Specifically, when the tip of the lock mechanism 340 is protruding, the protruding tip is inserted into the lighting duct to be fitted therein, and the plug 300 is regulated so as not to rotate with respect to the lighting duct.

Next, assembly of the lighting fixture of this embodiment will be described.
The light source module 120 is mounted on the bottom portion 111 (light source mounting portion 111a) of the lamp body 110, and the light source holder 130 is fixed to the bottom portion 111 (light source mounting portion 111a) so as to cover the light source module 120. Install.

Of the two optical lens holders 150, the flange portion 144 of the optical lens 140 is inserted into the lens holding portion 153 of one of the optical lens holders 150, and then the optical lens is inserted into the lens holding portion 153 of the other optical lens holder 150. The optical lens 140 is sandwiched by the two optical lens holders 150 so that the collar portion 144 of the 140 is inserted.

It is held to cover the light emitting surface of the module 120.

Next, the power supply unit 160 is attached, and the arm support portion 220 of the arm 200 is attached. The mounting insert portion 171 of the lamp cover 170 is inserted into the lamp cover inserting portion 113 of the lamp body 110 so that the lamp cover 170 covers the power supply unit 160 side, and the mounting portion 173 is fastened and fixed to the power supply unit 160 with a screw. .. At this time, a recess (gap) having a predetermined interval (about 1 mm to 2 mm) is formed between the lamp body 110 and the lamp cover 170. When there is a variation in the external shape caused by the difference in the material and the processing method, if the lamp body 110 and the lamp cover 170 are brought into contact with each other without a gap, the outer shape of the outer shape generated at the boundary between the lamp body 110 and the lamp cover 170 will be displayed. Since a slight step can be visually recognized, the appearance may be impaired. However, by providing a gap between the lamp body 110 and the lamp cover 170, the outer shape of the lamp body 110 and the outer shape of the lamp cover 170 can be made different. Even if there is a slight difference in size (step), it is difficult to be visually recognized, so that the aesthetic appearance can be improved. Although the gap at the boundary between the lamp body 110 and the lamp cover 170 may be widened, if the gap is widened, the gap (recess) can be easily recognized visually. Therefore, since the outer shape of the lamp body 110 and the lamp cover 170 is not continuous, it is preferable to narrow the gap in order to keep the outer shape of the lamp body 110 and the lamp cover 170 continuous.

Next, two patterns will be described regarding the work of attaching the lighting fixture 1000 to the lighting duct.

First, the first mounting method will be described with reference to FIGS. 8B and 9A.
First, the lamp 100 is rotated so that the light emitting portion of the lamp 100 is directed obliquely to the plug 300 (FIG. 8B, obliquely lower left in FIG. 9A). By doing so, the arm 200 is not hidden by the lamp 100, and the exposed portion of the arm 200 is large, so that the worker can easily hold the arm 200.

In this state, the operator grips the plug 300 with his thumb and forefinger, and slides the lock mechanism 340 on the side surface of the plug 300 with his thumb. At this time, the arm attachment portion 230 is caught on the middle finger, so that the operation of sliding the lock mechanism 340 with the thumb is facilitated.

Next, the attachment part 330 of the plug 300 is inserted into the insertion part (mounting part) of the lighting duct, the plug 300 is rotated 90 degrees, and the slide of the lock mechanism 340 is released to hold the plug 300 in the lighting duct. To be done. The plug 300 has a plug rotating shaft portion 310 that is a rotating mechanism for rotating the arm 200. However, the arm 200 is linear, and the width of the arm 200 is smaller than the diameter of the plug 300. Therefore, when the operator picks up the plug 300, the arm 200 is not so large that the plug 300 is difficult to grip, and the arm 200 is rotated so that it is not difficult to work.

Further, since the arm supporting portion 220 of the arm 200 is arranged at the position of the cylindrical outer peripheral side of the plug mounting receiving portion 231, the middle finger can be brought into contact with the plug mounting receiving portion 231, and the arm supporting portion 220 can be gripped. Can be made easier.

In addition, when the length of the arm 200 (grasping part) exposed when the lamp 100 is rotated in a direction substantially orthogonal to the arm 200 is 60 mm to 120 mm, when an operator picks the plug 300, The worker's hand does not interfere with the arm 200 and the lamp 100, and the workability is improved.

Next, the second attachment method will be described with reference to FIGS. 8(c) and 9(b).
The lamp 100 is rotated so that the arm 200 and the lamp 100 are substantially orthogonal to each other. By doing so, the arm 200 is not hidden by the lamp 100, and the exposed portion of the arm 200 is large, so that the worker can easily hold the arm 200.

In this state, the operator holds the arm support 220 and slides the lock mechanism 340 on the side surface of the plug 300 with his thumb.

Next, the attachment part 330 of the plug 300 is inserted into the insertion part (mounting part) of the lighting duct, the plug 300 is rotated 90 degrees, and the slide of the lock mechanism 340 is released to hold the plug 300 in the lighting duct. To be done. The plug 300 has a plug rotating shaft portion 310 that is a rotating mechanism for rotating the arm 200. However, the arm 200 is linear, and the width of the arm 200 is smaller than the diameter of the plug 300. Therefore, when the operator picks up the plug 300, the arm 200 is not so large that the plug 300 is difficult to grip, and the arm 200 is rotated so that it is not difficult to work.

Further, when the arm 200 is rotated so as to be substantially orthogonal to the lamp 100, the exposed portion (holding portion) of the arm 200 is widened, so that the workability of the worker to attach to the lighting duct is improved. Also, after the arm 200 is mounted on the lighting duct, the arm 200 is hidden by the lamp cover 170 and the like. Therefore, when the user looks up at the lighting fixture 1000, the exposed portion of the arm 200 is reduced by the lamp cover 170 and the like. Can be improved.

In addition, when the length of the arm 200 (grasping part) exposed when the lamp 100 is rotated in a direction substantially orthogonal to the arm 200 is 60 mm to 120 mm, when an operator picks the plug 300, The worker's hand does not interfere with the arm 200 and the lamp 100, and the workability is improved.
