摘要： A batwing beam is produced from an LED package having a primary LED lens by molding the LED lens directly over an LED on a package substrate. The LED lens includes a cavity over a center of the LED. The cavity surface reflects light from the LED through total internal reflection (TIR) or through a reflectivity gel coating. The cavity may be a cone or a pyramid.

摘要： An optical emitter includes micro-structure phosphor coating on a light-emitting diode die mounted on a package substrate. The micro-structures are transferred onto a micro-structure phosphor coating precursor by patterning and curing the precursor or by curing the precursor through a mold. The micro-structures are half spheroids, three-sided pyramids, or six-sided pyramids.
