Description

[Detailed explanation of the idea] This invention relates to lighting equipment.

As shown in Figure 1, the first and second blocks 1.2 containing built-in lighting components and provided with lamp sockets are attached to a wiring duct installed on the ceiling, and the first and second blocks 1.2 are connected between the first and second blocks 1 and 2. When a feed line is wired between the first and second blocks 1 and 2 in a type of lighting fixture in which a fluorescent lamp 3 is mounted, the wiring is as shown in FIGS. 2 to 4.

That is, while the locking notches 6 are formed in the splits 5 at both ends of the split pipe 4, the connecting members 7 are formed in the block 1.
is fixed internally, and a fixing bar 9 is installed in the groove 1 of this connecting member 7.

In this way, insert the end of the pipe 4 into *8, push it under the bar 4-9 using the elasticity of the split 5 or the bar 9,
The notch 6 is engaged with the bar 9, assembled, and the lead wire 10 is passed through the pipe 4.

On the other hand, when removing the pipe 4, the bar 9 is removed from the notch by rotating the pipe 4, and the pipe 4 is pulled out.

However, such a lighting device has a drawback in that when the pipe 4 is removed, the end edge 4a of the pipe 4 comes into contact with the lead wire 10 and bites and damages the lead wire 10.

That is, to explain in detail, as shown in FIG. 5a, blocks 1,
When inserting the pipe 4 between the blocks 2 and fixing it to the bar 9, it is first necessary to widen one of the blocks 1 beyond the spacing in use, as shown in FIG.

Therefore, it is necessary to increase the length of the lead wire 10 to absorb this spread, but when the pipe 4 is brought into the state shown in Fig. 5a, that is, the block 1 is placed in the correct position, the length shown in Fig. 6a is
The lead wire 10 inside the pipe 4 becomes slack a as shown in FIG.

Therefore, when this slack a is pushed into the block 1, the slack a is produced so as to protrude from the end of the split 5 in the radial direction as shown in FIG.

As a result, when the pipe 4 is rotated to remove it next time, the end edge 4a of the pipe 4 bites and damages the lead wire 10.

Therefore, an object of this invention is to provide a lighting fixture in which lead wires are prevented from being damaged.

An embodiment of this invention is shown in FIGS. 7 to 10.

That is, in this lighting device, both ends of the pipe 4 are fitted into the grooves 8 of the connecting member 11, and the locking notch 6 is locked to the fixing bar 9. A pair of tongue pieces 12 are provided on the connecting member 11, and an elastic bar 13 is inserted and supported between the tongue pieces 12, so that the lead wire 14 is guided by the elastic bar 13.

Other details are the same as in FIGS. 1 to 6.

FIG. 10a shows the operating state when the pipe 4 is inserted into the blocks 1 and 2. When the block 1 is expanded as shown in FIG. As shown in FIG. 2, the lead wire 10 is deflected and moved inside the block 1 to the same position as it would be without the elastic bar.

In FIG. 10, the lead wire 10 is pushed back into the block 1 by the elastic bar 13 in a state where the block 1 is narrowed after the pipe 4 has been inserted, so that the lead wire 10 does not slacken inside the pipe 4.

With this configuration, the lead wire 14 is connected to the elastic bar 13.
Since the position is held by the bending part 14a of the lead wire 14, the bent part 14a of the lead wire 14 can be positioned at a predetermined position in front of the pipe 4, and even if the pipe is rotated when being removed, the tip of the pipe 4 will not damage the lead wire 14.

In addition, since the lead wire 10 is pushed back into the block 1 by the elastic bar 13, it is possible to omit the work of pushing the lead wire 10 into the block 1 after inserting the pipe.
There is no need to make it longer.

It should be noted that the length of the elastic bar 13 is necessary to cause deflection, and does not prevent the internal fixation of the connecting member 11 to the block.

As described above, the lighting device of the present invention includes first and second blocks equipped with lamp sockets, lamps mounted on the lamp sockets of the first and second blocks, and the first and second blocks equipped with lamp sockets. a split pipe installed between the blocks for passing a lead wire; a locking notch formed at both ends of the split pipe; a connecting member having a groove into which both ends of the split pipe fit; a fixing bar installed in the groove of the connecting member to lock the locking notch of the split pipe; and a fixing bar having both ends fitted with the connecting member. a pair of pipes disposed in front of the end of the divided pipe and inside the first and second blocks, the locking notch being fitted in the groove of the pipe and the locking notch being locked to the fixing bar; and an elastic bar that is inserted and supported between these tongue pieces to guide the lead wire passing through the divided pipe, so that the lead wire is not damaged when the pipe is attached or detached as in the conventional case. This has the effect of eliminating the need to lengthen the lead wire and eliminating the need to push the lead wire into the block after inserting the pipe.
