DETAILED DESCRIPTION - A high-heat-dissipation light-emitting-diode bulb assembly has lampshade, light-emitting-diode lighting component, aluminum-based printed circuit board, heat sink, power driving module and lamp holder. The power driving module is provided within base. The heat sink has a heat conducting plate, hollow thermal conductive column and heat-radiating fins. The lampshade and heat-radiating fins are connected by buckle. The lamp holder is fixed at lower end of radiating fin. A heat-radiating coating is provided between thermal pad and aluminum-based printed circuit board. The hollow thermal conductive column comprises silicon carbide material. Radiating vents are arranged on surface of hollow thermal conductive column. The heat conducting plate and hollow thermal conductive column are arranged in hollow cavity of heat dissipating fin. The radiating grooves are arranged on sidewall of radiating fin. The heat dissipation slot penetrates the sidewall of heat radiating fin. A heat-dissipating paint is uniformly coated on inner wall and outer wall surface of hollow heat-conducting column. The heat-radiating coating comprises 60-75 pts. wt. mixed resin, 5-6.5 pts. wt. graphene, 3-4.5 pts. wt. sodium montmorillonite, 4-6.5 pts. wt. carboxylated styrene-butadiene latex, 1.5-2 pts. wt. silicone methyl branched silicone oil, 0.7-1.2 pts. wt. polyethylene glycol, 0.7-1.8 pts. wt. n-pentane, 1-2.5 pts. wt. nano-silica, 7-9 pts. wt. polyacrylonitrile-based carbon fibers, 1-2 pts. wt. fumed silica, 5.5-7 pts. wt. flame retardant, 4-6 pts. wt. modified aromatic amine curing agent, 15-20 pts. wt. solvent, 0.1-0.15 pt. wt. ceria, 1.5-2 pts. wt. activated mineral powder, and 1.5-2.5 pts. wt. Chinese medicine essential oil. The mixed resin comprises phenolic resin and epoxy resin in mass ratio of 2:1-3:1. The polyacrylonitrile-based carbon fibers have length of 0.01 mm. The flame retardant comprises ammonium polyphosphate, melamine and expanded graphite in mass ratio of 2:1.5:1.3. The solvent comprises diacetone alcohol and butyl ester in mass ratio of 3:1-3:2.
