Description
Die Erfindung betrifft eine Reflektorleuchte entsprechend dem Oberbegriff des Anspruchs 1. Eine solche Reflektorleuchte ist hinsichtlich ihrer allgemeinen lichttechnischen Eigenschaften beispielsweise im "Handbuch für Beleuchtung", 4. Aufl., Verlag W. Girardet, Essen (s. dort Seite 107) beschrieben. Charakteristisch für eine derartige Leuchte mit Parabolreflektor ist es, dass paralleles Licht aus dem Reflektor austritt, wenn sich die Lichtquelle im Brennpunkt befindet.The invention relates to a reflector lamp according to the preamble of claim 1. Such a reflector lamp is in terms of their general lighting properties, for example in the "Manual for Lighting ", 4th edition, published by W. Girardet, Essen (see page 107 there). It is characteristic of such a lamp with a parabolic reflector that parallel light emerges from the reflector when the light source is in focus located.
Als Bodeneinbauleuchten dienende Reflektorleuchten weisen in der Regel einen sehr flachen Parabolreflektor auf, was allerdings zur Folge hat, dass eine solche Reflektorleuchte bei Einblick von oben erheblich blendet. Die Blendung kann indessen durch Abschirmung der Lichtquelle mittels einer Kalotte vermieden werden, welche einen direkten Einblick z.B. auf die Lampenwendel verhindert.Reflector lights serving as recessed floor lights point in the Usually set up a very flat parabolic reflector, which however results in that such a reflector lamp is considerably dazzling when viewed from above. The Glare can, however, be achieved by shielding the light source using a Calotte can be avoided, which gives a direct insight e.g. on the lamp filament prevented.
Von einer einen Konusreflektor aufweisenden Aufbau-Reflektorleuchte ist es bekannt (s. Katalog "ERCO Leuchtenprogramm", Ausgabe 1993/95, Seite 55), innerhalb eines sich rückwärtig an einen Konusreflektor anschließenden Kaschierrohres eine Fassungsarmatur mitsamt einer Allgebrauchslampe zur Änderung des geometrischen Schattenraums axial zu verschieben.From a surface-mounted reflector luminaire with a cone reflector it is known (see catalog "ERCO luminaire range", edition 1993/95, page 55), within one that adjoins a cone reflector at the rear Kaschierrohres a lampholder with an all-purpose lamp for Axially shift the change of the geometric shadow space.
Ausgehend von der eingangs beschriebenen bekannten Reflektorleuchte gemäß dem "Handbuch für Beleuchtung" (s. a.a.O.), liegt der Erfindung die Aufgabe zugrunde, insbesondere eine Boden-, Decken- oder Wandeinbau-Reflektorleuchte zu schaffen, welche eine kompakte, insbesondere flache Bauweise aufweist und welche trotz ihrer flachen Bauweise eine im wesentlichen blendfreie Beleuchtung gestattet. Starting from the known reflector lamp described above According to the "Handbook for lighting" (see above), the invention lies Task based, in particular a floor, ceiling or recessed wall reflector lamp to create a compact, especially flat design and which, despite its flat design, is essentially one Glare-free lighting allowed.
In Verbindung mit den Merkmalen des Oberbegriffs des Anspruchs 1 wird diese Aufgabe entsprechend der Erfindung dadurch gelöst, dass der Parabolreflektor im wesentlichen nur zwischen seinem Scheitel und einer durch seinen Brennpunkt gelegten, die Symmetrieachse des Parabolreflektors senkrecht schneidenden Lichtaustrittsebene lichtleitend wirksam ist, dass das von der Lichtquelle ausgehende Licht nur zwischen der Lichtaustrittsebene und dem Scheitel zum Reflektor hin abstrahlt, und dass die Lichtquelle in der Lichtaustrittsebene bezüglich des Brennpunkts translatorisch verschiebbar oder translatorisch verschoben angeordnet ist.In connection with the features of the preamble of claim 1 This object is achieved according to the invention in that the parabolic reflector essentially only between its apex and one through its Focal point, the axis of symmetry of the parabolic reflector perpendicular intersecting light exit plane that is effective from the Light outgoing light only between the light exit plane and the Apex radiates towards the reflector, and that the light source in the light exit plane displaceable or translational with respect to the focal point is shifted.
Wesentlich ist, dass die Erfindung eine axial verkürzte Bauform des Parabolreflektors gestattet. Dadurch nämlich, dass der Parabolreflektor im wesentlichen nur zwischen seinem Scheitel und einer durch den Brennpunkt gelegten, die Symmetrieachse des Parabolreflektors senkrecht schneidenden Lichtaustrittsebene lichtleitend wirksam ist, kann der Parabolreflektor entweder um den außerhalb der Lichtaustrittsebene befindlichen lichttechnisch unwirksamen Reflektorbereich gekürzt oder der unwirksame äußere Reflektorbereich zu gestalterischen Zwecken verwandt werden, um beispielsweise einen ansprechenden Übergang zum Leuchtengehäuse zu schaffen. Im übrigen wird durch den gewissermaßen axial gekürzten erfindungsgemäßen Parabolreflektor im Vergleich zu einem axial ungekürzten Parabolreflektor eine enge Lichtführung, verbunden mit einer relativ großen Lichtstromdichte im Sinne einer Richtwirkung des abgestrahlten Lichts, erreicht.It is essential that the invention has an axially shortened design of the Parabolic reflector allowed. Because the parabolic reflector in essential only between its apex and one through the focal point placed, perpendicularly intersecting the axis of symmetry of the parabolic reflector The parabolic reflector can either act as a light guide around the lighting technically ineffective located outside the light exit plane Shortened reflector area or the ineffective outer reflector area be used for design purposes, for example a to create an appealing transition to the luminaire housing. Otherwise through the axially shortened parabolic reflector according to the invention in comparison to an axially uncut parabolic reflector, a narrow light guide, combined with a relatively high luminous flux density in the sense of a directional effect of the emitted light.
Dadurch, dass die elektrische Lichtquelle bzw. das elektrische Leuchtmittel in der Lichtaustrittsebene bezüglich des Brennpunkts translatorisch verschiebbar oder translatorisch verschoben angeordnet ist, hat die Erfindung die Möglichkeit geschaffen, die austretenden parallelen Lichtstrahlen so abzulenken, dass sie nicht axial parallel zur Symmetrieachse des Parabolreflektors sondern unter einem Neigungswinkel zur Symmetrieachse des Parabolreflektors aus diesem austreten können. The fact that the electrical light source or the electrical lamp displaceable translationally with respect to the focal point in the light exit plane or is arranged in translation, the invention has the Created the possibility of deflecting the emerging parallel light beams in such a way that they are not axially parallel to the axis of symmetry of the parabolic reflector but at an angle to the axis of symmetry of the parabolic reflector can exit from this.
Somit ist es entsprechend der Erfindung möglich geworden, beispielsweise bei einer Bodeneinbau-Reflektorleuchte nur durch Verschieben der Lichtquelle in der Lichtaustrittsebene unter Vermeidung einer unmittelbar vom Reflektor ausgehenden Blendwirkung selbst dann eine Wand anzustrahlen, wenn die Lichtaustrittsebene der Reflektorleuchte mit der anzuleuchtenden Wand einen Winkel von 90° bildet.Thus it has become possible according to the invention, for example in the case of a recessed floor reflector luminaire, only by moving the light source in the light exit plane while avoiding a direct from Glare from the reflector, even then, to illuminate a wall, if the light exit plane of the reflector lamp matches the one to be illuminated Wall forms an angle of 90 °.
Dasselbe erfindungsgemäße Prinzip kann auch z.B. bei einer Wandeinbau-Reflektorleuchte oder bei einer erhöht positionierten erfindungsgemäßen Reflektorleuchte verwendet werden, um ebene Flächen, z.B. Straßen, Plätze, Eingänge etc. weitestgehend blendfrei auszuleuchten. So ist es z.B. möglich, in Einfahrten erfindungsgemäße Reflektorleuchten, insbesondere Wandeinbauleuchten, deren Lichtaustrittsebene sich vertikal erstreckt, etwa in Scheinwerferhöhe von Kraftwagen anzubringen, um den Fahrweg so auszuleuchten, dass der Fahrer selbst dann nicht geblendet wird, wenn sich die Leuchte direkt im Blickwinkel des Fahrers befindet.The same principle according to the invention can also be used e.g. with a wall recessed reflector lamp or in an elevated position according to the invention Reflector lamp can be used to level surfaces, e.g. Streets, squares, Illuminate entrances etc. largely without glare. So it is e.g. possible in Driveways according to the invention, in particular recessed wall lights, whose light exit plane extends vertically, for example at headlight height of motor vehicles to illuminate the route so that the driver is not dazzled even when the lamp is directly in the Viewing angle of the driver.
In jedem Falle wird eine von der Lichtquelle selbst ausgehende direkte Blendung entsprechend der Erfindung dadurch vermieden, dass das von der Lichtquelle ausgehende Licht nur zwischen der Lichtaustrittsebene und dem Scheitel zum Reflektor hin abstrahlt.In any case, a direct from the light source itself Glare avoided according to the invention in that the Light outgoing light only between the light exit plane and the Radiate the crown towards the reflector.
Entsprechend der Erfindung kann die Lichtquelle in der Lichtaustrittsebene translatorisch verschiebbar, also nachjustierbar oder für bestimmte vorgegebene Anwendungsfälle bereits fest justiert, d.h. translatorisch verschoben, ausgebildet sein.According to the invention, the light source can be in the light exit plane translationally displaceable, that is readjustable or for certain predetermined ones Use cases already adjusted, i.e. translated, be trained.
In weiterer Ausgestaltung der Erfindung ist die Lichtquelle in jeder verschobenen Position lösbar zu arretieren. Eine solche Anordnung gestattet z.B. bei mehreren in einer Reihe angeordneten Bodeneinbau-Reflektorleuchten trotz bauseitiger Toleranzen im Boden eine gleichmäßige Wandausleuchtung, weil der Lichtaustritt bei jeder Reflektorleuchte nachjustiert werden kann. In a further embodiment of the invention, the light source is shifted in each Lock the position releasably. Such an arrangement allows e.g. with several floor-mounted reflector lights arranged in a row despite on-site tolerances in the floor provide even wall illumination because the light emission can be readjusted with every reflector lamp.
Ein anderes Ausführungsbeispiel entsprechend der Erfindung ist dadurch gekennzeichnet, dass die Lichtquelle entlang einer Geraden verschiebbar ist. Angewandt auf das Beispiel einer Bodeneinbau-Reflektorleuchte, würde sich die Gerade, entlang welcher die Lichtquelle verschoben werden soll, horizontal und im übrigen senkrecht bezüglich der zu beleuchtenden Wandfläche erstrecken. Eine Verschiebung der Lichtquelle von der zu beleuchtenden Wandfläche weg bedeutet dabei eine größere Neigung des austretenden Lichts zur Wandfläche hin. Andererseits bewirkt eine Verschiebung in Richtung zu der zu beleuchtenden Wandfläche hin eine entgegengesetzte Neigung des austretenden Lichts von der Wandfläche weg.Another embodiment according to the invention is thereby characterized in that the light source is displaceable along a straight line. Applied to the example of a recessed floor reflector, would the straight line along which the light source is to be moved is horizontal and otherwise extend perpendicular to the wall surface to be illuminated. A shift of the light source from the wall surface to be illuminated away means a greater inclination of the emerging light to the wall surface out. On the other hand, a shift towards that causes illuminating wall surface towards an opposite inclination of the emerging Light away from the wall surface.
Eine einfache Bauform, mit der erreicht wird, dass das von der Lichtquelle ausgehende Licht nur zwischen der Lichtaustrittsebene und dem Reflektorscheitel zum Reflektor hin abstrahlt, wird entsprechend einem anderen Merkmal der Erfindung dadurch erzielt, dass die Lichtquelle an ihrer dem Scheitel des Reflektors abgewandten Seite von einer lichtundurchlässigen Abschirmung übergriffen ist. Dabei kann die Abschirmung gekrümmt, wie z.B. halbkugelförmig oder halbkreiszylinderförmig gekrümmt sein.A simple design that achieves that from the light source outgoing light only between the light exit plane and the Reflecting the top of the reflector towards the reflector is corresponding to another Feature of the invention achieved in that the light source at its the Vertex of the reflector facing away from an opaque Shielding is overlapped. The shield can be curved, e.g. be hemispherical or semicircular cylindrical.
Zur Vermeidung von unerwünschten Lichtreflexionen hat es sich als zweckmäßig herausgestellt, die freien Ränder der Abschirmung im wesentlichen in der Lichtaustrittsebene anzuordnen.To avoid unwanted light reflections, it has proven to be expediently exposed, the free edges of the shield essentially to be arranged in the light exit plane.
Zur Vermeidung einer die Lichtquelle gegebenenfalls thermisch zu sehr belastenden Mehrfachreflexion sieht die Erfindung außerdem vor, dass die der Lichtquelle zugewandte Innenfläche der Abschirmung matt oder schwarz, insbesondere mattschwarz ist.To avoid thermally the light source too much incriminating multiple reflection, the invention also provides that the Light source facing inner surface of the shield matt or black, in particular is matte black.
In Verbindung mit der erfindungsgemäßen lichtundurchlässigen Abschirmung ist entsprechend einem anderen Erfindungsmerkmal auch die Verwendung einer Lichtquelle möglich geworden, die im wesentlichen nach allen Richtungen abstrahlt.In connection with the opaque shield according to the invention is the use according to another feature of the invention a light source has become possible, essentially in all directions radiates.
Dabei kommen als für die erfindungsgemäßen Zwecke geeignete Lichtquellen
Niedervolt-Halogenlampen, beispielsweise des Typs QT 12 oder Halogen-Metalldampflampen
ceramic, beispielsweise des Typs HIT-CRI 35, in
Betracht.Here come as suitable light sources for the purposes of the invention
Low-voltage halogen lamps, for example of the
Bei solchen Lichtquellen, die jeweils einen etwa kreiszylindrischen Lampenkolben, und zwar einen Glaskolben, aufweisen, sieht die Erfindung vor, dass die Zylinderachse des Lampenkolbens im wesentlichen in der Lichtaustrittsebene angeordnet ist und dass die die Lichtquelle übergreifende lichtundurchlässige Abschirmung mindestens mittelbar seitlich am Reflektor gehalten ist.In the case of such light sources, each of which has an approximately circular-cylindrical lamp bulb, namely a glass bulb, the invention provides that the cylinder axis of the lamp bulb essentially in the light exit plane is arranged and that the light source overlapping opaque Shielding held at least indirectly on the side of the reflector is.
Dabei kann die lichtundurchlässige Abschirmung mindestens mittelbar entweder einendig oder beidendig am Reflektor gehalten sein. Um gegebenenfalls Lichtverluste zu vermeiden, hat es sich als zweckmäßig erwiesen, dass die lichtundurchlässige Abschirmung mindestens mittelbar einendig seitlich am Reflektor gehalten ist.The opaque shielding can at least indirectly be held on the reflector either at one end or at both ends. To where appropriate To avoid loss of light, it has proven to be useful that the opaque shield at least indirectly at one end on the side Reflector is held.
Weiterhin sieht die Erfindung in diesem Zusammenhang vor, dass die Lichtquelle gegebenenfalls einschließlich ihrer Fassungsarmatur bezüglich der lichtundurchlässigen Abschirmung relativverschiebbar angeordnet ist.Furthermore, the invention provides in this context that the Light source, if applicable, including its fitting with respect to the opaque shield is arranged relatively displaceable.
Um dabei zu gewährleisten, dass bei einer Verschiebung der Lichtquelle die lichtundurchlässige Abschirmung eine direkte Blendung mit Sicherheit vermeidet, sieht die Erfindung vor, dass die lichtundurchlässige Abschirmung eine Flächengröße aufweist, die unter Berücksichtigung des Verschiebeweges der Lichtquelle größer ist als die leuchtende Fläche der Lichtquelle. To ensure that when the light source moves the opaque shielding reliably avoids direct glare, The invention provides that the opaque shield a Has area size, taking into account the displacement of the Light source is larger than the luminous area of the light source.
Alternativ sieht die Erfindung zudem vor, dass die Lichtquelle einschließlich ihrer Fassungsarmatur und einschließlich der lichtundurchlässigen Abschirmung bezüglich des Reflektors relativverschieblich ist.Alternatively, the invention also provides that the light source including their fitting and including the opaque Shield is relatively displaceable with respect to the reflector.
Weiterhin sieht die Erfindung Lichtquellen vor, welche keine gesonderte Abschirmung benötigen, weil ihnen selbst, bauartbedingt, eine einseitig abstrahlende Lichtwirkung eigen ist. Solche Lichtquellen sind beispielsweise Lumineszenzdioden (LEDs). Demnach besteht ein anderes Erfindungsmerkmal darin, dass die Lichtquelle aus mindestens einer Lumineszenzdiode - LED - besteht.Furthermore, the invention provides light sources which are not separate Because of their design, shielding requires one-sided shielding radiating light effect is peculiar. Such light sources are, for example Luminescent diodes (LEDs). Accordingly, there is another feature of the invention in that the light source consists of at least one luminescent diode - LED - consists.
Einseitig abstrahlende Lumineszenzdioden, die zum Reflektorinnenraum hin abstrahlen, benötigen demnach keine gesonderte lichtundurchlässige Abschirmung.Single-sided light emitting diodes that lead to the interior of the reflector emit radiation, therefore do not need a separate opaque Shielding.
Für den Fall, dass die Erfindung sphärisch (z.B. halbkugelförmig) abstrahlende Lumineszenzdioden einsetzt, ist die Reflektorleuchte indessen mit einer gesonderten lichtundurchlässigen Abschirmung versehen.In the event that the invention is spherical (e.g. hemispherical) uses emitting luminescent diodes, the reflector lamp is included provided with a separate opaque shield.
Um eine hinreichende Lichtleistung zu erzielen, sieht die Erfindung in an sich bekannter Weise vor, dass mehrere Lumineszenzdioden, eng aneinandergefügt, eine gemeinsame Lichtquelle bilden.In order to achieve a sufficient light output, the invention looks at known way that several luminescent diodes, closely connected, form a common light source.
In einem solchen eng aneinandergefügten Feld von mehreren Lumineszenzdioden können zugleich bestimmte Konfigurationen, also Kurven (z.B. Kreise) oder Geraden enthalten sein.In such a closely spaced array of multiple diodes certain configurations, i.e. curves (e.g. Circles) or straight lines.
Eine translatorische Verschiebung der Lichtquelle kann demnach entsprechend weiteren Merkmalen der Erfindung mittelbar dadurch erzielt werden, dass von den mehreren, z.B. entlang einer Kurve oder entlang einer Geraden angeordneten Lumineszenzdioden nur einzelne oder mehrere einschaltbar sind. A translatory shift of the light source can accordingly further features of the invention can be achieved indirectly by that of the several, e.g. along a curve or along a straight line arranged luminescent diodes only one or more can be switched on.
Weitere Erfindungsmerkmale ergeben sich aus zusätzlichen Unteransprüchen.Further features of the invention result from additional subclaims.

In den Zeichnungen sind die dargestellten Reflektorleuchten unabhängig
von ihrer speziellen Bauweise stets einheitlich mit derselben Bezugsziffer 10
bezeichnet. Auch werden für alle miteinander vergleichbaren analogen Einzelbauteile
stets dieselben Bezugsziffern verwendet.In the drawings, the reflector lights shown are independent
due to their special design, always with the
Gemäß Fig. 1 ist eine Bodeneinbau-Reflektorleuchte 10 in einen Fußboden
B eingelassen, zu welchem sich eine Wand W vertikal erstreckt. 1 is a floor-mounted
Die Reflektorleuchte 10 weist als wesentliches Bauteil einen Parabolreflektor
11 auf, dessen Reflektorinnenfläche 12 verspiegelt ist. Zweckmäßig ist
die Reflektorinnenfläche 12 hochglänzend. Sie kann zudem strukturiert, wie z.B.
facettiert sein.The
An den Flansch 13 des Parabolreflektors 11 schließt sich eine kreiszylindrische
Aufnahme 14 an, in welcher eine trittfeste, lichtdurchlässige, klardurchsichtige
Glasplatte 15 gehalten ist.At the
Zwischen dem Reflektor 13 und der Glasplatte 15 können zudem weitere
Glasplattenelemente, wie z.B. eine Prismenplatte, eine Skulpturenlinse oder
eine Farbfilter-Platte angeordnet sein.In addition, more can be between the
Der Brennpunkt des Parabolreflektors 11 sind mit F und dessen Symmetrieachse
mit x bezeichnet. Die im Brennpunkt F angeordnete, als durchgezogener
Kreis dargestellte Lichtquelle, beispielsweise eine Niedervolt-Halogenlampe
des Typs QT 12, ist mit L bezeichnet.The focal point of the
Die außerdem als gestrichelter Kreis eingetragene Lichtquelle L ist um einen Verschiebeweg z von der Wand W und vom Brennpunkt F weg nach links verschoben.The light source L also entered as a dashed circle is around a displacement path z from the wall W and from the focal point F to the left postponed.
Die Lichtquelle L ist von einer länglichen lichtundurchlässigen Abschirmung
16 übergriffen, welche beispielsweise einen etwa halbkreisförmigen
Querschnitt aufweisen kann und welche den Parabolreflektor 11 und die Aufnahme
14 einseitig in einer seitlichen Aussparung 17 durchsetzt. Das rechts in
Fig. 1 gezeigte freie Ende der Abschirmung 17 ist mittels einer stirnseitigen
Kopfplatte 36 verschlossen.The light source L is of an elongated
Um die Lichtquelle L in Fig. 1 sichtbar zu machen, ist die Abschirmung
16 in ihrem freien Endbereich ausgebrochen dargestellt. Die Innenfläche 37 der
Abschirmung 16 ist mattschwarz. To make the light source L visible in Fig. 1, the shield is
16 shown broken out in its free end region. The
Die lichtundurchlässige Abschirmung 16 bewirkt, dass das von der Lichtquelle
L ausgehende Licht nur zwischen einer strichpunktiert dargestellten
Lichtaustrittsebene E und dem Scheitel S des Reflektors 11 hin abgestrahlt
wird. Die nach unten weisenden freien Ränder R der als Halbkreiszylinder ausgebildeten
Abschirmung 16 bestimmen dabei zugleich die Lage der Lichtaustrittsebene
E. Die lichttechnisch wirksame Reflektorinnenfläche 12 endet demnach
an der Lichtaustrittsebene E. Die an der der Lichtquelle L abgewandten
Seite der Lichtaustrittsebene E vorhandene restliche Reflektorinnenfläche 18 ist
demnach lichttechnisch unwirksam.The
Anhand von Fig. 1 ist auch vorstellbar, dass sämtliche von der im Brennpunkt
F angeordneten Lichtquelle L ausgehenden strichliniert dargestellten
Lichtstrahlen P einander parallel aus dem Parabolreflektor 11 austreten und im
übrigen die Lichtaustrittsebene E senkrecht schneiden.1, it is also conceivable that all of the focus

Light rays P emerge in parallel from the
Sobald die Lichtquelle L ihre gestrichelt eingezeichnete um den Verschiebeweg Z vom Brennpunkt F weg verschobene Lage eingenommen hat, werden die als Punktlinien dargestellten Lichtstrahlen V so abgelenkt, dass sie die Lichtaustrittsebene E unter einem Neigungswinkel schneiden und im übrigen zur Wand W hin gerichtet sind.As soon as the light source L is shown in dashed lines around the displacement path Z has assumed a position shifted away from the focal point F, the light rays V shown as dotted lines are deflected so that they intersect the light exit plane E at an angle of inclination and otherwise are directed towards the wall W.
Dies bedeutet weitestgehende Blendfreiheit für die sich auf dem Boden B
aufhaltenden Personen. Die Blendfreiheit kann noch dadurch verbessert werden,
dass im Bereich der linken Reflektorhälfte oberhalb der Abschirmung 16
und unterhalb der trittfesten Glasplatte 15 eine nicht dargestellte etwa segmentförmige
flächige lichtundurchlässige Abschirmplatte, vergleichbar der
Abschirmplatte 34 gemäß Fig. 3, eingebaut ist.This means as far as possible no glare for those on the floor B
detained people. The lack of glare can still be improved by
that in the area of the left reflector half above the
Anhand von Fig. 1 ist auch vorstellbar, dass anstelle der beiden Lichtquellen-Positionen (jeweils bei L; durchgezogene Darstellung; gestrichelte Darstellung) zwei oder mehr Lumineszenzdioden (LEDs) entlang einer Geraden oder gar als ganzes Feld eng aneinander angeordneter LEDs in der Lichtaustrittsebene angeordnet sein können. Durch alternatives Einschalten der LEDs lassen sich mittelbar ein Verschiebeweg Z, ein Mehrfaches dessen oder auch unterschiedlich gerichtete oder verlaufende Verschiebewege innerhalb der Lichtaustrittsebene E erzielen. Durch diese Maßnahmen kann demnach ohne eine mechanische Verstellung eine Lichtlenkung vorgenommen werden.1 it is also conceivable that instead of the two light source positions (each with L; solid representation; dashed representation) two or more luminescent diodes (LEDs) along a straight line or even as a whole field of closely arranged LEDs in the light exit plane can be arranged. By alternately switching on the LEDs can be a displacement path Z, a multiple thereof or indirectly differently directed or running displacement paths within the Achieve light emission level E. These measures can therefore be taken without a mechanical adjustment can be made to direct the light.
Dieselben Vorteile einer Blendfreiheit treten auch bei einer erfindungsgemäßen Wandeinbau-Reflektorleuchte auf. Hierzu stelle man sich im Zusammenhang mit Fig. 1 lediglich vor, dass anstelle des Bezugsbuchstabens B für den Boden der Bezugsbuchstabe W für die Wand und anstelle des Bezugsbuchstabens W für die Wand der Bezugsbuchstabe B für den Boden träte.The same advantages of freedom from glare also occur with an inventive one Recessed wall light on. To do this, put yourself in context with Fig. 1 just before that instead of the reference letter B for the bottom of the reference letter W for the wall and instead of the reference letter W for the wall of the reference letter B for the floor.
Die schematische Darstellung gemäß Fig. 2 ist bezogen auf die Darstellung
der Fig. 1. Indessen ist in Fig. 2 die sowohl in durchgezogenen als auch in
gestrichelten Linien darstellte Lichtquelle L etwa ihrer tatsächlichen Form entsprechend
dargestellt. Die Lampe L weist einen Glaslampenkolben 19, einen
Brenner 20 und Sockelstifte 21 auf. Die Zylinderachse y des Glaslampenkolbens
19 liegt in der Lichtaustrittsebene E.2 is based on the illustration
of Fig. 1. Meanwhile, in Fig. 2 is both in solid and in
Dashed lines represented light source L approximately according to their actual shape
shown. The lamp L has a
Die konstruktiven Darstellungen entsprechend den Fig. 3-6 sind an sich ohne umfangreiche zusätzliche Erklärungen verständlich. Folgendes sei noch ergänzt:The constructive representations corresponding to FIGS. 3-6 are in themselves understandable without extensive additional explanations. The following is still added:
Entsprechend den an einen Wand- oder Bodeneinbau zu stellenden
mechanischen Anforderungen weisen die Reflektorleuchten 10 jeweils ein stabiles
Leuchtengehäuse 21 aus Metalldruckguss oder aus einem geeigneten
Kunststoff auf. Das Gehäuse 21 enthält eine Kabeldurchführung 22, eine elektrische
Anschlusseinrichtung 23 sowie eine Montageplatte 24 zur Halterung
eines etwa topfartigen Innengehäuses 25, mit welchem der Parabolreflektor 11
an seinem Scheitel S verschraubt ist. Corresponding to those to be installed on a wall or floor
mechanical requirements, the reflector lights 10 each have a
Die in Fig. 3 dargestellte Lichtquelle L befindet sich im Brennpunkt F. Demzufolge durchsetzen die Lichtstrahlen P die Lichtdurchtrittsebene E orthogonal. Es ist indessen vorstellbar, dass die austretenden Lichtstrahlen (vgl. Lichtstrahlen V in Fig. 1) nach unten zum Boden B hin geneigt austreten, wenn die Lichtquelle L nach oben verschoben wird.The light source L shown in FIG. 3 is located at the focal point F. As a result, the light rays P penetrate the light passage plane E orthogonally. However, it is conceivable that the emerging light rays (cf. Light rays V in Fig. 1) emerge inclined downwards towards the bottom B if the light source L is shifted upwards.
Hierzu ist ein etwa konsolartiger Lampenträger 26 vorgesehen, an welchem
auch die lichtundurchlässige Abschirmung 16 bewegungseinheitlich
gehalten ist. Der Lampenträger 26 nimmt überdies die Fassungsarmatur 27 für
die Lichtquelle L auf.For this purpose, an approximately console-
Wenn man die in einer Gewindebuchse 29 auf der Montageplatte 24
gehaltene Klemmschraube 28 löst, kann man den Lampenträger 26 entlang
seiner Verstellschlitze 30 und 31 um den Betrag Z nach oben verschieben,
worauf eine Ablenkung der Lichtstrahlen zum Boden B hin erfolgt.If one in a threaded
Außerhalb des Reflektors 11 zeigt die Wandeinbau-Reflektorleuchte 10
gemäß den Fig. 3 und 4 eine Skulpturenlinse 32, welche für eine Streuung des
aus dem Parabolreflektor 11 austretenden Lichts sorgt. Die Skulpturenlinse 32
ist mittels einer Dichtung 33 eingefasst, welche im oberen Bereich des Reflektors
11 nach unten heruntergezogen ist, um eine Anlagefläche für eine etwa
segmentartige lichtundurchlässige Lichtabschirmplatte 34 zu bieten.Outside the
Fig. 4 zeigt die Leuchte 10 gemäß Fig. 3 in einer gegenüber Fig. 3 um
90° verschwenkten Montagelage. Fig. 3 erhält man, wenn der Betrachter in der
Darstellung gemäß Fig. 3 der mit IV bezeichneten Blickrichtung folgt.FIG. 4 shows the
Die Bodeneinbau-Reflektorleuchte 10 gemäß den Fig. 5 und 6 unterscheidet
sich außer durch ihre Zweckbestimmung und ihre andere Einbaulage
von der Leuchte gemäß den Fig. 3 und 4 nur dadurch, dass zusätzlich eine
Farbfilter-Glasplatte 35 und oberhalb der Skulpturenlinse 32 eine trittfeste Glasplatte
15 vorgesehen ist. The floor recessed
Gemäß Fig. 5 befindet sich die Lichtquelle L in ihrer Brennpunktlage, so dass die Lichtstrahlen P die Lichtdurchtrittsebene E orthogonal schneiden.5, the light source L is in its focal position, so that the light rays P intersect the light passage plane E orthogonally.
Anhand von Fig. 5 ist wiederum vorstellbar, dass die Lichtstrahlen (vgl.
Lichtstrahlen V gemäß Fig. 1) zur Wand W hin abgelenkt werden, wenn nach
Lösen der Klemmschraube 28 der Lampenträger 26 von dem Brennpunkt F und
der Wand W weg entsprechend dem Verschiebemaß Z nach links verschoben
werden.5, it is again conceivable that the light rays (cf.
Light rays V according to FIG. 1) are deflected towards the wall W if after
