Combined light source and air purifier

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.
