Abstract

PURPOSE: To make a support body movable in a support bar direction so that work can be conducted without disturbance of a channel or the like arranged in a ceiling for hanging a support bar by forming a slit-like fitting hole in a support body fitting portion. CONSTITUTION: A slit-like fitting holes 22 are provided at both end portions of the side face portion of a lamp socket fitting base 21 so as to face to each other. Since the support body 23 is fixed to the fitting hole 22 by a fitting screw when the support body 23 is mounted on a support bar on assembling thereof, the support body 23 can be moved inward or outward. Thereby, the support body 23 can be moved when a support bar-fitting channel disturbs luminaire fitting work, and when the support body 23 disturbs duct plumbing or the like after the luminaire fitting work, the support body 23 can be moved easily just by loosening its coupling member. Accordingly, the luminaire fitting work can be conducted without disturbance of the channel in the ceiling or facilities in the ceiling.

Reference numeral 40 denotes a supporting member mounting portion, which is a member on which the supporting member 23 is slidably mounted in the slit-shaped mounting hole 22. Therefore, the support body mounting portion 40 may be provided on the lamp socket mounting base 21 as in the embodiment, or the lamp socket mounting base may be integrally provided on the fixture body 1.

The procedure for assembling this lighting equipment will be described.

Mounting pieces 1a provided at both ends of the instrument body 1 are
The top surface portion 21a of the lamp socket mount 21 is tightened and fixed with a mounting screw 30 in the longitudinal direction.

While the lower end edge 21e of the lamp socket mount 21 attached to the fixture body 1 is brought into contact with the upper edge portion 26a of the positioning member 26 provided on the support member 23, the connecting member 32 including a mounting screw or the like is attached. The lamp socket mounting base 21 is inserted from the inside of the lamp socket mounting base 21 into the slit-shaped mounting hole 22 formed in the side surface portion 21b and screwed into the female screw 27a formed in the mounting hole 27 from the back surface of the support body 24. The support 23 is screwed and fixed to 21. The other side surface portion 21b
Similarly, the support body 23 is screwed and fixed by the mounting screw 32 in the same manner.

Next, in the same manner as in the prior art, the support 2
The apparatus main body unit 31 to which 3 is attached is placed and fixed on the support bar 12 provided adjacent to the back of the ceiling. Specifically, the upper protruding portion 1 of the support bar 12 installed on the ceiling
0, the support body 23 attached to the instrument body unit 31
When the mounting piece 25 is mounted, the substantially V-shaped hooking piece 15a of the metal pressing spring 15 having spring property is hooked and fixed to the lower surface of the upper protruding portion 10. As shown in FIG. 4, the lower end of the reflection plate 16 is placed on the upper surface of the lower protruding portion 11 of the support bar 12, and the mounting surface 16b on the upper surface of the reflection plate 16 is placed.
The mounting hole (not shown) formed on the lamp socket and the screw portion (not shown) formed on the reflection plate mounting piece 21f formed on the lamp socket mounting base 21 are aligned with each other and the mounting screw 36 is used to inward the main body of the fixture. Tighten and fix from.

However, when the support body 23 attached to the instrument body unit 31 is placed on the support bar 12, the support body 23 may hit a channel for suspending the support bar 12 or an equipment under the ceiling. Since the support body 23 is attached and fixed to the slit-shaped attachment hole 22 formed in the side surface portion 21b of the lamp socket attachment base 21 with the attachment screw 32, the support body 23 is fixed as shown in FIG. 6A. The support member 23 can be moved inward, or the support member 23 can be moved outward, as shown in FIG. 6B.

Therefore, when the lighting equipment cannot be attached due to the obstacles in the channel or the equipment in the ceiling, the mounting screws 32 are loosened from the inside of the lighting equipment to fix the support 23 as shown in FIG. It is moved inward or outward to move the support 23 to a position where there are no channels or equipment, and then the mounting screw 32 is tightened and fixed. After that, the reflector 16 is fastened and fixed to the lamp socket mount 21 with the mounting screws 36.

Therefore, the support body 23 can be easily moved by placing the instrument body unit 31 to which the support body 23 is attached on the support bar 12 and then loosening the attachment screw 32 from inside the room. It is possible to provide a lighting fixture with a simple structure that does not require the trouble of constructing the lighting fixture and has a simple structure.

The mounting screw 32 is structured so as to be tightened from the inside of the luminaire, but a slit-shaped mounting hole is provided in the support member 23, and a female screw is provided in the lamp socket mounting base 21 so that it can be mounted on the ceiling. Even when installing lighting equipment,
It produces substantially the same effect.

Although the lamp socket base is provided separately from the main body of the fixture, it may be provided integrally.

[0030]

As described above in detail, according to the present invention, since the slit holes are provided in the supporting member mounting portion and the supporting member is slidably provided in the longitudinal direction of the supporting bar, the supporting bar can be installed when the lighting fixture is installed. When the channel where the
It is possible to move the support, and when the support becomes an obstacle when piping ducts etc. after installing lighting equipment,
The support can be easily moved by simply loosening the connecting member, so the installation work of the lighting fixture can be done without being obstructed by the channel for hanging the support bar arranged in the ceiling or the equipment behind the ceiling. With a simple structure that does not hang up, it is possible to use lighting equipment that requires less construction.
