Patent ID: 8109656

Claim:
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.
