Abstract: The present invention relates to a light emitting module, which comprises: a main body; a common terminal, in which one side of the common terminal is exposed to the main body and a weldless coupling structure is disposed on the bottom of the common terminal; at least a control terminal, in which one side of the control terminal is exposed to the main body and a weldless coupling structure is disposed on the bottom of the control terminal; and at least a light emitting device. When assembling the components mentioned above, the common terminal and the control terminal are inserted into a through hole of a printed circuit board (PCB), such that the structure can be inlaid into the through hole and a better contact is obtained by its elasticity. Accordingly, the light emitting module can be fastened on the PCB.
