    摘要: A packaging method for light emitting diodes provides both high light extraction and heat dissipation using a transparent vertical stand structure. A light emitting diode (LED) is attached to a vertical stand structure for supporting the LED, wherein the LED is bonded to the vertical stand structure, so that one of the LED's sides faces vertically upwards, another of the LED's sides faces vertically downwards, a top surface of the LED faces horizontally sideways in one direction, and a bottom surface of the LED faces horizontally sideways in another direction. The vertical stand structure comprises a connecting stem between the LED and a header, and is made of a material that provides for heat dissipation and may also be transparent to light generated in the LED, such as sapphire or zinc oxide. The LED and the vertical stand structure may be encapsulated within a mold.

    摘要: A light emitting diode (LED) device structure with a reduced Droop effect, and a method for fabricating the LED device structure. The LED is a III-nitride-based LED having an active layer or emitting layer comprised of a multi-quantum-well (MQW) structure, wherein there are eight or more quantum wells (QWs) in the MQW structure, and more preferably, at least nine QWs in the MQW structure. Moreover, the QWs in the MQW structure are grown at temperatures different from barrier layers in the MQW structure, wherein the barrier layers in the MQW structure are grown a temperatures at least 40° C. higher than the QWs in the MQW structure.
