Title:
LIGHT-OUTPUT DEVICE WITH MOVABLE LIGHT-GUIDE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/131560
Kind Code:
A3
Abstract:
The invention relates to a light-output device (1; 10; 30) controllable to provide different light-output functions. The light-output device comprises a light-source arrangement (12; 31) configured to emit light; and a light-guiding system (10; 32) arranged to receive the light and configured to guide the light to at least one light-output surface of the light-guiding system. The light-guiding system (10; 32) comprises at least a first light-guide (11b; 37) and a second light-guide (11a; 40, 41); and the light-guiding system (10; 32) is movable relative to the light-source arrangement (12; 31) between at least a first position where light output by the light-source arrangement is guided by the first light-guide (11b; 37) to provide a first light-output function, and a second position where light output by the light- source arrangement is guided by the second light-guide (11a; 40, 41) to provide a second light-output function, different from the first light-output function. The present invention is based on the realization that different light-output functions conveniently and intuitively can be achieved by moving a light-guiding system comprising at least two light-guides relative to a stationary light-source arrangement. Hereby, different light-output functions can be achieved with a single stationary light-source arrangement.
