Uv led package

Abstract

A UV LED package disclosed herein includes a submount, a UV LED chip adapted to emit UV light at 200 nm to 400 nm, and a package body mounted with the submount. The submount includes a heat dissipating substrate, a first reflective electrode film and a second reflective electrode film separated from each other by an electrode separation gap on the heat dissipating substrate, a first flip-chip bonding pad and a first wire bonding pad disposed on the first reflective electrode film, and a second flip-chip bonding pad and a second wire bonding pad disposed on the second reflective electrode film. The UV LED chip includes a first conductive electrode pad corresponding to the first flip-chip bonding pad and a second conductive electrode pad corresponding to the second flip-chip bonding pad. The UV LED chip is flip-chip bonded to the submount through a first bonding bump interposed between the first flip-chip bonding pad and the first conductive electrode pad and a second bonding bump interposed between the second flip-chip bonding pad and the second conductive electrode pad. The package body includes a first metal body electrically connected to the first wire bonding pad through a first bonding wire and a second metal body separated from the first metal body by an insulating material and electrically connected to the second wire bonding pad through a second bonding wire.
