ABSTRACT:
Light is emitted from a light emitting device. The light emitted from the light emitting device is combined with light from a first type of phosphor and a second type of phosphor. The first type of phosphor and the second type of phosphor are within an epoxy placed over the light emitting device. The first type of phosphor, when excited, emits light of a first color. The second type of phosphor, when excited, emits light of a second color. The first color and the second color are different.
