A packaged UV-LED device comprises a die carrier member having a cup-shaped recess, a fused silica lens member that is anodic bonded to the die carrier member, and a UV-LED die that is flip-chip mounted within a sealed cavity formed by the carrier member and the lens member. The carrier member involves a unitary cup member fashioned in an economical way from monocrystalline silicon wafer material. A dielectric/aluminum reflector that is effective for UV radiation and that does not degrade and overheat is disposed on the sidewalls of the recess. The lens member is anodic bonded to a silicon surface of the rim of this unitary cup member at a time when the UV-LED die is disposed in the recess. The anodic bonding is done in such way that the die is not damaged and such that the entire packaged UV-LED device includes no UV-degradable adhesive.
