Abstract

This luminair (light fitting) intended for a lamp (2) of linear type mounted fixed in a main reflector section (1) is provided with a screen section (3) made, for example, by assembling prisms, each one of which is parallel to the longitudinal direction of the section, with means (5) allowing this screen to be rotated about an axis (7) parallel to the longitudinal direction of the section. The reflector (1) can also turn about a longitudinal axis. Applications: illumination of a work surface or of horizontally or vertically oriented objects. <IMAGE>
