The present invention relates to a photocatalyst sterilization module for air purification having the functions of condensing and diffusing ultraviolet rays, comprising: a photocatalyst air filter which comprises a medium filter or a HEPA filter, is arranged on the rear side of a pre-filter installed in an air cleaner, and which filters fine dust in the air having passed through the pre-filter, and of which the surface is coated with a photocatalytic agent so as to decompose contaminants and bacteria through a catalytic reaction by light; a plurality of ultraviolet lamps which are installed between the photocatalyst air filter and the pre-filter and which emit ultraviolet rays and sterilize the air having passed through the pre-filter and induce a catalytic reaction in the photocatalyst air filter; and an ultraviolet condenser and diffuser which accommodates the ultraviolet lamps so as to be seen therethrough, and which provides the ultraviolet rays emitted from the ultraviolet lamps to the pre-filter in a condensed state and provides the ultraviolet rays to the photocatalyst air filter in a diffused state. |
