Ceiling fan airflow diffuser apparatus

A fan airflow diffuser and lighting apparatus, comprising:

• (a) a diffuser support structure configured to be mounted to a ceiling;
• and
• (b) a diffuser body coupled to the support structure, comprising:
• (i) an outer rim with an annular opening and a first light source producing visible light or UV-C light directed in an upward direction;
• (ii) a frustoconical inner ring with an angled outer wall and a diameter that is smaller than the annular opening of the outer rim, the ring positioned coaxially in relation to the outer rim, the inner ring with a central opening, the inner ring with a second light source of a light strip producing visible light directed in a downward direction;
• and
• (iii) a plurality of struts interconnecting the inner ring and the outer rim:
• (c) wherein a diameter of the inner ring central opening and the slope of the outer wall of the inner ring determine air movement coverage area and magnitude of air velocity in the coverage area generated by a ceiling fan.
