Abstract: An optical device for modifying a light distribution pattern of a light source is presented. The light source radiates first light beams to a first geometric quarter-space and second light beams to a second geometric quarter-space, where the first and second quarter-spaces are defined by mutually perpendicular geometric planes one of which constitutes a boundary between the first and second geometric quarter-spaces. The optical device includes a lens-section for modifying a light distribution pattern of the first light beams and two reflector surfaces for reflecting the second light beams from the second geometric quarter-space to the first geometric quarter-space. The two reflector surfaces are successively in a direction perpendicular to the boundary between the first and second geometric quarter-spaces and make it possible that the optical device can be lower than in a case where only one reflector surface is used.
