Abstract

A fluorescent lighting tube is located within the reflector that has an element that provides a diffusing effect to prevent a dazzling effect being provided. The reflector is produced of a pair of two half shells (2,3) with a parabolic profile. The fluorescent tube is located at the focal point of the reflector. Positioned in front of the tube is a reflector (17) in the form of a perforated (18) plate. The width of the plate is sized to provide an effective angle corresponding to the boundary points (18) of the parabolic reflectors. An alternative version utilises an asymmetric reflector element.
