Description
Technical field
The invention belongs to field of new, the more particularly to preparation method of LED diffusion light-guidings composite plate.
Background technology
With the increasingly fierceness of market competition, the competitive advantage of oneself product, thing U.S. valency are being sought by various businessmans and manufacturer
It is honest and clean to be undoubtedly the market mainstream.The light guide plate and diffuser plate that are applied to LED panel illumination at present are two separate products, with reference to one
Rise and use, light guide panel material is PMMA, diffuser panel material is PMMA, PS or PC, belongs to separately fabricated product.Led in production
, it is necessary to two complete equipments are produced respectively when light sheet material and diffusion sheet material, low production efficiency, the production cost of light guide plate and diffuser plate compared with
Height, therefore the price of the product such as LED flat plate light fixture, circular luminaire is difficult to reduce, it is difficult to meet the quality-high and inexpensive demand of consumer.
Additionally, the light guide plate of LED illumination also has material cost with diffuser plate larger, heavier-weight, the big office of thickness
It is sex-limited.The light guide plate minimum thickness applied at present in LED illumination is 3mm, and diffuser plate minimum thickness is 1.5mm, and both add up to
4.5mm.Because LED illumination product is generally the upper mounting means in top, influenceed by natural gravity, too thin too soft plastic material has downslide
Possibility, and the material such as PMMA, PC plastified within 1mm, be relatively easy to deformation, it is damaged the features such as, so no matter
On cost or in structure, all there is bottleneck in LED area light source light fixture.
Patent of invention CN102975370A discloses the production method and equipment of a kind of optical composite sheet material, its production method
Including：Guide-lighting raw material and diffuser material are plastified respectively；In guide-lighting raw material and diffuser material feeding mould after by plasticizing
Co-extrusion is carried out, flexible glue shape sheet material is formed；To from mould out after flexible glue shape sheet material carry out press polish and embossing molding.The invention
The production method of optical composite sheet material, it is raw compared to total production procedure of existing light guide plate and diffuser plate in production procedure
Producing flow reduces half, and production efficiency greatly improved, but the material to composite board is not improved, such compound
Plate remains cracky, the shortcoming of deformation.
