Description
Lichtsoffitte. Der Erfindungsgegenstand dient insbesondere für Schaufensterbeleuchtung. Es sind in neuerer Zeit Soffitten aus Blech oder Glas im Gebrauch, in denen die Glühbirnen für eine bestimmte Richtung fest eingestellt werden. Die Strahlung der gesamten Glühbirnen war durch die einmal gewählte Anordnung der Soffitte gegeben. Es war nicht mehr möglich, den Lichtschein der einzelnen Glühbixnen nach einmal erfolgter Anordnung der Soffitte beliebig zu richten.Light curtain. The subject of the invention is used in particular for shop window lighting. There are more recently festoons made of sheet metal or glass in use in which the Light bulbs can be fixed for a certain direction. The radiation of the entire lightbulbs was given by the once chosen arrangement of the festoon. It was no longer possible to turn off the light from the individual lightbulbs the arrangement of the festoon as desired.
Der Vorteil des Beleuchtungskörpers liegt gemäß der Erfindung darin, daß für jede Glühbirne der Soffitte Reflektorschirrne verwendet werden, welche sich nach Abb. z einzeln um die Drehachse a-b drehen können und es so ermöglichen, jeden einzelnen Lichtschein der angebrachten Glühbirnen durch Verdrehen der Schirme dahin zu richten, wo man denselben gebraucht.The advantage of the lighting fixture according to the invention is that that for each light bulb of the festoon reflector harnesses are used, which are can rotate individually around the axis of rotation a-b according to fig individual light from the attached lightbulbs by twisting the screens to judge where it is needed.
Abb. t zeigt den Gegenstand in der Seitenansicht. Abb..z stellt die Vorderansicht der Lichtsoffitte dar.Fig. T shows the object in side view. Fig..z represents the Front view of the light curtain.
Der Erfindungsgegenstand besteht aus einem Tragbalken c mit Armen d, dem Glühbirnensockel e, der Glühbirne g und dem Reflektorschirm f.The subject of the invention consists of a supporting beam c with arms d, the light bulb socket e, the light bulb g and the reflector screen f.
Der Reflektorschirm f, welcher aus Spiegelglas oder anderem Material hergestellt ist, ist an. den Armen d gelagert, welche nicht nur den Glühbirnensockel tragen, sondern auch als Drehpunkte des Refllektorschirmies f benutzt werden. Der Reflektorschirm f kann ausbalanciert werden, damit er -bei jeder Drehung in seiner Stellung verharrt, oder aber er kann an den Enden in bekannter Weise mit einer klemmenden oder reibenden Vorrichtung versehen werden, um jede Einstellung zu ermöglichen. Dadurch., daß jeder einzelne Reflektorschirm achsial um die Glühbirnen drehbar zu verstellen ist, hat man die Möglichkeit, den Lichtschein jeder einzelnen Lampe, wenn erforderlich, nach verschiedenen Richtungen zu lenken. Es ist daher leicht zu bewerkstelligen, ohne jede Veränderung an der Aufhängung der Lichtsoffitte, mit einigen Lampen die Straße oder die Decke des Schaufensters und mit anderen Lampen gleichzeitig die Auslagen im Schaufenster zu beleuchten.The reflector screen f, which is made of mirror glass or other material is made is on. the arms d supported, which is not just the bulb socket but can also be used as pivot points of the reflector screen f. Of the Reflector screen f can be balanced so that it is in its The position remains, or it can be clamped at the ends in a known manner or grinding device to enable each setting. In that each individual reflector screen can be rotated axially around the lightbulbs is adjusted, you have the option of changing the light of each individual lamp, if necessary to steer in different directions. It is therefore easy to accomplish without any change to the suspension of the light curtain some lamps the street or the ceiling of the shop window and with other lamps to illuminate the displays in the shop window at the same time.
