The invention discloses a lamp ornament on which an LED (light-emitting diode) luminous sheet group is fixedly arranged. Luminous sheets can emit bright and splendid as well as soft and warm light or other various kinds of light to the outside. Two positioning pins are extended beside an LED on the edge on each luminous sheet. A base fixing the LEDs and the positioning pins is made into various forms, such as a framework, a lamp panel, a decorating part, a structural part, and the like on the lamp ornament. The luminous sheets are arranged along the framework, a back plate, the lamp panel and the structural part, and the plurality of the luminous sheets can be arranged into a wall lamp, a ceiling lamp, a pendant lamp, a floor lamp, a desk lamp, a lawn lamp, a garden lamp, a landscape lamp, a sculpture lamp, a luminous curtain wall, a lamp strip, a surface decorating lamp on a building and other indoor and outdoor lamp ornaments in various shapes. When the base is made into the form of a flower core, various luminous flowers in nature-imitating structure can be produced. The luminous flowers can be made into various sizes and be made into the luminous flowers at the top ends of branches of the branch-shaped pendant lamp, or be made into the lamp ornament independently.
