Abstract:
The present invention relates to a light emitting device (1) comprising a stack of a light emitting diode (LED) structure (10) and a light permeable device (20). The light permeable device (20) comprises at least a first and a second section (21, 22), color of light from said first and second section (21, 22) being different from each other. Further, the LED structure (10) comprises at least a first and a second region (11, 12) being individually controllable. The first and second region (11, 12) are associated with the first and second section (21, 22), respectively. The stack further comprises an at least partially reflecting layer (30) arranged such that light from the light permeable device (20), generated in the first and second region (11, 12), is to be mixed within the light emitting device (1).
