FIGS. 1 to 3 show a lighting device 1 according to an embodiment of the present invention. The lighting device 1 is provided with an air-conditioning outlet 4 formed in a rectangular cylindrical shape between lighting boxes 2 and 3 as a whole. It is formed integrally.

That is, the lighting boxes 2 and 3 are symmetrical to each other, both have an upper surface plate and a peripheral side plate, and the opening 5
a fluorescent plate 7a as a light source 7 and its mounting base 7b are installed on the horizontal plate upper surface 6a, and the opening of the light source 7 is provided. A shielding plate 8 is erected at the end of the horizontal plate portion 6 on the 5a side, and further from the lower end of the side plate of the lighting cover body facing the horizontal plate portion 6 through the opening portion 5a, above the opening portion 5a and above the light source portion 7. The lower end 9a and the upper end 9b of the reflector 9 are fixed to the inner wall surface of the illumination cover body 5 in a concavely curved shape.

The shielding plate 8 is a long plate in the longitudinal direction formed substantially at the same height as or slightly higher than the light source unit 7, and the upper edge is slightly rearward so as to reliably block direct light. It is bent to form a bent portion 8a, the base of which is a base end 8b in contact with the upper surface 6a, and the base 8b is screwed to the upper surface 6a so as to be detachably erected, or If the lower end is pivotally attached as a hinge so that the shielding plate 8 can be opened and closed forward, the maintenance such as installation and replacement of the fluorescent lamp 7a can be easily performed.

On the other hand, the air-conditioning blow-out portion 4 is formed by forming a thin steel plate into a rectangular cylindrical shape, and the upper end portion 4a is projected upward from the upper end edges of the lighting boxes 2 and 3 to form an air-conditioning duct connecting port. On the other hand, the lower end 4b is opened to the indoor side at the same height as the lower edge of the side plate of the lighting cover body 5.

The lighting boxes 2 and 3 and the air conditioning outlet 4 are joined and fixed by connecting the inner side surface plate 5a of the lighting cover 5 and both outer surfaces 4c of the air conditioning outlet 4 to the reinforcing channel 10 in the vertical direction. The L-shaped fixing bracket 11 is fixed to the upper edge of the joint by bolting or welding.

A mounting bracket 12 is fixed to an appropriate portion of the upper edge of the lighting cover body 5, and a suspension bolt 13 is fixed to the mounting bracket 12 by tightening a nut, so that the lighting apparatus 1 is suspended from the foundation ceiling. Also, a latch 14 capable of horizontally hanging the ceiling plate is protruded downward from the end of the horizontal plate portion 6 on the opening 5a side so that the ceiling plates A and B can be hooked and disposed here. It is.

With this configuration, by suspending the device 1 of the present invention on the ceiling, the lighting boxes 2 and 3 and the air-conditioning outlet 4 are installed and formed at the same time. It is only necessary to connect an air-conditioning duct to the upper end 4a of the mouth 4, and the lower ends can be hooked and supported by the ends of the ceiling plates A and B.

Next, an illumination device 20 having a configuration different from that of the illumination device 1 will be described.

As shown in FIG. 4, the illuminating device 20 includes a light source 2 on a lower surface 22b of a horizontal plate 22 formed in a rectangular plate shape.
3, a lower portion of a side cover 24 hanging down from a peripheral edge of the horizontal plate portion 22 is opened, and a translucent plate such as an acrylic plate or a lighting louver 25 is hooked at a lower end portion. The air-conditioning outlet 28 is formed on the side of the lighting box 27, which is configured so that a light-transmitting plate or a louver 25 is hooked and arranged at the opening therebetween to directly obtain light. It is configured to be juxtaposed and surrounded.

That is, a vertical plate portion 29 constituting the inner wall surface of the air-conditioning outlet 28 also serving as the side cover 24 of the lighting box 27 is fixed to the peripheral edge of the horizontal plate portion 22,
Further, a vertical plate portion 30 is disposed in parallel with the vertical plate portion 29 at an appropriate interval, and a connecting member 31 for connecting and fixing the two is disposed and fixed at an appropriate position between the vertical plate portions 29, 30. Thus, an air-conditioning outlet 28 is formed.

The upper end of the air-conditioning outlet 28 protrudes upward from the horizontal plate 22 so as to be easily connected to the joint for connecting the duct or directly to the duct, while the lower end is formed into the vertical plate 30. Is positioned slightly below the lower end of the vertical plate portion 29, that is, the lower end of the side cover 24, and the translucent plate or louver 25 is positioned above the lower end edge of the vertical plate portion 30. .

The suspension bolt 32 is fixed to the upper surface 22a of the horizontal plate 22 by the bolt, whereby the lighting device 20 is suspended from the base ceiling. Further, a locking portion 33 capable of locking a horizontal plate is fixed to the outside of the lower edge portion 26a of the vertical plate portion 26, and the ceiling plates A and B are locked here, and both sides are combined with the ceiling plate. Let me do it.

In this way, the light beam can directly illuminate the light from the translucent plate or the louver 25 and, at the same time, air-condition the room through the air-conditioning outlet 28.

[0024]

As described above, if the lighting device is formed by integrally forming the lighting box and the air conditioning outlet, the manufacturing cost can be reduced as one device, and the lighting device can be suspended from the base ceiling. The air-conditioning duct only needs to be connected to the upper end of the air outlet, so that the work of mounting the ceiling can be performed easily and efficiently, and the system can be designed, produced, and constructed systematically. Further, by integrally forming the outlet and the lighting device portion, it is possible to bring uniformity and width to the overall design.

Further, if the shielding plate is installed upright so as to be detachable or openable and closable, maintenance such as installation and replacement of the light source unit can be easily performed.
