Mingtai Surgery lamp reflector includes a plurality of reflection rings sequentially stacked from bottom to top, the radius of the horizontal cross-section of each reflection ring decreases from bottom to top, each reflection ring is composed of a plurality of reflecting surfaces with six sides and is connected in turn 360 degrees in the horizontal direction around the centerline of the reflector. Each reflection surfaces of the reflection ring are the same, and each reflecting surface is connected with adjacent reflecting surface through a common overlapping edge. Therefore, any reflecting surface must be divided into two symmetrical halves by a longitudinal section containing the center line and passing through two opposite ends of the reflecting surface. In any two adjacent reflection rings, the two oblique edges at the lower end of any reflection surface of the previous reflection ring respectively coincide and have the same length with one oblique edge on the upper ends of two adjacent reflection surfaces of the next reflection ring. Such a beneficial effect is that the reflected light is more evenly distributed, reflection focusing better, not easy to cause visual fatigue, and improve the rigidity of the reflector, the reflector is not easy to deform.
