NOVELTY - This utility new type claims a one high radiating a high light efficiency low light decay of large power LED, comprising radiating device, substrate and LED chip, a radiating device surrounding the base plate in the periphery of the LED chip packaging distribute a of a substrate. A base plate surface set with a silver coating, contact surface of base plate surface and silver coating a concavo-convex groove surface, of the LED chip surface in turn set with a graphene modified fluorescent powder glue layer and graphene modified silicon glue layer, the graphene modified fluorescent powder glue layer by fluorescent powder, silicon glue and compose the graphene, the graphene modified silicon glue layer by graphite and silicon glue compose. This utility new type one of a high radiating a high light efficiency low light decay of large power LED with radiating property, light effect and high light attenuation low of.
