Abstract
An optical arrangement comprises a reflector (2) of parabolic outline which cooperates with one or more reflectors (3, 5, 6) of elliptical outline to direct light beams in a direction which preferably forms an angle of between 40 to 50 DEG with the axis (XY) on which are situated the focus (F) of the source and the focus (F1) of the parabola. The arrangement may be mounted in a framework with the possible addition of means to enable the various reflectors to be individually positioned in relation, to the source.
