BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a square luminaire directly mounted on a ceiling.

[0002]

2. Description of the Related Art Conventionally, there is no need to adjust the direction after mounting a round luminaire because it has no direction even if it is mounted on a ceiling. There is a sense of incongruity if not installed in parallel. For this reason,
After the square luminaire was directly mounted on the ceiling, the mounting screws were loosened or removed and re-installed to adjust the direction.

[0003]

As described above, the directivity adjustment is troublesome when the square lighting fixture is directly mounted on the ceiling as described above, and the directivity adjustment can be easily performed on the square lighting fixture directly mounted. At present, it is desired to be able to do so. In the case of lighting fixtures directly attached to the ceiling, if a large external force is applied during cleaning or the like, the external force cannot be absorbed, and the external force concentrates on the screw for fixing the lighting fixture to the ceiling. There was a problem that the wearing strength was weakened.

[0004] A pendant-type lighting fixture conventionally suspended from a ceiling with a wire rod has a wooden reflector mounted on the lamp body. In this case, since a wooden reflector is suspended from the wire rod, a wooden reflector is hung by an external force. The wire part can be absorbed by bending, and the edge of the central hole of the wooden reflector is placed on the upper periphery of the lamp body, so that the wooden reflector is rotated around the lamp body. Is possible, but
In this device, even if the direction of the wooden reflector is determined, the direction is changed by twisting or shaking because the wire is hung by the wire, and the wooden reflector is simply placed on the lamp body. The mounting of the wooden reflector is unstable, and the direction is easily changed by rattling in the vertical direction.In other words, it is not used in this kind of pendant type lighting equipment. There is a problem that the direction changes naturally while you are there.

The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to easily adjust the directionality of a rectangular lighting fixture directly mounted on a ceiling.
Moreover, it is an object of the present invention to provide a lighting fixture that can stably mount a rectangular reflector and can absorb an external force when it is directly mounted on a ceiling even when it is applied.

[0006]

A lighting device according to the present invention includes a lamp body 2 mounted directly on a ceiling 1 and a rotatable lamp body 2 which is rotatable around the lamp body 2 and which moves up and down with respect to the lamp body 2. And a rectangular reflecting plate 3 attached so as not to be attached. By adopting such a configuration, the above-described problem of the conventional example has been solved and the object of the present invention has been achieved. is there.

[0007]

A lamp body 2 mounted directly on a ceiling 1 and a rectangular reflector 3 rotatable around the lamp body 2 and mounted so as not to move up and down with respect to the lamp body 2. With this configuration, the direction can be easily adjusted by rotating the rectangular reflecting plate 3 with respect to the lamp main body 2 after directly attaching to the ceiling 1. And although the rectangular reflector 3 is rotatably attached to the lamp body 2 so that the direction can be adjusted, the lamp body 2 in which the square reflector 3 is directly attached to the ceiling 1 is provided. By mounting so that it does not move up and down, the rectangular reflector 3 can be securely mounted, and the possibility that the direction naturally changes after the direction is adjusted is eliminated. Further, when an external force exceeding a certain level acts, the reflecting plate 3 rotates with respect to the lamp body 2 to absorb the external force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the accompanying drawings. The lamp body 2 is directly mounted on the ceiling 1. In order to directly attach the lamp body 2 to the ceiling 1, for example, there are cases where the lamp body is fixed to the ceiling with screws, and cases where the lamp body 2 is fixed to the ceiling using a hooking ceiling. In the embodiment shown in the accompanying drawings, an embodiment in which the ceiling is directly attached to a ceiling using a hooking ceiling is shown.

As shown in FIG. 5, the lamp body 2 is provided with a center hole 5 in a body plate 2a. A holder 6 is fitted and fixed in the center hole 5, and an inverter block 7 is provided on the lower surface of the body plate 2a. The lamp holder 8 is attached, and the main body cover 9 is screwed to the lower surface of the main body plate 2a.
To cover the inverter block 7 and to protrude the lamp holder 8 from the hole 10 of the main body cover 9. The lamp 24 is detachably attached to the lamp holding spring 27 and the lamp holder 8 attached to the main body cover 9.

A hole 17 is formed in the holder 6 attached to the main body plate 2a, and an adapter 18 having a hooking sealing plug 19 is removably fitted into and attached to the hole 17. The above-mentioned adapter 18 is provided with the hooking sealing plug 1 on the upper surface.
Reference numeral 9 denotes a hook-and-ceiling rosette 4 fixed to the ceiling 1 and fixed. Here, the configuration in which the hooking sealing plug 19 is hooked and fixed to the hooking sealing rosette 4 can adopt a conventionally well-known configuration as it is, and therefore, the disclosure of the specific configuration is omitted. Then, when the hole 17 of the holder 6 is fitted from below onto the adapter 18 hooked and fixed to the hooking sealing rosette 4 fixed to the ceiling 1 with the hooking sealing plug 19, the inner surface of the hole 17 Of the adapter 18 is detachably locked to a locked portion 21 provided on the outer surface of the adapter 18, and a power supply unit (not shown) of the adapter 18 and a power receiving unit (not shown) of the holder 6.
And are electrically connected. Here, although the specific structure of the detachable locking means for detachably forming the locking portion 20 and the locked portion 21 is omitted, any conventionally known removable locking means can be adopted. is there.

As shown in FIG. 2, an outer peripheral portion of the main body cover 9 is an annular concave groove 11 having a U-shaped cross section, and is provided between the annular concave groove 11 and an outer end of the main body plate 2a. The fitted part 15 is constituted. Further, a support piece 12 extends outward from an upper edge of an outer end of the annular groove portion 11. The reflector 3 having a rectangular outer shape is disposed on the outer periphery of the lamp body 2 to which the body cover 9 is attached as described above. A circular hole is provided at the center of the rectangular reflecting plate 3, and a fitting edge 14 as shown in FIG. 2 is formed at the edge of the circular hole. The fitting edge 14 is a fitting part 15 of the lamp body 2.
The rectangular reflector 3 is rotatably attached to the lamp body 2. Here, a plurality of upper and lower point-like pressure contact portions 16 provided near the fitting edge portion 14 are in pressure contact with the bottom of the concave groove portion 11 and the lower surface of the main body plate 2a, and apply an appropriate frictional force to vertically move. It is not reflected until it is rotated with a relatively strong force (that is, when a certain force or more is applied with the intention of rotating the reflector 3 with respect to the lamp body 2). When the plate 3 rotates and other small force (for example, a switch operation force or other small external force) acts, the reflection plate 3 is prevented from rotating with respect to the lamp body 2 carelessly. . Further, when an external force of a certain level or more is applied, it rotates to absorb a shock.

A shade 25 having a square outer shape is detachably attached to the reflector 3 having a square outer shape. The shade 25 can be attached to the reflection plate 3 by a conventionally known attachment means. The rectangular lighting fixture directly attached to the ceiling 1 having the above-described configuration is attached as described below.

That is, after the adapter 18 is attached to the hanging ceiling rosette 4 previously attached to the ceiling 1, the lamp body 2 with the rectangular reflector 3 attached to the outer periphery is mounted with the packing 26 on the upper surface of the lamp body 2. By pushing up in this state and fitting the hole 17 of the holder 6 to the adapter 18, the locking portion 20 is detachably locked to the locked portion 21 as described above, and the power feeding portion and the power receiving portion are connected. The lighting fixture is directly attached to the ceiling 1 as shown in FIG. In this case, the lamp 24 may be attached to the lamp holder 8 in advance, or the shade 25 may be attached to the reflector 3 in advance. Further, the lamp body 2 to which the reflector 3 is attached may be pushed up and attached as described above, and then the lamp 24 and the shade 25 may be attached.

The rectangular lighting fixture is mounted as described above, but before the lamp 24 or the shade 25 is mounted, or after the lamp 24 or the shade 25 is mounted, as shown in FIG. 3 is rotated with respect to the lamp body 2 by holding the hand 3 to adjust the mounting direction. In other words, the atmosphere of the room is adjusted by adjusting it so that it is parallel to the wall of the room, or by rotating it to a desired position such as when the shade 25 has a pattern. In particular, in the case where the adapter is directly attached to the ceiling using a hooking ceiling as in the embodiment and fixed, the orientation of the adapter 18 is determined by the fixing position of the hooking sealing rosette 4,
The direction of the holder 6 is determined by the direction of the adapter 18, which determines the direction of the lighting fixture. In the present invention, the direction of the reflector 3 with respect to the lamp body 2 is easily changed, so that the direction is adjusted. Can be easily performed.

[0015]

According to the present invention, the lamp body is directly mounted on the ceiling as described above, and the lamp body is rotatable around the lamp body and does not move vertically with respect to the lamp body. It is easy to adjust the directionality of the square lighting fixture directly mounted on the ceiling because it is equipped with a rectangular reflector that can be directly mounted on the ceiling. The mounting of the board is stable, and even if it is directly mounted on the ceiling, if the external force exceeds a certain level, the reflector can rotate to absorb the external force. It can prevent breakage.
