摘要： 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.

A light emitting package according to an embodiment of the present invention may include a body, a light emitting diode chip, and a light transmission member. The body includes a cavity open at an tipper side thereof and may be formed of a ceramic material. The light emitting diode chip is mounted in the cavity of the body and may generate and emit UV light. The light transmission member may be disposed on top of the body to cover the cavity. In addition, the light transmission member may include a light transmission layer formed of sapphire and a light loss prevention layer formed on at least one surface of the light transmission layer. The light loss prevention layer may include a lower light loss prevention layer formed on a lower surface of the light transmission layer. The light emitting diode chip and the light transmission member may be spaced apart from each other to form a space therebetween. UV light emitted from the light emitting diode chip may sequentially pass through an air layer, the lower light loss prevention layer, and a sapphire layer so as to be emitted from the light emitting package.
