Description
Beleuchtungskörper mit verschiebbaren Reflektorflächen. Es sind Vorrichtungen bei Beleuchtungskörpern bekannt, die eine mehr oder minder starke Lichtausbeute dadurch. ermöglichen, .b daß verschiebbare Reflektorflächen. oberhalb der Lichtquelle oder sonstwie angeordnet sind, die je nach ihrex Einstellung die Lichtstärke in einer gewollten Richtung vergrößern oder verkleinern.Lighting fixtures with sliding reflector surfaces. There are devices known for lighting fixtures that result in a more or less strong light output. allow .b that movable reflector surfaces. are arranged above the light source or in some other way, which increase or decrease the light intensity in a desired direction depending on their setting.
Bei gewissen Arten von Beleuchtungskörpern, wie z. B. bei Ständerlampen, lassen sich aus Schönheits- und technischen Gründen Vorrichtungen obiger Art nicht verwenden, ohne den Charakter des Beleuchtungskörpers zu beeinträchtigen.With certain types of lighting fixtures, such as B. for stand lamps, For aesthetic and technical reasons, devices of the above type cannot be used without affecting the character of the lighting fixture.
Die Erfindung bietet nun auch für derartige Beleuchtungskörper die Möglichkeit, Vorkehrungen zu treffen, die eine gewollte Veränderlichkeit der Lichtstärke in einer bestimmten Richtung zulassen.The invention now also provides for such lighting fixtures Possibility to take precautions that allow a deliberate variability of the light intensity allow in a certain direction.
Diese Einrichtung ist Gegenstand der Erfindung und besteht darin, daß man eine oder alle Reflektorflächen so durchbildet daß sie wie eine, Irisblende vergrößert und verkleinert werden können (vgl. Abb. i), d. h. man bildet entsprechend der Irisblende einen Irisreflektor, Dieser Irisreflektor, der sowohl von innen nach außen als auch von außen nach innen arbeitend vorgesehen werden kann, läßt sich in verschiedener Weise mit anderen reflektierenden Flächen kombinieren, wie z. B. nach Abb. 2.This device is the subject of the invention and consists in forming one or all of the reflector surfaces in such a way that they can be enlarged and reduced in size like an iris diaphragm (cf. Fig. I), i.e. H. an iris reflector is formed according to the iris diaphragm. B. according to Fig. 2.
Abb- 3 stellt eine weitere Ausnutzungsmöglichkeit dar, indein man auch den die Lichtquelle umgebenden Schirm teleskop-, jalotisie-oder rollwandartig verstellbar macht, um nach Belieben die Schirmhöhe regulieren zu können. Die Regulierung kann sich entweder auf einen Teil oder den ganzen Schirrn beziehen.Fig. 3 shows a further possibility of utilization, in which the screen surrounding the light source can also be adjusted in a telescopic, jalotisie or roll-wall-like manner in order to be able to regulate the height of the screen at will. The regulation can relate either to a part or to the whole batch.
