[Industrial applications]

 The present invention relates to a direct-mounted lighting fixture, and more particularly to a direct-mounted lighting fixture integrally provided with a return air suction port for air conditioning.

[0002]

[Prior art]

 In buildings such as modern buildings, in order to maintain the indoor environment such as temperature and humidity, the air outlet that blows out temperature and humidity controlled air to the ceiling inside the air-conditioned room and the return air intake that exhausts indoor air A mouth is provided for air conditioning.

In general, when air conditioning is performed, an anemo type or a pan type air outlet and a line diffuser are provided as air outlets. On the other hand, as the return air suction port, as shown in FIG. 7, a return air hole 2 is provided at a required portion of the mounting surface 1 such as a ceiling, and the return grill 3 is attached to the return air hole 2. well known.

In this way, since the return grill 3 and the lighting fixture 4 are individually mounted on the mounting surface 1 in the air-conditioned room, it requires a lot of man-hours for the mounting work and may damage the appearance of the air-conditioned room. There was a problem.

Further, in the direct-mounted lighting fixture as shown in FIG. 7, as shown in FIG. 8, the hanging bolt 5 such as a stud bolt installed in a building is attached to the lighting fixture body 6 of the lighting fixture 4. It is inserted into the provided mounting hole 7, and a nut is screwed onto the tip of the hanging bolt 5 inside the lighting fixture body 6 and fixed to the mounting surface 1. In this case, since the position of the mounting hole 7 of the lighting fixture body 6 is fixed, it takes a lot of man-hours to position the hanging bolt 5 when it is planted in a building.

【Example】

 1 to 3 show an embodiment of a direct lighting fixture according to the present invention. This direct-mounted luminaire 11 is a lamp-exposed type, and the luminaire main body 12 has a substantially rectangular parallelepiped shape and accommodates electric parts such as a lighting device (not shown) therein. The lamp socket 13 is attached via the socket base 14. The lamp sockets 13 are paired and opposed to each other in the longitudinal direction of the luminaire main body 12, and the straight tube fluorescent lamps 15 are attached to the lamp sockets 13 so that the lamp sockets 13 can be lighted and are electrically connected to electric parts such as a lighting device.

On the lower surface of the luminaire main body 12, a reflecting plate 16 having a so-called inverted Fuji cross-section and painted in white is attached. The reflector 16 is slightly larger than the luminaire main body 12 and has an upper surface opening, and is attached so as to cover the luminaire main body 12. Two rectangular socket insertion holes 17 are provided in the vicinity of both ends of the reflection plate 16, and when the reflection plate 16 is attached to the main body 12 of the lighting fixture, the lamp socket 13 projects below the reflection plate 16 and a straight tube fluorescent lamp. 15 can be attached.

The lighting fixture main body 12 is provided with three long holes on both side surfaces along the length thereof, and these long holes are used as a return air suction port 18 for sucking return air for air conditioning. . Further, the back surface of the luminaire main body 12 has an inner flange portion 19 formed in the vicinity of the outer periphery thereof, and a rectangular opening 20 is provided. The opening 20 is connected to the return air suction port 18 so that air can flow in the lighting fixture body 12, and when the lighting fixture body 12 is attached to the attachment surface 21, the attachment surface is attached. When the return air hole 22 provided in 21 is covered with the luminaire main body 12, the air in the air-conditioned room that is in communication with the return air hole 22 and sucked in through the return air suction port 18 can be exhausted.

The luminaire main body 12 is provided with two rectangular plate-shaped supporting members 23, which are movable within the opening 20. The support tool 23 has a circular bolt insertion hole 24 in the substantial center thereof. Then, the vicinity of the lower end of a suspension bolt 25 as an attachment tool implanted in the building is inserted into the bolt insertion hole 24 and screwed into a nut, and the support tool 23 is engaged with the suspension bolt 25. The support 23 is attached to the luminaire main body 12 so as to be movable and not to be separated from the luminaire main body 12. The support 23 may be attachable to and detachable from the luminaire main body 12 as necessary.

This direct-mounted luminaire 11 is such that when the luminaire main body 12 is mounted on the mounting surface 21, the return air hole 22 provided on the mounting surface 21 is covered by the luminaire main body 12 and mounted. The return air suction port 18 communicates with the return air hole 22 through the opening 20 on the rear surface of the appliance body 12, and the air in the air-conditioned room can be sucked from the return air suction port 18 to exhaust the air in the air-conditioned room. Also, by using this direct-mounted luminaire 11, it is possible to mount the luminaire and the return air suction port at the same time, reducing the number of mounting steps and improving the appearance of the mounting surface in the air-conditioned room. To do. Further, when mounting the direct-mounted lighting fixture, it is possible to easily mount the mounting fixture by moving the supporting fixture without positioning the mounting fixture so strictly, and the number of steps can be reduced.

4 and 5 show another embodiment of the present invention. This direct-mounted luminaire 31 is different from the previous embodiment in that a globe 32 for covering a straight tube fluorescent lamp is provided, but the structure of the luminaire main body 33 is basically substantially the same as the previous embodiment. . Further, three long-hole-shaped return air suction ports 34 are provided on both side surfaces along the length of the lighting device main body 33, and the air in the air-conditioned room is sucked in from the return air suction ports 34 to illuminate. The air in the air-conditioned room is exhausted from the return air hole 36 provided in the mounting surface 35 through the opening on the rear surface of the appliance body 33.

FIG. 6 shows another embodiment of the present invention. The direct-mounted luminaire 41 is a holder-type luminaire with a shade, and is located at a position covered by the straight-tube fluorescent lamp 43 above the straight-tube fluorescent lamp 43 mounted in the lamp socket 42. Is provided with a return air suction port 45. Then, the air in the air-conditioned room sucked from the return air suction port 45 passes through the opening 46 on the rear surface of the lighting fixture body 44 and is exhausted from the return air hole 48 provided on the mounting surface 47.
