提供することができる．DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a lighting device, and particularly to a lighting device in which a pair of conductors are extended and a lamp is attached to an arbitrary position. [Prior Art] Conventionally, as a lighting device in which a lamp is installed at an arbitrary position by extending a pair of conductors, as shown in Figs. 6 and 7, a pair of conductors having different polarities is used. Two 1i wires 1 coated as 1i are stretched parallel to each other indoors and connected to a low voltage power source of about 12V stepped down by a down transformer, and a lamp 2 is suspended and supported between these wires 1. The mounting part 3 is locked to the electric wire and Ill for electrical connection and mechanical support, and the mounting part 3 and structural parts such as the arm 4 of the lamp 2 are used as direct conductors to supply power from each electric wire l to the lamp 2. It is known that lighting equipment has been reinstalled to make the lighting equipment more compact. In this lighting device, as shown in Fig. 7, a pair of ceiling wire mounting tools 5'' are attached to the lower surface of the ceiling and the electric wires l are stretched approximately parallel to the lower part of the ceiling, and a pair of wall wire mounting tools 5'' are installed on the lower surface of the ceiling. Install the electric wire 1 on the wall and run it approximately parallel to the ceiling between the walls, or install a pair of wall wire installation tools 5° on the ceiling and the floor, respectively, and string the electric wire 1 between the ceiling and the floor. Alternatively, you can install one ceiling wire installation tool 5 on the lower surface of the ceiling and one wall wire installation tool 5 on the wall, and stretch the electric wire between the ceiling and the wall so that they are parallel to each other. The light fixture 2 is installed between the extended IITl! A lighting device is known in which a conductor 8 is provided on opposite sides of the support 7 so as to be electrically insulated from each other, and a lamp 2 is attached to the support 7 and electrically connected to the conductor 8. [Problems to be Solved by the Invention] However, in the above-mentioned lighting device, the irradiation direction of the lamp stem is restricted by the direction of the conductor such as the electric AI 1, and if you try to irradiate in any direction, it will be difficult to There is a problem in that it is necessary to provide a flexible lamp in the lamp 2, which makes the structure complicated and expensive.The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a simple structure. An object of the present invention is to provide a lighting device that is inexpensive and has a high degree of freedom in the direction of irradiation. An even number of conductors are arranged in parallel to each other, and the conductors are connected to a power source so that the conductors located at two adjacent vertices along the outer shape of the even-numbered rectangle have different polarities, and the outer shape of the even-numbered rectangle is A lamp is attached between conductors located at two adjacent vertices along the line. [Example] Figures 1 and 2 show an example of the present invention.
The explanation below is based on the drawings. This lighting device is a stand type, and there are four lights on the top surface of the base 10.
Conductors l1 are located at each vertex of the square and are electrically insulated from each other and protrude, and the voltage is stepped down to 12V by a down transformer so that two adjacent vertices along the outer shape have different polarities.
Each is connected to a low-voltage power source of about and,
A lamp 12 is attached between a conductor 1l that is repositioned at two adjacent vertices along the outer shape. 13 is the power supply T! i&1l. FIG. 3 shows another embodiment of the present invention,
In this case, it is of the ceiling-mounted type, and the rest is the same as the previous example. 4 and 5 respectively show still other embodiments of the present invention, in which the conductor 11 is arranged at each vertex of a rhombus in the one in FIG. The conductor 1l is placed at each vertex of a regular hexagon. In this lighting refit, any adjacent 2 along the outline
If the lamp 12 is attached between the conductors 11 located at the apex, the lamp 12 can be turned on, and there is a large degree of freedom in the installation of the lamp 12, that is, in the direction of irradiation. By the way, conductor 1
If l is an odd number rather than an even number, as shown in Figure 1O, even the conductors l1 located at two adjacent vertices may have the same polarity, and even if the lamp l2 is attached, it will light up. This increases the restrictions on the degree of freedom in mounting the lamp l2, that is, in the direction of illumination. Note that the arrangement of the conductor 11 is not limited to the above-mentioned embodiment, and may be any even-numbered polygon in which the distance between adjacent vertices is equal, such as a regular even-numbered polygon, and some vertices may extend inside the outer shape. It may be something that you are. Furthermore, the conductor is not limited to a rigid body, but may also be a conductor with @ wires stretched across it, as in the conventional examples shown in FIGS. 6 and 7. [Effects of the Invention] Since the present invention is structured as described above, it is possible to provide a lighting device that has a simple structure, is inexpensive, and has a high degree of freedom in the direction of illumination.
