A bulb adapted to fit over and around a light-emitting diode emitting a light of a first hue in a predetermined radiation pattern defines an inner cavity for housing the light-emitting diode with a cross-sectional geometry based on the predetermined radiation pattern of the light-emitting diode. The bulb is composed of a light-transmitting material and a light color-converting material, with the light color-converting material converting the light of the first hue into light of a desired hue, which is then viewed over a light-emitting surface of the bulb.

1. A bulb adapted to fit over and around a light-emitting diode emitting a light of a first hue in a predetermined radiation pattern, the bulb defining an inner cavity for housing the light-emitting diode having a cross-sectional geometry based on the predetermined radiation pattern of the light-emitting diode, and the bulb being composed of a light-transmitting material and a light color-converting material, said light color-converting material converting the light of the first hue into a light of a desired hue, which is then viewed over a light-emitting surface of the bulb, wherein, as a result of the cross-sectional geometry of the inner cavity defined by the bulb, at a point of maximum brightness in the predetermined radiation pattern of the light-emitting diode, the light of the first hue will pass through a greatest amount of said light color-converting material, while as brightness decreases in the predetermined radiation pattern of the light-emitting diode, the light of the first hue will pass through a lesser amount of said light color-converting material. 2. The bulb as recited in claim 1, wherein the bulb has a generally spherical shape. 3. The bulb as recited in claim 1, wherein the predetermined radiation pattern is a generally Lambertian radiation pattern. 4. The bulb as recited in claim 3, wherein the bulb has a generally spherical shape. 5. The bulb as recited in claim 1, wherein said light color-converting material is one or more fluorescent dyes. 6. The bulb as recited in claim 1, wherein said light color-converting material is one or more phosphorescent dyes. 7. The bulb as recited in claim 1, wherein said light color-converting material is a combination of fluorescent dyes and/or phosphorescent dyes. 8. The bulb as recited in claim 1, wherein said light-transmitting material is an acrylic resin. 9. The bulb as recited in claim 8, wherein said light color-converting material is one or more fluorescent dyes mixed into said acrylic resin. 10. The bulb as recited in claim 1, wherein the cross-sectional geometry for the inner cavity of the bulb is plotted by: transposing the predetermined radiation pattern of the light-emitting diode onto an x-y coordinate system;superimposing the bulb onto the x-y coordinate system, with the inner cavity of the bulb initially having a generally circular cross-section defining a boundary;measuring a radial distance that the predetermined radiation pattern extends past the light-emitting surface of the bulb at selected angles on the x-y coordinate system; andadding the measured radial distance at each selected angle to the generally circular cross-section of the inner cavity, extending the boundary of the inner cavity at each selected angle to plot the cross-sectional geometry for the inner cavity. 11. A lighting assembly, comprising a light-emitting diode emitting a light of a first hue in a predetermined radiation pattern; anda bulb fitting over and around the light-emitting diode, the bulb defining an inner cavity for housing the light-emitting diode having a cross-sectional geometry based on the predetermined radiation pattern of the light-emitting diode, and the bulb being composed of a light-transmitting material and a light color-converting material, said light color-converting material converting the light of the first hue into a light of a desired hue, which is then viewed over a light-emitting surface of the bulb, wherein, as a result of the cross-sectional geometry of the inner cavity defined by the bulb, at a point of maximum brightness in the predetermined radiation pattern of the light-emitting diode, the light of the first hue will pass through a greatest amount of said light color-converting material, while as brightness decreases in the predetermined radiation pattern of the light-emitting diode, the light of the first hue will pass through a lesser amount of said light color-converting material. 12. The lighting assembly as recited in claim 11, wherein the bulb has a generally spherical shape. 13. The lighting assembly as recited in claim 11, wherein the predetermined radiation pattern is a generally Lambertian radiation pattern. 14. The lighting assembly as recited in claim 13, wherein the bulb has a generally spherical shape. 15. The lighting assembly as recited in claim 11, wherein said light color-converting material is one or more fluorescent dyes. 16. The lighting assembly as recited in claim 11, wherein said light color-converting material is one or more phosphorescent dyes. 17. The lighting assembly as recited in claim 11, wherein said light color-converting material is a combination of fluorescent dyes and/or phosphorescent dyes. 18.
