Abstract
A luminaire for distributing light from a light source (7). The luminaire includes one or more reflectors (2, 3), placed symmetrically about the lamp (7) to reflect the light output from the lamp (7). One or more light spreading devices (4, 5) are provided around the reflectors (2, 3) to receive the light reflected by the reflectors (2, 3). Such a luminaire provides for uniform distribution of light while minimizing glare from the light fitting.
