Abstract

The lamp (10) is of the type comprising a vertical column (11) and supports one (46) or more lighting fixtures. It comprises a lower element (20) for its support on the floor (12) and an upper element (46; 54) for its support on the ceiling (14), and two coaxial intermediate tubular elements (16, 18) insertable one into the other in the manner of a telescope and lockable together by a known device providing locking and release as the result of relative rotation of the two tubular elements (16, 18) in one direction or the other respectively. At least one lighting fixture (46) is rigid with at least one (18) of the two tubular elements. Within the column (11) there is provided an elastic device (22) which, as a result of axial compression of the column (11), enables the length of the lamp (10) to be shortened in order to enable the locking-release device to be released. With the lamp (10) mounted, the elastic device (22) develops an axial force sufficient to maintain the lamp (10) stable but without preventing a person being able, by acting on the column (11) with the hands, to overcome the elastic force developed by the elastic device (22) in order to release the lamp (10). <IMAGE>
