LED lamp radiator

The utility model relates to a radiator of the LED illumination fitting, in particular to a columnar radiator of the LED illumination fitting with via-hole. The radiator of the LED illumination fitting provided by the utility model can be used for the radiation of the big power LED. The radiator is columnar, and the top of the column is a mounting platform of the LED. A plurality of via-holes are arranged along the axial line of the radiator around the LED mounting area of the mounting platform. And the LED wiring holes are arranged on the mounting platform. The radiator of the LED illumination fitting of the utility model has rapid radiating speed, and solves the problem of the radiation of the big power LED by using the technology of air convection, heat exchange and heat radiation; the structure is simple and reasonable, and the radiation efficiency is high by using the natural convection; the manufacture is convenient with low cost and good radiation effect.
