摘要: A method of applying at least two phosphors to an LED, wherein a first phosphor material having a lower absorption, shorter luminescence decay time, and/or lower thermal quenching than a second phosphor material is positioned closer to the LED than the second phosphor. Such an arrangement provides a light emitting device with improved lumen output and color stability over a range of drive currents.

摘要: An improved method for producing optoelectronic devices such as light emitting diodes or laser diodes is provided. Light emitting diodes or laser diodes are provided with improved light extraction. Epitaxial layers including a light emitting p-n junction are deposited on a substrate, and separations are cut through the epitaxial layers to provide a structure including a plurality of individual dies on the substrate. The structure is mounted on a submount and the substrate is removed. An index matching material is then attached to improve light extraction from the optoelectronic device.
