Abstract: The present invention relates to a projection device comprising a body (1) with a projection opening (2) for light projection. The body (1) encloses at least a light source (7), a scanning unit (8) and a deflection unit (3). The deflection unit (3) is mounted movable between an extended position and a non extended position.
