A mounting arrangement for an electric lighting unit formed with two relatively slidable members 3, 4 comprises means for hinging or suspending the member 3 from a fixed support such as a false ceiling 1 and controlling means, such as an arrangement of a cable and pulleys, providing movement of the two members to and from a normal substantially horizontal position at which the members are in register from and to a vertical position whereat the member 4 extends downwardly from the hinged member 3. The cable 12 passes from a manually or electrically operated winch over a pulley 11A secured to a main ceiling 2 to a pulley 10C on the free end of the member 3 then to two pulleys 10B, 10A on the hinged end of the member 3 and then round a pulley 9C on one end of the slidable member 4, the end of the cable being secured to the false ceiling near the hinge 3a. Drawing in the cable causes the slidable member 4 to be translated upwardly into register with the member 3 and then the two members pivot about the hinge 3a until they reach the horizontal position and fit into a recess in the false ceiling. A manual or automatic catch holds the fitting in this position. The degree of outward sliding movement of the slidable member 4 from the hinged member 3 may be limited by stops to less than the length of either ; but alternatively the slidable member 4 may become completely disengaged from the hinged member 3 and may also be disengageable from the cable. The slidable member may comprise a louvre or a glazing frame. Elongated lamps may be mounted in either member and may be connected to the electric supply by plug and socket connectors arranged to be automatically engaged when the two members 3, 4 of the fitting are in register. Electrical equipment such as ballasts may be mounted in either member or in the main ceiling 2.
