Method and apparatus for controlling light
First Claim
1. A method of controlling light from one or more central light sources (1) to at least two lighting locations via light conductors (4), said light being conducted from the central light source or sources (1) to a control device (3) comprising a plurality of electrically individually controlled micro-mechanical shutters, each of which has a closed state and an open state, from which the light is conducted further on to the lighting locations via at least two optical guides (4) in the non-closed state of the microshutters.

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.
