A light source (10) includes a light emitting component (32), such as a
UV/blue light emitting diode or laser diode, a layer (46) of a light
scattering material (42), and a layer (48) of a phosphor material (44).
The phosphor material converts a portion of the light emitted by the light
emitting component to light of a longer wavelength, such as yellow light.
The scattering material scatters the light emitted by the light emitting
component and/or the light converted by the phosphor to improve the
overall uniformity of the angular distribution of the light. When
combined, the converted and scattered light has a more uniform angular
distribution, that is, it maintains the approximately the same color as
the viewing angle is changed.
