Beschreibung
Zusammenfassung:	Segmented LED arrays with various diffusing elements are disclosed. An example segmented LED array includes a plurality of LEDs arranged in a plurality of sections where a given section may include one or more LEDs and where each section may be aligned with a different respective optical element such as a lens. Each LED may be a wavelength-converting LED in that it may include a light emitter arrangement and a wavelength-converter structure. In various embodiments, diffusing elements in the form of one or more structures of a diffuser material may be provided over the wavelength-converter structure of one or more LEDs, the one or more structures being in a light path between the wavelength-converter structure and at least one of the plurality of optical elements, and configured to diffuse light emerging from the wavelength-converter structure.
