Abstract: An optical device for modifying a light distribution is made of transparent material and includes a front wall constituting a front portion, a coupling portion for connecting to a light source system, and side walls between the coupling portion and the front portion. The front wall is configured to let through a first part of light emitted by the light source, and the side walls are configured to let through a second part of the light. The side walls have grooves that refract at least 80% of the second part of the light obliquely rearwards with respect to a direction from the coupling portion to the front portion. Thus, the optical device can be used for illuminating both a floor and a ceiling so that light emitted to unwanted directions and potentially causing glare can be kept at a low level.
