Light emitting, photovoltaic or other electronic apparatus and system

摘要

The present invention provides an electronic apparatus, such as a lighting device comprised of light emitting diodes (LEDs) or a power generating apparatus comprising photovoltaic diodes, which may be created through a printing process, using a semiconductor or other substrate particle ink or suspension and using a lens particle ink or suspension. An exemplary apparatus comprises a base; at least one first conductor; a plurality of diodes coupled to the at least one first conductor; at least one second conductor coupled to the plurality of diodes; and a plurality of lenses suspended in a polymer deposited or attached over the diodes. The lenses and the suspending polymer have different indices of refraction. In some embodiments, the lenses and diodes are substantially spherical, and have a ratio of mean diameters or lengths between about 10:1 and 2:1. The diodes may be LEDs or photovoltaic diodes, and in some embodiments, have a junction formed at least partially as a hemispherical shell or cap.

主权项

1. An apparatus, comprising:
a plurality of first conductors; a plurality of diodes coupled to the plurality of first conductors, wherein fifteen percent to fifty-five percent of a surface of each diode of substantially all of the plurality of diodes has a penetration layer or region having a first majority carrier or dopant and the remaining eighty-five percent to forty-five percent of the surface of each diode and diode substrate of substantially all of the plurality of diodes has a second majority carrier or dopant, wherein a mean size of the plurality of diodes is between twenty microns and forty microns; a plurality of second conductors coupled to the plurality of diodes; and a lens structure.
