Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting fixture such as a ceiling-embedded type.

[0002]

2. Description of the Related Art In a ceiling-embedded luminaire, a lamp socket for connecting a lamp, a lighting device including a ballast, a terminal block, a reflector and the like are separately attached to a main body of the luminaire.

[0003]

By the way, at the time of construction for mounting a lighting fixture on the ceiling, if there is a mounting opening on the upper surface of the fixture main body, the fixture main body is attached to the ceiling structure through the mounting opening. Not only can it be easily installed, but wiring processing such as pulling in of the power supply line can be facilitated and workability is improved.

However, in the structure of the conventional luminaire, when the mounting opening is provided on the upper surface of the luminaire main body, another chassis is provided for mounting the lighting device or the lighting device or the like is provided on the side of the luminaire main body. To attach the device, increase the height of the device body and increase the size.

Therefore, conventionally, it has been difficult to achieve both improvement in workability and reduction in thickness.

The present invention has been made in view of the above points, and by integrally forming each component to be attached to the instrument body, it is possible to improve workability and prevent an increase in size. It is an object of the present invention to provide a lighting fixture that can ensure versatility.

[0007]

According to the present invention, a substantially box-shaped instrument body having an irradiation opening on the lower surface and an attachment opening on the upper surface, and at least a lamp socket and a lighting device for lighting the lamp are integrated. And a reflection plate mounted on the instrument main body, and the reflection plate is attached in a state in which the attachment opening of the instrument body is closed.

[0008]

In the present invention, at least the lamp socket and the lighting device are integrally mounted on the reflecting plate to form a unit, which is mounted on the main body of the fixture. This unitization makes it possible to provide a mounting opening on the upper surface of the instrument body to improve workability and prevent the instrument body from increasing in size in that case. Moreover, the unitization makes it possible to ensure versatility.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a sectional view of a ceiling-embedded luminaire, and FIG. 2 shows a plan view thereof. Reference numeral 1 denotes an instrument body, which is formed in the shape of a rectangular box having an irradiation opening 5 on the lower surface from the upper plate 2 and the side plate 3. A relatively large quadrangular mounting opening 6 is formed in the upper plate portion 2, and a plurality of mounting holes 7 are formed at the edge of the mounting opening 6. An edge portion 8 joined to the ceiling surface is formed on the lower edge of the side plate portion 3.

Reference numeral 11 denotes a reflecting plate, the lower surface of which is a reflecting surface 12, and a plurality of single-ended die lamps 13 arranged to face the reflecting surface 12 are bent downward in a substantially C-shape. A lamp housing recess 14 is formed. A lamp socket 15 for connecting a single-ended die lamp 13 is integrally attached to one end of a reflecting surface 12 forming each lamp housing recess 14.

A lamp housing recess adjacent to the upper surface of the reflector plate 11.
In the lighting unit accommodating concave portion 16 formed between 14, a plurality of lighting devices 17, such as an inverter lighting device, and a terminal block 18 are provided.
Are integrally attached. The plurality of lamp sockets 15 and the corresponding lighting device 17 are connected by wiring, and each lighting device 17 and the terminal block 18 are connected by wiring.

Therefore, the plurality of lamp sockets 15, the plurality of lighting devices 17, and the terminal block 18 are integrally attached to the reflector 11 to form a unit body 19. The lighting device 17 and the terminal block 18 are the lighting unit housing recesses.
The depth is smaller than 16 and the lighting unit housing recess 16
It does not protrude from the instrument body 1 even if it is attached to.

A louver 21 is arranged in the irradiation opening 5 of the instrument body 1.

Next, the operation of this embodiment will be described.

At the time of construction, the instrument body 1 is embedded and fixed in a mounting opening formed on the ceiling surface. At this time, the instrument body 1 can be easily attached to the ceiling structure through the attachment opening 6 of the instrument body 1, and wiring processing such as lead-in of the power supply line can be facilitated, and the workability is good.

Then, the power line drawn from the mounting opening 6 is connected to the terminal block 18 of the unit body 19, the unit body 19 is inserted into the instrument body 1, and the mounting screw 31 is passed through the reflection plate 11 to the instrument body. It is fixed to the mounting hole 7 of No. 1 by screwing.

Further, the lamp 13 is connected to the lamp socket 15, and the louver 21 is attached to the irradiation opening 5 of the instrument body 1.

Therefore, since the plurality of lamp sockets 15, the plurality of lighting devices 17 and the terminal block 18 are integrally attached to the reflector 11 to form a unit, the fixture body 1
It is possible to improve the workability by providing the mounting opening 6 in the, and it is possible to prevent the instrument body 1 from increasing in size.

Further, since the thickness of the lighting device 17 and the terminal block 18 is thinner than the depth of the lighting unit accommodating recess 16, even when the unit body 19 is attached to the fixture body 1, it does not protrude from the upper surface of the fixture body 1. ..

Further, by mounting the lamp socket 15, the lighting device 17 and the terminal block 18 on the reflector plate 11 to form a unit, the unit body 19 can be commonly used for various kinds of appliances and the versatility can be ensured.

[0022]

According to the present invention, at least the lamp socket and the lighting device are integrally mounted on the reflection plate to form a unit, which can be attached to the main body of the fixture. This unitization makes it possible to improve the workability by providing a mounting opening on the upper surface of the instrument body.
In that case, it is possible to prevent the device body from increasing in size. Moreover, versatility can be ensured.
