BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture in which fixture bodies using straight tube lamps can be connected continuously in the longitudinal direction.

0003

2. Description of the Related Art As a lighting fixture of this type, for example, the fixture structure described in Japanese Utility Model Publication No. 63-26885 is known.

[0004] In this lighting fixture, at both ends of the fixture body,
A socket attachment part for attaching a lamp socket is extended, and a notch is provided on the side of this attachment part to form a step-like part that can be combined with an adjacent appliance main body.

[0005] By combining the stepped portions at the ends of the appliance bodies and connecting a plurality of appliance bodies continuously in the longitudinal direction, the ends of the straight tube lamps overlap and the appliance bodies This prevents the connected parts from becoming dark, and makes the illumination uniform in the connecting direction.

[0006] Such lighting equipment is used for indirect lighting. In this indirect lighting, for example, a support body having a raised part rising upward at its tip is provided protruding from the wall surface, a plurality of fixture bodies are installed in a connected state on the support body between the wall face and the raised part, and , by lighting the straight tube lamp,
Provides indirect lighting by illuminating walls and ceilings.

[0007]

[Problems to be Solved by the Invention] However, as mentioned above, when a plurality of instrument bodies are connected and installed on a support,
If a fixture located in the middle has a lighting failure, only the defective fixture is taken out from the support and inspected and repaired. To remove this defective device, the step-like parts at both ends of the device body are combined with the adjacent device bodies, so by pulling the device body upward while keeping it parallel, the defective device can be removed from between the adjacent device bodies. Only the main body of the instrument can be taken out. Note that the instrument main body is attached to the connected state by following the procedure reverse to the procedure used for taking it out.

[0008] Also, if there is a truss or the like above the instrument body that supports the support, some of the instrument bodies have the ridges above, so
It is difficult to pull up this instrument body directly upward. In such a case, pull one end of the instrument body above the end of the adjacent instrument body, move it in this state directly above the adjacent instrument body, and then lift the other end of the instrument body upward. The main body of the device can be removed by pulling it out from the bottom. In addition, attach the main body of the instrument to the connected state by following the procedure opposite to the one used for removal.

However, it is difficult to attach the instrument body by pulling the instrument body upward from the side of the rod or moving it laterally, and the angular end of the other end of the instrument body does not touch the neighboring instrument. It easily gets caught on the main body, takes time to attach to the main body, and is not easy to maintain.

The present invention has been made in view of the above-mentioned problems.The present invention is made by lifting one end of the main body of the main body and keeping the other end in contact with the installation surface, and then inserting the main body of the main body from the side of an obstacle such as a ladder. The object of the present invention is to provide a lighting fixture that is easy to maintain by allowing one end of the fixture body to be easily moved up and down when installed, and also to be able to move smoothly on the installation surface. .

[Configuration of the invention]

0012

[Means for Solving the Problems] The present invention provides a lighting fixture in which fixture bodies having lamp sockets at both ends to which straight tube lamps are connected can be connected continuously in the longitudinal direction. The end portion is provided with an inclined portion on the lower surface of at least one of the end portions, the outer end side of which is inclined upward.

[0013]

[Operation] According to the present invention, adjacent instrument bodies can be connected by abutting their respective ends.

[0014] Furthermore, since a sloped portion is provided on the lower surface of the end of the device body, the outer end side slopes upward, so that when one end side of the device body is lifted up and the sloped portion of the other end is in contact with the installation surface, it is possible to place a piece of wood such as a piece of wood. When attaching the instrument body from the side of an obstacle, it is easy to move one end of the instrument body up and down, and
Movement on the installation surface becomes smoother, making it easier to attach the instrument body.

There is. In the vicinity of both ends of the side plate portions 21 and 22, locking dowels 23 that can be removably inserted into the fitting holes 14 of the chassis 2 are provided so as to protrude toward the inner surface.

Next, the operation of this embodiment will be explained.

The lighting equipment of this embodiment is used for indirect lighting, and in this indirect lighting, for example, a support body having a rising part rising upward at the tip is provided protruding from the wall surface, and the wall surface and the rising part are connected. A plurality of appliance bodies 1 are connected and installed on a support between the lamps and the lamps are turned on to indirectly illuminate the walls and ceiling.

As shown in FIG. 3, the plurality of instrument bodies 1 connected and installed on the support body are arranged so that the ends of the adjacent instrument bodies 1 are connected to each other by the socket mounting portions 7a, 7b and the notches 8a, 8b.
are alternately combined and arranged on a straight line.

[0025] By connecting the straight tube type lamp 31 between the opposing lamp sockets 6 of each appliance main body 1,
The ends of the straight tube lamps 31 of both adjacent appliance bodies 1 overlap. Therefore, when the straight tube lamp 31 is turned on, uniform illuminance can be obtained in the connecting direction without darkening at the connecting portion of the appliance main body 1.

By the way, as mentioned above, if a plurality of appliance bodies 1 are connected and installed on a support and an appliance located in the middle becomes defective in lighting, only the defective appliance body 1 is placed on the support. Take it out and inspect and repair it.

[0027] In order to take out the defective instrument body 1, by pulling the instrument body 1 upward in a parallel state, only the defective instrument body 1 can be taken out from between the instrument bodies 1 on both sides. In addition, in order to reinstall the instrument body 1 after inspection and repair, the instrument body 1 must be
It can be installed by inserting it between the instrument bodies 1 on both sides while keeping it in a parallel state.

[0028] In addition, when there is a support support member above the instrument main body 1 and it is difficult to pull the instrument main body 1 upward, the first method for removing the instrument main body 1 is to use the socket mounting member 4 of the instrument main body 1. One end is pulled up above the adjacent end of the instrument main body 1. At this time, since the inclined part 19 is provided on the lower surface of the socket attachment part 7b on the other end side of the instrument body 1, the fulcrum position in contact with the support of the instrument body 1 is located at the mounting base 16 of the end member 4. The outer end is located on the center side of the instrument body 1, and can be easily pulled up with a relatively light force compared to the case where the fulcrum position is at the end.

Next, one end of the instrument main body 1 is moved to an area directly above the adjacent instrument main body 1 while being pulled up, and the other end of the instrument main body 1 is pulled out from under the rod or the like. At this time, since the inclined portion 19 can smoothly slide on the installation surface of the support body, the instrument main body 1 can be easily pulled out.

[0030] Then, the defective instrument main body 1 can be taken out next to the wood.

[0031] To reinstall the instrument body 1 after inspection and repair, place the other end of the instrument body 1 on the installation surface of the support body and place it on the underside of a piece of wood, etc. It is inserted from the side and combined with the adjacent end of the instrument body 1. Also at this time, since the inclined portion 19 on the other end side of the instrument main body 1 can slide smoothly on the installation surface of the support body, the installation work can be easily carried out.

[0032] Then, one end side of the instrument main body 1 is moved downward and the one end side of the instrument main body 1 is combined with the end of the adjacent instrument main body 1.

[0033] In this manner, even when a plurality of instrument bodies 1 are connected, the required instrument body 1 can be easily attached.

Note that between the chassis 2 and the reflection plate 5,
It houses terminal blocks, discharge lamp ballasts, etc. These devices vary in size depending on the type; for example, a discharge lamp ballast with a dimming function is larger than a ballast without a dimming function. In such a case, the locking dowel 2 of the reflecting plate 5
3 and the upper and lower fitting holes 14 of the chassis 2 can be selected to accommodate the size of the equipment to be accommodated.

Further, in the above embodiment, the sloped portion 19 is provided at the other end of the instrument main body 1. However, for example, a structure in which the end members 4 are attached to both ends of the instrument main body 1 may be adopted. The inclined portions 19 may be provided at both ends.
In this case, the device can be attached or detached by pulling up either end of the device body 1.

Furthermore, in the embodiment described above, the inclined part 19 was provided on the lower surface of the socket attachment part 7b of the end member 4, but the present invention is not limited to this embodiment. Similar effects can be obtained by protruding the end of the chassis in the longitudinal direction to provide a socket mounting part and forming a sloped part on the lower surface of the socket mounting part.

[0037]

Effects of the Invention According to the present invention, since a sloped portion whose outer end side slopes upward is provided on the lower surface of at least one end of the device body, one end side of the device body can be lifted and the sloped portion on the other end side can be installed. When attaching the instrument body from the side of an obstacle such as a pole while it is in contact with a surface, one end of the instrument body can be easily raised and lowered, and it can be moved smoothly on the installation surface. , the attachment work of the instrument body can be easily performed, and maintainability can be facilitated.
