Light-emitting unit and semiconductor light-emitting device

A light-emitting unit, comprising:

• a first pad on a mounting substrate;
• a second pad on the mounting substrate and spaced from the first pad in a first direction along the mounting substrate;
• at least one third pad between the first pad and the second pad along the first direction;
• and
• a semiconductor light-emitting device comprising a resin layer supporting a plurality of light-emitting elements each respectively having first and second external terminals which extend through the resin layer to a first surface of the resin layer facing the mounting substrate, wherein
• each third pad has the second external terminal of one light-emitting element in the plurality and the first external terminal of another light-emitting element in the plurality disposed thereon.

A semiconductor light-emitting device, comprising:

• a plurality of light-emitting elements each of which includes a first electrode and a second electrode separated in a first direction, the plurality including:
• a first light-emitting element disposed at a first end of the semiconductor light-emitting device along the first direction;
• and
• a second light-emitting element disposed at a second end of the semiconductor light-emitting device along the first direction;
• a resin layer integrally supporting the plurality of light-emitting elements;
• a first external terminal connected to a first electrode of the first light-emitting element;
• a second external terminal connected to a second electrode of the second light-emitting element;
• and
• a third external terminal between the first external terminal and the second external terminal along the first direction, the third external terminal being connecting in common to a first electrode of a one light-emitting element in the plurality of light-emitting elements and a second electrode of another light-emitting element in the plurality that is adjacent in the first direction to the one light-emitting element in the plurality of light-emitting elements.
