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.
