摘要: The present invention relates to a light emitting device (100; 300; 400; 500) comprising at least two light emitting diodes (101; 301; 401; 501) and a first optical layer (102; 302; 402; 502) comprising a plurality of lenses (103; 303). The first optical layer (102; 302; 402; 502) is directly illuminated by the light emitting diodes (101; 301; 401; 501) and is adapted to create a plurality of images (104) of the light emitting diodes (101; 301; 401; 501). A device of the present invention provides an improved color quality in the far-field and is suitable for large area applications.

摘要: There is disclosed a lighting device of which the light sources and/or optical elements are hidden in a first cover state associated with a first light state. This enables an unobtrusive lighting system in the first cover state. In a second cover state associated with a second light state, optical elements, e.g. shutters or beam shaping elements, are switched, induced by the heat or the light flux generated by the light sources, such that the lighting system can function properly.
