NOVELTY - This utility new type claims a one large power LED graphite alkenyl radiating device, comprising an LED light source adhered to the bottom is used for conducting heat of substrate, the upper substrate is set with a heat radiating effect of fin, the bottom of substrate is set with a single-layer graphene interface, of the LED light source bottom and a contact interface is single layer graphene interface fill with graphene and the adhesive is a composite layer. This utility new type single layer graphite alkenyl interface horizontal direction has a high heat conductivity, a heat of the concentrated mass and is transmitted to the corrugated design and reasonable distributing of substrate and fins, fin, increase the convection heat exchange ability of the fin and the air, so as to set a large amount of rapid heat conduction, convection and heat exchange radiating; the radiating heat efficiency is high, heat radiating effect is good, the heat sink temperature uniformity.
