In addition, suppose that the same code | symbol is attached | subjected to the site | part which is common in the site | part demonstrated in the lighting fixture 1 mentioned above, and the overlapping description is abbreviate | omitted.

  As shown in FIGS. 11 and 12, the lighting device 2 of the present invention includes a plurality of the above-described lighting fixtures 1, and the end portions in the longitudinal direction of the shades 10 are connected by the connecting means 30 (see FIG. 18). ing. As shown in FIGS. 13A and 13B, the connecting means 30 is connected to the flat first connecting member 31 provided on the shade 10 of one lighting fixture 1 and the shade 10 of the other lighting fixture 1. And a second connecting member 32 provided.

  As shown in FIG. 13 (A), the first connecting member 31 is supported by a base 31a as a fixing plate attached to the shade 10, and guides bent down to the side plate side of the shade 10 on both the left and right sides of the base 31a. It has a part 31b. The base 31a is provided with a screw hole 31c for attachment to the shade 10, and the first connecting member 31 is provided with a screw hole 31d through which the fixing bolt 33 passes. As shown in FIG. 13B, the first connecting member 31 is bent down at an obtuse angle (angle θ1) with respect to the base 31a, and the tip of the first connecting member 31 is inclined toward the adjacent shade 10 side. Yes.

  Further, as shown in FIG. 13A, the second connecting member 32 is supported by a base 32a as a fixing plate attached to the shade 10. The base 32 a is provided with a screw hole 32 b for attaching to the shade 10, and the second connecting member 32 is provided with a screw hole 32 c for the fixing bolt 33. From the viewpoint of mounting workability and the number of parts, it is desirable that the screw hole 32c of the second connecting member 32 is threaded corresponding to the fixing bolt 33.

  As shown in FIG. 13B, the second connecting member 32 is bent down at an acute angle (angle θ2) with respect to the base 32a, and the second connecting member 32 is attached to the tip of the second connecting member 32. It is inclined to the shade 10 side. It is desirable that θ1 + θ2 = 180 degrees. Further, when connecting adjacent lighting fixtures 1, it is desirable to provide a gap 34 between the first connecting member 31 and the second connecting member 32. Thereby, when the fixing bolt 33 is fastened, the force that pulls the adjacent shades 10 and 10 together is obtained by the elasticity of the first connecting member 31 and the second connecting member 32, so that a gap may be generated between the shades 10. The appearance can be improved.

  Accordingly, as shown in FIG. 13B, the fixing bolt 33 that penetrates or is screwed into the screw holes 31d and 32c of the connecting members 31 and 32 is inclined with respect to the end surface 10b and the opening surface 10c of the shade 10. become. For example, as shown in FIG. 13C, when the fixing bolt 33 is inclined 45 degrees, the component forces fy and fx of the fastening force f of the fixing bolt 33 are equal. For this reason, as shown in FIG. 14, the gap d1 between the adjacent shades 10 and 10 can be closed by the component force fx, and the step d2 between the adjacent shades 10 and 10 can be eliminated to smoothly connect. Appearance can be improved.

  In this way, since the fixing bolt 33 obliquely tightens the first connecting member 31 and the second connecting member 32 provided in the two lighting fixtures 1 and 1 to be connected, the force of pulling along the longitudinal direction of the shade 10 is increased. As a result, the possibility that a gap d1 (see FIG. 14) and a step d2 between the shades 10 and 10 adjacent to each other after construction can be reduced as compared with the conventional case, and a better appearance can be obtained. .

  As shown in FIG. 15A, when the angle θ2 of the second connecting member 32 is 45 degrees or more (that is, the angle θ1 of the first connecting member 31 is 135 degrees or less), the component force fx> minutes. Since it becomes force fy, it is preferred to close the gap d1 between the shades 10. On the other hand, as shown in FIG. 15B, when the angle θ2 of the second connecting member 32 is 45 degrees or less (that is, the angle θ1 of the first connecting member 31 is 135 degrees or more), the component force fx <minute Since it becomes force fy, priority is given to eliminating the level | step difference d2 between the shades 10. FIG.

Further, as shown in FIGS. 16A and 16B, the width of the base 31a for attaching the first connecting member 31 to the shade 10 and the width of the base 32a for attaching the second connecting member 32 to the shade 10 are set as follows. It is desirable to correspond to the inner width dimension of the top plate 10a.
Thereby, since the width | variety of the top plate 10a of the shade 10 and the width | variety of the base 32a which supports the base 31a of the 1st connection member 31 and the 2nd connection member 32 correspond, the bases 31a and 32a are a pair of shade 10 It is sandwiched between the base end portions of the side plates 10d and 10d, which are side portions, and the displacement of the connecting members 31 and 32 with respect to the shade 10 is less likely to occur.

  As shown in FIGS. 17 and 18, in the connection portion where the longitudinal ends of the adjacent lighting fixtures 1, 1 are connected by the first connection member 31 and the second connection member 32 which are connection means 30. A power supply line 3 for supplying power from one of the lighting fixtures 1, 1 adjacent to the other is wired between the shade 10 and the lamp 20 along the accommodation direction. For this reason, the feeder line 3 can be wired without being conspicuous, and the appearance can be improved and the space can be used efficiently.

Further, as shown in FIGS. 19A and 19B, an attachment plate portion 40 is provided on the inner surface of one of the shades 10 and 10 adjacent to each other, and is hung on the inner surface of the other shade 10. Has been passed. Therefore, as shown in FIG. 17, in the other luminaire 1, a gap d <b> 3 for inserting the accessory plate portion 40 is provided between the shade 10 and the lamp reflector 21.
Thus, when the gap d4 is generated between the adjacent shades 10 and 10, the accessory plate portion 40 fills the gap, so that the appearance is improved and the power supply line 3 that connects both the lighting fixtures 1 and 1 is a gap. It can be prevented from being damaged by being pinched. The accessory plate 40 can be provided on the shade 10 by integral molding. Thereby, the number of parts can be reduced and attachment can be facilitated.

  On the other hand, the attachment plate portion 40 can be provided separately from the shade 10. In this case, as shown in FIG. 20, a U-shaped cross-sectional plate 40 accommodated in the inside of the shade 10 is formed, and the U-shaped cross-section is inserted into the sub-plate 40. A connecting member 35 having a shape is formed. Screw holes 42 and 35b for fastening to the adjacent one of the shades 10 are provided at corresponding positions on the top plate 41 and 35a of the attachment plate portion 40 and the connecting member 35, and are fastened to the other adjacent shade 10. Screw holes 43 and 35c are provided correspondingly. Then, the support plate portion 40 and the connecting member 35 are disposed across the insides of both the shades 10 and 10, and are screwed. The first connecting member 31 described above can be used as the connecting member.

In addition, the lighting fixture 1 of this invention is not limited to embodiment mentioned above, A suitable deformation | transformation, improvement, etc. are possible.
For example, in the embodiment described above, the case where the cross-sectional shape of the shade 10 is rectangular is illustrated, but the lighting fixture 1 of the present invention is also applicable to other cross-sectional shapes (for example, C-shaped, U-shaped, etc.). Is possible.
In the embodiment described above, the cross-sectional shape of the shade 10 and the cross-sectional shape of the lamp 20 are similar to each other. However, the present invention is not limited to this. It can also be shaped like a letter.

  In the above-described embodiment, the case where the first connecting member 31 and the second connecting member 32 are provided separately from the shade 10 has been described. However, as shown in FIG. 10 may be provided integrally. In this case, the number of parts can be reduced.

  Furthermore, in the lighting fixture 1 and the lighting device 2 described above, a linear one is illustrated, but in addition, as shown in FIG. 22 (A), a plurality of lighting fixtures 1 on a partial arc are connected, An arcuate illumination device 2 can also be formed. Or as shown to FIG. 22 (B), it is also possible to connect the linear lighting fixture 1 at right angle.

  As described above, since the lighting device according to the present invention covers the light source, it is possible to obtain a good appearance, and it is not necessary to consider the appearance of the lamp housed in the shade, and as a lamp It is only necessary to satisfy the functions, and the overall width can be reduced. And since the fixing bolt tightens the first connecting member and the second connecting member provided in both lighting fixtures obliquely, a large amount of force is obtained along the longitudinal direction of the shade, and between the adjacent shades after construction. The possibility of creating gaps and steps is reduced compared to the conventional case, and it has the effect of obtaining a better appearance, and a plurality of lighting fixtures in which lamps that contain light sources are covered with shades are connected in series.
