Abstract
A semiconductor structure includes a module with a plurality of die regions, a plurality of light-emitting devices disposed upon the substrate so that each of the die regions includes one of the light-emitting devices, and a lens board over the module and adhered to the substrate with glue. The lens board includes a plurality of microlenses each corresponding to one of the die regions, and at each one of the die regions the glue provides an air-tight encapsulation of one of the light-emitting devices by a respective one of the microlenses. Further, phosphor is included as a part of the lens board.
