Stretch to press. Then, due to the bulging of the joining portions 36, 36, the reflecting portion 35 gradually becomes a flat plate shape against the elasticity, and the joining portions 36, 36 come into contact with the side plate portions 16, 16 so as to be in close contact with each other.

Next, the mounting operation of the above embodiment will be described.

First, the upper ends of the ceiling frames 1 and 1 are sandwiched between the positioning piece 9 and the fixed piece 8 of the support 5 on the ceiling frames 1 and 1 which are previously supported by the hanging bolts from the ceiling slab. At the same time, the elastic piece portions 10, 10 are engaged with each other, and the longitudinal ends of the support body 5 are positioned and mounted so as to bridge the upper ends of the pair of ceiling frames 1, 1 facing each other.

Next, the first reflector 13 is tilted, and one side plate portion 16 of the first reflector 13 is inserted into the mounting opening 3 opened by the opposing ceiling frames 1 and 1 to form the side plate portion. The edge portions 29 of 16 are brought into contact with one ceiling frame 1 and the edge portions 29 of the end plate portions 33 are placed on the edges of the placing portion 2 of the one ceiling frame 1. And FIG.
As shown in FIG. 7, the other side plate portion 16 is rotated upward and inserted into the mounting opening 3, and as shown in FIG.
Is slid in the width direction, and as shown in FIG. 8, the edge portion 29 of the other side plate portion 16 is placed on the placing portion 2 of the other ceiling frame 1,
The first reflector 13 is inserted into the mounting opening 3.

After that, the top plate portion 15 of the first reflector 13 is fixed by screwing the screws 6 into the screw holes 7 of the supports 5 and 5 through the elongated holes 28 and 28 to make the first reflector. The body 13 is attached to the ceiling frames 1, 1 via the supports 5, 5. It should be noted that the top plate 15 has an elongated hole 2
Since 8, 28 are provided, even if the mounting positions of the supports 5, 5 to the ceiling frames 1, 1 are displaced, the positions can be easily aligned.

Next, the second reflector 14 is inserted into the first reflector 13 through the irradiation opening 13a so that the reflecting surface 30 faces downward, and the lamp is provided in the notches 37 provided at both ends of the reflector 35. socket
22 is inserted so as to project downward from the lower surface of the reflecting portion 35,
The reflection part 35 is attached by screwing the decorative screw 23 into the screw hole 24 of the socket mount 18. When the second reflector 14 is screwed, the curved reflecting portion 35 has a flat plate shape, and
The joint portions 36, 36 slide downward on the inner surfaces of the side plate portions 16, 16 of the first reflector 13, and the joint portions 36, 36 come into contact with the inner surfaces of the side plate portions 16, 16 so as to be in close contact with each other.

Then, the second reflector 14 is replaced by the first reflector 13
Assemble the luminaire main body 12 by screwing it to the support 5,
It is attached to the ceiling frames 1 and 1 by 5.

On the other hand, when the luminaire main body 12 is to be removed for maintenance and inspection of the components such as the lamp socket 22, the lighting device 26, and the terminal block 27, the operation opposite to the assembling operation is performed.

That is, after removing the decorative screw 23 and the second reflector 14 from the first reflector 13, the first reflector 13 is removed.
Remove the screws 6 and 6 for fixing 13 to the supports 5 and 5. Then, as shown in FIG. 7, the first reflector 13 is slidably moved in the width direction until the edge portion 29 of one side plate portion 16 comes into contact with one ceiling frame 1, and the other side plate portion 16 is moved. The edge portion 29 is removed from the mounting portion 2 of the ceiling frame 1. Furthermore, the outer edge of the edge portion 29 of one side plate portion 16 is brought into contact with the ceiling frame 1, and the lower end of the edge portion 29 of the end plate portion 33 is brought into contact with the tip edge of the mounting portion 2 of the ceiling frame 1. In this state, as shown in FIG. 6, the other side plate portion 16 is rotated downward and passed through the mounting opening 3 between the ceiling frames 1 and 1 to be removed.

According to the above-described embodiment, the first reflector 13 having the lamp socket 22 for mounting the fluorescent lamp 19 and the lighting device 26 for lighting the fluorescent lamp 19 attached to the side plate portion 16 of one side.
Is mounted on one ceiling frame 1 having the mounting opening 3 opened, the other side plate portion 16 is rotated downward to move the pair of ceiling frames 1, 1.
Since the mounting opening 3 between 1 is formed so as to be insertable, the fixture main body to which the conventional lamp socket 22 and the lighting device 26 are attached, the reflector and the end plate to be attached to the fixture main body can be integrally formed, and the number of parts is reduced. It can be easily removed at the time of installation work and maintenance inspection, and the cost can be reduced.

In the above embodiment, the ceiling frames 1, 1
It was explained by screwing it to the supports 5 and 5 attached to
Any supporting and fixing means such as supporting and fixing with an anchor bolt whose lower end is located in the mounting opening 3 may be used. Further, the same effect can be obtained regardless of which lamp is mounted, not limited to the one mounted with the straight tube type fluorescent lamp 19.

Although the side plate portion 16 is provided by bending both sides of the top plate portion 15 in the longitudinal direction, the top plate portion 15 and the side plate portion 16 are integrally joined by welding or the like. You can

Further, the second reflector 14 is attached to the socket mount.
Although the description is made by screwing to 18, the same effect can be obtained by any attachment method of attaching to the first reflector 13.
