Abstract:
An optic assembly for a light emitting diode mounted to a printed circuit board has a primary lens defined by a primary lens anterior surface and an opposed primary lens rear taper with a tip facing the light emitting diode. A secondary lens with a secondary lens anterior surface and an opposed secondary lens posterior surface faces the printed circuit board. The secondary lens defines a central cavity with the primary lens being disposed therein.
