  • Publication number: 20240085775
    Abstract: An illumination device includes: a plurality of light source assemblies; and a plate-shaped optical unit on which light source light beams from the plurality of light source assemblies are incident from mutually different directions, and the plate-shaped optical unit is sectioned into a reflection surface and a transmission surface in accordance with an incident light intensity distribution of each of the light source light beams. Then, transmitted light having passed through the plate-shaped optical unit among the light source light beams and reflected light having been reflected by the plate-shaped optical unit among the light source light beams are emitted with directions aligned, and a boundary between the transmission surface and the reflection surface in the plate-shaped optical unit is formed at a position where incident light intensities of the light source light beams individually from the plurality of light source assemblies have substantially equal values to each other.
