GRID STRUCTURE ON A TRANSMISSIVE LAYER OF AN LED-BASED ILLUMINATION MODULE

摘要

An illumination module (100) includes a plurality of Light Emitting Diodes (LEDs) (102a, 102b, 102c, 102d). A grid structure (196) is present on a transmissive layer (134) 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 (191) while other portions of the pockets are coated with a different type of wavelength converting material (192).
