Abstract
Light-emitting diode (LED) packages, and more particularly to a light collector for light mixing in LED packages to improve the far field emission pattern (FFP) of the LED packages are disclosed. The LED package can include one or more LED chips with different wavelength ranges, and the light collector placed over the LED chips can have a reflective surface, save for a reduced aperture through which the light form the LED chips can be emitted after mixing in the light collector. The LED package can also include a lens to further improve the FFP. In an embodiment the light collector can include diffuser material to facilitate the mixing of the light within the light collector. The LED package with the light collector mixes multiple emission point sources into a single point source, or reduced-area source, that considerably improves the FFP of multi-colored LED chips of the LED package.
