Abstract
A light emitting diode (LED) lighting apparatus including an array of first optic elements overlying an array of LED chips, wherein each of the LED chips is configured to emit light of a first wavelength range through a light emitting surface of the overlying first optic element. The array of first optic elements are also underlying an array of second optic elements, wherein each of the second optic elements is configured to convert light of the first wavelength range to be emitted through the light emitting surface of the underlying first optic element to light of a second wavelength range different from the first wavelength range.
