• a bottom shell plate provided with an accommodation groove, wherein the accommodation groove is formed according to a path of a predetermined design and has an inner cavity contour and an inner wall;
• an integrally formed light-emitting panel having a shape matching the inner cavity contour of the accommodation groove and provided with a light-emitting device, the light-emitting panel being entirely placed within the accommodation groove;
• a lamp cover covering the accommodation groove and being connected to the bottom shell plate;
• wherein the lamp cover comprises:
• a covered part located around an outer periphery of a side wall of the accommodation groove and abutting against the side wall of the accommodation groove to constrain a position of the lamp cover itself;
• and
• wherein the light-emitting panel is accommodated within the accommodation groove, such that the lamp cover, through the abutment of the covered part with the side wall of the accommodation groove, constrains the light-emitting panel within the accommodation groove.

A decorative lamp, comprising:

• an integrally injection-molded base plate, wherein a top surface of the base plate is provided with two sets of upward-extending side walls that jointly enclose to form a lamp groove, and the lamp groove is formed according to a path of a predetermined design and has an inner cavity contour and inner walls;
• an integrally formed light panel having a shape matching the inner cavity contour of the lamp groove and being provided with a light-emitting element, the light panel being entirely placed within the lamp groove;
• a lampshade covering the lamp groove and being connected to the base plate;
• wherein the lampshade comprises:
• an embedded part located within the lamp groove and abutting against the inner wall of the lamp groove to constrain a position of the lampshade itself;
• and
• wherein the light panel is accommodated within the lamp groove, such that the lampshade, through the abutment of the embedded part with the inner wall of the lamp groove, constrains the light panel within the lamp groove.
