A rectangular vertical plate portion 12 that is rotatable about the center and is slidably in contact with the inner peripheral surface thereof, and is attached to the upper end of the rectangular vertical plate portion 12 and slidably contacts the inner peripheral surface of the air conditioning air passage 9. It consists of a possible semi-circular horizontal plate part 13. Then, the rectangular vertical plate portion 12 of the air passage switching member 11 is connected to the upper end portion of the operation rod 14 which is inserted through the centers of the heat recovery box 5 and the lamp shell 2 and protrudes downward of the lighting fixture 1. By rotating the operating rod 14 by 180 ° around the axis, the opening / closing (switching) operation of the air passage switching member 11 is performed. On the other hand, on the upper surface of the horizontal wind passage 7, as shown in FIGS. 1, 5 and 6,
A semi-circular exhaust slit 15 centering on the center of the air conditioning air passage 9 is provided, and at the symmetrical position of the exhaust slit 15 centering on the air conditioning air passage 9 on the upper surface of the heat recovery box 5, An exhaust slit 16 having a similar semicircular arc shape is provided.

In the air-conditioning luminaire having the above-mentioned structure, during heating, when the air passage switching member 11 is rotated by the operating rod 14 to set the notch 10 in the heating mode as shown in FIG. The exhaust slit 15 of the road 7 is opened, and the exhaust slit 16 of the heat recovery box 5 is closed. The supply air SA for heating from the air conditioner passes through the air conditioning air passage 9 and the heat recovery box 5
At this point, the heat generated by the lighting fixture 1 is recovered and supplied to the room through the vertical air passage 6. On the other hand, the return air R from the room
A reaches the horizontal wind passage 7 from the vertical wind passage 8 of the horizontal wind passage 7,
Air is returned from the exhaust slit 15 to the ceiling. or,
When cooling, the air duct switching member 11 is pivotally operated by the operating rod 14 to open the cutout portion 10 as shown in FIG. 6, and the exhaust slit 15 of the horizontal air duct 7 is set.
Is closed and the slit 16 of the heat recovery box 5 is opened. Air supply air SA for cooling from the air conditioner reaches the horizontal air passage 7 through the air conditioning air passage 9 and is supplied indoors from the vertical air passage 8.
On the other hand, the return air RA from the room reaches the heat recovery box 5 from the vertical air passage 7 of the heat recovery box 5, where the heat generated by the lighting fixture 1 is recovered and returned to the ceiling above the exhaust slit 16. It Therefore, in the above air conditioning lighting equipment, during heating and cooling, the air conditioning air collects the heat generated by the lighting equipment in the heat recovery box and supplies it to the room and discharges it outside the room, reducing the air conditioning load during cooling and heating. can do.

Here, the reduction of the air-conditioning load will be described for the lighting fixture having eight 40 W fluorescent lamps.
The heating value of lighting is 0.86, which is the conversion factor from power to heat.
Assuming that the safety device is 1.25, it becomes 40W × 8 × 0.86 × 1.25 = 344Kcal / h, and the amount of heat that escapes to the back of the ceiling is 60 of the amount of heat generated by lighting.
Since it is%, it becomes 344 × 0.6 = 206.4 Kcal / h, and 206.4 Kcal per appliance during heating.
/ H reduces the heating load. However, in the case of an ordinary lighting device, in reality, the heat that once escaped to the ceiling is gradually released into the room with a time delay, so the amount must be subtracted from the above value. Since the amount is about 60% of the amount that escapes to the ceiling, the load reducing effect of this lighting fixture is 206.4 × 0.4 = 82.56 Kcal / h, which is considered to be about 80 Kcal / h. Further, during cooling, since it is generally about 40% of the heating value of illumination, 344 × 0.4 = 137.6 Kcal / h, which is about 140 Kcal / h per appliance, which reduces the cooling load.

[0010]

As described above, according to the first air conditioner lighting device of the present invention, the air conditioner air is used as the lighting device in the heat recovery box during heating and cooling in accordance with the opening / closing operation of the air passage switching member. Since the generated heat is collected, supplied to the room and discharged to the outside of the room, the air conditioning load at the time of cooling and heating can be reduced.
Further, according to the second lighting fixture, in addition to the function and effect of the first lighting fixture, since the opening / closing operation of the air passage switching member can be performed below the lighting fixture, switching between cooling and heating can be easily performed. it can.
