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.
