Light, e.g. for use in chrono-biology, has radiation source(s) attached to reflector adjusted by electromagnetic servo drive in light to vary light distribution/direction by varying rotation angle

摘要

The device has at least one radiation source (1) and at least one light output surface (7). The radiation source is attached to a reflector (4) mounted in the light to rotate about its own longitudinal axis (3). The reflector is adjusted by an electromagnetic servo drive (5) arranged in the light to vary the light distribution and direction of the lighting device by varying the rotation angle.
