The two switches are connected in series, and when either one of the switches is turned off, both the illumination lamp 18 and the fan motor 30 are turned off. Is stopped. In FIG. 8, a power source for the illumination lamp 18 and a power source for the dust collector are separately provided. However, by using an inverter device as shown in FIG. 9, both power sources can be shared.

Next, the configuration near the dust collector will be described with reference to FIGS. As shown in FIG. 5, when the maintenance cover 40 is removed from the second umbrella 12, the filter 42 and the dust collecting electrode plate 44 can be removed from the wind tunnel 20. As the filter 42, a filter generally used for an air purifier or an air conditioner or a filter using activated carbon or a titanium oxide nonwoven fabric is used. The collecting electrode plate 44 is a charged electrode plate described below.
It is formed of a donut-shaped metal plate having a round circular hole 442 opposed to the fourteen electrodes 142. FIG. 6 shows the charging electrode plate 14, and FIG. 7 is a sectional view of the section taken along line AA of FIG. That is, the charging electrode plate 14 is
As shown in FIG. 6, needle-shaped electrodes 142 to 142 are provided in a donut-shaped metal plate similar to that described above, and these electrodes 142 are provided so as to face the holes 442 of the dust collecting electrode plate 44 as described above.

In the second embodiment, a dirt detection lamp 50 and a dust collector switch 52 are provided in addition to the above configuration. The dirt detection lamp 50 is provided near the mounting portion of the illumination lamp 18 and at a position where the dirt detection lamp 50 can be easily identified from below the lighting fixture 10. The dirt detection lamp 50 is for displaying the detection result of a dirt detection sensor (not shown). When the dirt sensor detects dirt due to a change in the degree of light transmission or an increase in current at the dust collection electrode, the illuminating light 18 is turned on. This is to display light of a color arrangement different from the above color. Further, the dust collector switch 52 is provided on the case 101 on the upper surface of the lighting fixture 10, and is provided in a portion where it is difficult to perform an erroneous on / off operation. As described above, in the second embodiment, an air cleaner is formed by using the fan motor 30, the fan 32, the filter 42, the dust collecting electrode plate 44, and the charging electrode plate 14 as main components.

FIG. 10 shows a third embodiment of the present invention. In FIG. 10, the shape of the lighting fixture 10 used in the first or second embodiment is different. That is, in the third embodiment, the lighting fixture shown in FIG. 1 or FIG. 4 has the second illuminating lamp 19 outside the second umbrella 12, and the outer shape is formed of an acrylic cover also serving as a reflector. Except for the above, the configuration is the same as or equivalent to the configuration of the lighting fixture of the first embodiment or the second embodiment, and therefore the description is omitted.

FIG. 11 shows a fourth embodiment of the present invention. In the fourth embodiment, there is shown a lighting apparatus which does not have an umbrella as in the first to third embodiments and is formed only of a donut type fluorescent lamp. In such a lighting device, unlike the configuration shown in each of the above-described embodiments, a filter and a dust collector portion are arranged in the inner diameter of the fluorescent lamp,
Forced convection is generated by the fan 32.

In each of the above embodiments, the fan 32 is arranged above the fan motor 30 as a sirocco type fan. However, a fan structure other than this, such as a screw type, is arranged above the fan motor 30. You may. The lighting device 20 is not limited to the ceiling hanging type, and may be directly attached to the ceiling.

The operation of the illumination lamp 18 and the dust collector may be performed by remote control using a remote controller instead of using a switch attached to the apparatus. In such cases lighting fixtures
It is not necessary to add a switch to 10.

In addition, by detecting at least one of a smoke sensor and an odor sensor in addition to the dirt detection sensor, fine air control can be performed. Also filter 42
The positions of the dust collecting electrode plate 44 and the charging electrode plate 14 can be arbitrarily selected as long as they are in the wind tunnel 20, and the size and position of the umbrella can be appropriately changed according to the required air cleaning performance required by the design.

The filter 42, umbrellas 11, 12 and case 101
May be filled with a photoregenerating catalyst such as titanium oxide which has excellent antibacterial and deodorizing effects, and the same effect can be obtained with an air cleaner using an electrostatic dust collector using ions. However, the present invention is not limited.

Next, the operation of the present invention will be described. According to the first embodiment, convection occurs from the table side toward the ceiling by the fan 32 attached to the lighting fixture 10. As a result, the smell of food or cigarettes placed on the table is sucked up by the fan 32, but a deodorant such as activated carbon is used as a filter 42 near the entrance of the wind tunnel 20 where the main convection of the lighting device 10 occurs. Since it is provided, the air reaching the fan 32 is deodorized.

Further, in the second to fourth embodiments, since the electric dust collecting electrode plate 44 and the charging electrode plate 14 are provided as the dust collector, a more excellent air cleaning effect can be obtained. Also, by installing a dirt sensor such as the dirt detection lamp 50,
The dust collector is operated only when the air is dirty.

[0024]

According to the above configuration, as shown in FIG.
The odor of food and cigarettes is sucked up toward the ceiling and passed through a filter or a dust collector to obtain an air purifying action, thereby eliminating indoor odors. FIG. 12 shows a convection state in a room when the lighting fixture of the present invention is used.

According to the present invention, since a dust collector and the like are provided in the lighting fixture, a separate air purifier is not required, and a useless space in the room can be omitted. In addition, since the dust collector portion can be raised near the ceiling, it is easy to collect dust particularly in warm air, and an excellent air cleaning effect can be obtained as compared with a floor-mounted or wall-mounted air cleaner.

Further, there is a secondary effect of realizing a comfortable air-conditioned space by convection of room air.
