LIGHT-EMITTING DEVICE WITH REFLECTIVE CERAMIC SUBSTRATE

摘要

A light-emitting device may include a ceramic substrate having a reflective component, a light-emitting diode on the ceramic substrate, and a light-converting material over the light-emitting diode. A lighting system may include a ceramic substrate having a reflective component, a plurality of light-emitting diodes connected together in series, wherein the plurality of light-emitting diodes are on the ceramic substrate, and a light-converting material over the plurality of light-emitting diodes. The ceramic substrate may provide electrical insulation between the light-emitting diode and the aluminum carrier. The ceramic substrate may provide thermal conductivity between the light-emitting diode and the aluminum carrier. The reflective component may include zirconium oxide. The ceramic substrate may include aluminum oxide and/or aluminum nitride. The light-converting material may include phosphor. The light-emitting diode may have an epitaxial diode structure.
