Abstract: The luminaire has a housing (1), a mounting bracket (3) and a coupling (4) to connect the housing adjustably with the bracket (3). The coupling (4) has a first part (10) secured to the housing (1), a second part (20) fixed to the bracket (3) and a blocking device (5), the first and the second parts (10, 20) being nested and coupled. The blocking device (5) may have a blocking member (12, 14) coupled to one of the parts (10, 20) and a seat (21, 22) therefor in the other of the parts (10, 20). The coupling (4) allows for rotating the housing (1) from its adjusted position and to bring it back into its original position without the need to adjust it again.
