Abstract

<P>The lighting unit has a main reflector (1) formed from two identical reflector shells (11,2) that are located symmetrically about a centre axis (2). Located within the main reflector is an auxiliary reflector unit (4) that has a pair of surfaces (41,42). The lighting tube (5) is positioned between the surfaces. The auxiliary reflector arrangement and the lighting tube can be moved vertically (6) to vary the effect. The auxiliary reflector provides an indirect lighting effect.
