The translucent three-dimensional sculpture lamp cover is prepared from resin, flame retardant, graphene, fluorescent powder, Ciba 754 (RTM: oxy-phenyl-acetic acid 2-(2-oxo-2-phenyl-acetoxy-ethoxy)- ethyl ester), polyetheramine catalyst, Chinese medicine essential oil, active mineral powder, cerium oxide, modified aromatic amine curing agent and glass fiber. USE - Three-dimensional sculpture light-emitting diode decorative lighting is used in hotel and home decoration. ADVANTAGE - The three-dimensional sculpture light-emitting diode decorative lighting has function of releasing anion, favorable removal rate of formaldehyde, toluene and total volatile organic compound, and excellent artistic effect. DETAILED DESCRIPTION - A three-dimensional sculpture light-emitting diode (LED) decorative lighting comprises a translucent three-dimensional sculpture lamp cover, a LED lighting assembly, a base and a power supply driving device provided in the base. The lamp cover has a hollow cavity for housing the LED lighting assembly. Heat-radiating holes are formed in the side wall of the hollow cavity, a heat-dissipation coating is applied to the inner surface of the side wall of the hollow cavity. The translucent three-dimensional sculpture lamp cover is prepared by adding 50-65 pts. wt. resin, 5-8 pts. wt. flame retardant, 3-4.5 pts. wt. graphene, 0.1-0.3 pt. wt. fluorescent powder, 2-4 pts. wt. Ciba 754 (RTM: oxy-phenyl-acetic acid 2-(2-oxo-2-phenyl-acetoxy-ethoxy)- ethyl ester) photoinitiator and 0.5-0.7 pt. wt. polyetheramine catalyst to a mixer, concentrating at 70-80 degrees C under high-speed mixing, stirring for 15-30 minutes, obtaining mixture (A), placing 50-60 pts. wt. Lappula, 3-5 pts. wt. Lycopodii, 20-25 pts. wt. Capillaris, 15-20 pts. wt. lavender, 3-5 pts. wt. Anemone hupehensis, 3-5 pts. wt. Fallopia multiflora, 1.5-2.5 pts. wt. sweet marjoram, 1-3 pts. wt. Cimicifuga, 3-5 pts. wt. marigold and 6-8 pts. wt. camphor leaves in a vacuum oven at -20 degrees C for 2-3 hours, placing resultant mixture in a microwave dryer, drying at microwave power of 17 kW for 30-40 minutes, grinding to 60 mesh, obtaining bulk drug powder, adding the drug powder to an extraction vessel of a supercritical carbon dioxide extraction apparatus, extracting at 45 degrees C for 2 hours under pressure of 27.65 MPa with carbon dioxide flow rate of 1100 L/hour, collecting crude oil, freezing crude oil in an environment of 5 degrees C for 70 minutes, centrifuging frozen crude oil in a high-speed refrigerated centrifuge at 17000 rpm for 25 minutes, removing impurities, placing resultant oil in a vacuum box at 85 degrees C for 3 hours, obtaining volatile oil (B), washing 1.5-2 pts. wt. vanilla, 3-4 pts. wt. purslane, 4-4.5 pts. wt. Salvia miltiorrhiza, 2-3 pts. wt. Polygonum hydropiper, 3-4 pts. wt. Agastache rugosa, 3-4 pts. wt. Stellera chamaejasme, 6-7.5 pts. wt. Stemona japonica and 3-4 pts. wt. Artemisia, drying, crushing to 30 mesh, immersing obtained powder in deionized water for 5 hours, adding water, stirring, dispersing, obtaining Chinese medicine mixture, decanting Chinese medicine mixture at 80 degrees C for 2 hours, extracting distillate with diethyl ether, collecting upper oil phase, adding 0.13-0.3 pt. wt. anhydrous sodium sulfate, drying, obtaining volatile oil (C), mixing volatile oil (B) and volatile oil (C), adding white peony essential oil, cypress essential oil, snow lotus essential oil, Eucalyptus essential oil and blue chamomile essential oil to mixed oil, stirring for 45 minutes, aging for 30 minutes, filtering, obtaining Chinese medicine essential oil, mixing 1-1.2 pt. wt. Chinese medicine essential oil and mixture (A), concentrating, stirring at 70-80 degrees C for 30 minutes, obtaining mixture (D), adding mixture (D) to a ball mill, adding 0.7-1 pt. wt. active mineral powder, 0.1-0.15 pt. wt. cerium oxide, 3-4 pts. wt. modified aromatic amine curing agent and 10-20 pts. wt. glass fiber, grinding at 70-80 degrees C for 4.5 hours, filtering to remove impurities, adding obtained premix to a twin screw extruder, extruding at 260-280 degrees C and speed of 150-250 rpm, cooling, pelletizing, heating obtained composite material in an injection molding machine, extruding, molding, cooling, and trimming. The mass ratio of mixed oil, white peony essential oil, cypress essential oil, snow lotus essential oil, Eucalyptus essential oil and blue chamomile essential oil is 2:0.6:0.5:0.65:0.5:0.45. The volume ratio of distillate and diethyl ether is 2.5:1. The resin is a mixture of epoxidized soybean oil acrylate And bisphenol A-type E51 epoxy resin in a mass ratio of 2:1-3:2. The flame retardant is a mixture of ammonium polyphosphate, melamine and intumescent graphite in a mass ratio of 2:1.5:1.3. The fluorescent powder is cerium and yttrium aluminum garnet mixture, and has particle size of 13 mu m or less.
