To improve the illumination efficiency of hand-held illumination devices, this invention proposes a new illumination device having the 'rolling' function, which is capable of illuminating the target area on which a user is currently focusing and rolling the illuminated area as the user is reading forward or backward. The illumination device comprises two pluralities of lighting elements, an illuminating body and a controller. The controller can control one plurality of lighting elements to emit light to illuminate a part of the illuminating body, which can further deflect the light to a part of the surface of the target.
