| 摘要 |
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.
