- the reflector recesses 2 are each equipped with a central rear recess 6.
- each of the reflector recesses 2 has a front-side reflector opening 8.
- light emitted by a light source arranged thereunder can fall through, or a light source can protrude from the rear or below into the recess 6.

- light emitted perpendicularly from the light source (which runs parallel to the longitudinal axis L) or light whose angle to the longitudinal axis L is less than or equal to an opening angle of the reflector depression 2 can emerge without reflection from the reflector depression 2 through the associated reflector opening 8.
- spring elements 10 are integrated here.
- the spring elements 10 respectively project forward (in the direction of the longitudinal axis L) beyond the remaining reflector 1 and thus represent the uppermost or furthest forwardly arranged points P1 of the reflector 1.
- the spring elements 10 are each designed as two-sided clamped beams, which are formed centrally in the form of an inverted "U" 11. The bottom of the "U” 11 thus represents the foremost point P1 of the reflector 1, but this is not a compelling design.
- the reflector 1 further comprises four rotationally symmetrical to the longitudinal axis L arranged, rearwardly or rearwardly projecting spacer 12.
- the spacers 12 define the lowermost or rearmost point P2 of the reflector 1.

- the translucent cover 17 has a substantially disc-shaped or plate-shaped upper side 18 and a laterally encircling edge 19, that is to say it is configured here in a substantially cup-shaped manner in the opposite direction.
- the spring elements 10 are pressed down and press the reflector 1 on the support 14, wherein a distance between the respective rear recess 6 and the LED support 14 through the Spacer 12 is determined.
- the spacers 12 also delimit the LED carrier 14 laterally, so that they serve as general positioning elements, which also prevent a lateral offset of the reflector 1 with respect to the LED carrier 14 here.

- Each of the spring elements 34 is formed as an obliquely forwardly or upwardly (in the longitudinal direction L) directed, cantilever beam.
- the free end 35 of the spring elements 34 represents the highest or the most forward projecting point P1. Presses the cover 17 on the front side 7 of the reflector 31, it pivots the spring elements 34 elastically downwards, whereby the reflector 31 on the Support plate can be pressed, and to compensate for manufacturing and assembly tolerances.
- the maximum tolerance dimension may substantially correspond to the extent of the projection of the free end 35, which represents the furthest projecting point P1, over the front side 7 of the reflector 31.
- the reflector 31 is integrally formed as a plastic part.
- FIG. 7 shows in oblique view from above a reflector holder 40 of a reflector 41 according to a third embodiment.
- the reflector holder 40 made of plastic has three insertion openings 42 each for use of a reflector insert 46 (see further figures) made of aluminum, the reflector inserts 46 can be placed on corresponding edges or annular grooves 43 and positioned in these.
- the reflector holder 40 here has three rearwardly directed (directed against the longitudinal direction L) support elements 44, whose rear ends are formed as insertion pins 51.

- the spring element 45 which can be supported by means of the support elements 44, for example, on a housing of a lighting device and / or an LED support, elastically deformed and exerts a forward (in the longitudinal direction L) directed counterforce, which now pushes the reflector holder 40 forward.
- Figure 8 shows in oblique view from above or front and Figure 9 shows in a view obliquely from below the reflector 41 according to the third embodiment, now in each of the insertion openings 42 from the front, a respective reflector insert 46 is inserted.
- the reflector insert 46 sits on the associated annular groove 43. Without further action, the reflector inserts 46 loosely rest on the insertion openings 42.
- the reflector inserts 46 can be pressed, for example, into the insertion openings 42, eg by a light-permeable cover (o.Fig.).
- Each of the reflector inserts 46 has a rear-side recess 6 and a front-side reflector opening 8, wherein the inner side 3 of the respective reflector insert 46 is designed to be reflective.
- the reflection behavior of the now four-part reflector 41 is similar to the reflection behavior of the reflector 31 and therefore will not be further described here.

Reflektoren werden zur Montage in LED-Lampen bisher typischerweise geklebt oder geklemmt. Allgemein tritt dabei das Problem auf, dass mechanische Toleranzen ausgeglichen werden müssen. Dies wird bisher dadurch gelöst, dass ein oder mehrere Ausgleichselemente, wie Andrückfedern, verwendet werden.Reflectors are typically glued or clamped for mounting in LED lamps. In general, the problem arises that mechanical tolerances must be compensated. This has hitherto been solved by using one or more compensating elements, such as pressure springs.
Es ist die Aufgabe der vorliegenden Erfindung, einen Reflektor für eine Beleuchtungseinheit bereitzustellen, welcher besonders preisgünstig herstellbar ist und einen kompakten und effektiven Toleranzausgleich ermöglicht.It is the object of the present invention to provide a reflector for a lighting unit, which is particularly inexpensive to produce and allows a compact and effective tolerance compensation.
Diese Aufgabe wird gemäß den Merkmalen der unabhängigen Ansprüche gelöst. Bevorzugte Ausführungsformen sind insbesondere den abhängigen Ansprüchen entnehmbar.This object is achieved according to the features of the independent claims. Preferred embodiments are in particular the dependent claims.
Die Aufgabe wird gelöst durch einen Reflektor für eine Beleuchtungseinheit, wobei der Reflektor mindestens eine rückseitige Ausnehmung für jeweils eine Lichtquelle und mindestens eine vorderseitige Reflektoröffnung aufweist.The object is achieved by a reflector for a lighting unit, wherein the reflector has at least one rear-side recess for a respective light source and at least one front-side reflector opening.
Unter einem Reflektor kann insbesondere ein allgemein strahlformendes Element verstanden werden, welches insbesondere als ein spiegelndes Element oder als ein diffus reflektierendes Element ausgestaltet sein kann.A reflector may, in particular, be understood as meaning a generally beam-shaping element, which may in particular be designed as a reflecting element or as a diffusely reflecting element.
Durch den Reflektor kann allgemein zumindest ein Teil des Lichts, das von der jeweils einen Lichtquelle ausgestrahlt wird, abgelenkt werden.In general, at least part of the light emitted by the respective one light source can be deflected by the reflector.
Dabei kann die Lichtquelle unterhalb bzw. in rückwärtiger Richtung beabstandet von der zugehörigen Ausnehmung angeordnet sein. Zumindest ein Teil des von der Lichtquelle ausgestrahlten Lichts fällt dann durch die Ausnehmung, kann folgend zumindest teilweise durch den Reflektor (ggf. mehrfach) reflektiert werden und tritt im Weiteren durch die Reflektoröffnung aus. Insbesondere kann z.B. ein von der Lichtquelle direkt nach oben bzw. senkrecht oder unter einem geringen Winkel dazu durch die Ausnehmung fallendes Licht ohne Reflexion durch die Reflektoröffnung austreten.In this case, the light source can be arranged below or in the rearward direction spaced from the associated recess. At least part of the light emitted by the light source then falls through the recess, can follow at least partially reflected by the reflector (possibly several times) and subsequently emerges through the reflector opening. In particular, for example, a light falling directly from the light source upwards or vertically or at a slight angle thereto through the recess can exit through the reflector opening without reflection.
Die mindestens eine rückseitige Ausnehmung kann in einen rückseitigen Reflektorboden eingebracht sein.The at least one rear-side recess can be introduced into a rear-side reflector base.
Alternativ kann die Lichtquelle zumindest teilweise in die Ausnehmung eingeführt sein. Das von ihr abgestrahlte Licht kann dann ganz oder teilweise durch den Reflektor reflektiert werden und folgend durch die Reflektoröffnung austreten.Alternatively, the light source may be at least partially inserted into the recess. The light emitted by it can then be wholly or partially reflected by the reflector and subsequently emerge through the reflector opening.
In den Reflektor ist ferner mindestens ein Federelement integriert. Durch das integrierte Federelement kann der Reflektor für einen Toleranzausgleich mit hoher Genauigkeit angedrückt werden. Eine Fehlpositionierung eines separaten Federelements, z.B. durch ein Verkanten, entfällt. Der Reflektor mit integriertem Federelement ist zudem preiswerter umsetzbar als ein herkömmlicher Reflektor mit dem separaten Federelement. Es kann mindestens ein Bauelement eingespart werden. Auch wird eine besonders kompakte Bauform ermöglicht.In the reflector at least one spring element is further integrated. Due to the integrated spring element, the reflector can be pressed for tolerance compensation with high accuracy. Misalignment of a separate spring element, e.g. by tilting, deleted. The reflector with integrated spring element is also cheaper to implement than a conventional reflector with the separate spring element. It can be saved at least one component. Also, a particularly compact design is possible.
Das Federelement wirkt dabei vorzugsweise im Wesentlichen parallel zur Längsachse des Reflektors und/oder parallel zu einer Hauptabstrahlrichtung der Leuchtvorrichtung und/oder mindestens einer Lichtquelle der Leuchtvorrichtung.The spring element preferably acts substantially parallel to the longitudinal axis of the reflector and / or parallel to a main emission direction of the lighting device and / or at least one light source of the lighting device.
Der Reflektor kann einen Grundkörper aus Metall oder Kunststoff aufweisen. Der Reflektor kann z.B. ein spritzgegossener Kunststoffgrundkörper sein, dessen Reflektorwand bzw. Reflektorwände insbesondere nachträglich mit einer reflektierenden Fläche versehen worden sind, z.B. mit einer reflektierenden Folie oder einer reflektierenden Beschichtung.The reflector may have a base made of metal or plastic. The reflector may e.g. be an injection-molded plastic base body whose reflector wall or reflector walls have been provided in particular subsequently with a reflective surface, e.g. with a reflective foil or a reflective coating.
Das mindestens eine Federelement kann insbesondere einen einstückigen Teil des Reflektors darstellen.The at least one spring element can in particular represent an integral part of the reflector.
Es ist eine Ausgestaltung, dass das mindestens eine Federelement nach vorne hinausragt. Unter "nach vorne" kann insbesondere ein Bereich oberhalb bzw. vor der mindestens einen vorderseitigen Reflektoröffnung verstanden werden. Unter "nach vorne" kann insbesondere auch ein Bereich verstanden werden, welcher bezüglich einer Längsachse des Reflektors oberhalb der mindestens einen vorderseitigen Reflektoröffnung liegt. Auch das von dem mindestens einen Reflektor abgestrahlte Licht wird "nach vorne" in einen entsprechenden vorderen Halbraum abgestrahlt. Die Längsachse des Reflektors kann insbesondere im Wesentlichen auch einer Symmetrieachse und/oder einer optischen Achse entsprechen. Durch das mindestens eine nach vorne ragende Federelement kann der Reflektor von vorne in die rückwärtige Richtung gedrückt werden, wobei eine Fertigungstoleranz über eine Änderung eines Federwegs des mindestens einen Federelements ausgleichbar ist. Insbesondere bei mehr als einem Federelement, insbesondere bei drei oder mehr Federelementen, ist so auch eine Verkantung des Reflektors einfach toleranzausgleichbar.It is an embodiment that the at least one spring element protrudes forward. In particular, an area above or in front of the at least one front side can be referred to as "forward" Reflector opening to be understood. By "forward" may in particular also be understood a region which lies with respect to a longitudinal axis of the reflector above the at least one front-side reflector opening. The light emitted by the at least one reflector is also radiated "forwards" into a corresponding front half-space. In particular, the longitudinal axis of the reflector can essentially also correspond to an axis of symmetry and / or an optical axis. By the at least one forwardly projecting spring element of the reflector can be pressed from the front in the rearward direction, wherein a manufacturing tolerance on a change of a spring travel of the at least one spring element is compensated. In particular, in more than one spring element, in particular in three or more spring elements, as well as a tilting of the reflector is easily tolerance compensated.
Es ist noch eine Ausgestaltung, dass das mindestens eine Federelement als ein schräg nach vorne gerichteter, einseitig eingespannter Balken ausgebildet ist. Der Balken ist insbesondere an seiner Einspannung elastisch verschwenkbar. Dieser ist besonders einfach und kompakt umsetzbar. Das Federelement kann auch als ein einseitiger Hebel angesehen werden. Sein freies Ende kann dann als Aufsatzpunkt für ein vorderseitig auf den Reflektor drückendes Element, z.B. eine Abdeckplatte, dienen.It is still an embodiment that the at least one spring element is designed as an obliquely forwardly directed, one-sided clamped beam. The beam is elastically pivotable in particular at its restraint. This is particularly simple and compact to implement. The spring element can also be regarded as a one-sided lever. Its free end may then serve as a point of attachment for a member pressing on the front of the reflector, e.g. a cover plate, serve.
Es ist eine alternative Ausgestaltung, dass das mindestens eine Federelement als ein zweiseitig eingespannter Balken ausgebildet ist. Das nach vorne Hinausragen kann beispielsweise dadurch erreicht werden, dass ein Bereich zwischen den beiden eingespannten Enden hochgebogen ist, z.B. in Form eines umgekehrten "U".It is an alternative embodiment that the at least one spring element is designed as a two-sided clamped beam. For example, the forward protrusion can be achieved by bending an area between the two clamped ends, e.g. in the form of an inverted "U".
Es ist eine besondere Ausgestaltung, dass der Reflektor mindestens ein rückwärtig hervorstehendes Positionierelement, insbesondere Abstandshalter, aufweist. Durch das mindestens eine Federelement kann der Reflektor auch bei einem toleranzbehafteten Abstand zwischen der Vorderseite des Reflektors und dem vorderseitig auf den Reflektor drückenden Element sicher fixiert werden. Insbesondere kann durch das mindestens eine Positionierelement ein Abstand zu der mindestens einen Lichtquelle präzise eingehalten werden, was eine genau reproduzierbare Strahlführung ermöglicht.It is a particular embodiment that the reflector has at least one rearwardly projecting positioning element, in particular spacers. By the least a spring element, the reflector can be securely fixed even at a tolerance-prone distance between the front of the reflector and the front side of the reflector pressing element. In particular, a distance to the at least one light source can be precisely maintained by the at least one positioning element, which enables a precisely reproducible beam guidance.
Es ist eine alternative Ausgestaltung, dass das mindestens eine Federelement in ein jeweiliges Stützelement des Reflektors integriert ist. Ein Stützelement kann insbesondere in eine rückwärtige Richtung ausgerichtet sein und den Reflektor entsprechend rückwärtig abstützen. Durch das mindestens eine integrierte Federelement wird bei einem Zusammendrücken des Reflektors, z.B. bei einem Aufsetzen einer Abdeckplatte, der Reflektor nach vorne gedrückt, z.B. auf die Abdeckplatte. So kann der Reflektor beispielsweise ohne Abstandshalter bzw. "schwebend" in Bezug auf die mindestens eine Lichtquelle montiert werden.It is an alternative embodiment that the at least one spring element is integrated in a respective support element of the reflector. A support member may be aligned in particular in a rearward direction and support the reflector back accordingly. By the at least one integrated spring element is at a compression of the reflector, e.g. when placing a cover plate, the reflector pushed forward, e.g. on the cover plate. For example, the reflector can be mounted without a spacer or "floating" with respect to the at least one light source.
Es ist eine besondere Ausgestaltung, dass der Reflektor mindestens zweiteilig aus einem Reflektorhalter und mindestens einem Reflektoreinsatz aufgebaut ist, wobei der mindestens eine Reflektoreinsatz jeweils mindestens eine der Ausnehmungen und mindestens eine der vorderseitigen Reflektoröffnungen aufweist. Der mindestens eine Reflektoreinsatz weist insbesondere die reflektierenden Flächen auf. Der mindestens eine Reflektoreinsatz ist von vorne in den Reflektorhalter einsetzbar, wobei das mindestens eine Federelement in ein jeweiliges Stützelement des Reflektorhalters integriert ist. Bei dieser Ausgestaltung kann das mindestens eine Federelement den Reflektor insbesondere gegen eine Abdeckplatte drücken, wodurch wiederum der mindestens eine Reflektoreinsatz in den Reflektorhalter gedrückt und so dort gehalten wird.It is a particular embodiment that the reflector is constructed at least in two parts from a reflector holder and at least one reflector insert, wherein the at least one reflector insert has at least one of the recesses and at least one of the front reflector openings. The at least one reflector insert has in particular the reflective surfaces. The at least one reflector insert can be inserted from the front into the reflector holder, wherein the at least one spring element is integrated in a respective support element of the reflector holder. In this embodiment, the at least one spring element can press the reflector in particular against a cover plate, which in turn pushes the at least one reflector insert into the reflector holder and thus held there.
Allgemein kann der mindestens eine Reflektoreinsatz genau eine der Ausnehmungen und genau eine der vorderseitigen Reflektoröffnungen aufweisen. Insbesondere können mehrere Reflektoreinsätze jeweils genau eine der Ausnehmungen und genau eine der vorderseitigen Reflektoröffnungen aufweisen. Als eine Alternative kann der mindestens eine Reflektoreinsatz mehrere der Ausnehmungen und genau eine der vorderseitigen Reflektoröffnungen aufweisen, z.B. bei ineinanderlaufenden Reflektorflächen.In general, the at least one reflector insert can be exactly one of the recesses and exactly one of the front reflector openings exhibit. In particular, a plurality of reflector inserts may each have exactly one of the recesses and exactly one of the front reflector openings. As an alternative, the at least one reflector insert may have a plurality of the recesses and exactly one of the front reflector openings, for example in the case of reflector surfaces running into one another.
Allgemein kann der Reflektor einstückig oder mehrstückig ausgebildet sein. Die einstückige Ausgestaltung (einschließlich des mindestens einen Federelements) weist den Vorteil auf, dass die Herstellung und Montage kostengünstig durchgeführt werden können, z.B. mittels eines Spritzgussverfahrens. Das Spritzgussverfahren kann z.B. einstufig oder mehrstufig durchgeführt werden. Auch treten keine Fehlpassungen der einzelnen funktionalen Komponenten (Reflektorhalter, Reflektorvertiefung(en), Federelement(e) usw.) mehr auf. Zudem weist der einstückige Reflektor eine hohe Stabilität und Passgenauigkeit auf.In general, the reflector may be formed in one piece or in several pieces. The one-piece design (including the at least one spring element) has the advantage that the manufacture and assembly can be carried out inexpensively, e.g. by means of an injection molding process. The injection molding process can e.g. be carried out in one or more stages. Also, no mismatching of the individual functional components (reflector holder, reflector recess (s), spring element (s), etc.) occur more. In addition, the one-piece reflector has a high stability and accuracy of fit.
Die Aufgabe wird auch gelöst durch eine Leuchtvorrichtung, welche mindestens einen solchen Reflektor aufweist. Durch das integrierte Federelement kann der Reflektor für einen Toleranzausgleich mit hoher Genauigkeit angedrückt werden, z.B. mittels einer lichtdurchlässigen Abdeckplatte. Eine Fehlpositionierung, z.B. durch ein Verkanten eines separaten Federelements, entfällt. Der Reflektor mit integriertem Federelement ist zudem preiswerter umsetzbar als ein herkömmlicher Reflektor mit dem separaten Federelement. Es kann mindestens ein Bauelement eingespart werden. Auch wird eine besonders kompakte Bauform ermöglicht.The object is also achieved by a lighting device which has at least one such reflector. Due to the integrated spring element, the reflector can be pressed for tolerance compensation with high accuracy, e.g. by means of a translucent cover plate. Mispositioning, e.g. by tilting a separate spring element deleted. The reflector with integrated spring element is also cheaper to implement than a conventional reflector with the separate spring element. It can be saved at least one component. Also, a particularly compact design is possible.
Es ist eine Weiterbildung, dass die mindestens eine vorderseitige Reflektoröffnung mittels eines auf den Reflektor drückenden Abdeckelements abgedeckt wird.It is a further development that the at least one front-side reflector opening is covered by means of a covering element pressing on the reflector.
Es ist noch eine Weiterbildung, insbesondere falls der Reflektor mindestens einen rückwärtig hervorstehenden Abstandshalter aufweist, dass die mindestens eine Lichtquelle auf einem Lichtquellenträger angeordnet ist und der mindestens eine Abstandhalter auf dem Lichtquellenträger aufsitzt. So kann das mindestens eine Federelement den Reflektor sicher und in einer definierten Position bezüglich der mindestens einen Lichtquelle halten.It is still a further development, in particular if the reflector has at least one rearwardly projecting spacer, that the at least one light source is arranged on a light source carrier and the at least one spacer is seated on the light source carrier. Thus, the at least one spring element can hold the reflector securely and in a defined position relative to the at least one light source.
Es ist zudem eine Weiterbildung, insbesondere falls das mindestens eine Federelement in ein jeweiliges Stützelement des Reflektors integriert ist, dass die mindestens eine Lichtquelle auf einem Lichtquellenträger angeordnet ist und der Lichtquellenträger und das jeweilige Stützelement an einem Gehäuse der Leuchtvorrichtung angeordnet sind. Dadurch können die Lichtquellen und der Reflektor unabhängig und ohne direkten mechanischen Kontakt an dem Gehäuse montiert werden. Insbesondere ist so eine schwebende Positionierung des Reflektors über der mindestens einen Lichtquelle einfach möglich.It is also a development, in particular if the at least one spring element is integrated in a respective support element of the reflector, that the at least one light source is arranged on a light source carrier and the light source carrier and the respective support element are arranged on a housing of the lighting device. As a result, the light sources and the reflector can be mounted independently of the housing without direct mechanical contact. In particular, such a floating positioning of the reflector over the at least one light source is easily possible.
Bevorzugterweise umfasst die mindestens eine Lichtquelle mindestens eine Leuchtdiode. Bei Vorliegen mehrerer Leuchtdioden können diese in der gleichen Farbe oder in verschiedenen Farben leuchten. Eine Farbe kann monochrom (z.B. rot, grün, blau usw.) oder multichrom (z.B. weiß) sein. Auch kann das von der mindestens einen Leuchtdiode abgestrahlte Licht ein infrarotes Licht (IR-LED) oder ein ultraviolettes Licht (UV-LED) sein. Mehrere Leuchtdioden können ein Mischlicht erzeugen; z.B. ein weißes Mischlicht. Die mindestens eine Leuchtdiode kann mindestens einen wellenlängenumwandelnden Leuchtstoff enthalten (Konversions-LED). Die mindestens eine Leuchtdiode kann in Form mindestens einer einzeln gehäusten Leuchtdiode oder in Form mindestens eines LED-Chips vorliegen. Mehrere LED-Chips können auf einem gemeinsamen Substrat ("Submount") montiert sein. Die mindestens eine Leuchtdiode kann mit mindestens einer eigenen und/oder gemeinsamen Optik zur Strahlführung ausgerüstet sein, z.B. mindestens einer Fresnel-Linse, Kollimator, und so weiter. Anstelle oder zusätzlich zu anorganischen Leuchtdioden, z.B. auf Basis von InGaN oder A-lInGaP, sind allgemein auch organische LEDs (OLEDs, z.B. Polymer-OLEDs) einsetzbar. Auch können z. B. Diodenlaser verwendet werden. Alternativ kann die mindestens eine Lichtquelle z.B. mindestens einen Diodenlaser aufweisen.Preferably, the at least one light source comprises at least one light-emitting diode. If several LEDs are present, they can be lit in the same color or in different colors. A color can be monochrome (eg red, green, blue etc.) or multichrome (eg white). The light emitted by the at least one light-emitting diode can also be an infrared light (IR LED) or an ultraviolet light (UV LED). Several light emitting diodes can produce a mixed light; eg a white mixed light. The at least one light-emitting diode may contain at least one wavelength-converting phosphor (conversion LED). The at least one light-emitting diode can be in the form of at least one individually housed light-emitting diode or in the form of at least one LED chip. Several LED chips can be mounted on a common substrate ("submount"). The at least one light emitting diode may be equipped with at least one own and / or common optics for beam guidance, eg at least one Fresnel lens, Collimator, and so on. Instead of or in addition to inorganic light-emitting diodes, for example based on InGaN or A-lnGaP, it is generally also possible to use organic LEDs (OLEDs, eg polymer OLEDs). Also z. B. diode lasers are used. Alternatively, the at least one light source may have, for example, at least one diode laser.
LED-Lichtquellen zeichnen sich unter anderem durch eine hohe Effizienz, eine hohe Lebensdauer, eine schnelle Ansprechzeit und eine vergleichsweise geringe Empfindlichkeit gegen Stöße und Vibrationen aus. Außerdem eignen sich LED-Lichtquellen für einen Einbau in optische Systeme, insbesondere Reflektoren. LED-Lichtquellen können aus diesem Grund in Beleuchtungseinheiten eingesetzt werden, bei denen bisher oftmals Glüh- oder Entladungslampen verwendet wurden, insbesondere in Leuchten für die Allgemeinbeleuchtung aber auch in speziellen Beleuchtungsanwendungen, beispielsweise der Flugplatzbefeuerung. Konventionell werden hierfür bisher überwiegend Halogenreflektorlampen eingesetzt.Among other things, LED light sources are characterized by high efficiency, a long service life, a fast response time and a comparatively low sensitivity to shocks and vibrations. In addition, LED light sources are suitable for installation in optical systems, in particular reflectors. For this reason, LED light sources can be used in lighting units in which incandescent or discharge lamps have hitherto often been used, in particular in lamps for general lighting but also in special lighting applications, for example aerodrome lighting. Conventionally, halogen reflector lamps have hitherto been used for this purpose.
Jedoch ist die Erfindung nicht auf Halbleiterleuchtelemente (Leuchtdioden, Diodenlaser usw.) beschränkt, sondern kann auch Lichtquellen anderer Art, z.B. Miniaturglühlampen oder Entladungslampen, umfassen.However, the invention is not limited to semiconductor light-emitting elements (light-emitting diodes, diode lasers, etc.), but may also include light sources of other types, e.g. Miniature incandescent or discharge lamps include.

Durch die jeweilige rückseitige Ausnehmung 6 kann von einer darunter angeordneten Lichtquelle abgestrahltes Licht hindurchfallen, oder es kann eine Lichtquelle von hinten bzw. unten in die Ausnehmung 6 hineinragen. Das von der Lichtquelle abgestrahlte Licht kann folgend zumindest teilweise an den Reflektorvertiefungen 2 reflektiert werden und dann an der zugehörigen Reflektoröffnung 8 austreten. Teilweise kann auch senkrecht von der Lichtquelle abgestrahltes Licht (welches parallel zu der Längsachse L läuft) oder Licht, dessen Winkel zu der Längsachse L geringer oder gleich einem Öffnungswinkel der Reflektorvertiefung 2 ist, ohne Reflexion an der Reflektorvertiefung 2 durch die zugehörige Reflektoröffnung 8 austreten.Through the respective
In einen oberen Rand 9 des Reflektors 1 sind hier vier rotationssymmetrisch zu der Längsachse L angeordnete Federelemente 10 integriert. Die Federelemente 10 ragen jeweils nach vorne (in Richtung der Längsachse L) über den restlichen Reflektor 1 hinaus und stellen also die obersten bzw. am weitesten vorne angeordneten Punkte P1 des Reflektors 1 dar. Die Federelemente 10 sind jeweils als zweiseitig eingespannte Balken ausgebildet, welche mittig in Form eines umgekehrten "U" 11 geformt sind. Der Boden des "U" 11 stellt somit den vordersten Punkt P1 des Reflektors 1 dar, wobei dies jedoch keine zwingende Ausgestaltung ist.In an
Der Reflektor 1 weist ferner vier rotationssymmetrisch zu der Längsachse L angeordnete, rückwärtig oder rückseitig hervorstehende Abstandshalter 12 auf. Die Abstandshalter 12 definieren den untersten bzw. am weitesten rückwärtig angeordneten Punkt P2 des Reflektors 1.The
Dadurch, dass die Oberseite 18 der Abdeckung 17 auf den Reflektor 1 drückt, werden die Federelemente 10 nach unten gedrückt und pressen so den Reflektor 1 auf den Träger 14, wobei ein Abstand zwischen der jeweiligen rückwärtigen Ausnehmung 6 und dem LED-Träger 14 durch die Abstandshalter 12 bestimmt wird. Die Abstandshalter 12 begrenzen den LED-Träger 14 auch seitlich, so dass sie als allgemeine Positionierungselemente dienen, welche hier auch einen seitlichen Versatz des Reflektors 1 bezüglich des LED-Trägers 14 verhindern. Durch die Federelemente 10 kann auf einfache und kompakte Weise eine Aufsatztoleranz der Abdeckung 17 ausgeglichen werden, und zwar bis zu einer Höhe b des Überstands.The fact that the top 18 of the
Jedes der Federelemente 34 ist als ein schräg nach vorne bzw. oben (in Längsrichtung L) gerichteter, einseitig eingespannter Balken ausgebildet. Das freie Ende 35 der Federelemente 34 stellt den jeweils höchsten bzw. den am weitesten nach vorne vorstehenden Punkt P1 dar. Drückt die Abdeckung 17 auf die Vorderseite 7 des Reflektors 31, verschwenkt sie die Federelemente 34 elastisch nach unten, wodurch der Reflektor 31 auf die Trägerplatte gedrückt werden kann, und zwar unter Ausgleich von Herstellungs- und Montagetoleranzen. Das maximale Toleranzmaß kann insbesondere im Wesentlichen dem Maß des Überstands des freien Endes 35, welches den am weitesten nach vorne vorstehenden Punkt P1 darstellt, über die Vorderseite 7 des Reflektors 31 entsprechen.Each of the
Auch hier ist der Reflektor 31 einstückig als ein Kunststoffteil ausgebildet.Again, the
Jeder der Reflektoreinsätze 46 weist eine rückseitige Ausnehmung 6 und eine vorderseitige Reflektoröffnung 8 auf, wobei die Innenseite 3 des jeweiligen Reflektoreinsatzes 46 reflektierend ausgebildet ist. Das Reflexionsverhalten des nun vierteiligen Reflektors 41 ist ähnlich zu dem Reflexionsverhalten des Reflektors 31 und wird deshalb hier nicht weiter beschrieben.Each of the reflector inserts 46 has a rear-

Im Gegensatz zu der Leuchtvorrichtung 61 sind die Leuchtdioden 56 nun auf einem gemeinsamen, im Wesentlichen kreisförmigen LED-Träger 57 (Platine o.ä.) montiert und tauchen nicht in die zugeordnete rückseitige Ausnehmung 6 ein. Die Leuchtdioden 56 strahlen vielmehr einen überwiegenden Teil des von ihnen emittierten Lichts, insbesondere im Wesentlichen das gesamte von ihnen abgestrahlte Licht, durch die jeweilige Ausnehmung 6.In contrast to the
Durch das Gehäuse 50 und den LED-Träger 57 läuft eine Kabeldurchführung 58, welche die verdrahtete Vorderseite des LED-Trägers 57 mit einem Aufnahmeraum 59 für einen Treiber verbindet. Der hier sichtbare Teil des Gehäuses 50 ist im Wesentlichen auch als ein Kühlkörper ausgebildet.Through the
Selbstverständlich ist die vorliegende Erfindung nicht auf die gezeigten Ausführungsbeispiele beschränkt.Of course, the present invention is not limited to the embodiments shown.
So kann der Reflektor gemäß der dritten Ausführungsform auch einstückig ausgebildet sein, z.B. aus Kunststoff.Thus, the reflector according to the third embodiment may also be integrally formed, e.g. made of plastic.
Auch können die Innenseiten der Reflektorvertiefungen ineinander übergehen und eine gemeinsame Reflektorinnenseite bilden, welche mittels mehrerer Ausnehmungen beleuchtet wird.Also, the inner sides of the reflector recesses can merge into one another and form a common reflector inner side, which is illuminated by means of a plurality of recesses.
