Patent ID: 7083659

Claim:
A combined light source and air purifier unit including: a body ( 11 ); a centrifugal fan ( 12 ) mounted by the body and having an axis which is upright, the centrifugal fan having a central intake ( 17 ) through which air containing contaminants can be drawn from below the unit from a target zone ( 80 ) directly below the intake and extending outwardly by a substantial distance; a light source ( 14 ) mounted by the body, the light source being located radially outside the intake ( 17 ) of the centrifugal fan ( 12 ) so as not to obstruct the flow of air being drawn in use into the intake; a filter ( 13 ) extending circumferentially so that air passing through the fan ( 12 ) and being propelled away by the fan passes through the filter so that contaminants are removed by the filter; and an air discharge ( 60 ) including a discharge path ( 61 ) for air being propelled by the fan, the discharge including flow deflecting means ( 62 ) provided by the body ( 11 ) to deflect air flowing outwardly from the fan in an upwards direction.
