Light and air filtration unit with ozone catalytic oxidation

A light and air filtration unit with ozone catalytic oxidation, the unit comprising:

• a main housing comprising an upper tubular portion and a lower tubular portion connected to a lower side of the upper tubular portion, the lower tubular portion being formed therearound with a plurality of main housing air vents;
• a hollow cylindrical catalytic filter disposed around the main housing air vents;
• a hollow cylindrical high efficiency particulate air (HEPA) filter disposed around the hollow cylindrical catalytic filter;
• at least one ozone generator disposed on an outer side of the HEPA filter;
• an electric fan mounted within the upper tubular portion;
• a light source provided on a lower side of the main housing;
• a main control unit mounted within the lower tubular portion, the main control unit being electrically connected to the at least one ozone generator, the fan and the light source;
• a lamp shade defining an outer casing, the outer casing comprising a top wall disposed above the upper tubular portion and formed with a plurality of air exhaust holes, a side wall surrounding and spaced apart from the HEPA filter and the light source, and a bottom opening;
• and
• an annular air channel formed between the side wall of the outer casing and the HEPA filter;
• wherein the fan draws air into the unit through the bottom opening and out of the unit through the air exhaust holes.
