In addition, indoor air is circulated through the lighting fixture 1 by the intake fan 25, dust contained in the indoor air is purified inside the lighting fixture 1, and the purified air is removed from the through hole 15 of the lighting fixture 1. While discharging into the room and discharging negative ions directly from the through hole 15 of the lighting apparatus 1 into the room, the indoor air can be effectively purified (negative ion atmosphere).

  Further, a photocatalyst may be applied to the inner surface of the lighting fixture 1. As another example, the photocatalyst 30 may be applied to the inner surface of the reflector 8. In this way, when outside air is taken into the interior of the luminaire 1, a photocatalytic effect can be given to the outside air, so that indoor air can be purified effectively. Moreover, the spear contained in tobacco smoke can be decomposed by the photocatalytic effect.

  In addition, an end cover 17 that prevents outside air from directly entering the inside of the luminaire 1 may be provided inside the reflector 8, and a photocatalyst may be applied to the surface of the end cover 17. In this way, the outside air always comes into contact with the photocatalyst adhering to the surface of the end cover 17 or the inner surface of the reflector 8 and can give a photocatalytic effect to the outside air. In particular, a photocatalytic effect can be provided. Further, since the wind speed of the intake air can be increased by the end cover 17, the outside air can be effectively taken in. Furthermore, the noise of the intake fan 25 can be reduced by providing the end cover 17.

For example, the light bulb that functions as the light emitting unit of the present application is not limited to an incandescent light bulb, and a cylindrical fluorescent lamp may be used. Further, the lighting fixture is not limited to the pendant type lighting fixture used by being hung from the ceiling, and may be a lighting fixture for hanging on a wall. Further, the intake fan may be any fan as long as it can suck outside air into the lighting apparatus. Furthermore, the number of through holes 15 for releasing negative ions to the outside may be at least one, and any number is acceptable. Moreover, in the lighting fixture 1 of the present embodiment, negative ions are generated from the left and right side bodies 9b of the container 9, but negative ions are generated from either one of the side bodies 9b. Alternatively, negative ions may be generated from all the side bodies 9b on the outer periphery of the container 9 to the outside.
