Abstract
An apparatus for diffusing light and for directing circulation of air. A support (3), a grill panel (2) and a socket (12) are mounted together to form the apparatus. The support (30) is mounted to a base (64, 68). A nozzle (94) within the base (64, 68) creates a venturi effect by providing an emerging airstream which causes air to flow upward through the grill panel and then out to mix with the emerging air-stream. The grill panel (2) is cleaned of particulate matter because of the flow of the air through the grill panel. The emerging airstream travels in the same direction that it travelled when passing from the inlet to the outlet of the nozzle.
