Abstract:
1. A flip-chip light emitting diode package structure, comprising: a submount having a first surface and a second surface opposite to the first surface, an indentation on the first surface, a plurality of grooves on a first sidewall and a second sidewall of the submount; a first patterned conductive reflection film disposed on a first part of the first surface, a first part of the second surface, a first part of a sidewall of the indention, a first part of a bottom of the indentation and a part of an inner wall of the grooves; a second patterned conductive reflection film on a second part of the first surface, a second part of the second surface, a second part of the sidewall of the indention and a second part of the bottom of the indentation, and a remaining part of the inner wall of the grooves; and a light emitting diode (LED) chip inside the indentation of the submount, wherein the LED chip has two electrodes electrically connecting with the first patterned conductive reflection film and the second patterned conductive reflection film, respectively, wherein the first patterned conductive reflection film and the second patterned conductive reflection film cover the entire first surface except for a narrow insulation gap between the first patterned conductive reflection film and the second patterned conductive reflection film.
