NOVELTY - The utility model claims an LED radiator technical field, especially relates to a dot-matrix type LED radiator of adding graphene material. The technique program adopted by the utility model is to provide a matrix-type LED radiator adding graphene material; the radiator comprises dandelion-shaped heat sink, several radiating rib of the radiating fin comprises a cylindrical main body and extending outward from the cylindrical main body, further comprising a graphite radiating core is located in said cylindrical main body is cylindrical, the outwardly extending several radiating rib bends clockwise along the outermost dispersed into 2 sub-rib. The utility model has the following advantages: 1. The rotation angle and increasing sub-rib of mode, which increases the contact area of the LED lamp radiating fin, and benefits to promote the heat dissipation efficiency; 2. uses graphene as the hot core, at reduced weight and greatly improves the radiating efficiency; 3. Compared with the active radiating type LED lamp has good economical efficiency.
