An exemplary self-cleaning light source module includes a light source assembly, a housing, and a photocatalyst layer. The light source assembly includes a first light emitting component for emitting visible light and a second light emitting component for emitting UV light. The housing encloses the light source assembly therein and has a light permeable portion. The photocatalyst layer is formed on an outer surface of the light permeable portion of the housing.
