Abstract: The invention is an illumination unit for point illumination of a medium where at least one light emitter is arranged to illuminate at least one illumination face via a first lens arrangement and a microshutter arrangement. The lens arrangement has at least one microlens arranged with respect to each microshutter so that light emitted from the light emitter is focused on or in the vicinity of the optical axis of the light channel of the individual microshutters. The fed coherent light from the light emitters is modulated by the microshutters onto the illumination face.

Abstract: The invention relates to a method and an apparatus for controlling light from a light source (1) to a lighting location. A preferred embodiment of the invention comprises precisely one central light source (1) which is connected to a plurality of light guides (4) via a control unit (3), each of said light guides being terminated at a remote point. The control unit comprises a plurality of electrically controlled microshutters (14, 15), each of which has at least two states, an open state and a closed state, from which the light is conducted further on to the light location or locations via optical guides in the open state of the diaphragms. The light may thus be distributed by means of the control unit (3) to the individual light guides (4) in response to control signals supplied to the control unit.
