Abstract
The invention relates to a light emitting diode (LED) module that is characterized by a thermally conductive substrate which is used as the base of the module; and a plurality of cavities positioned on the module; and a plurality of LED semiconductors chips are mounted within each cavity. Within each cavity; secondary cavities are formed and a plurality of LED semiconductors chips are mounted within each of the secondary cavity. A multiple layer configuration of encapsulation is used to fill the cavities to help mix and diffuse the light from the LED chips and ensure that we achieve a uniform light output from the light emitting surface of the module.
