摘要：
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.
