Description
Es sind Auflichtbeleuchtungsvorrichtungen bekannt, die einen Träger aufweisen, auf welchem lichtemittierende Dioden ringförmig angeordnet sind. Durch die starre Anordnung der Dioden ist die Homogenität deren ausgeleuchteten Fläche bei unterschiedlichen Abständen bzw. Bildfeldern eingeschränkt. Außerdem ist die Ausleuchtung nicht beeinflußbar.Incident illumination devices are known which have a carrier on which light-emitting diodes are arranged in a ring shape. Due to the rigid arrangement of the diodes, the homogeneity of their illuminated area is limited at different distances or image fields. In addition, the illumination cannot be influenced.
Es besteht die Aufgabe, die Auflichtbeleuchtungsvorrichtung so auszubilden, daß die Ausleuchtung des Objekts gezielt beeinflußbar ist, insbesondere eine homogene Ausleuchtung bei unterschiedlichen Arbeitsabständen zwischen Vorrichtung und Objekt erzielt werden kann.The task is to design the incident light illumination device in such a way that the illumination of the object can be influenced in a targeted manner, in particular that homogeneous illumination can be achieved at different working distances between the device and the object.
Gelöst wird diese Aufgabe mit den Merkmalen des Anspruches 1. Vorteilhafte Ausgestaltungen sind den Unteransprüchen entnehmbar.This problem is solved with the features of claim 1. Advantageous embodiments can be found in the subclaims.
Ausfiihrungsbeispiele werden nachfolgend an Hand der Zeichnungen näher erläutert. Es zeigen:Examples of implementation are explained in more detail below using the drawings. They show:

Fig. 2 einen Schnitt durch die Vorrichtung nach Figur 1; Fig. 2 is a section through the device according to Figure 1;

Fig. 4 einen Schnitt durch die zweite Ausfuhrungsform; Fig. 4 is a section through the second embodiment;
Fig. 5 eine Draufsicht auf ein Leuchtfeld; Fig. 5 is a plan view of a light field;
Fig. 6 eine Seitenansicht eines Leuchtfelds und Fig. 6 a side view of a light field and
Fig. 7 eine Draufsicht auf ein Leuchtfeld mit Abdeckscheibe. Fig. 7 is a plan view of a light field with cover plate.
Bei der Ausfuhrungsform nach den Figuren 1 und 2 ist der Träger 1 tellerförmig ausgebildet und weist konzentrisch zu seinem kreisförmigen Umfang eine Öffnung 2 auf. In diese Öffnung 2 ist ein Gewindering 3 eingesetzt, mit welchem die Beleuchtungsvorrichtung am Objektiv einer Kamera befestigt werden kann. Auf dem Träger 1 sind mehrere Leuchtfelder 4 angeordnet, im gezeigten Ausführungsbeispiel handelt es sich um sechs Leuchtfelder. Die Leuchtfelder 4 sind jeweils sechseckig ausgebildet und weisen jeweils eine Bestückplatte 5 auf. Die Bestückplatten 5 sind mit Befestigungsbolzen 6 verbunden, die an ihrer dem Träger 1 zugewandten Seite eine Klemmvorrichtung 7 aufweisen. Die Bestückplatten 5 sind mit einer Vielzahl von Leuchtquellen 8 bestückt, bei denen es sich im vorliegenden Fall um lichtemittierende Dioden handelt.In the embodiment according to Figures 1 and 2, the carrier 1 is plate-shaped and has an opening 2 concentric to its circular circumference. A threaded ring 3 is inserted into this opening 2, with which the lighting device can be attached to the lens of a camera. Several light fields 4 are arranged on the carrier 1; in the embodiment shown, there are six light fields. The light fields 4 are each hexagonal and each have a mounting plate 5. The mounting plates 5 are connected to fastening bolts 6, which have a clamping device 7 on their side facing the carrier 1. The mounting plates 5 are equipped with a large number of light sources 8, which in the present case are light-emitting diodes.
Am Träger 1 sind eine der Anzahl der Leuchtfelder 4 entsprechend der Anzahl von radial verlaufenden Schlitzen 9 vorgesehen. Die Leuchtfelder 4 sind längs der Schlitze 9 verschiebbar und durch die Klemmvorrichtungen 7 in ihrere Lage längs des Schlitzes 9 festklemmbar. An der dem Träger 1 abgewandten Seite des Befestigungsbolzens 6 kann eine Abdeckscheibe 10 befestigt werden.The carrier 1 is provided with a number of light fields 4 corresponding to the number of radial slots 9. The light fields 4 can be moved along the slots 9 and can be clamped in their position along the slot 9 by the clamping devices 7. A cover plate 10 can be attached to the side of the fastening bolt 6 facing away from the carrier 1.
Die Einstellbarkeit der Leuchtfelder 4 wird durch die Doppelpfeile verdeutlicht.The adjustability of the light fields 4 is indicated by the double arrows.
Die Ausführungsform nach den Figuren 3 und 4 unterscheidet sich von derjenigen nach den Figuren 1 und 2 durch die Ausbildung des Trägers la, der gemäß dem zweiten Ausführungsbeispiel parabolisch ausgebildet ist.The embodiment according to Figures 3 and 4 differs from that according to Figures 1 and 2 by the design of the carrier la, which is parabolic according to the second embodiment.
Die Abdeckscheiben dienen der Beeinflußung der Abstrahlcharakteristik der Leuchtfelder und bestehen beispielsweise aus Filter oder Mattscheiben.The cover plates serve to influence the radiation characteristics of the light fields and consist, for example, of filters or ground glass.
Die Leuchtfelder 4 bzw. deren Leuchtquellen 8 sind elektrisch mit einer Ansteuerschaltung verbunden. Mit dieser Ansteuerschaltung können die Leuchtfelder 4 selektiv angesteuert werden. Dies ermöglicht eine Intensitätssteuerung über mehr oder weniger Leuchtfelder 4 und/oder deren Bestromung.The light fields 4 or their light sources 8 are electrically connected to a control circuit. The light fields 4 can be controlled selectively using this control circuit. This enables intensity control over more or fewer light fields 4 and/or their power supply.
Die Leuchtfelder 4 bzw. deren Leuchtquellen 8 können in Segmente unterteilt sein, die ebenfalls von der Ansteuerschaltung getrennt ansteuerbar sind. Diese Segmente können mit unterschiedlichen lichtemittierenden Dioden bestückt sein, die in unterschiedlichen Farben Licht erzeugen. Auf diese Weise lassen sich beliebige Mischfarben erzeugen.The light fields 4 or their light sources 8 can be divided into segments, which can also be controlled separately by the control circuit. These segments can be equipped with different light-emitting diodes that produce light in different colors. In this way, any mixed colors can be produced.
Durch die Ansteuerschaltung können die Leuchtfelder 4 bzw. deren Segmente zu unterschiedlichen Zeitpunkten angesteuert werden. Hierbei ist auch ein Blitzbetrieb möglich.The control circuit allows the light fields 4 or their segments to be controlled at different times. Flash operation is also possible.
Die Ausleuchtung ist somit auf vielfältige Weise nach den Erfordernissen beeinflußbar. Die Beeinflußbarkeit ergibt sich räumlich über die Positionierung der Leuchtfelder 4, räumlich und zeitlich über die Aktivierung der Leuchtflächen und/oder deren Segmente, räumlich, zeitlich und farblich über die Aktivierung der unterschiedlich bestückten Leuchtfelder und bezüglich der Intensität über die Anzahl der eingeschalteten Leuchtfelder und/oder deren Bestromung.The illumination can therefore be influenced in a variety of ways according to requirements. The influence is achieved spatially via the positioning of the light fields 4, spatially and temporally via the activation of the light surfaces and/or their segments, spatially, temporally and in terms of color via the activation of the differently equipped light fields and with regard to the intensity via the number of light fields switched on and/or their power supply.
