Abstract:
1. A light-emitting device comprising: a mounting area including a first end and a second end opposite to the first end; a first electrode group adjacent to the first end of the mounting area; a second electrode group adjacent to the second end of the mounting area; a first file in that a plurality of light-emitting elements are arranged in the mounting area to extend from a vicinity of the first end of the mounting area to a vicinity of the second end of the mounting area and electrically connected in series with each other of the light-emitting elements of the first file; a second file disposed at a right side of the first file in parallel with the first file, the second file in that a plurality of light-emitting elements are arranged in the mounting area to extend from the vicinity of the first end of the mounting area to the vicinity of the second end of the mounting area and electrically connected in series with each other of the light-emitting elements of the second file; a third file disposed at a left side of the first file in parallel with the first file, the third file in that a plurality of light-emitting elements are arranged in the mounting area to extend from the vicinity of the first end of the mounting area to the vicinity of the second end of the mounting area and electrically connected in series with each other of the light-emitting elements of the third file; and a fourth file in that a plurality of light-emitting elements are arranged in the mounting area to extend from the vicinity of the first end of the mounting area to the vicinity of the second end of the mounting area and electrically connected in series with each other of the light-emitting elements of the fourth file, the first electrode group including a first electrode and a second electrode that are disposed adjacent to the first end of the mounting area, and the second electrode group including a first electrode as a transit electrode, a first light-emitting element included in the second file and positioned adjacent to the first end of the mounting area being electrically connected in series to the first electrode of the first electrode group, and a second light-emitting element included in the second file and positioned adjacent to the second end of the mounting area being electrically connected in series to the first electrode of the second electrode group, a first light-emitting element included in the third file and positioned adjacent to the first end of the mounting area being electrically connected in series to the second electrode of the first electrode group, and a second light-emitting element included in the third file and positioned adjacent to the second end of the mounting area being electrically connected in series to the first electrode of the second electrode group, the first electrode group including electrodes that are configured to be two or more entries of electrical current to the light-emitting elements arranged in the mounting area, the first electrode group further including a third electrode and a fourth electrode; the second electrode group further including a second electrode, and a first light-emitting element of the plurality of light-emitting elements included in the first file and positioned adjacent to the first end of the mounting area being electrically connected in series to the third electrode of the first electrode group, and a second light-emitting element of the plurality of light-emitting elements included in the first file and positioned adjacent to the second end of the mounting area being electrically connected in series to the second electrode of the second electrode group.
