ein Zusatzreflektor 31 zugeordnet, der im unteren Bereich des Hauptreflektors 5 angeordnet ist oder sich von diesem nach unten anschließt und sich über den gesamten Umfang oder nur über einen Teilbereich des Umfanges erstrecken kann.5, with the same or comparable parts with are provided with the same reference numerals, the luminaire is an additional reflector 31 assigned, which is arranged in the lower region of the main reflector 5 or from this adjoins downwards and extends over the entire scope or only over one Part of the circumference can extend.

Es ist der Zweck eines solchen Zusatzreflektors 31, die verhältnismäßig steil abstrahlende Leuchte 1 so zu verändern, daß zumindest auf wenigstens einem Teilbereich auch eine seitliche Abstrahlung und Ausleuchtung einer seitlichen Wand im vorhandenen Raum oder des seitlichen Bereichs des vorhandenen Raumes möglich ist. Diese zusätzliche und seitliche Ausbreitungsrichtung ist mit 32 bezeichnet.It is the purpose of such an additional reflector 31 that is relatively steep to change emitting lamp 1 so that at least on at least one Partial area also a side radiation and illumination of a side wall in the existing space or the lateral area of the existing space is possible. This additional and lateral direction of propagation is designated 32.

Bei der Ausgestaltung gemäß Fig. 5 ist der Zusatzreflektor 31 aussenseitig vom Hauptreflektor 5 angeordnet, wobei er einen nach außen gerichteten Abstand von letzterem aufweist. Der Zusatzreflektor 31 ist zur Innenseite hin in der Vertikalen konkav, insbesondere gerundet konkav geformt und in der Horizontalen vorzugsweise etwa an die Umfangsform des Hauptreflektors 5 angepaßt. Wie aus Fig. 5 zu entnehmen ist, schließen der obere und der untere Bereich der innenseitig angeordneten Reflektionsfläche 33 des Zusatzreflektors 31 mit der Vertikalen Winkel W1, W2 ein, die in etwa gleich groß sind. Hierdurch ergibt sich eine günstige resultierende seitliche Ausbreitungsrichtung 32, die sich unter dem gegenüberliegenden unteren Rand des Zusatzreflektors 5 erstreckt.5, the additional reflector 31 is on the outside of Main reflector 5 arranged, being an outward distance of the latter has. The additional reflector 31 is vertical to the inside concave, in particular rounded concave and preferred in the horizontal adapted approximately to the circumferential shape of the main reflector 5. As shown in Fig. 5 remove, close the upper and lower areas of the inside Reflection surface 33 of the additional reflector 31 with the vertical angle W1, W2, which are about the same size. This results in a favorable resulting lateral Direction of propagation 32, which is located under the opposite lower edge of the Additional reflector 5 extends.

Bei der Ausgestaltung nach Fig. 5 kann die Reflexionsschicht 23 an der Außenseite oder vorzugsweise an der Innenseite 26 des Hauptreflektors 5 angeordnet sein.5, the reflection layer 23 can be on the outside or preferably be arranged on the inside 26 of the main reflector 5.

Im Bereich des Zusatzreflektors 31 befindet sich am Hauptreflektor 5 keine Reflektionsschicht 23. Das so gebildete Fenster 34 ist in seinen Abmessungen etwa gleich oder größer bemessen als die entsprechenden Abmessungen des Zusatzreflektors 31, so daß eine erforderliche Menge Lichtstrahlen durch die im Bereich des Fensters 34 transparente Umfangswand 22 des Hauptreflektors 5 gegen den Zusatzreflektor 31 gelangen und an dessen Reflexionsfläche 33 in die Ausbreitungsrichtung 32 reflektiert werden.In the area of the additional reflector 31 there is none on the main reflector 5 Reflective layer 23. The dimensions of the window 34 formed in this way are approximately dimensioned equal or larger than the corresponding dimensions of the additional reflector 31, so that a required amount of light rays through the area of the window 34th transparent peripheral wall 22 of the main reflector 5 against the additional reflector 31 arrive and reflected on the reflection surface 33 in the direction of propagation 32 become.

Aus Fig. 5 ist deutlich zu entnehmen, daß die Reflexionsflächen 24, 33 zumindest im unteren bis mittleren Bereich des Zusatzreflektors 31 bezüglich der Mittelachse 18 nach oben divergieren.From Fig. 5 it can clearly be seen that the reflection surfaces 24, 33 at least in lower to middle region of the additional reflector 31 with respect to the central axis 18 diverge above.

Das Fenster 34 läßt sich in einfacher Weise erzeugen, z.B. durch Abdeckung der Innenund/oder Außenfläche des Hauptreflektors 5 bei dessen außen- oder innenseitiger Beschichtung mit der Reflexionsschicht 23. Diese besteht vorzugsweise aus einem metallischen Material. Die Reflexionsschicht 23 kann durch Bedampfen des Hauptreflektors 5 mit Aluminium oder durch Chromatieren aufgebracht sein.The window 34 can be easily created, e.g. by covering the inside and / or Outer surface of the main reflector 5 on the outside or inside Coating with the reflection layer 23. This preferably consists of a metallic material. The reflection layer 23 can by vapor deposition Main reflector 5 can be applied with aluminum or by chromating.

Zum Beschichten eignen sich gut auch an sich bekannte VakuumBeschichtungsverfahren mit Bedampfung, galvanische Beschichtungsverfahren und chemische Spritzverfahren zur Metallisierung von Werkstoffen.Vacuum coating methods known per se are also well suited for coating with vapor deposition, electroplating and chemical spraying processes for the metallization of materials.

Bei der Ausgestaltung gemäß Fig. 6, bei der gleiche oder vergleichbare Teile mit gleichen Bezugszeichen versehen sind, ist im Gegensatz zur vorbeschriebenen Ausgestaltung der Zusatzreflektor 31 nicht in einem nach außen gerichteten Abstand vom Hauptreflektor 5 angeordnet, sondern direkt an der Außenseite des Hauptreflektors 5 angeordnet, wobei die Außenseite nach außen in der Vertikalen konvex ausgeformt ist. Dieser Zusatzreflektor 31 ist somit einstückig am Hauptreflektor 5 angeordnet. Die Reflexionsfläche 33 ist durch eine außenseitig im Bereich des Fensters 34 und im Bereich der Ausformung 35 aufgebrachte Reflexionsschicht 23a gebildet. Bei dieser Ausgestaltung wird der Zusatzreflektor 31 somit durch eine transparente Verdickung 30 bzw. einen außenseitigen transparenten Materialansatz am Hauptreflektor 5 gebildet. Auch bei dieser Ausgestaltung kann die Reflexionsfläche 24 durch eine außenseitige oder vorzugsweise innenseitige Beschichtung des Hauptreflektors 5 mit einer Reflexionsschicht 23 gebildet sein. Im horizontalen Querschnitt kann die Außenfläche 30a der Verdickung 30 oder eines Materialansatzes parallel zur geraden oder gekrümmten Umfangswand 22 verlaufen. Dabei können die in Umfangsrichtung weisenden Enden der Verdickung 30 stumpf, z. B. eckig oder ebenfalls gerundet sein. Es ist auch vorteilhaft, sowohl bei einer geraden als auch gekrümmten Umfangswand 22 die Außenfläche 30a konvex gekrümmt bzw. mit einer stärkeren konvexen Krümmung auszubilden als die Krümmung der Umfangswand 22, wodurch sich eine linsenförmige Querschnittsform für die Verdickung 30 ergibt.6, with the same or comparable parts the same reference numerals is in contrast to the above Design of the additional reflector 31 not at an outward distance arranged by the main reflector 5, but directly on the outside of the main reflector 5 arranged, the outer side being convex in the vertical direction is. This additional reflector 31 is thus arranged in one piece on the main reflector 5. The Reflection surface 33 is by an outside in the area of the window 34 and in Area of the formation 35 applied reflection layer 23a formed. At this The additional reflector 31 is thus embodied by a transparent thickening 30 or an outside transparent material approach on the main reflector 5 is formed. In this embodiment too, the reflection surface 24 can be covered by an outside or preferably inside coating of the main reflector 5 with a Reflection layer 23 may be formed. In the horizontal cross section, the outer surface 30a of the thickening 30 or a material approach parallel to the straight or curved peripheral wall 22 extend. The can in the circumferential direction pointing ends of the thickening 30 blunt, z. B. be angular or rounded. It is also advantageous for both a straight and curved peripheral wall 22 the outer surface 30a is convexly curved or with a stronger convex Form curvature than the curvature of the peripheral wall 22, whereby a lens-shaped cross-sectional shape for the thickening 30 results.

Bei der Ausgestaltung gemäß Fig. 6 schließt die Reflexionsfläche 33 in ihrem oberen Bereich einen nach unten offenen spitzen Winkel W3 mit der Umfangswand 22 des Hauptreflektors 5 ein. Dies sind nur vorteilhafte beispielhafte Ausgestaltungen.

Zwischen den einander folgenden Reflexionsflächenstreifen 33a sind quer zu letzteren angeordnete Stufenflächen 33b angeordnet, die eine stufenförmige Außenfläche des Zusatzreflektors 31 ergeben. Wenigstens die Reflexionsflächenstreifen 33a und vorzugsweise auch die Stufenflächen 33b sind mit einer Reflexionsschicht 23 beschichtet, so daß die Reflexion entsprechend den Ausbreitungsrichtungskomponenten 32 gewährleistet ist. Auch bei dieser Ausgestaltung kann die Reflexionsschicht 23 außerhalb des Fensters 34 an der Außenseite oder vorzugsweise Innenseite 26 des Hauptreflektors 5 angeordnet sein. The configuration according to FIGS. 8 and 9 differs from the configuration according to 6 and 7 in that the reflection surface 33 in superimposed Reflective surface stripe 33a is divided with respect to a resultant one Irradiation direction 27 and the vertical longitudinal central axis 18 of the lamp 2 in one such angles W4 are arranged that - taking into account the Light refraction angle - the respective propagation direction component 32 below the opposite edge region of the main reflector 5 is directed. Between the successive reflective surface strips 33a are transverse to the latter arranged step surfaces 33b, which has a step-shaped outer surface of the Additional reflector 31 result. At least the reflective surface strips 33a and preferably also the step surfaces 33b are provided with a reflection layer 23 coated so that the reflection corresponds to the propagation direction components 32 is guaranteed.
