    Abstract: A light emitting diode structure includes a substrate and a light emitting unit. The substrate has a protrusion portion and a light guiding portion. The protrusion portion and the light guiding portion have a seamless connection therebetween, and a horizontal projection area of the protrusion portion is smaller than that of the light guiding portion. The light emitting unit is disposed on the protrusion portion of the substrate. The light emitting unit is adapted to emit a light beam, and a portion of the light beam enters the light guiding portion from the protrusion portion and emits from an upper surface of the light guiding portion uncovered by the protrusion portion.

    Abstract: The present invention relates to a light emitting diode (LED) and a flip-chip packaged LED device. The present invention provides an LED device. The LED device is flipped on and connected electrically with a packaging substrate and thus forming the flip-chip packaged LED device. The LED device mainly has an Ohmic-contact layer and a planarized buffer layer between a second-type doping layer and a reflection layer. The Ohmic-contact layer improves the Ohmic-contact characteristics between the second-type doping layer and the reflection layer without affecting the light emitting efficiency of the LED device and the flip-chip packaged LED device. The planarized buffer layer id disposed between the Ohmic-contact layer and the reflection layer for smoothening the Ohmic-contact layer and hence enabling the reflection layer to adhere to the planarized buffer layer smoothly. Thereby, the reflection layer can have the effect of mirror reflection and the scattering phenomenon on the reflected light can be reduced as well.
