A lighting installation comprises a number of vertical strips (7) mounted in a window bay (2) and pivotable about their central axis to prevent the passage of direct light, together with fluorescent tubes (23) controlled by photocells (5) to vary the light intensity in dependence on the overall level. Each tube (23) is shielded from below by a metal strip (11) of, for example anodised aluminium and provided with an overhead reflector of polished aluminium to reflect light through a grill (26) suspended between the metal strips (11). The grill is made of vertical interlocked plastic strips, a suitable shade of grey and of a height and mesh of 20 mm. The ceiling (4) is painted matt white. The system provides diffuse lighting and avoids direct light or glare. |
