<p>The device (130) has a compensation unit (133) i.e. piezoelectric spacer, expanded such that the unit compensates thermal effects for affecting a geometry of a light beam emitted by a lighting and/or signaling device (100). Displacement of expansion of the compensation unit is directly applied at a point of an optical module element (3). The compensation unit is in mechanical connection with the element and remotely positioned from an axis (140) around which the element is articulated such that expansion effort of the compensation unit creates torque around the axis. An independent claim is also included for a method for controlling a lighting and/or signaling device.</p> |
