DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to FIGS.

Reference numeral 1 denotes an appliance body, which is formed by bending a rectangular metal plate, and has a rectangular mounting portion 5 having a mounting surface 4 on one side for mounting a ballast (electric device) 3 for lighting the light source 2. Are provided at the center in the transverse direction along the longitudinal direction, and facing portions 6 facing the ballast 3 extend from both sides in the transverse direction of the mounting portion 5, respectively. This instrument body
1 indicates that an electric wire 7 is laid along the ballast 3 on the outside of the mounting surface 4 of the mounting portion 5, and a long hole is provided along the ballast 3.
8 are provided. Specifically, the slot 8 is
The ballast 3 is provided between the wire 4 and the wiring location of the electric wire 7 over the size of the ballast 3.

The device main body 1 has two end members 9 mounted on both ends in the longitudinal direction thereof, and a housing space 11 for housing the light source 2 supported by the socket 10 mounted on the both end members 9 has an open surface. It is formed in a state where it is formed. Light emitted from the light source 2 housed in the housing space 11 is reflected toward the opening by a reflector 12 having a substantially V-shaped cross section mounted on one side of the instrument body 1 so as to cover the ballast 3. At the same time, the light is also reflected by a portion that is not concealed by the reflection plate 12 on one side of the instrument body 1.

[0012] In such a lighting fixture, even if the mounting portion 5 is installed with the other side close to the installation location, the ballast can be used.
Most of the heat generated from the mounting portion 5 is radiated toward the facing portion 6 facing the ballast 3 by extending from the mounting portion 5 and radiated from the radiated facing portion 6. Heat does not accumulate between the other surface and the installation location, heat radiation efficiency does not decrease, and a long hole 8 is provided between the mounting surface 4 and the wiring part of the electric wire 7 along the ballast 3. As a result, heat conduction to the wiring portion of the wire 7 wired along the ballast 3 is reduced, so that the wire 7 is less likely to be heated.

Further, since the long hole 8 is provided over the size of the ballast 3, heat conduction to the wiring portion of the electric wire 7 is
Since the number is further reduced, the effect that the electric wire 7 is hardly heated can be further improved.

Further, since a U-shaped portion is formed by the mounting portion 5 and the facing portion 6, the mechanical strength can be increased.

Next, a second embodiment of the present invention will be described below with reference to FIGS. The members having substantially the same functions as those of the first embodiment are denoted by the same reference numerals,
Only different points from the first embodiment will be described. In this embodiment,
Basically, it is the same as the first embodiment, except that the facing portion 6
The difference is that a plurality of through holes 13 are provided over the size of the ballast 3. In addition, the through-hole 13 may be a long hole.

In such a lighting fixture, the heat generated from the ballast 3 is radiated from the through hole 13 provided in the facing portion, and the heat radiation efficiency is further improved, so that the electric wire 7 is hardly heated. The effects of the invention of the first embodiment can be further achieved.

Further, since the through hole 13 is provided in the facing portion 6 over the size of the ballast 3, the amount of heat radiated from the through hole 13 is further increased, so that the electric wire 7 is hardly heated. The effect of becoming more can be achieved.

Next, a third embodiment of the present invention will be described below with reference to FIG. In FIG. 7, the ballast 3 is omitted. Further, members having substantially the same functions as those in the second embodiment are denoted by the same reference numerals, and only those parts different from the second embodiment will be described. The present embodiment is basically the same as the second embodiment, except that the device main body 1 is cut and raised, and a partition portion 14 for partitioning the electric wire 7 at the corner portion formed by the extension portion 6 and the mounting portion 5 is provided. What is provided is different.

In such a lighting fixture, in addition to the effect of the second embodiment, the electric wire 7 is partitioned by the partition portion 14 into the corner portion formed by the facing portion 6 and the mounting portion 5.
It is no longer sandwiched between the instrument body 1 and the reflector 12.

In the first to third embodiments, the long hole 8
Is provided over the size of the ballast 3. However, for example, when the amount of heat transferred from the ballast 3 is small, it may not be provided as long as the size of the ballast 3.

In the second and third embodiments, the through hole
Although 13 is provided over the size of the ballast 3, for example, when the amount of heat radiation from the ballast 3 is small, it is not necessary to provide the ballast 13 as long as the size of the ballast 3.

In the first to third embodiments, the electric device is the ballast 3, but is not limited to the ballast 3.

[0023]

According to the first aspect of the present invention, even if the other surface of the mounting portion is installed close to the installation location, most of the heat generated from the electric device is extended from the mounting portion and Since the radiation is radiated toward the facing portion opposite to and is radiated from the radiated facing portion, heat does not accumulate between the other surface of the mounting portion and the installation location, and the radiation efficiency does not decrease, and Since a long hole is provided along the electric device between the mounting surface and the wiring portion of the electric wire, and heat conduction to the wiring portion of the electric wire wired along the electric device is reduced, the electric wire is hardly heated. Become.

According to the second aspect of the present invention, since the long hole is provided at least over the dimensions of the electric equipment, heat conduction to the wiring portion of the electric wire is further reduced, so that the electric wire is hardly heated. Thus, the effect of the invention described in claim 1 can be further achieved.

According to the third aspect of the present invention, the heat generated from the electric equipment is radiated from the through-hole provided in the facing portion along the electric equipment, and the heat radiation efficiency is further improved, so that the electric wire is hardly heated. Therefore, the effect of the invention described in claim 1 or claim 2 can be further exhibited.

According to the fourth aspect of the present invention, since the through-hole is provided in the facing portion at least over the size of the electric equipment, the amount of heat radiated from the through-hole is further increased, so that the electric wire is heated. Thus, the effect of the invention described in claim 3 can be further enhanced.
