Tubular screen for electric fluorescent tubes or the like.

The invention relates to a tubular screen for electrical Fluorescent tubes or the like., With one in the longitudinal direction running opening for the exit of the light rays.

With the invention, a screen is to be created that it allows the electrical in a simple manner at any point on the screen in its longitudinal direction

CIl III

Establish connection of the fluorescent tube arranged in the screen with the power supply cables. In this way it should also be possible to arrange several screens in the longitudinal direction one behind the other and in them several fluorescent tubes set one behind the other without the length of the screens and the fluorescent tubes being on top of each other need to be coordinated. In this way, light strips can be used to illuminate rooms accordingly Simply assemble and assemble the spatial conditions and the desired lighting.

According to the invention, a tubular screen is proposed, which has a further longitudinally extending opening through which the interior of one in the Screen arranged, approximately U-shaped, busbars as an electrical conductor containing profile strip is open on the outside.

Preferably in the profile strip, an adapter is the bus bars, each with a fluorescent tube in the longitudinal direction of the screen slidably fitted with the bus bars in contact with contacts for the electrical connection of the busbars with the power connection cables and an adapter with the bus bars in contact Kontak- Q) th of the electrical connection.

Preferred embodiments of the invention are shown in Protection claims included. The scope of protection extends not only to the claimed individual features, but also also on their combination.

An embodiment of the invention is shown in the drawing and is described in more detail below. Show it

Pig.l a perspective view of a tubular Screen for a fluorescent tube;

2 shows a cross section through the screen according to Pig.l.

A tubular screen 10 includes on its underside an opening 11 running in the longitudinal direction through which a fluorescent tube 12 enters the interior of the screen 10 is pushed in. It is surrounded by a ref? .Ektor 13 fixed within the screen 10, which is attached to the Edges of the opening 11 is fixed in the screen 10. The space for the fluorescent tube 12 in the screen 10 is closed by a transparent light-diffusing cover plate 14 which has the tubular shape of the screen 10 completed in the area of the opening 11.

In the upper half of the interior of the screen 10 there is a U-shaped profile strip 15 which runs parallel to the tube axis of the screen 10. In this area, the screen 10 has a further opening 16 running in the longitudinal direction ₃ through which the interior of the profile strip 15 is opened to the outside of the screen 10. The profile strip 15 is arranged in the screen in such a way that the ends of its U-legs 18 facing away from its web 17 adjoin the edges of the opening 16 of the screen 10. In the present embodiment, the profile strip 15 and the screen 10 are designed as a one-piece component, they can be made of plastic, for example.

stand or be an extruded metal profile part.

In the interior of the profile strip 15, starting from the vertical legs 18, a plurality of horizontal ribs 19 ₃ 20 and 21 are arranged, the receiving spaces between them

Observe 22 and 23. The lower receiving spaces 23 are used for receiving conductor inserts 24 made of insulating material. In each ladder insert 24 there are two lengthways of the screen 10 extending busbars 25 fixedly arranged. The interior of the profile strip 15 is suitable so to accommodate adapters displaceable in the longitudinal direction of the screen, the fastening webs or the like. have for insertion into the receiving spaces 22 and on which contacts are formed which into the receiving spaces

23 engage and are pressed resiliently against the busbars 25. Such an adapter can, for example Between two suspension pendulums 26 such as pipes, chains, ropes or the like. In the area of the entry -a pipe 27 with Power connection cables 28 can be arranged in the profile strip 15 in order to establish the electrical connection of the power connection cables 28 to produce the busbars 25.

Further adapters can be arranged at any points in the longitudinal direction of the screen 10 in the profile strip 15 be, they then connect the busbars 25 electrically to the connection contacts of a fluorescent tube 12, with both the web 17 of the profile strip 15 and the reflector 13 being interrupted at the location of the adapter is. However, such an interruption is not necessary if the adapter is directly at one end of the screen 10 behind the end cap 29 is arranged.

Apart from the busbars 25, which are inserted into the profile strip 15 via the insulating conductor inserts 24, a protective conductor 30 is still in one of ribs 21
