The utility model relates to a multi-stage type reflector (1), which is characterized in that the multi-stage type reflector (1) comprises a reflecting shell (10) with a first opening (110) and a second opening (120), and at least two sections of annular surfaces (20), which are formed on the internal surface of the reflecting shell (10) and are formed by two symmetric busbars by rotating around the same one symmetric axis, wherein the tilt angles of the annular surfaces relative to the axial direction are different; the tilt angles of the annular surfaces (20) relative to the axial direction are gradually reduced along the direction from the first opening (110) to the second opening (120) of the multi-stage type reflector (1); a plurality of small patches (210) are formed on the annular surfaces (20), wherein the small patches (210) have the similar or different gradients, orientations and/or curvatures, so that the uniformity of the emitting light of the lighting device and the control of the light emitting angle can be realized.
