Claim 17:
18. An illumination device comprising:
a package comprising (i) a base defining a recessed interior volume and (ii) a transparent lid disposed over the base and covering the interior volume, wherein the base comprises a horizontal first surface disposed below the lid;
a light-emitting device configured to emit ultraviolet (UV) light and disposed within the interior volume;
a first epoxy sealing the lid to the base;
a metallization pattern disposed on the first surface of the base and electrically coupled to the light-emitting device;
one or more voltage-regulation devices (i) disposed within the interior volume and over the first surface of the base and (ii) electrically coupled to the metallization pattern;
a second epoxy attaching at least one said voltage-regulation device to the base, the second epoxy being disposed between and bonding the first surface of the base to a surface of the voltage-regulation device that faces the first surface of the base; and
an opaque encapsulant that encases, to prevent propagation of UV light thereto, (i) an entirety of the at least one said voltage-regulation device, and (ii) an entirety of the second epoxy, the opaque encapsulant also coating a portion of the metallization pattern,
wherein the interior volume is substantially free of oxygen.
