Abstract
An air purification module for purifying air includes a photocatalyst filter and a light source unit sequentially arranged in a selected direction. The light source unit is spaced apart from the photocatalyst filter to provide light to the photocatalyst filter and includes a substrate and a light source disposed on the substrate. The substrate includes at least one aperture to control a flow channel and a flow velocity of air so as to improve air purification effects through the photocatalyst filter when the air flows from the substrate towards the photocatalyst filter.
