The invention discloses an LED rice-shaped lamp which consists of a polygonal column, LED lamp slices, retaining screws, a pressure plate, a controller, a connecting line, a bottom plate and contact pins, wherein the polygonal column adopts a metal framework structure, and the center of the framework is hollow; each LED lamp slice is composed of a flat-panel LED lamp and a protective film; and the LED lamp slices are mounted at the periphery and the top end of the polygonal column, and are fixed to the upper surface of the polygonal column framework through the retaining screws and the pressure plate. The controller is composed of a rectifying circuit and a regulating circuit, and the controller is arranged at the upper end of the bottom plate; the metal contact pins pass through the bottom plate; the contact pin at the upper end of the bottom plate is connected to the input end of the controller, and the contact pin at the lower end of the bottom plate is a power plug of the LED lamp; and the output end of the controller is connected to the LED lamp slices. The LED rice-shaped lamp can be a common lamp or a color modulation lamp, wherein the common lamp has two pins; and the color modulation lamp has multiple pins. The polygonal column, the retaining screws and the pressure plate are made of metal materials and are used as radiating plates. The LED rice-shaped lamp can replace a current halogen rice-shaped lamp, is energy-saving and environmentally-friendly, and is long in service life.
