An exemplary illumination device includes a solid-state light source and an anti-glare plate. The solid-state light source is configured for generating light, and the solid-state light source defines a central axis. The anti-glare plate is arranged correspondingly generally adjacent to the solid-state light source. The plate includes an incident surface and an output surface at opposite sides thereof. The output surface has parallel micro-structures each have a length parallel to a first reference axis, and the micro-structures is arranged in two groups at opposite sides of the central axis. The micro-structures are configured for contracting a radiating range of the light entering the plate. Such contraction is along respective opposite directions of a second reference axis, and the second reference axis is substantially perpendicular to the first reference axis. |
