    • Disclosed is a light emitting diode having a plurality of light emitting cells. The light emitting diode comprises half-wave light emitting units each of which has at least one light emitting cell and a first and a second terminal, and full-wave light emitting units each of which has at least one light emitting cell and a third terminal and a fourth terminal. The third terminals of the full-wave light emitting units are electrically and commonly connected to the second terminals of two half-wave light emitting units, and the fourth terminals of the full-wave light emitting units are electrically and commonly connected to the first terminals of another two half-wave light emitting units. Further, one of the half-wave light emitting units is connected in series between the third terminal of one of said two full-wave light emitting units disposed adjacent to each other and the fourth terminal of the other of the two full-wave light emitting units. Another half-wave light emitting unit is connected in series between the fourth terminal of one of said two full-wave light emitting units and the third terminal of the other of the two-full wave light emitting units. Whereby, the efficiency of using light emitting cells can be improved, and a light emitting diode which is stable to reverse voltage can be obtained.
    • 公开了具有多个发光单元的发光二极管。 发光二极管包括半波发光单元,每个发光单元具有至少一个发光单元和第一和第二端子,全波发光单元各自具有至少一个发光单元和第三端子 和第四终端。 全波发光单元的第三端子电连接到两个半波发光单元的第二端子,并且全波发光单元的第四端子电连接到第一端子 的另外两个半波发光单元。 此外,半波发光单元中的一个串联连接在彼此相邻布置的所述两个全波发光单元中的一个的第三端子和两个全波发光区域中的另一个的第四端子 单位。 另一个半波发光单元串联连接在所述两个全波发光单元之一的第四端与两全波发光单元中另一个的第三端之间。 由此,可以提高使用发光单元的效率,可以获得对反向电压稳定的发光二极管。
