PHOTOCATALYST-BASED AIR CLEANING MODULE CAPABLE OF BEING ATTACHED TO OR DETACHED FROM STATIONARY ELECTRIC LAMP EQUIPPED WITH BOTTOM-UP BULB-SHAPED 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 bottom-up bulb-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 bulb-shaped external appearances； a socket unit for inserting the light source unit from the top, 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, and 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 bulb area of the bulb-shaped light source unit inserted into the socket unit from the top, and for maintaining an attachment state to the designated bulb area of the bulb-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 bulb area of the light source unit, in order to receive the light radiated from the light source unit and generate designated power； and a fan unit operating based on the p
