Abstract: A lamp including a light source, a reflective unit and a light modulation module is provided. The light source provides an illuminating light, and the reflective unit reflects the illuminating light. The light modulation module is disposed between the light source and the reflective unit. In the light modulation module, a region where movable light absorbing materials exist is a light absorbing region, and a region where the movable light absorbing materials are absent is a light penetration region. By applying different electrical fields to the movable light absorbing materials, sizes and locations of the light absorbing region and the light penetration region can be changed. A portion of the illuminating light irradiating the light penetration region penetrates through the light penetration region, is transmitted to the reflective unit, being reflected by the reflective unit, and penetrates through the light penetration region again sequentially.
