26 is a lid body, and this lid body 26 is
It is fitted into the unused connector part 18 to cover the connector part 18, and has a fixing pin 27 inserted into the fixing hole 20 of the connector part 18.

Reference numeral 31 denotes a connector, and the connector 31 has an isosceles triangular planar shape, and the length of the equilateral sides of this triangle is equal to the equilateral side of the triangle formed by the end plate I2 of the luminaire main body 11. is approximately equal to the length of. Moreover, especially in this embodiment, the apex angle of the triangle formed by the connector 31 is 30°. Note that both equilateral portions 32 of the connector 31 are three-dimensionally vertical planes, but these surfaces are the surfaces forming the equilateral portions 13 of the end plate 12 of the lighting fixture main body 11. It has the same shape as .

Further, electrical connector portions 33 and 34 are provided at the midpoint positions of both equilateral portions 32 of the connector 31, that is, at two positions exactly halfway between the apex portion and both ends of the bottom portion of the connector 31. .

At that time, as shown in FIG.
If both lighting fixture bodies 11 are directly brought into close contact with each other using the equilateral portions 13 of the isosceles triangular end plates 12 as guides, the angle formed by these lighting fixture bodies 11 in the connected state will be 120.
It becomes °. In addition, at this time, these lighting equipment main bodies 1
Electrical connector parts 18 of equilateral parts 13 of one end plate 12 are connected to each other via connector parts 21. This establishes an electrical connection between both lighting fixture bodies 11, and enables power supply between these lighting fixture bodies 11.

Note that the connector component 21 is built into the end plate 12 and is not exposed.

In this way, by connecting a plurality of lighting fixture bodies 11 to each other so as to form an angle of 1200 degrees, a system in which a plurality of lighting fixture bodies 11 are arranged in a hexagonal honeycomb shape is created, for example, as shown in FIG. configured. Note that at the intersection of the three lighting fixture bodies 11, the equilateral portions 13 of the end plates 12 of these three lighting fixture bodies 11 are in close contact with each other without any gaps.

Note that the unused connector portion 18 is covered with a lid 26. By the way, it is also possible to make one connector part of one end plate 12 convex like the other connector part 34 of the connector 31, but this is because the convex connector part is exposed when in use.

Thereby, electrical connection between the two shoumei instrument bodies 11 is established.

In this way, by interposing the connector 31 between the end plates 120 and the equilateral parts 13 of the pair of lighting fixture bodies 11, it becomes possible to connect both the lighting fixture bodies 11 at right angles,
For example, a plurality of lighting fixture bodies 11 forming a system arranged in a grid pattern can be used.

Furthermore, as shown in FIG. 2, it is also possible to use the 2-': connectors 31 of the same structure in a j1 connection such that their apexes coincide. At this time, the concave connector portion 33 of one C connector 31 is connected to the convex connector portion 34 of the other connecting device 31. It is also possible to connect and use three or more connectors 31. and,
For example, if the two connectors 31 connected in this way are interposed between the equilateral parts 13 of the end plates I2 of the pair of lighting fixture bodies 11, both the lighting fixture bodies 11 can be connected at an angle of 60°. This makes it possible to configure a system in which a plurality of lighting fixture bodies 11 are arranged in a regular triangle arrangement.

It is also possible to make the connector portions of both equilateral parts 32 of the connector 3I convex, but in this case, the connectors 31 cannot be connected to each other.

According to the configuration, when connecting a plurality of lighting fixture bodies 11, the angle formed by a pair of lighting fixture bodies 11 can be variably set. Moreover, even when the equilateral parts I3 of the end plates 12 of both lighting fixture bodies 11 are not brought into direct contact, these equilateral parts 1
Since the connecting tool 31 is interposed in the third opening, the reliability of the connection and the design are not impaired. At the same time, the positioning of the plurality of lighting fixture bodies 11 can be performed reliably, and the connection work can be easily performed.

Note that the apex angles of the end plate 12 of the lighting fixture body 11 and the connector 31 may be angles other than 120° and 30°, respectively.

In addition, the equilateral portions 13 of the end plates 12 of the pair of lighting fixture bodies 11
In addition to interposing the connecting tool 31 between them so that its bottom side is located on the apex side of the end plate 12, the connecting tool 31 can also be interposed so that its apex side is located on the apex side of the end plate 12. It is possible. In this case, both lighting fixture bodies 11 will be connected at an angle that is the sum of the angle formed by the apex angle of the end plate 12 and the angle formed by the apex angle of the connector 31. Furthermore, a connector portion 33.
34, the bottom side of the connector 31 is connected to the end plate 1.
It is also possible to interpose the connector 31 so that it is located on the apex side of the end plate 12, or to interpose the connector 31 so that its apex side is located on the apex side of the end plate 12.

By doing so, both lighting fixture bodies can be connected by the difference or sum of the angle formed by the apex angle of the end plate and the angle formed by the apex angle of the connector. Furthermore, even if the equal sides of the end plates are not brought into close contact directly, the connector is interposed between these equal sides, so the reliability of the connection and the design are not impaired, and the positioning of multiple lighting fixture bodies is also possible. It can be done reliably and the connection work is easy.
