The invention discloses an adjustable light emitting module and a manufacturing method thereof. The adjustable light emitting module comprises a substrate, at least two light emitting diodes and connecting wires; at least two light emitting diodes are different in power, light color or color temperature; at least two light emitting diodes are arranged on the upper surface of the substrate and areconnected in series through the connecting wires; the two ends of each light-emitting diode are provided with short-circuit connecting sections, and the first ends of the short-circuit connecting sections are connected with the connecting wires; the substrate is provided with a dimming component, and the dimming component is used for connecting the second ends of at least two short-circuit connection sections for short circuit of the corresponding light-emitting diodes, and dimming is achieved. According to the adjustable light-emitting module and the manufacturing method thereof, rapid dimming can be carried out on the same substrate, and the dimming efficiency is improved; moreover, the light source storage cost is omitted, and the labor cost can be effectively saved.
