Abstract: The present invention relates to a lighting device (1) that comprises a first light source (2) comprising one or more LED devices (21). At least a deformable reflective element (3) is optically coupled to said first light source, so as to receive light from said first light source, said reflective structure comprising at least a first portion (31) having a reflective surface (310) that reflects at least partially the light (L1) received from said first light source, and a second portion (32) that is solidly coupled to said first portion. Driving means (4) are operatively coupled to said second portion (32), which induce a deformation of said second portion that in turn causes a deformation of the reflective surface (310) of said first portion. The position of the focus point (F) of the light (L2) reflected by said reflective surface can thus be varied in a controlled manner.
