Specifically, it is intended that the radii of curvature of the segments between an inner vertex area of the reflector element and the outer light exit opening should also increase with increasing distance from the vertex area.

- the luminaire reflector according to the invention is characterized in that the facet surfaces at least within a partial area of at least 50% of the reflection surface - based on the radial and axial extent between the bulb opening and the light exit opening - in terms of size of each at least one of its radii of curvature designed are that in each column group successive facets regularly have alternately rising and falling or falling and rising again radii of curvature. This means that the radii of curvature from inside to outside between individual directly adjacent facets become alternately larger and smaller or smaller and larger, depending on whether starting with a smaller or a larger radius. This results in each radii differences, which - analogous to a mathematical "alternating series" - alternately changing signs (+/-) have.
- the device according to the invention that-at least within a corresponding subregion of at least 50% of the outer surface-two adjacent facets directly adjacent in each column group and different facets for their radii of curvature.
- Negative surfaces are designed such that the respective smaller radius of curvature is at least 25% smaller than the respective larger radius of curvature, d. H. the smaller radius corresponds to a maximum of 75% of the larger radius. If, for example, the larger radius should be 10 mm, the smaller radius with a maximum of 7.5 mm would be predefined. With this minimum difference of 25% can in the case of the device according to the invention, d.

Description
Die vorliegende Erfindung betrifft zunächst gemäß dem Oberbegriff des Anspruchs 1 einen Leuchten-Reflektor, bestehend aus einem hohlen, schalenförmig gewölbten, und zwar insbesondere rotationssymmetrisch parabolförmigen Reflektorkörper mit einer inneren Reflexionsfläche und mit einem in Richtung seiner Längsmittelachse zwischen einer hinteren, kleineren Leuchtmittelöffnung und einer vorderen, größeren Lichtaustrittsöffnung zunehmenden Innendurchmesser, wobei die Reflexionsfläche in eine Vielzahl von strukturierten Facetten unterteilt ist, die jeweils eine zumindest in einer Flächenrichtung mit einem Krümmungsradius gewölbte Facettenfläche aufweisen, und wobei die Facetten in einer gitternetzartigen Struktur einerseits in Umfangsrichtung in konzentrischen Ringgruppen und andererseits in radialsymmetrisch zwischen der Leuchtmittelöffnung und der Lichtaustrittsöffnung angeordnete Spaltengruppen angeordnet sind.The present invention initially relates, according to the preamble of
Weiterhin betrifft die Erfindung gemäß dem Oberbegriff des Anspruchs 8 auch eine Vorrichtung zur Herstellung eines solchen Leuchten-Reflektors, bestehend aus einem Drückformkörper mit einer dem Inneren des herzustellenden Reflektorkörpers angepassten Negativkontur mit entsprechenden Facetten-Negativflächen, wobei die Facetten-Negativflächen in einer gitternetzartigen Struktur einerseits in Umfangsrichtung in konzentrischen Ringgruppen und andererseits in radialsymmetrischen Spaltengruppen angeordnet sind.Furthermore, the invention according to the preamble of

Das Dokument
Erfindungsgemäß wird dies durch einen Reflektor mit den Merkmalen des unabhängigen Anspruchs 1 bzw. durch eine Vorrichtung gemäß Anspruch 8 erreicht. Vorteilhafte Ausgestaltungen sind in den abhängigen Ansprüchen enthalten.This is achieved by a reflector having the features of the
Demnach zeichnet sich der erfindungsgemäße Leuchten-Reflektor dadurch aus, dass die Facettenflächen zumindest innerhalb eines Teilbereiches von mindestens 50 % der Reflexionsfläche - bezogen auf deren radiale und axiale Erstreckung zwischen der Leuchtmittelöffnung und der Lichtaustrittsöffnung - hinsichtlich der Größe von jeweils mindestens einem ihrer Krümmungsradien derart ausgelegt sind, dass die in jeder Spaltengruppe hintereinanderliegenden Facetten regelmäßig abwechselnd ansteigende und wieder abfallende oder abfallende und wieder ansteigende Krümmungsradien aufweisen. Dies bedeutet, dass die Krümmungsradien von innen nach außen zwischen einzelnen direkt benachbarten Facetten abwechselnd größer und kleiner bzw. kleiner und größer werden, je nachdem, ob mit einem kleineren oder einem größeren Radius begonnen wird. Daraus resultieren jeweils Radien-Differenzen, die - analog zu einer mathematischen "alternierenden Reihe" - alternierend wechselnde Vorzeichen (+/-) aufweisen. So können sich von innen nach außen z. B. jeweils ein größerer Radius und ein kleinerer Radius abwechseln. Erfindungsgemäß handelt es sich somit um einen regelmäßig wechselnden Radien-Größen-Verlauf zwischen einzelnen Facetten. Die aus den alternierend unterschiedlichen Radien resultierenden Radien-Differenzen können sich allerdings in ihren Beträgen voneinander unterscheiden, so dass es sich um qualitativ zumindest mit einem Mindestwert vorhandene Differenzen und nicht unbedingt auch um quantitativ genau definierte Differenzen handelt.Accordingly, the luminaire reflector according to the invention is characterized in that the facet surfaces at least within a partial area of at least 50% of the reflection surface - based on the radial and axial extent between the bulb opening and the light exit opening - in terms of size of each at least one of its radii of curvature designed are that in each column group successive facets regularly have alternately rising and falling or falling and rising again radii of curvature. This means that the radii of curvature from inside to outside between individual directly adjacent facets become alternately larger and smaller or smaller and larger, depending on whether starting with a smaller or a larger radius. This results in each radii differences, which - analogous to a mathematical "alternating series" - alternately changing signs (+/-) have. So can from the inside out z. B. in each case a larger radius and a smaller radius alternate. According to the invention, it is thus a regularly changing radius-size profile between individual facets. However, the radii differences resulting from the alternately different radii can differ in their amounts from one another, so that they are qualitatively at least with a minimum value existing differences and not necessarily also quantitatively exactly defined differences.
Um die alternierenden Radien-Differenzen auch bei dem fertigen gedrückten Reflektorkörper sicherzustellen, ist bei der erfindungsgemäßen Vorrichtung bevorzugt vorgesehen, dass - zumindest innerhalb eines entsprechenden Teilbereiches von mindestens 50 % der Außenfläche - jeweils zwei in jeder Spaltengruppe direkt benachbarte und hinsichtlich ihrer Krümmungsradien unterschiedliche Facetten-Negativflächen derart ausgelegt sind, dass der jeweils kleinere Krümmungsradius um mindestens 25 % kleiner als der jeweils größere Krümmungsradius ist, d. h. der jeweils kleinere Radius entspricht maximal 75 % des jeweils größeren Radius. Soll beispielswiese der größere Radius 10 mm betragen, so wäre der kleinere Radius mit maximal 7,5 mm vorzugeben. Mit dieser Mindest-Differenz von 25 % kann bei dem mit der erfindungsgemäßen Vorrichtung hergestellten, d. h. auf den erfindungsgemäßen Drückformkörper gedrückten Reflektor der alternierend steigende und fallende Radien-Verlauf reproduzierbar sichergestellt werden.In order to ensure the alternating radii differences also in the finished pressed reflector body, it is preferably provided in the device according to the invention that-at least within a corresponding subregion of at least 50% of the outer surface-two adjacent facets directly adjacent in each column group and different facets for their radii of curvature. Negative surfaces are designed such that the respective smaller radius of curvature is at least 25% smaller than the respective larger radius of curvature, d. H. the smaller radius corresponds to a maximum of 75% of the larger radius. If, for example, the larger radius should be 10 mm, the smaller radius with a maximum of 7.5 mm would be predefined. With this minimum difference of 25% can in the case of the device according to the invention, d. H. on the molded article according to the invention depressed reflector of the alternately increasing and decreasing radii profile can be reproducibly ensured.
Aus den erfindungsgemäß alternierend ihre Größe wechselnden Krümmungsradien resultiert eine sehr gute Lichtvergleichmäßigung durch eine variierende Lichtstreuung in den unterschiedlich gekrümmten Flächenbereichen der Facetten.From the curvature radii alternatingly changing their size according to the invention, a very good light uniformity results through a varying light scattering in the differently curved surface areas of the facets.

Ein erfindungsgemäßer Leuchten-Reflektor 1 besteht aus einem hohlen, schalenförmig gewölbten Reflektorkörper 2 mit einer inneren Reflexionsfläche 4. Der Reflektorkörper 2 weist einen in Richtung einer Längsmittelachse 6 von einer hinteren, kleineren Leuchtmittelöffnung 8 in radialer und axialer Richtung gesehen bis zu einer vorderen, größeren Lichtaustrittsöffnung 10 zunehmenden, jeweils senkrecht zur Längsmittelachse 6 gemessenen Innendurchmesser auf. Bevorzugt ist der Reflektorkörper 2 rotationssymmetrisch parabolförmig ausgebildet. Im Bereich der Leuchtmittelöffnung 8 kann ein nicht dargestelltes Leuchtmittel so angeordnet werden, dass das von ihr ausgesandte Licht zumindest anteilig durch Reflexion über die Reflexionsfläche 4 nach außen aus der Lichtaustrittsöffnung 10 abgestrahlt wird. Als Leuchtmittel kann mit Vorteil auch ein flächiges LED-Element in der Ebene der Leuchtmittelöffnung 8 oder parallel dazu angeordnet werden.An inventive

Bevorzugt sind allerdings die Facettenflächen 14 jeweils sphärisch gewölbt, wobei die zwei Krümmungsradien R1, R2 gleich groß sind.As already mentioned, the two radii of curvature R1, R2 of each
Erfindungsgemäß ist nun zumindest in einem Teilbereich der Reflexionsfläche 4 von mindestens 50 % - bezogen auf die axiale und radiale Flächenerstreckung zwischen den Öffnungen 8 und 10 - vorgesehen, dass die Facettenflächen 14 hinsichtlich der Größe zumindest jeweils eines ihrer Krümmungsradien R1 und/oder R2 derart ausgelegt sind, dass in Axial- und Radialrichtung zwischen der Leuchtmittelöffnung 8 und der Lichtaustrittsöffnung 10, also innerhalb jeder Spaltengruppe B, die Krümmungsradien R1 und/oder R2 zwischen den einzelnen, jeweils direkt benachbarten Facetten 12 regelmäßig alternierend differierende Größen aufweisen.

Die Angaben sind lediglich beispielhaft zu verstehen und beschränken die Erfindung nicht. Zudem beziehen sich die genannten Radien wegen der unvermeidbaren Herstellungstoleranz insbesondere auf die Drückform; der Reflektorkörper 2 kann von den genannten Radien abweichen.The statements are only to be understood as examples and do not limit the invention. In addition, because of the unavoidable manufacturing tolerance, the radii mentioned relate in particular to the spinning mold; the
Zudem muss ausdrücklich erwähnt werden, dass wegen der beschriebenen Materialumformung im Drückverfahren die Facetten-Krümmungen im Querschnitt von einer idealen Kreisbogenform abweichen können, so dass sie über die Krümmungen hinweg keine durchgehenden konstanten, einheitlichen Krümmungsradien aufweisen. Vielmehr handelt es sich mehr um unterschiedliche, unregelmäßig mit mehreren verschiedenen Krümmungsradien gekrümmte Freiformflächen, für die Krümmungsradien nicht direkt gemessen werden können, sondern durch Näherung einer Kreisbogenform entsprechend gemittelt werden müssen, um dann den Krümmungsradius des angenäherten Kreisbogens bestimmen zu können. In der Praxis werden die Krümmungsradien insbesondere wie folgt ermittelt:
- Zunächst wird der gefertigte Reflektorkörper 2 optisch dreidimensional vermessen, und zwar mit einem Messgerät, welches unter der Bezeichnung "ATOS III SO 4 M" von der Firma GOM mbH (Gesellschaft für optische Messtechnik mbH in Braunschweig) erhältlich ist. In der Ausführung SO (= small objects) ist dieses Gerät besonders zur Vermessung kleiner Objekte - und so auch für den erfindungsgemäßen Reflektor - geeignet. Es handelt sich um einen optischen 3D-Digitalisierer bzw. um eine 3D-Koordinatenmessmaschine, die durch optisches Einscannen dreidimensionale Messdaten eines Bauteils liefert. Das Messgerät basiert auf dem Triangulationsprinzip mit einem digitalen Stereo-Kamera-Aufbau. Anhand von Abbildungsgleichungen der Optiken werden für jeden Kamerapixel unabhängige 3D-Koordinaten automatisch berechnet. Dadurch werden nicht nur einzelne Punkte ermittelt, sondern es wird die ganze Bauteil-Geometrie in einer hochauflösenden Punktewolke erfasst. Das so erfasste Polygonnetz beschreibt präzise die Oberfläche und Geometrie des Bauteils. Daraus werden CAD-Daten erzeugt.
- First, the manufactured
reflector body 2 is measured optically three-dimensional, with a measuring device, which is under the name "ATOS III SO 4 M" by the company GOM mbH (Society for optical metrology mbH in Braunschweig) is available. In the version SO (= small objects), this device is particularly suitable for measuring small objects - and thus also for the reflector according to the invention. It is an optical 3D digitizer or a 3D coordinate measuring machine that provides three-dimensional measurement data of a component by optical scanning. The meter is based on the triangulation principle with a digital stereo camera setup. Using imaging equations of the optics, independent 3D coordinates are automatically calculated for each camera pixel. As a result, not only individual points are determined, but the entire component geometry is recorded in a high-resolution point cloud. The polygonal mesh thus captured accurately describes the surface and geometry of the component. From this CAD data are generated.
Zur Vermessung des erfindungsgemäßen Reflektors wird anhand der erzeugten CAD-Daten ein Schnitt durch die Mittelpunkte der Facetten 12 jeweils insbesondere in einer Spaltengruppe B gelegt, um den jeweiligen Radius R1 zu bestimmen. Wenn R1 = R2 ist, braucht R2 nicht gesondert bestimmt zu werden. In jedem Facetten-Schnitt wird durch das genannte Gerät Folgendes bewertet:
- a) Soll-Radius gemäß einem vorgegebenen 3D-CAD
- b) Gemessene Facetten-Wölbungsform (Freiformfläche)
- c) Ermittlung eines "Best-Fit-Radius" auf der gemäß b) gemessenen Wölbungsform
- a) target radius according to a given 3D CAD
- b) Measured facet-curvature shape (free-form surface)
- c) Determination of a "best fit radius" on the curved shape measured according to b)
In dem Schritt c) wird mit dem genannten Gerät automatisch - anhand einer implementierten Software - eine so genannte "Best-Fit-Annäherung" einer Kreisbogenlinie auf die gemessene Freiformkurve durchgeführt. Der "Best-Fit-Kreisbogen" wird dabei so an die ermittelte Kurvenform angenähert, dass Abweichungen im Mittel für alle Kurvenbereiche minimiert werden. Der Krümmungsradius des so angenäherten "Best-Fit-Kreisbogens" wird als Facetten-Krümmungsradius (z. B. R1) festgelegt.In step c), a so-called "best-fit approximation" of a circular arc line to the measured free-form curve is automatically carried out with the mentioned device-based on an implemented software. The "best fit circular arc" is approximated to the determined curve shape so that deviations on average for all curve areas are minimized. The radius of curvature of the so-called "best-fit arc" is set as the facet radius of curvature (eg, R1).
