Abstract

PURPOSE:To unnecessitate excessive fixing forces for attaching each illumination member to the illuminating device in consideration of electrical resistance by covering a conductor with a tubular body which is formed by braiding of copper wires around a core wire made of steel wire. CONSTITUTION:A conductor A is formed by covering a core wire 8 made of high tensile steel wire with a tubular body 7 formed by braiding copper wires in such a manner as to form a fabric and, since an illumination member B is to be fixed to the conductor A via a connecting terminal which has a clamp screw 12, the conductor A can be formed as one with a diameter small enough for its appearance to be inconspicuous and with a considerable length. In addition, the tubular body 7 being formed as a braided body has a large electric capacity and, when clamped and pressed by clamp screw 12 of the illumination member B, it is readily deformed to hold the illumination member B firmly. A particularly strong fixing means is thus not required.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a lighting device in which a set of two conductive wires is stretched in a room or other space, and several lighting bodies are suspended from the wires. It is.

(Conventional technology) In recent years, due to changes in indoor lighting, not only hotels and restaurants but also homes have begun to dim the entire room and instead use spotlights to illuminate ceilings, walls, dining tables, garden plants, etc. In addition, multi-lamp lighting, in which a coarse net is stretched in the space near the ceiling and small light bulbs attached to the sides of the net, create a starry sky, is becoming popular.

By the way, in addition to these devices, thin bare wires are stretched at a height close to the ceiling, and small lighting objects are suspended from these wires at appropriate intervals and energized, so that the lighting objects appear to be floating in the air at first glance. There is a lighting system. This product was originally developed in Europe and America, but has recently been studied in Japan as well.

(Problem to be Solved by the Invention) Now, in a lighting device in which a lighting body is suspended on a conducting wire made of bare wire, each lighting body cannot be directly held by the conducting wire, that is, the conducting wire is pre-illuminated. The lighting member with the attached body will be suspended.

Since this conductor is a bare wire that crosses the room, etc., the power supply is limited to low voltage, and a considerable amount of current is required to supply it to a large number of lighting objects, so the conductor is highly conductive and disconnectable. It is desirable to have a large area, but since the conductor must be inconspicuous, its thickness is limited to a certain range, and copper wire is usually used as is. There is.

However, since copper wire easily breaks if it is under strong tension, the span of its tension is narrow, and its surface has a circular cross section with a smooth surface. There were inconveniences such as the need for excessive fixing force for installation.

(Means for Solving the Problems) On the other hand, the present invention solves the above-mentioned drawbacks by configuring the above-mentioned conducting wire by enclosing a cylindrical body formed by braiding copper wire around a core wire made of m-wires. Various mounting members have been developed to overcome this problem and to make it easier to attach lighting to conductive wires.

(Embodiments of the Invention) An embodiment of the invention will be described with reference to the drawings. FIG. This figure shows each side of the lighting member B suspended from the conducting wire, and in reality, lighting fixtures of the same type are attached to the left and right set of conducting wires stretched at appropriate intervals, for example, at 1 m intervals.

The conducting wires A have a diameter of 3wn and a total length of 3 to 10m, and one end of each pair of wires is fixed to a hanger 2 installed on one wall of the room, and a transformer is installed near or integrally with this hanger 2. 3 supplies 12 volt alternating current, and the other end is connected to a hanger 4 installed on the other wall in the room.
, 5, etc., in tension. Note that this conductor IA can also be tensioned vertically as shown in FIG. 2, and in this case, a tension weight roller is provided at the lower end as shown in the same figure to keep it under tension at all times.

As is clear from FIG. 3, this conductor A is formed by providing a core wire 8 made of high-tensile steel wire in a woven cylindrical body 7 that is knitted with fine-diameter copper wire and plated with nickel. is,
Piano wire is common for this high tension, t*, and g.
For relatively short conductor wires, stranded high-tensile steel wires are used.

As shown in Fig. 1, there are various kinds of lighting members B that are suspended from the conducting wires 1 and 1 stretched in this way. Therefore, these can be attached not only to conductors stretched horizontally, but also to conductors stretched vertically or at an angle. It is formed by being attached with a reflective shade.

FIG. 4 is an exploded perspective view of a lighting member B2 in which a light bulb 10 and a reflector 11 are provided on the rod 9, and the rod 9 has a tightening screw 12 at each end for holding the conductor A. A straight pipe 15 made of brass having a connecting terminal 13 and a connecting hole 14 at the other end. The other end of ↓5 is connected to both ends of the insulating member 16, and the insulating member 16 is provided with clamping tongues 17. It is designed to stop. In this case, light bulb 1
0 is 2 for the purpose of no blackening and less decrease in luminous flux.
0-50 watt halogen bulbs are used.

Similarly, the lighting member B is for use with conductors stretched horizontally, and as shown in FIG. Each of the connecting terminals 13 has a diameter, and a connecting hole 14, 14 for attaching a light bulb is provided on the lower center surface of the insulating member 16. Similarly, the light bulb 10 is a halogen light bulb.

Furthermore, the illumination member B4 is such that its illumination angle can be adjusted not only directly below the conductor A but also to the left and right.
As shown in the figure, connection terminals 13 and 13 each having a tightening screw 12 at one end are attached to the bending rod 19 through a mounting screw 20 to a semicircular bent rod 19.19 provided with an insulating member 16 sandwiched therebetween.
It can be fixed at any position of 9. With this structure, the light bulb 1o connected to the insulating member 16 can be tilted together with the reflective shade 11 by rotating and fixing the left and right bent rods 19, 19 to one side as shown by the chain lines in the figure. Note that the light bulb 10 may also be a halogen light bulb, or only the light bulb may be attached.

(Effects of the Invention) As explained above, the present invention is configured by suspending a plurality of lighting members B from the conducting wires A stretched in parallel. The illumination member B is formed by enclosing a cylinder 7 made of copper wire knitted into a fabric, and is fixed to the conductor A via a connecting terminal 13.13 having a tightening screw 12. From, guide! The IA can be made to be thin enough to be unnoticeable in appearance and of considerable length, and the braided cylindrical body 7 has a large electric capacity, and can be tightened with the tightening screw 12 of the lighting member B. Since it deforms easily when compressed and can securely hold the illumination member B, no particularly strong fixing means is required.

As described above, the present invention makes it possible to suspend a large number of lighting members B on the left and right pairs of conducting wires A, and furthermore,
It is also possible to extend the lamps horizontally, vertically, or inclinedly, and to use lighting members B that are suitable for these conditions, making it possible to display a wide variety of illumination, which is extremely efficient.
