Description
Technical field
The present invention relates to a kind of optics to spread anti-dazzle structure and preparation method thereof, belongs to technical field of LED illumination.
Background technology
High-quality LED area light source needs high uniformity of luminance, high light emission efficiency.Since LED itself is light
Source, the realization of area source are the diffusions for first building pointolite array, then carrying out light, just LED point light source can be made to become to compare in this way
Uniform area source.In order to realize high energy utilization, the total reflection during light outgoing need to be reduced as far as possible, while lamps and lanterns are also
Meet the requirement of anti-dazzle.
Dazzle is a kind of visual experience, i.e., usually said " twinkling ".International lighting association is to the anti-dazzle finger of the unification of lamps and lanterns
Number (UGR) is distinctly claimed --- and lamps and lanterns must satisfy UGR < 19." a kind of anti-dazzle that 204829356 U of patent CN are mentioned
Panel light ", structure include backboard, EVA, reflector plate, light guide plate, optical diaphragm and diffuser plate successively；Patent CN 206378615
A kind of efficient diffusion barrier that U is mentioned, including base material are provided with diffusion layer on base material two sides, are additionally provided on interior side diffusion layer
The staggered anti-dazzle photosphere of micro-structure；A kind of prism diffuser plate that 107167856 A of patent CN are mentioned, structure include substrate,
Micro-prism structure and diffusion layer.The multilayered structure combination of above-mentioned patent can not make UGR is up to standard to reach (i.e. UGR < 19) completely, and
Complex process, production cost are higher.
Invention content
In order to overcome the deficiencies of the prior art, the present invention is directed to propose a kind of optics spreads anti-dazzle structure, and one is provided simultaneously
The kind optics spreads the preparation method of anti-dazzle structure.The present invention makes single layer micro-structure in the one side of transparent base and spreads antiglare layer, should
Anti-dazzle light effect and diffusion effect can be combined into one by diffusion antiglare layer, integrated molding, and preparation process is simple.
Single layer micro-structure diffusion antiglare layer of the present invention is the transparent convex spherical cap-shaped structure of random arrangement, convex spherical crown
Tangent or nearest back gauge is no more than 8 μm between the spherical crown of shape structure.The spherical crown of convex spherical cap-shaped structure is single-size, and diameter is situated between
Between 20 μm -50 μm, between 25 μm -40 μm.The structural integrity is molded, and is prepared by imprint process.
Transparent base thickness is the membrane material or plank of 0.5mm-3mm.Wherein membrane material can be PET, PEN, PC or transparent PI etc.
Any one of, plank can be any one of glass, PMMA, PC or PS etc..
The material that single layer micro-structure spreads antiglare layer is transparent coining glue, can be thermoplastic polymer, thermosetting property polymerization
One of object and UV curable polymers are integrally formed, are prepared over the transparent substrate by imprint process.Preparation method
Include the following steps：
I. by the way of self assembly micro-sphere structure is obtained in the one side of substrate.Microballoon is single-size, close each other
Arrangement；
II. it uses reverse mould technique to make the recessed spherical cap-shaped structure with micro-sphere structure complementation, forms template.Reverse mould technique can be with
It is stamping technique or photoetching combination microelectroforming technology.
III. so that transparent coining glue is formed convex spherical cap-shaped structure using stamping technique --- i.e. single layer micro-structure diffusion is anti-dazzle
Layer.
The invention has the characteristics that and good result：
Only need common diffuser plate is replaced using this anti-dazzle diffuser plate in LED lamp, can reach not only spread but also
The purpose of anti-dazzle (UGR < 19), and it is of low cost, it can extensive use.
The preparation method of the diffusion antiglare layer, including above-mentioned step I-III, preparation process is simple, can large area production.
Using the recessed spherical cap-shaped structure template in step II, commercial quantities factory can directly be carried out by stamping technique.
The specific embodiment of the invention is described in detail below in conjunction with attached drawing, will become more apparent to one of ordinary skill in the art
The technical characteristic of the present invention.
