Description
Lampenverschalung mit Oberreflektor. Die Erfindung betrifft eine Lampen verschalung mit Oberreflektor, welche sich dadurch auszeichnet, dass über einer Licht durchlassöffnung des Oberreflektors ein Dif- fusor angeordnet ist, welcher Licht in den Raum oberhalb des Reflektors zerstreut .dringen lässt.
Fig. 1 und 2 der Zeichnung veranschau lichen zwei Ausführungsbeispiele des Erfin dungsgegenstandes.
Während bei der Ausführungsform nach Fig. 1 die eigentliche Lampenverschalung aus einer Wellenringschale a mit flachem Oberreflektor b besteht, wobei die Wellen ringschale a in einem Ringteil klar licht durchlässig, im andern, zentralen, Ringteil für diffuse Lichtaussendung ausgebildet ist, besteht nach Fig. 2 die eigentliche Lampen verschalung aus einer zum Teil klar licht durchlässigen,
zum Teil diffus wirkenden Wellenringplatte ad mit paraboloidischem Oberreflektor b'. In beiden Fällen ist die Lampe c von oben her in die Verschalung derart eingehängt, dass die direkt nach der Wellenringschale a bezw. Wellenringplatte as gerichteten Lichtstrahlen durch diffus wirkende Teile derselben hindurchtreten, während solche Lichtstrahlen, die von der Lampe nach dem Reflektor gehen,
durch dessen Vermittlung durch die klar durch- sicIttigen Teile der Schale a bezw. Platte a' hindurchgeleitet werden.
Bei beiden gezeichneten Ausführungs formen. ist der Oberreflektor b bezw. b', der zweckmässig aus Metall hergestellt ist, mit einer zentralen Lichtdurchlassöffuung d ver sehen, über der ein ringförmiger Diffusor f angeordnet ist.
Die Reflektoröffnung d ge stattet einem Teil der Lichtstrahlen den Durchtritt nach oben, wo dieselben dann durch den Diffusor f zerstreut in den Raum oberhalb des lichtundurchlässigen Reflektors gelangen, wie dies in der Zeichnung auge- .deutet ist. Dadurch erhält man eine vorzüg liche, voll ausgiebige Ausnutzung des Lichtes.
Lamp casing with top reflector. The invention relates to a lamp casing with an upper reflector, which is characterized in that a diffuser is arranged above a light passage opening of the upper reflector, which diffuser allows light to penetrate into the space above the reflector.
Fig. 1 and 2 of the drawings illustrate two exemplary embodiments of the subject matter of the invention.
While in the embodiment according to FIG. 1 the actual lamp casing consists of a corrugated ring shell a with a flat top reflector b, the corrugated ring shell a being clearly permeable to light in one ring part and designed for diffuse light emission in the other, central, ring part, according to FIG. 2 the actual lamp cladding consists of a partially clear light permeable,
partially diffuse-acting wave ring plate ad with parabolic top reflector b '. In both cases, the lamp c is suspended from above in the casing in such a way that the BEZW directly after the shaft ring shell. Wave ring plate as directed light rays pass through diffuse parts of the same, while those light rays that go from the lamp to the reflector,
through its mediation through the clearly transparent parts of the shell a respectively. Plate a 'are passed through.
In both drawn execution forms. is the top reflector b respectively. b ', which is expediently made of metal, see ver with a central light passage opening d, over which an annular diffuser f is arranged.
The reflector opening d ge equips a part of the light rays the passage upwards, where they then arrive scattered by the diffuser f into the space above the opaque reflector, as indicated in the drawing. This gives you excellent, full use of the light.
