The invention relates to a 3D heat radiating module type high-power LED illuminating device which comprises at least one detachable high-power LED module, at least one
LED driver, a module fixing device, an
electrical connector and a mechanical connector which are mutually connected into the illuminating device. The illuminating device is characterized in that each detachable high-power LED module comprises at least one high-power LED
single tube, at least one LED radiator, an
electrical connector and a heat radiator fixing device, and all the LED modules are mutually connected and fixed through the module fixing device; all the heat radiators are mutually independently distributed, a lamp body between every two heat radiators is provided with a vent hole through which air can freely circulate, each heat radiator works in a 3D heat radiating environment, the heat radiating efficiency is high, each heat radiator is light and small, the weight of the heat radiator in the prior art is about 100-150g / W, the weight of the 3D heat radiating module type high-power LED illuminating device can be reduced to be below 30g / W, and the LED illuminating device has the advantages of arbitrary
assembly of power size, convenient disassembly and maintenance, good heat
radiation, fewer materials for the heat radiators, high illuminating efficiency, small and light lamps, low cost, long service life and the like and can be used for manufacturing illuminating lamps for shopping malls, roads, tunnels, stages, houses, offices and the like.
