(3. Connecting jig)
As shown in FIGS. 1 and 2, the connecting lighting device 100 of the present invention is further provided with a connecting jig 4 that is mounted across a plurality of lighting fixtures 10 and connects the plurality of lighting fixtures 10 to each other. I have.

  As shown in FIG. 2 in particular, the connecting jig 4 includes jig main bodies 41 and 42 straddling a plurality of instrument main bodies 1 and a locking portion 43 extending from the jig main bodies 41 and 42 toward the instrument main body 1 side. 44, and as shown in FIGS. 1 and 2, the engaging portions 43 and 44 are inserted into the fitting holes 15 provided in the fixture body 1 to connect the plurality of lighting fixtures 10 to each other. Specifically, the connecting jig 4 can be formed, for example, by punching, pressing, bending, etc. a stainless steel plate. As shown in FIG. Locking portions 43 and 44 are formed at corresponding positions and shapes.

As this connection jig | tool 4, several embodiment can be considered with the form of the lighting fixture 10 connected mutually. Specifically, as a first form, as shown in FIGS. 2A to 2C, a series connection pattern in which a plurality of instrument bodies 1 are arranged with their end faces in the longitudinal direction of the instrument bodies 1 facing each other. Can be mentioned. In the series connection pattern which is the first form, the connecting jig 4 has two adjacent instrument bodies 1 facing each other in the longitudinal direction as shown in FIGS. 2 (A) to (C). Corresponding to the position and shape of each fitting hole 15 in the case of the arrangement, the jig body 41 formed in a rectangular shape extends in a substantially U shape from both ends near the short side on the long side. Thus, the four locking portions 43 are formed.

Moreover, as a 2nd form, as shown in FIG.2 (D), the corner connection pattern which arrange | positions the end surface in the longitudinal direction of one instrument main body 1 and the side surface in the longitudinal direction of the other instrument main body 1 facing each other. Can be mentioned. In the corner connection pattern which is the second form, the connecting jig 4 is configured so that the two adjacent instrument bodies 1 are connected to the end face in the longitudinal direction of one instrument body 1 and the other as shown in FIG. One end on the long side of the jig body 42 formed in a rectangular shape corresponding to the position and shape of each fitting hole 15 when the instrument body 1 is disposed so as to face the side surface in the longitudinal direction. Are formed in a substantially U-shape and two locking portions 43 are formed, and one locking portion 44 is formed by extending the short side of the other end on the long side in an L-shape.

In the connection lighting device 100 of the present invention, as shown in FIG. 1, an illumination system by the connection lighting device 100 is configured by combining these two forms of serial connection and corner connection shown in FIG. It is possible to do. In this case, as shown in FIG. 2, the fitting hole 15 formed in the fixture body 1 of the lighting fixture 10 corresponds to both connection patterns in one form by simply changing the arrangement of the fixture bodies. be able to.

(4. Consolidated)
In order to connect a plurality of lighting fixtures 10 using these connecting jigs 4, in the case of the series connection pattern which is the first form, as shown in FIGS. The fixture main body 1 to be connected to the ceiling surface 8 or the like is arranged with the connection surface on the upper side, and the engaging portions 43 of the connection jig 4 are connected to all the fitting holes 15 provided at both ends of the fixture main body 1 to be connected. To be integrated.

On the other hand, in the case of the corner connection pattern which is the second form, as shown in FIG. 2 (D), the appliance main body 1 to be connected is arranged side by side with the connecting surface to the ceiling surface 8 and so on. Integration is performed by inserting the locking portion 43 and the locking portion 44 of the connecting jig 4 into the fitting holes 15 provided at both ends from above. In this case, as shown in FIG. 2D, the locking portion 44 formed on the short side is inserted into the rear fitting hole 15 at a position far from the other instrument body 1.

In order to irradiate light uniformly as the linking illumination device 100, it is required that the intervals between the integrated instrument bodies 1 be equal. In addition, since the expansion and contraction due to the temperature related to the light emission of the instrument main body 1 and the translucent cover 21 is greatly different, positioning accuracy in units of 1 mm is required in consideration of the expansion and contraction due to the temperature.

The external power supply line 5 is pulled out from the hole.

Next, the fixture body 1 of the connecting lighting device 100 to be installed is connected using the connecting jig 4 as described above. The appliance body 1 is temporarily fixed by positioning the attachment hole 14 of the connected appliance body 1 on the ceiling surface 8 in accordance with the suspension bolt 6 from the ceiling surface 8 and stopping the suspension bolt 6 with a nut 7. .

Further, the external power supply line 5 is pulled out from the power supply hole 13 of the instrument main body 1, and the two core wires of the external power supply line 5 are inserted into the fast connection terminal portion 11 with the feed terminal. Wiring is performed from the quick connection terminal 11 with the feed terminal to the quick connection terminal 11 with the feed terminal of the adjacent instrument body 1 using the feed hole 16 at the end of the instrument body 1. Thereby, it becomes possible to reduce the wiring of the external power supply line 5 drawn out from the ceiling surface 8. The instrument body 1 that has been temporarily fixed is fixed to the ceiling surface 8 or the like by tightening the nut 7 of the suspension bolt 6. Finally, wiring is performed from the fixture main body 1 to the light emitting unit 2, and the light emitting unit 2 is fixed by the V-shaped spring 30, thereby completing the illumination system by the connecting illumination device 100.

  As described above, in this embodiment, the fixture body 1 of the lighting fixture 10 is connected by the connecting jig 4. As a result, the linking lighting device 100 can accurately determine the positional relationship between the lighting fixtures 10, can be easily and properly attached to the ceiling surface 8, can reduce the number of man-hours for construction, and evenly distributes the light. Can be irradiated, and good design can be exhibited.
