COLOUR MIXING METHOD FOR CONSISTENT COLOUR QUALITY

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.
