[Detailed description of the invention] (Field of industrial application) This invention electrically connects one or more lighting fixtures to two conductive wires arranged parallel to each other, and suspends them vertically. Lighting equipment consisting of:

(Prior Art) As shown in Fig. 9, this type of conventional technology is a device of a certain size, which has two conductors 01 arranged parallel to each other inside, and is mainly installed on the ceiling. It used Duct 02.
More specifically, there is a groove 03 on the bottom surface for plug insertion.
A joint (not shown) is used to extend the dimensions. Insert 05 into plug 04
is provided, into which the lighting fixture 06 is inserted and removed.

(Problem that the invention aims to solve) As mentioned above, in the conventional technology, firstly, the duct is fixed to the ceiling or other wall surface, so the lighting fixtures can only be laid out in a two-dimensional manner. In other words, because there were restrictions on the installation location, there was a drawback that the lighting effect was monotonous.

Secondly, it has the disadvantage that it has a large number of component parts, has a complicated structure, requires time and manpower for construction work, and inevitably increases the cost of the product.

The present invention was developed in view of the above-mentioned shortcomings of the conventional technology, and allows the installation location to be freely selected, extremely three-dimensional and diverse layouts are possible, and extremely innovative lighting effects can be obtained. The object of the present invention is to provide a very new and useful lighting equipment that is structurally advantageous and economically efficient.

(Means for Solving the Problems) In order to achieve the above object, the lighting equipment of the present invention has two conductive wires 1, at least one end of which is fixed to a fixed surface W with a fixture 4, and stretched in parallel. A transformer 2 that converts the high voltage on the primary side into a low voltage is connected to these conductive wires 1, and two current-carrying arms 23 made of a conductive material extend from the lamp part 25, and these two The lamp part 25
and a conductive wire 1 are electrically connected to each other, and the locking tool 24 has a male screw 27 integrally protruding from one end, and the conductive wire 1 is inserted into the other end. A main body 30 is provided with an insertion groove 28 that diametrically penetrates the shaft core part and is opened at the shaft end side, and the insertion groove 28 is screwed from the other end of the main body 30. It is composed of a flexible mounting device 24B consisting of a holding tool 33 for pressing the conductive wire 1 that is inserted into the groove bottom, and a nut 34 that is screwed into the male screw 27 of the main body 30, and is provided on the current-carrying arm 23. The male screw 2 inserted into the through hole 36
The nut 34 is screwed onto the end of the energizing arm 23, and the energizing arm 23 is held therebetween, so that the relative mounting angle between the main body 30 and the energizing arm 23 can be changed and fixed.

The two conductive wires 1, 1 are provided with a tension adjustable tool 5 in the middle, and are supported by support rods 49A provided with the conductive wires 1 at support portions 50A at both left and right ends.

The above-mentioned conductive wires 1, 1 may be stretched between the fixed surfaces W using fixtures 4, 4... at both ends.
Also, one end can be fixed to the ceiling W ₃ with the fixtures 4, 4, and weights 37, 37 can be attached to the other end and suspended, or one end can be fixed to the wall surface W ₁ with the fixtures 4, 4, In addition, the other end can be fixed to the floor _W4 via the transformer box 39.

The conductive wires 1, 1 can be coated wires in addition to bare wires.

(Function) When power is supplied to the lighting equipment configured as described above, the high voltage on the primary side (AC100V) is transformed into a low voltage in the transformer 2, and the conductive wire 1 is connected to the locking tool 24 and then to the current-carrying arm 23. Electricity is then applied from the other current-carrying arm 23 to the locking tool 24, then from the conducting wire 1 to the transformer 2, and the lamp is lit.

The conductive wires 1, 1 may be stretched with at least one end fixed to the fixed surface W. Therefore, the other end may be fixed to another wall surface, the other end may be suspended from the ceiling with the other end free, or the other end may be fixed to the fixed surface W. It works so that it can be installed in a variety of ways, such as between a wall or between a floor and a wall.

The specific installation work for supporting the lighting fixture 7 on the conductive wire 1 begins with the main body 30 of the flexible mount 24B.
Insert the conductive wire 1 into the insertion groove 28 from the open groove end on the shaft end side of the insertion groove 28 bored at the other end,
Next, by screwing the holding tool 33 into the insertion groove 28 from the shaft end side and pressing the conductive wire 1 against the groove bottom,
The lighting device 7 is attached to the conductive wire 1.

Further, the flexible mount 24B functions to adjust the tightness between the nut 34 and the male screw 27 of the main body, so that its relative mounting position with respect to the current-carrying arm 23 can be freely changed.

Furthermore, the bare electric wire facilitates the electrical connection of the lighting device 7, while the coated electric wire allows the covering material to vary in color, etc.

(Effects of the invention) Since the present invention is configured as described above,
This produces the following effects.

One end of the two conductive wires is fixed to a fixed surface such as a wall, ceiling, or floor using a fixture, and the wires are stretched parallel to each other, and a lighting fixture is installed on this, so a conventional duct is used. Compared to the above, it is much easier to stretch the conductive wire, and the length can be changed freely, making the construction very simple. Furthermore, the high level of safety achieved is comparable to that of the conventional method.

In addition, since one lighting equipment is completed with a minimum of transformers, conductive wires, fixtures, and lighting fixtures, the overall structure is much simpler and easier to manufacture than those that use conventional ducts. , can be provided at a low price, and further contributes to the ease of construction work.

What is noteworthy is that since the lighting fixtures are installed directly on the conductive wires, the conductive wires can be installed in any way you like, such as between walls or hanging from the ceiling. In addition to being able to freely select the installation location, there is also a variety of ways to install the installation.In other words, it can be installed anywhere in the room, in a show window, etc. It has a great deal of flexibility in how it can be installed, and can produce three-dimensional, diverse, and excellent lighting effects that cannot be achieved with conventional lighting. be effective.

Furthermore, the present invention has a flexible mount 24B, so that the current-carrying arm 23 extending from the lighting fixture 7 can be
The relative mounting position of the current-carrying arm 23 to the flexible mount 24B, which supports the conductive wire 1, can be adjusted freely around the axis of the main body 30 of the flexible mount 24B. Although it is one piece of equipment, it has the advantage of providing diversity in the direction of light irradiation from the lamps, and further expanding and improving the lighting effect.

Furthermore, the mechanism for adjusting the relative posture between the flexible mount 24B and the current-carrying arm 23 includes a through-hole 36 provided in the current-carrying arm 23, a male screw 27 of the main body 30 inserted into the through-hole 36, and a male screw 27 of the main body 30 inserted into the through-hole 36. For example, the shaft end of the current-carrying arm is inserted into one shaft end of the main body with the same axial direction. Compared to such a structure, the mechanism for adjusting the angle can be constructed more sturdily.

Then, the two conductive wires 1 are stretched in a tensioned state by a tension adjusting device 5 such as a turnbuckle, and the two conductive wires 1 in the tensioned state are held on a support rod 4.
Two conductive wires 1 are attached to the supporting parts 50A at both ends of the wire 9A.
By supporting the conductive wires 1, the mutual spacing between the two conductive wires 1 is maintained correctly as expected, and as a result, the insertion groove 28 of the universal mount 24B and the conductive wire 1 There is an advantage that the relative installation interval between the lighting device and the conductive wire is clearly shown, and the work of attaching and detaching the lighting device and the conductive wire becomes very easy.

Furthermore, if the trans box is fixed to the floor, installation of the trans box is much easier than when installing the trans box behind the ceiling or inside the wall, further improving workability.
