Description

[Detailed description of the invention] This invention relates to a V-shaped inverted Fuji-shaped lighting fixture that is directly attached to the ceiling.

Conventionally, the V-shaped inverted Fuji-shaped lighting fixture 1, which is directly attached to the ceiling A as shown in Figs. After that, reflector hat 3
The square holes 4 provided at the four corners of the socket fittings 5 of the instrument body 2
into the lamp socket 6 attached to the reflector shade 3.
Insert the decorative screw 8 through the through hole T drilled in the
The reflective shade 3 is fixed to the fixture body 2 by screwing into the screw hole 9 of the socket fitting 5, and finally the lamp socket 6 is fixed.
I was trying to install a fluorescent tube on it.

However, since this type of lighting fixture 1 is directly attached to the ceiling A, in order to fix the reflective shade 3 to the fixture body 2 using the method described above, after fitting the reflective shade 3 to the fixture body 2,
The disadvantage is that it is difficult to attach the reflective shade 3 to the appliance body 2 because it is necessary to secure the reflective shade 3 to the appliance body 2 with decorative screws 8 while supporting the reflective shade 3 by hand to prevent it from falling due to its own weight. was there.

In addition, when fixing the reflector 3 to the appliance main body 2 by the above method, the width of the square hole 4 formed in the reflector 3 should be considerably larger than the width l of the lamp socket 6, taking into account the inclination angle of the lamp socket 6. Since the reflective shade 3 is fixed to the fixture main body 2, a gap remains between the lamp socket 6 and the square hole 4, which is unsightly in terms of appearance.

This invention has been developed to improve and eliminate the above-mentioned drawbacks of the conventional art, and the invention will be explained below according to the embodiments shown in the drawings.

In Fig. 3, 20 is a U-shaped instrument body;
Reference numeral 21 denotes a socket fitting having lamp sockets 22 on both sides, and the socket fittings 21 are formed with elasticity so that the lamp sockets 22 can move inward. 21a includes the instrument body 20
A protruding claw piece 24 that fits into a hole 23 provided in the side wall 20a is provided.

Note that the socket mounting portion 21d is located at the bottom of the side wall 21a at approximately V.
This socket mounting part 2? Attach the lamp socket 22 to d.

The installation of the socket fitting 21 to the appliance body 20 is as follows:
The claw piece 24 of the socket fitting 21 is inserted into the hole 23 of the instrument body 20.
After fitting and positioning the socket fitting 21, the flat plate part 20b of the device main body 20 and the flat plate part 21b of the socket fitting 21 are screwed together, and the socket fitting 21
The lamp socket 22 is prevented from moving inward due to the elasticity of the socket metal fitting 210.

In addition, the flat plate part 20b of this instrument main body 20 and the socket fitting 2
A glow starter socket (not shown) may be simultaneously screwed to the screwed portion of the first flat plate portion 21b.

Reference numeral 25 denotes a screw hole which is screwed into a decorative screw 26 formed in the socket fitting 21. For example, a metal fitting other than the socket fitting 21 may be provided separately and provided therein.

2T is a reflective shade with an approximately V-shaped inverted Fuji-shaped cross section that is attached to the appliance body 20, 28 is a square hole formed in the four corners of the reflective shade 27 to fit with the lamp socket 22, and 29 is also a reflective shade 2T.
These are through-holes for inserting decorative screws 26 drilled at the four corners of the square hole 28, and the outer shape of the square hole 28 is made to approximately match (slightly larger) the outer shape of the lamp socket 22.

In the above configuration, assemble the lighting equipment according to this invention,
To fix the reflector 27 to the lighting fixture 20, first attach the socket fittings 21 to both ends of the fixture main body 20 by engaging the claw pieces 24 in the holes 23, as shown in FIG. The appliance main body 20 is directly attached to a predetermined location on the ceiling A, and wiring work is performed.

Next, as shown in FIG. 4, after fitting one of the square holes 28 of the reflector shade 2T into one lamp socket 22 of the socket metal fitting 21, the lamp socket 22 is inserted into the socket metal fitting 210. It is moved in the direction of the arrow against the elastic force, and the other square hole 28 is fitted into the other lamp socket 22.

If the square hole 28 of the reflector shade 27 is fitted into the lamp socket 22 in this way, the lamp socket 22 will tend to move in the direction of the arrow ■ due to the elasticity of the socket metal fitting 210, and the side wall of the lamp socket 22 will move into the square hole of the reflector shade 270. Since it is in pressure contact with the inner periphery of the reflector 28, even if the reflector 27 is removed from the reflector 27, the reflector 27 is held below the instrument body 20 as shown in FIG. 4C.

In this state, as shown in FIG.
5, the reflector 21 is securely fixed to the fixture main body 20 with decorative screws 26, and finally the fluorescent tube is attached to the lamp socket 22, completing the assembly of the lighting fixture.

As explained above, according to this invention, when fixing the reflective shade to the fixture body using decorative screws, the reflective shade can be held at the bottom of the fixture body by fitting the square hole of the reflective shade into the lamp socket. Therefore, the reflective shade can be fixed to the lighting body with decorative screws without having to manually prevent the reflective shade from falling, which is the case with conventional lighting equipment of this type.

In addition, in the lighting fixture of this invention, the square hole drilled in the reflective shade is made to approximately match the external shape of the lamp socket, so after the reflective shade is fixed to the fixture body, the space between the square hole of the reflective shade and the lamp socket is It is preferable in terms of appearance since no gaps are formed between the two.

Furthermore, since the socket fitting is attached to the device body by engaging the convex claw piece with the hole, a slight gap is formed between the side wall of the socket fitting and the device body.
The socket metal fitting can be smoothly elastically deformed when the reflective shade is attached.
