1. A light-emitting device comprising:
a mounting board having an upper surface provided with a device-mounting pattern thereon;
a plurality of light-emitting elements, each of which is a flip-chip light-emitting element that is mounted on the device-mounting pattern and connected in series and/or in parallel through the device-mounting pattern; and
at least one wire electrically connecting a part of the device-mounting pattern to another part of the device-mounting pattern,
wherein the device-mounting pattern comprises a plurality of wire connection regions, each of the wire connection regions being spaced apart from each other at a distance such that the connection regions are connected by the wire extending between the connection regions to alter one of a plurality of connection patterns by a wire connection between some of the plurality of wire connection regions while an interconnection between the plurality of light-emitting elements are kept unchanged, each of the plurality of connection patterns has different numbers of series connection and parallel connection of the light-emitting elements,
wherein the at least one wire connects the wire connection regions jumping over at least a part of the device-mounting pattern,
wherein a plurality of rows of the light-emitting elements are disposed on the device-mounting pattern, each row of the rows of the light-emitting elements being formed of a part of the light-emitting elements, and
wherein the device-mounting pattern is not interposed between any adjacent rows of the plurality of rows of the light-emitting elements except for a connection between adjacent light-emitting elements.
