<p>An illumination device (1) for pixelated illumination of a target area (3) comprising: an array (4) of light emitting devices; projection optics (5) arranged in between the array (4) of light emitting devices and the target area (3); a reflecting structure (6) having a first opening (9) facing the array (4) of light emitting devices and a second opening (10) facing the projection optics (5), and a reflective surface connecting the first and second opening, the surface enclosing and facing an optical axis (11) of the projection optics (5). The projection optics (5) is adapted to image the array (4) of light emitting devices, and a virtual extension thereof created by the reflecting structure (6), onto the target area (3), thereby generating an extended pixelated illumination pattern (2). By utilizing a reflecting structure to create a virtual extension of the array of light emitting devices, a high degree of pixelation can be achieved in the illumination pattern while minimizing the number of light emitting devices required. Thus, increased efficiency and reduce costs can be achieved.</p> |
