Abstract
The invention provides a special polycarbonate light-diffusion material for the outer cover of an LED (light-emitting diode) lamp and a preparation method for the same. The special polycarbonate light-diffusion material for the outer cover of the LED lamp comprises the following components in percentage by weight: 70-85% of PC (polycarbonate) resin, 10-20% of PMMA (polymethyl methacrylate), 1-10% of GPPS (general purpose polystyrene) and 1-5% of compatilizer. The preparation method provided by the invention comprises the following steps of: performing complex blending polymerization on the PC resin and the PMMA with the best transparency, different light refractive indexes and undefined compatibility, using necessary auxiliaries for matching with the PC resin and the PMMA, and obtaining the excellent LED light-diffusion material via a special production workshop, special equipment and a meticulous production process.
Description
Technical field
The invention belongs to the LED field, particularly a kind of LED lamp outer cover is with photodiffusion material and preparation method thereof.
Background technology
The LED lamp of power saving environmental protection and energy saving, energy-conservation about 40%, but and environmental protection recycle.This is pursuing a high-tech project with demand in the whole world just always, estimates soon in the future, will replace existing general lighting and get into huge numbers of families, for the mankind benefit.
Led technology is broken through, in generally using, during wherein heat dissipation base part material is is also just progressively researched and developed, tried out.LED light is strong, dazzling, luminous energy is very high.How to make LED light become bright and soft, and light loss is again little, this is that industry is paid close attention to always.Briefly: how penetrate local cover the last layer not only light harvesting but also the structural film layer that can spread at LED light; The material of this layer structural film layer must light weight, heat-resisting, light transmission good, can play diffusion especially.Existing thin-film material, its effect is unsatisfactory.
