     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     The embodiment of the invention is further described in detail hereinafter, which are illustrated in the drawings, wherein identical or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. In the description of the invention, it should be understood that the terms “upper”, “lower”, “front”, “rear”, “left”, “right”, “inner”, “outer”, “vertical”, “circumferential”, and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience and simplification of description, but do 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 invention. 
     With reference to drawings  1  to  7 , a music arctic starry sky lamp comprises a shell assembly  1 , an auroral assembly  2  arranged in the shell assembly  1  and a laser assembly  3  arranged in the shell assembly  1 ; 
     Said auroral assembly  2  comprises an auroral cover  4 , an auroral piece  5 , a condensing lens  6 , a lens mount  7 , a substrate  8  and a motor  9  which are arranged from top to bottom, said auroral cover  4  is fixedly connected with the shell assembly  1  via screws; said condensing lens  6  is fixedly connected with the lens mount  7 , which is fixedly connected with the substrate  8 ; lamp beads  10  are arranged on said substrate  8 , and said motor  9  is fixedly connected with the substrate  8 , and the output end of said motor  9  penetrates through the substrate  8  and is fixedly connected with the auroral piece  5 ; 
     A plurality of irregular plano-convex lenses  11  are arranged on said auroral cover  4 , the number of which is not less than ten, and not less than two thirds of the irregular plano-convex lenses  11  are irregular long-strip-shaped lenses  12 , and the length of the side edge of each irregular long-strip-shaped lens  12  is more than two times of the width thereof; 
     A plurality of plano-convex lenses  13  are arranged on said auroral piece  5 , the plano-convex lenses  13  are different in size and are irregular in shape, and the focal lengths of said plano-convex lenses  13  are different and the size thereof are smaller than the diameter of the condensing lenses  6 . 
     Said shell assembly  1  includes an upper shell  14  and a bottom shell  15  arranged in combination from top to bottom wherein the top surface of said upper shell  14  is provided with an auroral through-hole  16  penetratingly and said auroral through-hole  16  and auroral cover  4  are used in a cooperative manner; the top surface of said upper shell  14  is provided with a laser through-hole  17  penetratingly, and said laser through-hole  17  and the laser assembly  3  are used in a cooperative manner.
