The utility model relates to a light-emitting diode (LED) signal lamp module used for a back light. The LED signal lamp module used for the back light comprises a drive circuit board, at least three light emitting diodes and a light matching lens, wherein the at least three light emitting diodes are fixed on the drive circuit board, the drive circuit board is installed on the front side of the light matching lens, the light matching lens is provided with a lower light matching lens surface, a rear light matching lens surface and a coupling surface, the lower light matching lens surface is arranged on the bottom of the light matching lens, the rear light matching lens surface is a curved surface, the coupling surface is arranged on the front portion of the light matching lens, and each light emitting diode on the drive circuit board is arranged on the front side of the coupling surface. The LED signal lamp module used for the back light has the advantages of being compact in structure, capable of shortening de
