1. A light emitting diode (LED) filament comprising:
a first plurality of LED dies that emit light within a first range of wavelengths; and
a second plurality of LED dies that emit light within a second range of wavelengths,
wherein the first range of wavelengths and the second range of wavelengths do not overlap, and wherein the first plurality of LED dies and the second plurality of LED dies are arranged in a staggered manner along a length of the LED filament, the first plurality of LED dies and the second plurality of LED dies being non-adjacent to one another in a first direction parallel to the length of the LED filament and in a second direction perpendicular to the length of the LED filament.
