Light-emitting device

A light-emitting device comprising:

• a light source comprising:
• a plurality of light-emitting parts, each having a first main surface serving as a light-exiting surface, and a second main surface on a side opposite the first main surface, and each comprising a first electrode and a second electrode at the second main surface, and
• a covering member integrally holding the plurality of light-emitting parts such that the first electrode and the second electrode are exposed from the covering member, wherein:
• the plurality of light-emitting parts are configured to be turned on individually or as a group and are arranged in a first direction and a second direction intersecting the first direction;
• and
• a substrate having an upper surface and comprising, at the upper surface:
• a plurality of first wiring portions, each of which is opposed to a corresponding one of the first electrodes of the light-emitting parts, and
• a plurality of second wiring portions, each of which is opposed to a corresponding one of the second electrodes of the light-emitting parts;
• wherein:
• the plurality of light-emitting parts comprise one or more first light-emitting parts disposed at a center area in a top view, and a plurality of second light-emitting parts disposed outward of the one or more first light-emitting parts in a top view,
• the plurality of light-emitting parts are operable in a first irradiation mode in which only the one or more first light-emitting parts emit light at a predetermined output, and
• one of the first wiring portions connected to one of the one or more first light-emitting part is continuous through a first wiring connection portion with two or more of the first wiring portions connected to two or more of the second light-emitting parts that are adjacent to said one of the one or more first light-emitting parts.
