Description

Die Erfindung betrifft einen Scheinwerfer für Beleuchtungszwecke, insbesondere einen Scheinwerfer zur Verwendung als Werfereinheit in einem Beleuchtungssystem mit indirekter Lichtabgabe, einem sogenannten Sekundärbeleuchtungssystem, sowie ein derartiges Beleuchtungssystem. Derartige Sekundärbeleuchtungssysteme sind für die Innenraumbeleuchtung zum Beispiel aus EP 0 735 311 A1 und für die Außenbeleuchtung, z.B. EP 0 479 042 A2 bekannt. Bisherige Werferleuchten für Sekundärbeleuchtungssysteme wiesen als Lichtquellen Lampen, z.B. Hochdrucklampen, sowie einen der Lampe zugeordneten Reflektor auf, welcher das Licht der Lampe auf den Reflektor des Sekundärbeleuchtungssystems bündelte. Derartige Werferleuchten waren in der Regel voluminös und in ihrer Bauweise aufwendig.The invention relates to a headlamp for lighting purposes, in particular a headlamp for use as Werfereinheit in an illumination system with indirect light output, a so-called Sekundärbeleuchtungssystem, and such a lighting system. Such secondary illumination systems are for interior lighting, for example EP 0 735 311 A1 and for outdoor lighting, eg EP 0 479 042 A2 known. Previous lantern lights for secondary lighting systems had as light sources lamps, such as high-pressure lamps, and a lamp associated with the reflector, which the light from the lamp was focused on the reflector of the secondary illumination system. Such launcher lights were usually bulky and expensive in their design.

Es ist die Aufgabe der Erfindung, eine alternative Konstruktion eines Scheinwerfers zur Verfügung zu stellen, der insbesondere auch als Werferleuchte für ein Sekundärbeleuchtungssystem verwendet werden kann.It is the object of the invention to provide an alternative construction of a headlamp, which can be used in particular as a launcher for a secondary lighting system.

Vorteilhaft ist daher eine Konstruktion, die einfach an verschiedene Beleuchtungsaufgaben angepaßt werden kann.The invention applies both in the field of interior lighting and in the field of outdoor lighting application. Unlike headlamps for other purposes, such as Kraftfahrzeugscheinwerfem, the light-emitting characteristic of a headlamp for lighting purposes must be adapted to differently illuminating surfaces and different angles of inclination to these surfaces. Advantageous, therefore, is a construction that can be easily adapted to different lighting tasks.

Die Spiegel können um eine, zwei oder drei Achsen verschwenkt und ggf. auch linear mit einem, zwei oder drei Freiheitsgraden bewegt werden. Bei der dargestellten Ausführungsform sind die Spiegel am Rand der Reflektoreinheit 5 ortsfest und die Spiegel 12 im Inneren der Reflektoreinheit verschwenkbar, so daß die fest montierten Spiegel 10 einen äußeren Kranz um die verstellbaren Spiegel 12 bilden. Bei der dargestellten beispielhaften Ausführungsform besteht die gesamte Reflektoreinheit aus 25 Spiegelelementen, davon 16 ortsfesten Spiegeln 10 am Rand der Reflektoreinheit 5 und einer Anordnung von 3 x 3 verstellbaren Spiegeln 12 im Inneren der Reflektoreinheit 5. Anzahl und Anordnung der in den Figuren gezeigten ortsfesten und verstellbaren Spiegel 10 und 12 ist lediglich beispielhaft. Die Zahl und/oder die Anordnung der ortsfesten und verstellbaren Spiegelelemente kann, je nach den jeweiligen Anforderungen, unterschiedlich sein, ebenso wie die Reflektoreinheit ausschließlich aus ortsfesten oder ausschließlich aus verstellbaren Spiegeln bestehen kann.The throwing unit consists of several Fresnel mirrors, which in Fig. 2 10 and 12 are designated, wherein the mirror 10 are fixedly mounted and the mirrors 12 are adjustable. The mirrors can be pivoted about one, two or three axes and possibly also linearly moved with one, two or three degrees of freedom. In the illustrated embodiment, the mirrors are fixed to the edge of the reflector unit 5 and the mirrors 12 are pivotable in the interior of the reflector unit, so that the fixed mirrors 10 form an outer ring around the adjustable mirrors 12. In the illustrated exemplary embodiment, the entire reflector unit consists of 25 mirror elements, of which 16 fixed mirrors 10 on the edge of the reflector unit 5 and an array of 3 x 3 adjustable mirrors 12 inside the reflector unit 5.

The number and / or the arrangement of the fixed and adjustable mirror elements may, depending on the respective requirements, be different, as well as the reflector unit may consist exclusively of fixed or exclusively made of adjustable mirrors.

Bei dem in Fig. 1 bis 3 dargestellten Ausführungsbeispiel haben die inneren, verstellbaren Spiegel eine engbündelnde Charakteristik und die außenliegenden, ortsfesten Spiegel 12 erzeugen eine breitere Lichtverteilung als die inneren Spiegel 12.At the in Fig. 1 to 3 In the embodiment shown, the inner, adjustable mirrors have a narrow-beaming characteristic, and the outer stationary mirrors 12 produce a wider light distribution than the inner mirrors 12.

Gemäß einem vorteilhaften Aspekt der Erfindung ist den verstellbaren Spiegeln 12 jeweils ein Stellmotor 14 zugeordnet, so daß jeder Spiegel 12 über den ihm zugeordneten Stellmotor 14 individuell verschwenkt oder anderweitig verstellt werden kann. Vorteilhafterweise sind die Stellmotoren über eine drahtgebundene oder drahtlose Fernbedienung einstellbar. Die verschwenkbaren Spiegel können beispielsweise über einen PC angesteuert werden. Dies ermöglicht eine dynamische Lichtverteilung, die von einer zentralen Steuereinheit gesteuert wird.According to an advantageous aspect of the invention, the adjustable mirrors 12 are each assigned a servomotor 14 so that each mirror 12 can be individually pivoted or otherwise adjusted via its associated servomotor 14. Advantageously, the servomotors are adjustable via a wired or wireless remote control. The pivotable mirrors can be controlled, for example via a PC. this makes possible a dynamic light distribution, which is controlled by a central control unit.
