Light emitting diode, light emitting module and light emitting device

The invention relates to the technical field of light-emitting diode manufacturing, in particular to a light-emitting diode, a light-emitting module and a light-emitting device. The second contact electrode of the light-emitting diode is provided with two special parts with non-linear extension parts, so that an ejector pin operation window is expanded, and the problem that a chip is abnormal due to the fact that the ejector pin bursts a convex area of the contact electrode and is prone to bursting is solved as much as possible; and the problem of non-uniform light emitting of the light emitting diode caused by current change due to position change of the contact electrode can be solved to a certain extent. And meanwhile, under the condition that the shape of the second contact electrode is guaranteed and the current distribution uniformity is improved, a current blocking layer below the extension part of the second contact electrode can be canceled, so that the voltage is reduced under the condition that the
