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.
