Claim 0:
1. A light source, comprising:
a substrate;
a first light emitting diode (LED) die having a bottom surface on the substrate and configured to emit light having a first die color when turned on;
a first dome-shaped filling completely surrounding all surfaces of the first LED die except the bottom surface, the first filling comprising a first phosphor such that the light having the first die color is converted to light having a first illuminous color when the first LED die is turned on;
a second LED die spaced apart from the first LED die, having a bottom surface on the substrate, and configured to emit light having a second die color when the second LED die is turned on; and
a second filling completely surrounding all surfaces of the second LED die except the bottom surface and extending to the first dome-shaped filling while leaving at least a portion of a top surface of the first dome-shaped filling exposed from the second filling, the second filling comprising a second phosphor such that, when the first and second LED dies are turned on, the light having the second die color is converted to light having a second illuminous color that has a higher absorption energy than an illumination energy of the first illuminous color and passes around the first dome-shaped filling unconverted by the first dome-shaped filling.
