Bulb for light-emitting diode with color-converting insert
First Claim
1. A bulb adapted to fit over at least one light-emitting diode emitting a light of a first hue in a predetermined radiation pattern, the bulb being composed of a light-transmitting material, the bulb having a generally spherical shape with a substantially circular external cross-sectional geometry, the bulb defining an inner cavity with a cross-sectional geometry based on the predetermined radiation pattern of the light-emitting diode, and the 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 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 desired hue, which is then observed over a light-emitting surface of the bulb.

Abstract
A bulb is adapted to fit over a light-emitting diode emitting a light of a first hue. The bulb is composed of a light-transmitting material and defines an inner cavity. The bulb includes a color-converting insert that is positioned in the inner cavity. The color-converting insert is also composed of a light-transmitting material and includes a light color-converting material. The light-emitting diode emits light of the first hue into the color-converting insert, which converts the light of the first hue into light of a desired hue, which is then emitted into the bulb and ultimately observed over a light-emitting surface of the bulb.
