10. A lighting assembly, comprising:

at least one light-emitting diode emitting a light of a first hue in a generally Lambertian radiation pattern;

a bulb fitting over the light-emitting diode, said bulb having a generally spherical shape and a substantially circular external cross-sectional geometry, said bulb defining an inner cavity with a substantially circular cross-sectional geometry for housing the light-emitting diode, said bulb being composed of a light-transmitting material and a first light color-converting material; and

a color-converting insert that is positioned in said inner cavity, said color-converting insert also being composed of a light-transmitting material and including a second light color-converting material, such that said light-emitting diode emits light of the first hue into said color-converting insert, which converts the light of the first hue into light of a second hue, which is then emitted into the bulb, which converts the light of the second hue into light of a desired hue, which is then observed over a light-emitting surface of the bulb.

11. A bulb adapted to fit over and around at least one light-emitting diode emitting a light of a first hue in a predetermined radiation pattern, said bulb being composed of a light-transmitting material and including a light color-converting material, said bulb defining an inner cavity having a cross-sectional geometry based on the predetermined radiation pattern of the light-emitting diode, said bulb including a color-converting insert that is positioned in said inner cavity, said color-converting insert also being composed of a light-transmitting material and including a second light color-converting material, such that said light-emitting diode emits light of the first hue into said color-converting insert, which converts the light of the first hue into light of a second hue, which is then emitted into the bulb, which converts the light of the second hue into light of a desired hue, which is then observed over a light-emitting surface of the bulb.

12. The bulb as recited in claim 11 , wherein the bulb has a generally spherical shape.
