ILLUMINATION DEVICE

原文（中国語）

An illumination device includes an asymmetric laser light source, a beam adjustment module and an anisotropic diffusion module. The asymmetric laser light source is adapted to output an illumination light beam having different sizes in a first direction and a second direction that are interlaced with each other. The beam adjustment module is adapted to adjust a beam size of the illumination light beam. The anisotropic diffusion module is disposed between the asymmetric laser light source and the beam adjustment module. The anisotropic diffusion module has different optical properties along the first direction and the second direction, and the beam size of the illumination light beam is consistent in the first direction and the second direction.
