Abstract
A wavelength-converting plate for a wavelength-converted light emitting diode (LED) assembly. The wavelength-converting plate includes microlenses deposited thereon. The microlenses may have an index of refraction different from the index of refraction of the wavelength-converting plate. The microlenses on the top surface of the plate increase lumen output in a direction normal to the top surface of a wavelength-converting plate.
