Abstract: The present invention relates to a color variable light emitting device (100; 200; 300; 400) comprising at least one light source (101; 201; 303; 401) and at least one deformable element (102; 202; 301; 402). The deformable element (102; 202; 301; 402) comprises particles of at least one wavelength converting material (103; 203; 305; 403) and the element (102; 202; 301; 402) is arranged to receive light from the at least one light source (101; 201; 303; 401) and to convert it into light of a different wavelength. Since the element comprising the wavelength converting material(s) is deformable, the thickness of the element can be varied. This thickness variation allows for the wavelength converting material, and hence also the color, to be tuned.

Abstract: The present invention relates to a lighting system (100) comprising at least one light source (101), a light guide (102) which is arranged to receive light emitted by the light source(s) (101) and at least one light extracting member (103). The light extracting member(s) (103) is adapted to extract light from the light guide, and is removably arranged on a surface of the light guide (102). The light extracting member is removably arranged on the light guide meaning that it may be detached from and moved to a different position on the light guide. Light may thus be extracted at any desired position, and this allows for a controlled and variable extraction of light.
