Abstract:
1. A light emitting device, comprising: a plurality of GaN-based light emitting elements monolithically formed on an insulating substrate such that each GaN-based light emitting element comprises portions of GaN-based layers grown on the insulating substrate, a first electrode pad and a second electrode pad disposed on the insulating substrate, wherein the plurality of light emitting elements are disposed between the first electrode pad and the second electrode pad, the plurality of light emitting elements are divided into a first row, second row, and third row electrically connected together in series, the right most light emitting element of the first row and the right most light emitting element of the second row are connected by an electrode comprising a first air bridge line, the left most light emitting element of the second row and the left most light emitting element of the third row are connected by an electrode comprising a second air bridge line, the plurality of light emitting elements are arranged in a two-dimensional pattern on the substrate, the plurality of light emitting elements are grouped into two groups having equal numbers of light emitting elements, an array of light emitting elements in each group is placed in a zigzag pattern, and the two groups of light emitting element arrays are connected between the first electrode pad and the second electrode pad in parallel so that they are of opposite polarities.
