Abstract
Embodiments of the invention include a semiconductor light emitting diode attached to a substrate. A first region of wavelength converting material is disposed on the substrate. The wavelength converting material is configured to absorb light emitted by the semiconductor light emitting diode and emit light at a different wavelength. In the first region, the wavelength converting material coats an entire surface of the substrate. The substrate is disposed proximate a bottom surface of an optical cavity. A second region of wavelength converting material is disposed proximate a top surface of the optical cavity.
