Abstract:
1. An air purification apparatus, comprising: a plurality of plate substrates each having an inner surface and an outer surface, wherein said inner and outer surfaces are coated with a photocatalyst and wherein said plurality of plate substrates possess a relatively high transmittance with respect to a wavelength range for activating said photocatalyst wherein a total number of said plurality of plate substrates is dependent on said transmittance; an adjustable interval between each of said plurality adjacent plate substrates; a light source surrounded by said plurality of plate substrates and located in a direction parallel to a direction of air flow, wherein said plurality of plate substrates absorbs a light energy with a wavelength shorter than a cut-off activation wavelength to activate said photocatalyst and thereby improve a usage efficiency of said light energy and an air purification efficiency for purification of air by said apparatus; a fixture associated with a plurality of fixture buckle for mounting said plurality of plate substrates and said light source; and a channel formed from and located at a base of said fixture providing an electrical circuit connection to said light source.
