<p>A lighting appliance of the type designed for enabling the luminous beam produced to be variously oriented, comprising: a) a lamp body (13) with a reflector (20), b) first means (14) for swivelling the lamp body (13) around an first axis (15) pointing substantially towards the area to be illuminated, c) second means (16) for swivelling the lamp body (13) around a second axis (17), lying crosswise to the first axis (15), designed for adjusting the tilting angle of the reflector (20). The first swivelling means (14) consist of a turning pair (22, 23) formed by two component kinematic parts (22, 23). A first part (22) consists of two opposite concave tracks (26a, 26b) with opposite concave sides facing one another and towards said first axis (15). These two tracks (26a, 26b) are elastically deformable and thrusting against the second component part (23) of the turning pair (22-23) so as to generate friction.</p> |
