Abstract: A device for a projector to adaptively receive lamps of different sizes. The device includes a fixing element for fixing a lamp to a support structure of the fixing element. The lamp having a lamp tang. The fixing element provides a locking mechanism for the lamp and is adapted to receive at least two different diameters of lamp tangs. The fixing element for the lamp is movable between at least two positions, to adapt to a focal distance of a specific lamp.

Abstract: The invention relates to a lifting apparatus, particularly for lighting fittings. The lifting apparatus comprises a pair of pantograph structures which are spaced apart, substantially parallel, and facing each other. The lifting apparatus further includes a suspension coupling and means at the bottom thereof for coupling the fitting to be lifted. Motorization means to operate both the parallelogram structures are provided between the two parallelogram structures. Connection means associated with the motorization means are associated with each one of the parallelogram structures.
