Patent ID: 8188489

Claim:
A light emitting diode (LED), comprising: a plurality of light emitting cells arranged on a substrate; at least four half-wave light emitting units each comprising at least one light emitting cell, each half-wave light emitting unit comprising a first terminal and a second terminal respectively arranged at both ends thereof; and at least two full-wave light emitting units each comprising at least one light emitting cell, each full-wave light emitting unit comprising a third terminal and a fourth terminal respectively arranged at both ends thereof, wherein the third terminal of at least one full-wave light emitting unit is electrically connected to the second terminals of two half-wave light emitting units, and the fourth terminal of the at least one full-wave light emitting unit is electrically connected to the first terminals of other two half-wave light emitting units; and wherein a first half-wave light emitting unit is connected in series between the third terminal of a first full-wave light emitting unit and the fourth terminal of a second full-wave light emitting unit, and a second half-wave light emitting unit is connected in series between the fourth terminal of the first full-wave light emitting unit and the third terminal of the second full-wave light emitting unit.
