摘要:
Disclosed is a method for packaging an LED by a thermoplastic copolymer. The copolymer is polymerized by 100 parts by weight of an acrylic ester, 0.1 to 30 parts by weight of a hydrogen bond monomer, and 0.1 to 70 parts by weight of a bulky monomer. The copolymer has transparency greater than 90%, thermal resistance greater than 130° C., and moisture absorption less than 0.5 wt %, such that the copolymer may be applied as packaging material for a light emitting device.
摘要:
The disclosed is a copolymer having a formula as: R1 is a combination of naphthalene, phenylene, butyl, and hexyl. R2 is a combination of ethylene, cyclohexlene, 2-methylpropyl, and neopentyl. n is a number of 1500 to 3000. The copolymer has a transparency greater than 80%, a thermal resistance greater than 100, a moisture absorption less than 0.5 wt %, and yellowing under UV/climate resistance greater than 1000 hours, such that the copolymer is adapted to be applied in packaging material for light emitting devices.
摘要:
A method for packaging a light emitting diode is provided. The steps comprise: providing a material; drying the material; feeding the material into a feeding inlet; and providing a mold with pre-embedded light diodes. The material enters the feeding inlet and is injected into the mold by pressing a screw, allowing the material to combine with the light emitting diode.

The disclosed is a blend including 20 to 80 parts by weight of polycarbonate, 20 to 80 parts by weight of polyarylate, and 20 to 80 parts by weight of copolymer having a formula as below: wherein R1 is a combination of at least two of ethylene, cyclohexlene dimethylene, 2-methyl propyl, and neopentyl. R2 is a combination of at least two of naphthalene, phenylene, butyl, and hexyl. n is a number of 1500 to 3000. The blend has high transparency, high thermal resistance, and high yellowing resistance under UV/climate, such that the blend is suitable to be applied in packaging material for light emitting device.
摘要:
The invention provides an organic/inorganic hybrid material and the method for manufacturing the same. A variety of functional monomers are co-polymerized to form a copolymer. The copolymer is subjected to sol-gel reactions with metal alkoxide oligomers to form an organic/inorganic hybrid material. The hybrid material has a high refractive index, a low moisture absorption, a high light transmission ratio, and a high glass transition point, such that the material can be applied in high light extraction efficient LED sealing materials, thin and light myopia/hypropia lens, portable projector lens, high brightness LCD prism films, solar cell refractive photoelectric conversion mirrors, and camera phone/digital camera lens.
