Solid-state light source

摘要

A solid-state light source includes at least one stack of light emitting elements. The elements are an inorganic light emitting diode chip and at least one wavelength conversion chip or the elements are a plurality of light emitting diode chips and one or more optional wavelength conversion chips. The wavelength conversion chip may include an electrical interconnection means. The light emitting diode chip may include at least one GaN-based semiconductor layer that is at least ten microns thick and that is fabricated by hydride vapor phase epitaxy. A method is described for fabricating the solid-state light source.
