An exemplary illumination device includes a light source, a flexible light transmissive film and a driving module. The light source is for emitting light. The flexible light transmissive film has a substantially rectangular shape. The flexible light transmissive film is divided into a plurality of optical wavelength converting regions successively arranged along a longitudinal direction of the rectangular shape. The driving module is mechanically connected to at least one end of the light transmissive film and configured for winding up the light transmissive film, thereby driving the light transmissive film to travel along the longitudinal direction.
