Device, system and method for illumination of a target area

In an illumination device (6) generating a first cone of light (10) light source (8) and a deflection unit (12) to the beam-forming conversion into a second cone of light (14a, b) and transmitting it to the target surface (4a, b) toward is the deflection unit (12) for changing the shape (Fa, b) and / or the intensity distribution (Ia, b) variable in the second cone of light. An illumination system (2) includes the illumination device (6) and the target surface (4a, b). In a method for illuminating a target surface (4a, b) a light source (8) transmits a first light beam (10) to a deflector (12), the deflection unit (12) converts the first cone of light (10) beam-shaping in a second cone of light (14a , b) and sends it (to the target surface 4a, b) from out the deflector (12) is changed so that the mold (Fa, b) and / or the intensity distribution (Ia, b) (in the second light beam 14a, b is changed). The illumination device (6) or the illumination system (2) for illuminating a surface of an interior of a vehicle as the target surface (4a, b).
