An optoelectronic component has a lens that is formed in the surface of an encapsulant surrounding a semiconductor diode element. With respect to emitters, the lens reduces internal reflection and reduces dispersion to increase overall efficiency. With respect to detectors, the lens focuses photons on...http://www.google.es/patents/US7067893?utm_source=gb-gplus-sharePatente US7067893 - Optoelectronic element with a non-protruding lens
