BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminaire whose luminaire bodies can be connected together.

0003

2. Description of the Related Art In recent years, lighting fixtures to which arbitrary light control members such as louvers or baffle plates can be attached have been used. In this case, depending on the height of the louver or baffle plate,
It is necessary to change the mounting height position of the socket. For this reason, the socket is disposed on a flat plate-shaped mounting bracket, and the height position of the mounting bracket is varied.

0004

[Problem to be Solved by the Invention] However, as lighting fixtures have become thinner in recent years, when the mounting bracket for attaching the socket is placed at the highest position, there is a gap between the mounting bracket and the lighting fixture body. If the lighting fixture bodies are connected in the longitudinal direction, there are problems such as the mounting brackets interfering with the feed wiring to the adjacent lighting fixture bodies.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a lighting fixture that allows wiring to be easily routed to adjacent lighting fixture bodies even if the lighting fixture bodies are connected and are thin. With the goal.

[Configuration of the invention]

[0007]

[Means for Solving the Problems] The present invention has a lighting equipment main body in which mounting fixtures to which a plurality of sockets for connecting lamps are attached are mounted on opposite ends of a box body, and these lighting equipment main bodies are In the connectable lighting fixture, the lighting fixture body has a wire insertion portion at at least one of both ends,
The fixture has a protrusion formed between the sockets, and a wiring insertion part formed on the back side of the protrusion.

[0008]

[Operation] When connecting the lighting fixture bodies in the longitudinal direction, the lighting equipment of the present invention arranges the wiring in the wiring insertion part on the back side of the protrusion formed on the fixture, and discharges the wiring from the wire insertion part. and makes wiring easier.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the lighting fixture of the present invention will be described below with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a lighting fixture main body, and this lighting fixture main body 1 is approximately box-shaped with an opening 2 on the bottom surface as shown in FIGS. 2 and 3. As shown in FIGS. Further, around the opening 2, a contact edge 3 is bent to contact a ceiling plate or the like.

Furthermore, end plates 4 are provided at both longitudinal ends of the lighting fixture body 1, and a knockout as a wire insertion portion 5 is formed in the upper center of these end plates 4, through which a power cord, etc. is ejected. It is now possible to do so. Further, on both sides of the wire insertion portion 5, connection holes 6 for connection are formed when the lighting fixture main body 1 is connected.

Furthermore, side plates 7 are provided on both sides of the lighting fixture body 1 in the longitudinal direction, and near both ends of the side plates 7, a plurality of mounting step portions 8 are formed facing inwardly. It is formed.

A fitting 12 to which a socket 11 is attached is slidably attached between these mounting steps 8 from the center side of the lighting fixture body 1.

[0014] Also, each of the fittings 12 has a socket 1.
1 and 11 are formed, and sliding edges 14 and 14 are formed on both sides, and these sliding edges 1
The length between 4 and 14 is formed to be slightly shorter than the inner diameter of the luminaire main body 1 in the width direction. Furthermore, the mounting surface portion 13,
13 have oblong holes 15 corresponding to the sockets 11, respectively.
, 15 are perforated. And the mounting surface parts 13, 13
A protrusion 16 bent into a triangular shape is formed between them, and a wiring insertion part 17 is formed on the back surface of this protrusion 16. Furthermore, a locking protrusion 18 is formed on the back surface of the oblong hole 15 of the mounting surface portion 13 along the longitudinal portion of the oblong hole 15, as shown in FIGS. 5 and 6.

Furthermore, reference numeral 21 denotes a locking tool, and this locking tool 21 has a disc-shaped locking surface portion 22.
A plate-shaped handle part 23 is vertically formed on the upper surface, and the upper edge of the handle part 23 has a concave arc-shaped part 25 whose diameter is slightly larger than the outer arc of the fluorescent lamp 24 attached to the socket 11.
is formed. Furthermore, a locking portion 27 is formed on the back surface of the locking surface portion 22 via a cylindrical rotation shaft portion 26 . This locking part 27
The length in the longitudinal direction is shorter than the length in the longitudinal direction of the oblong hole 15 and longer than the length in the width direction.
It is shorter than the length of the oblong hole 15 in the width direction.

[0016] Reference numeral 31 denotes a reflection plate, and a fluorescent lamp 24
When installed, it is bent along the longitudinal direction so that the fluorescent lamp 24 is placed inward and expanded downward.

Next, the assembly of the lighting equipment will be explained.

First, the sliding edge 14 of the fixture 12 is slidably locked to the mounting step 8 of an arbitrary height, and the fixture 12 is attached to the lighting fixture main body 1. Further, near the center in the width direction of the lighting fixture main body 1, as shown in FIG. 2, an inverter 32 and a terminal portion 33 are arranged.

Furthermore, when attaching the reflector 31 to the fixture 12, the handle portion 23 is made parallel to the longitudinal direction of the lighting fixture body 1, and the attachment hole 34 of the reflector 31 and the fixture 1 shown in FIG.
The two oval holes 15 are communicated with each other, and the locking portion 27 is inserted therethrough. Then, rotate the locking tool 21 with the handle part 23, and
with the locking portion 27 perpendicular to the longitudinal direction of the lighting fixture main body 1.
is locked to the locking protrusion 18 to prevent rotation of the locking tool 21.

When the locking tool 21 is in this state, as shown in FIG.
It is circumscribed with a gap around the circumference of .

[0021] Therefore, the locking part 27 of the locking tool 21 is
If the rotation is not prevented by the locking protrusion 18, the arcuate portion 25 of the handle 23 will come into contact with the outer periphery of the fluorescent lamp 24, making it impossible to attach the fluorescent lamp 24 to the socket 11. Therefore, the reflector 31 is not attached half-heartedly, and the fall of the reflector 31 can be prevented.

When installing the fluorescent lamp 24, in order to obtain a shading angle of 15° and not reduce the efficiency of the lighting equipment, the radius r of the tube diameter of the fluorescent lamp 24 and the width direction x of the lighting equipment must be In order to prevent the reflection from being cut by the fluorescent lamp 24 itself, the ratio x/r needs to be 4 or more, and as shown in FIG. 8, the height position of the fluorescent lamp 24 is
From opening 2, H≧rcos 15°+(x+rsin
15°) tan 15°.

For example, in the case of a fluorescent lamp 24 whose tube diameter r is 12.5 mm, if x is 50 mm, then H is 3
It is necessary to set the value below 0 mm.

Furthermore, when the lighting fixture bodies 1 and 1 are arranged in a connected manner, as shown in FIG. can be inserted into the hole of the wire insertion portion 5 by removing the wire insertion portion 5 . Therefore, the wiring will not be caught by the fixture 12 or the like.

[0025]

Effects of the Invention According to the lighting equipment of the present invention, when connecting the lighting equipment bodies in the longitudinal direction, the wiring is arranged in the wiring insertion part on the back side of the protrusion formed on the fixture, and the electric wire is inserted. By discharging the wiring from the section to the adjacent lighting fixture main body, the wiring can be easily wired since it will not be caught by the fixture.
