摘要
An illumination device includes a light source, an optical film, and a drive module. The optical film has a plurality of optical regions, each having a light incident surface opposite to the light source and a light emitting surface opposite to the light incident surface, and at least one of each of the light incident and emitting surfaces has a micro-structure. The drive module moves the optical film in the space, and light emitted by the light source passes through the different optical regions of the optical film, changing the distribution curve of luminous intensity of the light source.
