Description
Einrichtung an elektrischen Lampen mit Reflektoren Für indirekte Beleuchtung. Gegenstand vorliegender Erfindung ist eine Einrichtung an elektrischen Lampen mit mindestens einer Birne mit Reflektoren für indirekte Beleuchtung. Gemäss der Erfindung ist oberhalb und unterhalb der Birne je ein Reflektor in bezug auf die Birne einstellbar ,angeordnet, wobei der untere Reflektor aus teilweise lichtdurchlassenden Material, wie Porzellan, Mattglas, Prismenglas besteht. In der beiliegenden Zeichnung ist als eine beispielsweise Ausführungsform eine Decken lampe zum Teil im Schnitt dargestellt.
An einem Hängerohr 1, das in an sich bekannter Weise an einer Zimmerdecke be festigt werden kann, ist mittelst Fassung 2 eine Glühfa.denlampe lösbar angeordnet. Oberhalb der Birne 3 ist am Rohr 1 ein koni scher, glatter Reflektor 4, zum Beispiel aus emailliertem Blech, mittelst Stellring und Stellschraube 5 in der Höhenrichtung ein stellbar angeordnet. Der Reflektor 4 ist mit- telst Streben 6 am Stellring 5 befestigt. Am Reflektor 4 ist mittelst Ketten 7 ein zweiter Reflektor 8 lösbar befestigt. Dieser liegt un terhalb der Birne 3. Er ist mit Wellen vor- sehen, und kann zum Beispiel aus Porzellan, Mattglas, Prismenglas ete., bestehen.
Die Lage des Reflektors 8 in bezug auf den Glühkörper 9 der Birne 3 ist so gewählt, dass der Reflektor 8 das Licht auf den Reflektor 4 wirft, welcher die Strahlen dann seitlich ablenkt. Ein Teil des Lichtes dringt durch den Reflektor 8, so d.ass auch der Raum un mittelbar unter der Lampe belichtet ist. Das durch den Ringraum zwischen den Reflek toren 4 und 8 austretende Licht wird von der Decke aufgefangen und in den Raum zu rückgeworfen. Die Grundform des Reflektors 8 ist mindestens annähernd parabelförmig und der Lichtkörper 9 der Birne 3 liegt an nähernd im Brennpunkt, so dass verhältnis mässig viel Licht nach oben auf den Reflek tor 4 geworfen und von diesem zurückgewor fen wird.
Der Reflektor 8 kann auch ohne Wellen glatt ausgebildet sein. Statt nur einer Birne körnten auch mehrere vorgesehen sein.
Installation on electric lamps with reflectors For indirect lighting. The present invention relates to a device on electric lamps with at least one bulb with reflectors for indirect lighting. According to the invention, a reflector is arranged above and below the pear, adjustable with respect to the pear, the lower reflector being made of partially light-permeable material such as porcelain, frosted glass, prismatic glass. In the accompanying drawing, a ceiling lamp is shown in section as an example embodiment.
On a hanging tube 1, which can be fastened to a ceiling in a manner known per se, a filament lamp is detachably arranged by means of a socket 2. Above the pear 3, a conical, smooth reflector 4, for example made of enamelled sheet metal, means of adjusting ring and adjusting screw 5 in the height direction is arranged adjustable on the tube 1. The reflector 4 is attached to the adjusting ring 5 by means of struts 6. A second reflector 8 is detachably attached to the reflector 4 by means of chains 7. This is below the bulb 3. It is provided with waves and can consist of porcelain, frosted glass, prismatic glass, etc., for example.
The position of the reflector 8 in relation to the incandescent body 9 of the bulb 3 is chosen so that the reflector 8 throws the light onto the reflector 4, which then deflects the rays laterally. Part of the light penetrates through the reflector 8, so that the room is also exposed directly under the lamp. The light emerging through the annular space between the reflectors 4 and 8 is captured by the ceiling and thrown back into the room. The basic shape of the reflector 8 is at least approximately parabolic and the light body 9 of the bulb 3 is close to the focal point, so that a relatively large amount of light is thrown upwards onto the reflector 4 and is thrown back from it.
The reflector 8 can also be smooth without waves. Instead of just one pear, several could be provided.
