Photocatalyst-based Air Cleaning Module for Attaching and Detaching to Station type Electric Lamp Equipped with Downward Light Emitting Tube type Light Source
The present invention relates to a photocatalyst-based air cleaning module capable of being attached to or detached from a stationary electric lamp equipped with a top-down optical tube-shaped light source, wherein the stationary electric lamp comprises: a light source unit for emitting light having a designated wavelength (or wavelength band) by using power and having a structure including a cylindrical optical tube； a socket unit for inserting the light source unit from the bottom, supporting the same, and supplying power to the light source unit； a lampshade unit for inducing the light, emitted through the light source unit inserted into the socket unit, to diffuse into a designated range, and of which the upper area is closed； and a frame unit coupled to at least one between the socket unit and the lampshade unit, having a structure installed in the surface of a desk or the floor surface. In addition, the air cleaning module includes: an attachment structure unit having a designated attachment area with a geometric structure, capable of being attached to a designated optical tube area of the optical tube-shaped light source unit inserted into the socket unit from the bottom, and for maintaining an attachment state to the designated optical tube area of the optical tube-shaped light source unit by structural features of the attachment area and friction force； a photocatalyst material unit formed by coating a designated photocatalyst material on a designated air contact area from the area of the attachment structure unit, or formed by coating a designated photocatalyst material on a designated air contact area from the area of a contact structure unit installed to be in contact with air in at least one side area of the attachment structure unit； a generation unit placed or coupled to one side of the attachment structure unit, attached to a designated optical tube area of the light source unit, in order to receive the light radiated from the light source unit and g
