Claim Text:
1. A light-emitting device, comprising: a single substrate; at least two light-emitting units disposed on the single substrate, each of the at least two light-emitting units comprising: a node connected to a portion of the at least two light-emitting units, wherein: the at least two light-emitting units each comprise a half-wave light-emitting unit or a full-wave light-emitting unit; two light-emitting units of the at least two light-emitting units each comprise full-wave light-emitting units, and share the first conductivity-type semiconductor layer; the other light-emitting units besides the two full-wave light-emitting units of the at least two light-emitting units comprise half-wave light-emitting units; the half-wave light-emitting units each comprise a first terminal and a second terminal; the full-wave light-emitting units each comprise a third terminal having the same polarity as the first terminal and a fourth terminal having the same polarity as the second terminal; the third terminal of each full-wave light-emitting unit is connected to the second terminal of adjacent half-wave light-emitting units and the fourth terminal of each full-wave light-emitting unit is connected to the first terminal of adjacent half-wave light emitting units; the two full-wave light-emitting units are disposed on opposite sides of the node; two half-wave light-emitting units of the half-wave light-emitting units are disposed on opposite sides of the node; and the node comprises the shared the first conductivity-type semiconductor layer.
