The utility model provides a light-reflecting cup of a multi-layer step type tunnel lamp, which belongs to the field of light-emitting diode (LED) tunnel lighting devices. The light-reflecting cup structurally comprises a base. A blind hole is vertically arranged at the center of the base, and the lateral wall of the blind hole is in a step inner wall shape. The width of the step inner wall is reduced progressively from top to bottom, and a light-reflecting surface is arranged on the vertical surface of the step inner wall. A front surface plate is arranged along the periphery of the blind hole at the upper end of the base, namely the upper end of the blind hole. The front surface plate is formed by connecting four plate bodies in end-to-end mode, pits are arranged in the middle of the four plate bodies, and clamp springs are symmetrically arranged on the base below the front surface plate. Compared with the prior art, the light-reflecting cup has the advantages of being reasonable in design, simple in struct
