Abstract
In order to provide a pleasing aesthetic appearance, and also in order to enable concealed, directional lighting to be used, an openword grid-like suspended ceiling system has outer squares which contain four inner blades forming an inner square surrounded by four rectangles. Light fittings are associated with the rectangles so that the axis of a light fitting can be inclined. In order to enable the ceiling system to be packaged at low packing density, the four inner blades are hinged to each other and collapse so as to lie parallel to each other. After opening out, they can be hooked into the sides of the outer squares.
