The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it should be noted that when one component is considered to be "connected" to another component, it may be directly connected to the other component or intervening components may exist. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. It should also be noted that, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly and can include, for example, fixed connections, removable connections, or integral connections; either mechanically or electrically, and may be internal to both elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

It should be further noted that in the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

As shown in fig. 1, the utility model discloses a but mechanical light modulation's light 100, including shell 10, lamp shade 20, lamp plate 30 and dimming mechanism 40, lamp shade 20 joint is in the opening part of shell 10, and can be relative shell 10 rotates.
