Abstract
An illumination module includes a plurality of Light Emitting Diodes (LEDs). A grid structure is present on a transmissive layer over the LEDs, such as an output window, to form a plurality of color conversion pockets. A portion of the pockets are coated with a first type of wavelength converting material while other portions of the pockets are coated with a different type of wavelength converting material.
