The lamp (1) has a deflecting element e.g. rotation symmetric lens, arranged before a light source (100) e.g. LED, in a direction of a radiated light. The deflecting element is provided symmetrical relative to a symmetrical reference i.e. symmetrical axis, and deflects light rays coming from the source. A positioning unit positions the source outside the symmetrical reference so that a light cone delivered by the lamp is variable in an outer space (A). A casing surface of the lens is coated with a reflective coating. The light source is designed with a point-shaped radiation point (1000). An independent claim is also included for a method for positioning and/or varying radiated and/or reflected light of a lamp. |
