Description

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

A conventional example is shown in FIG.

That is, wiring ducts 2 and 3 are laid on the ceiling 1, first and second blocks 4 and 5 containing electrical components are installed at desired positions of the wiring duct 2, and a feed line is installed between the blocks 4 and 5. The vibro is installed and the fluorescent lamp 7 is attached to the lamp socket of the block 4.5.

The internal structure of the blocks 4 and 5 is as shown in FIGS. 2 to 4 (for example, Japanese Utility Model Publication No. 55-39523). A lamp socket 18 is provided inside the bottom part, and a mounting part 19 for a vibro feed line is provided on the top part of the lamp socket 18. and ducts 2 and 3 at the upper end.
A connection plug 20 is provided for electrically and mechanically connecting to the block, and other lighting components are housed within the blocks 4 and 5.

The attachment part 19 of the feed line vibro has a groove 21 in the center,
A pin 22 crosses the groove 21, and block locking notches 24 formed at both ends of the crack 23 of the vibro are pushed into the pin 22 to lock the vibro.

25 is a lead wire for feeding.

However, when this type of lighting fixture is configured to be attached directly to a ceiling other than a wiring duct, it is necessary to provide a space between the blocks 4 and 5.

In this case, conventionally, the distance was determined by measuring using a tape measure, which had the disadvantage of poor workability.

Therefore, the purpose of this invention is to provide a lighting fixture with improved workability.

An embodiment of this invention is shown in FIGS. 5 to 17.

That is, this lighting fixture has a connector 8. Mounting base mounting bracket that constitutes the ceiling mount9. Similarly, the mounting base body 10. Pipe for feed line 11. The first and second blocks 12, 13, which have the same structure as the blocks 4, 5, have the same structure as the above-mentioned blocks 4, 5 regarding the attachment portions of the lamp socket and the feed line pipe 11. and a fluorescent lamp 14.

To explain these according to the assembly work order, first, as shown in FIG. 8, the connector 8 is attached to the ceiling 1 with wood screws 8b and connected to the electric wiring 8c in the attic.

The feed line pipe 11 is divided and has a notch 15 for attaching a mounting bracket formed at a predetermined distance from one end surface 11a, and the feed line pipe 11 is installed at both ends in the same way as the block locking notch 24. For each block 12.1
A block locking notch 16 is provided to lock the attachment portion of the feed line pipe 11 in No. 3, and a locking spring 17 of the mounting base mounting bracket 9 is removably locked in the notch 15 as shown in FIG. do.

In this state, the one end surface 11a of the pipe 11 is brought into contact with the one side surface 8a of the connector 8 as shown in FIG. Attach the metal fittings 9 to the ceiling 1 with wood screws 9b.

Next, the feed line pipe 11 is removed from the mounting base mounting bracket 9, and the mounting base body 10 is attached to the mounting base mounting bracket 9.

In this case, the downwardly cut and raised claws 10a of the mount main body 10 are engaged with the locking holes 9a at both ends of the mount fitting 9 for installation.

Also, the connection plug 1 of the first block 12 shown in FIG.
2a to the connection locking hole 8d of the connector 8 as shown in FIGS. 5 and 7 by rotating the lever 12b (FIG. 13). The locking claw 13a of the block 13 of No. 2 is attached to the mounting base body 10.
It is attached to the locking hole 10b by rotating the lever 13b (Fig. 14).

At this time, the feed line pipe 11 of each block 12.13
The relationships between the connector 8 and the block 12 and between the mount main body 10 and the block 13 are determined so that the mutual spacing between the pins 22 of the mounting portion of the feed line pipe 11 matches the mutual spacing between the notches 16 of the feed line pipe 11. .

Pass the feed line pipe 11 through the feed line pipe 11, insert both ends of the feed line pipe 11 into the holes (not shown) in the block 12.13, and pass it through the groove 21 of the mounting part 19 in the same manner as in the conventional example.
The notch 16 is engaged with the pin 22, and the first block 1
2 and the second block 13, the feed line pipe 11 is installed.

Fluorescent lamps 14 are mounted in lamp sockets (not shown) of the first block 12 and the second block 13.

In this way, since the distance between the connector 8 and the ceiling mount is set by the distance between the one end surface 11a of the feed line pipe 11 and the notch 15, it becomes easy to determine the distance between the blocks 12 and 13. Figure 15: Tortoise medium-sized multi-light development, 16th
It is possible to easily accommodate various deployment modes, such as a Y-shaped multi-light deployment as shown in the figure and a W-shaped multi-light deployment as shown in FIG.

Note that when the first block 12 and the second block 13 are attached to wiring ducts, the notches 16, 16 of the feed line pipe 11 are located at the center of each wiring duct.

As described above, the lighting fixture of this invention places the end face of the feed line pipe on the connector and locks the ceiling mount at a predetermined position from the end face of the feed line pipe, thereby increasing the distance between the connector and the ceiling mount. Since the blocks are installed after the blocks are placed, it is easy to determine the spacing, which improves work efficiency.
