    Abstract: Methods, apparatus and systems are described herein. A light source includes a first light emitting diode (LED) die configured to emit a first die color and a second LED die configured to emit a second die color. A first filling is disposed over the first LED die. The first filling has a convex surface and includes a first phosphor such that the first die color is converted to a first illuminous color. A second filling is disposed over the second LED die. The second filling includes a second phosphor such that the second die color is converted to a second illuminous color that has a higher absorption energy than an illumination energy of the first illuminous color.
