Description

A light fixture assembly formed by interconnected supporting pipes
This invention relates to a light fixture assembly for a room space, comprising a plurality of interconnected supporting pipes forming at least two installation channels positioned in separate parallel planes, both installation channels comprising means for installing a fluorescent tube and the connecting means thereof and a slot leading to the room space and to be covered with a solid plate or a glare shield plate.
The lighting of especially offices, shops, public localities and the like can be advantageously carried out by means of a light fixture assembly comprising interconnected supporting pipes which in addition to the lighting form an attractive detail of the interior decoration.
Each supporting pipe forms a longitudinal installation channel wherein fluorescent tubes for lighting and the connecting means thereof are installed. In small-size supporting pipes, the fluorescent tubes and the connecting means have to be installed one after another in one and the same installation channel for reasons of space, which, however, prevents the formation of a continuous light line, because the connecting means break the row of fluorescent tubes.
For the achievement of a continuous light line the supporting pipes either have to be so large in diameter that the fluorescent tube and the connecting means required thereby have space enough to be installed one upon another in the installation pipe or in a special closed connecting means space formed in the supporting pipe, or, alternatively, a special box has to be attached to the side of the supporting pipe for each connecting means. In the former case the support pipes have to be relatively thick, which makes the light fixture assembly rather clumsy in appearance, and, in addition, there remains relatively much waste space in the supporting pipes, because the connecting means are positioned at relatively large intervals in the connecting means space. With the latter structure the resultant supporting pipe is small in size but the projecting boxes for the connecting means impede considerably the streamlined shape of the light fixture assembly.
For lighting room spaces, lighting systems are known in which supporting pipes are mounted in parallel and/or in a mutually crosswise manner on two different levels. Fluorescent tubes for direct downwardly directed lighting are thereby installed in the instal¬ lation channels of the supporting pipes of the lower level, and fluorescent pipes for indirect upwardly directed ligthing in the installation channels of the supporting pipes of the higher level. A dis¬ advantage of this system, too, is that the connecting means required by the luorescent tubes prevent the formation of a continuous light line because of the space required by the connecting means between the fluorescent tubes in the small-size supporting pipes. The object of the present invention is to avoid the above disadvantages and to provide a lighting system which enables the formation of a continuous light line by means of small-size supporting pipes in said kind of lighting system which comprises installation channels in two levels for the fluorescent tubes. This object is achieved by means of a light fixture assembly according to the invention which is characterized in that a plurality of fluorescent tubes are installed in one installation channel one after another for providing a continuous light line and that the connecting means of the fluorescent tubes are in¬ stalled in the other installation channel.
The light fixture assembly according to the invention is based on the idea that the connecting means required by the fluorescent tubes installed in one installation channel are not installed in the same channel or any other special connecting means space provided merely for the connecting means in that sup- porting pipe; instead, space is "loaned" from the other installation channel for the connecting means and the connecting means are installed in this other instal¬ lation channel together with the fluorescent tubes to be installed therein. The lower installation channel, for instance, can be optionally reserved for the fluor¬ escent tubes which- are installed one after another to form a continuous light line, while all the connecting means are installed in the upper installation channel wherein there is space enough in spite of the fluores- cent tubes to be installed therein, since a continuous light line is generally not absolutely necessary in indirect and spot lighting. The supporting pipes can therefore be small in size, since no separate spaces are needed for the connecting means. Both installation channels can be positioned in separate supporting pipes or the installation channels may be positioned side by side in one and the same supporting pipe, depending on the lighting pattern to be achieved in each particular case. The invention is also concerned with a support¬ ing pipe for the light fixture assembly described above, and such a supporting pipe is characterized in that it comprises at least two separate parallel in¬ stallation channels, both comprising means for installing a fluorescent tube and its connecting means and a slot leading to a room space and to be covered with a solid plate or alternatively with a glare shield plate.
The invention will be described in the following in more detail with reference to the attached drawings, wherein
Figure 1 is a perspective view of one embodiment of a light fixture assembly according to the inven¬ tion, Figure 2 is a schematical view of the position of the separate lighting components of the assembly of Figure 1,
Figures 3 and 4 are longitudinal sectional views of two supporting pipes of the light fixture assembly at the crossing point of the pipes,
Figures 5 and 6 illustrate the cross-section of two parallel supporting pipes of the light fixture assembly and,respectively, a double supporting pipe formed thereby, Figures 7 and 8 illustrate an alternative supporting pipe for the light fixture assembly similarly as in Figures 5 and 6, and
Figure 9 illustrates a light fixture assembly assembled of support pipes according to Figure 3 and Figure 8.
The light fixture assembly shown in Figures 1 and 2 of the drawings is assembled of supporting pipes
1 formed by aluminium profile pipes having a desired length and arranged one upon another in two parallel planes in a mutually crosswise manner.
Each supporting pipe 1 comprises a tubular body
2 (Figures 3 and 4) which defines an installation channel 3 and a longitudinal slot 4. A fastening ele¬ ment 5 is provided in the installation channel for a fluorescent tube 6 or for connecting means 7 for the fluorescent tube, such as an igniter, a choke, etc. The slot is optionally covered with a glare shield plate 8 and/or a solid plate 9.
The light fixture assembly is so assembled that a plurality of fluorescent tubes are installed in the lower supporting pipe 1 one after another, whereas further fluorescent tubes are installed in the upper supporting pipes as well as the connecting means required by all the fluorescent tubes, as appears from Figure 2 in particular.
It is noted that this kind of light fixture assembly enables the installation channel of the lower supporting pipe to be wholly reserved for the fluor¬ escent tubes so as to achieve a continuous downwardly directed light line. The connecting means are divided between the upper supporting pipes and installed in desired order in the installation channels of the supporting pipes with the fluorescent tubes so that an indirect upwardly directed lighting is achieved. The lower fluorescent tubes are connected to their con¬ necting means by means of electric wires 10 which extend from one supporting pipe to another through the crossing points of the pipes, as appears from Figures 3 and 4. Figures 5 and 6 illustrate an alternative em¬ bodiment of the light fixture assembly. In this embodi¬ ment, two supporting pipes 1 positioned in parallel one upon another in the completed light fixture assembly, Figure 5, are combined into an integral supporting pipe 11, Figure 6, which comprises two separate installation channels 3. In other respects, both halves of the double supporting pipe correspond to a single support¬ ing pipe. The fluorescent tubes and their connecting means are installed similarly as described in con- nection with Figures 1 to 4. Figures 7 and 8 illustrate still another embodiment of the light fixture assembly. In this embodiment, three supporting pipes 1 positioned in parallel one upon another in the completed light fixture assembly. Figure 7, are combined into an integral supporting pipe 21, Figure 8, which comprises three separate installation channels 3. In other respects, each section of the triple supporting pipe corresponds to a single supporting pipe.
Figure 9 illustrates a light fixture assembly formed by single supporting pipes 1 and triple supporting pipes 21. Fluorescent tubes 6 only are installed one after another in the supporting pipe 1 and the same applies to the upper installation channels of the triple supporting pipes 21. All necessary connecting means 7- are installed in the lower instal¬ lation channels of the triple supporting pipes.
The drawings and the description related thereto are only intended to illustrate the idea of the inven¬ tion. In their details, the light fixture assembly according to the invention and the supporting pipe related thereto may vary within the scope of the claims.
