Lighting device with switchable light sources

A lighting device comprising: a main element (1105) comprising a central axis (1002); a rotating cylinder (1103) that surrounds at least a part of the main element (1105) and adapted to rotate concentrically around the central axis (1002); a lens (1504) which is asymmetrically arranged in the rotating cylinder (1103) and is adapted to rotate with the rotating cylinder (1103), the lens (1504) comprising an input (1602) of light off-center with respect to the central axis (1002) ); and a plurality of light sources that are fixed relative to the main member (1105), wherein rotation of the rotary cylinder (1103) relative to the main member (1105) causes the light input (1602) to rotate to along an arc around the central axis (1002) to selectively align different light sources with the light input (1602).
