<p>A lighting device comprises at least one light source (2) and a body (3) that is respectively movable between a first position at which it conceals the light source (2) that is generally turned off to the sight of an observer, and a second position at which it makes visible the light source (2) that is turned on. The device further comprises actuating means (4) associated with said movable body (3) and including at least one shape memory actuator (5) that is selectively deformable between a first geometric condition corresponding to the first position of the movable body (3) in which the light radiation is absent, and a second geometric condition corresponding to the second position of the movable body (3) in which the light radiation is present.</p> |
