Abstract
In an air-outlet unit that forms an air outlet of an air conditioner in an automobile, a light-emission control unit controls, in accordance with the airflow rate of the air conditioner that is obtained from an air-conditioning control device of the automobile, an LED driving unit that drives an LED array in such a manner that the amount of light that is emitted from the LED array and that activates a photocatalytic filter increases as the airflow rate of the air conditioner increases. The light that is emitted from the LED array is visible light, and some of the light that is reflected by the photocatalytic filter transmits to an area outside of the air-outlet unit by passing through fins that adjust the direction and the flow rate of the air blown by the air-outlet unit.
