ABSTRACT:
A surgical light (10) includes a conical shaped reflector (12) which is formed from pre-finished sheet of reflector material into a conical shape. The conical reflector (12) reflects the light from a lamp (14) at a plurality of different angles. Light directly from the lamp and reflected from the reflector strikes a refractor (18) at a plurality of angles of incidence which vary with distance from a central axis (X) of the reflector. The refractor has a plurality of differently shaped prisms (20) whose shape varies with the distance from the central axis to redirect the light to an illumination zone (Z).
